Using Chitosan/CHPATC as coagulant to remove color and turbidity of industrial wastewater: Optimization through RSM design

One of the most important solid-liquid separation processes is coagulation and flocculation that is extensively used in the primary treatment of industrial wastewater. The biopolymers, because of biodegradable properties and low cost have been used as coagulants. In this study, chitosan as a natural coagulant of choice, was modified by (3-chloro 2-hydroxypropyl)trimethylammonium chloride and was used to remove the color and turbidity of industrial wastewater. To evaluate the effect of pH, settling time, the initial turbidity of wastewater, the amount of coagulant, and the concentration of dye (Melanoidin) were chosen to study their effects on removal of wastewater color and turbidity. The experiments were done in a batch system by using a jar test. To achieve the optimum conditions for the removal of color and turbidity, the response surface methodology (RSM) experimental design method was used. The results obtained from experiments showed that the optimum conditions for the removal of color were as: pH = 3, concentration of dye = 1000 mg/L, settling time = 78.93 min, and dose of coagulant = 3 g/L. The maximum color removal in these conditions was predicted 82.78% by the RSM model. The optimal conditions for the removal of turbidity of the waste water were as: pH = 5.66, initial turbidity = 60 NTU, settling time = 105 min, and amount of coagulant = 3 g/L. The maximum turbidity removal in these circumstances was predicted 94.19% by the model. The experimental results obtained in optimum conditions for removal of color and turbidity were 76.20% and 90.14%, respectively, indicating the high accuracy of the prediction model.

Use of the extract of the flower of Musa sp., in the treatment from coagulation – Flocculation, of iron ore fines

Tannins condensed and hydrolyzable, extracted from the flower of Musa sp. was used in the process of reducing turbidity of effluents from the processing of iron ore. A great deal of attention has been given to coagulation and flocculation processes in the separation of the ore fines that remain adhered to silica after processing, aiming at the reuse of process water and the iron itself with percentages between 15 and 35%. The coagulation and flocculation tests were performed in a jar test, verifying the influence of the factors: pH, coagulant volume and frequency of agitation aiming at turbidity reduction. Response surface methodology was used to construct a model and verify the influence of the levels of each of the factors on the turbidity reduction. From the constructed model, it was possible to optimize the turbidity removal through the generalized reduced gradient algorithm (GRG) leading to an initial turbidity reduction of 86500 NTU in 97.58%.

Possibility of utilizing natural coagulants (Trigonella foenum-graecum and Astragalus gossypinus) along with alum for the removal of turbidity

Water, especially drinking water, might need to be treated before being utilized. Coagulants play a significant role in water treatment. In spite of having adverse effects on human health, aluminum sulfate, alum and other chemical coagulants are commonly used in coagulation processes. Utilization of natural and herbal materials such as quince seeds, fleawort, tragacanth, starch and yeast as coagulant aids has been experimentally investigated in this study. The aims of the present paper are: (1) to determine the optimal dose of Trigonella foenum-graecum (fenugreek) and Astragalus gossypinus (tragacanth) seeds as coagulant aids along with alum for the coagulation of raw water from Minab water treatment plant) located 7 km away from Bandar Abbas–Minab road at the east of Bandar Abbas in Iran, with a total area of 11.5 ha) and (2) to study their influence on reducing the water turbidity at a pilot scale. According to the obtained results, the optimum amount of alum (without additives) was calculated as 35 mg/L for water with the initial turbidity of 70–75 NTU, as the average turbidity interval. Using A. gossypinus and T. foenum-graecum seeds as coagulant aids, the optimum amount of alum reached 22 mg/L. The performance of A. gossypinus, as a coagulant aid, was much better in low concentrations. It was used in doses of 0.25, 1 and 2 mg/L along with 20, 22 and 28 mg/L of alum for low, intermediate and high turbidity levels (28, 70 and 120 NTU) and led to turbidity removal percentages of 85, 94.5 and 96.4, respectively. The optimum amounts of T. foenum-graecum seeds for the three mentioned turbidity levels were calculated as 1, 2 and 4 mg/L. The turbidity removal percentages of 91.5, 95.7 and 97.8 were obtained using the mentioned amounts of T. foenum-graecum seeds along with 20, 22 and 25 mg/L of alum, respectively. Similar results were obtained by using both additives along with alum.

Efficiency of Chitosan as a Coagulant for Wastewater from Slaughterhouses

Objective:The purpose of this work was to obtain chitosan from shrimpexoskeletons, characterize it and evaluate its coagulant activity in the turbidity removal of wastewater from slaughtering Units. Methods/Analysis: Wastewater samples had three different turbidity measures(250, 560 and 863 NTU) and with three different doses of coagulant each (50, 100 and 150 mgL-1), according to a 32experimental design. Control and ANOVA tables were used to verify if there were statistically significant differences among data with a 95% confidence level. Findings: Chitosan with a molecular weight of 3.2x106 g mol-1 and a degree of deacetylation of 74% was obtained. When used as a coagulant it is possible to obtain turbidity removals greater than 90% when initial turbidity of wastewater was equal to or greater than 560 NTU. However, and due to acid nature of coagulant extracts, pH and alkalinity of samples were influenced. Effectiveness of chitosan in wastewater treatment with high organic load and difficult treatment was verified. Application: In conclusion, it is possible to obtain excellent quality chitosan from shrimp exoskeletons and its use is convenientin alkaline wastewater.

Removal of Turbidity from Travertine Processing Wastewaters by Coagulants, Flocculants and Natural Materials

The sedimentation behaviour of travertine-processing wastewater containing a high concentration of suspended solids was investigated using different coagulation and flocculation methods. In batch experiments, four types of coagulants [FeC13, Al2(SO4)3, PACl, NaAlO2], six types of flocculants (40% MMW–40% HMW cationic, 30% MMW, 40% MMW, 40% HMW anionic and nonionic) and three types of natural materials (NMs) (sepiolite, zeolite, and pumice) were used to treat wastewater with an initial turbidity of 570–880 NTU. The optimum process conditions (dosage, mixing time/speed, sedimentation time, and pH) were investigated for each. Sedimentation performance was assessed by the effluent turbidity (T eff) values of the treated water. The best performances obtained were 99.3% (T eff = 4 NTU), 99.1% (T eff = 8 NTU), and 97.8% (T eff = 18 NTU) with 40% HMW anionic-cationic flocculants, zeolite, and FeCl3, respectively. Sludge properties, including sludge settling velocity (mm/min), sludge density (g/cm3), suspended solids (SS) content (mg/L), and sludge solids (%) were determined and compared under optimized conditions. The type of additive significantly affected performance. Travertine processing wastewater flocculation with polymeric materials and NMs, especially zeolite, was more favourable than coagulants in terms of both turbidity removal and sludge quality. Since zeolite is a NM, additional studies on using and recycling of the generated sludge as an industrial feedstock would be worthwhile.

Efficiency Comparison of PolyDADMAC Coagulant with Ferric Chloride in the Treatment of Ahvaz Drinking Water

Background& Objective: PolyDADMAC is used in water and waste water treatment as a primary organic coagulant which can neutralize colloidal material with negative charge and reduces sludge volume compared with Mineral coagulants. The aim of this study was to evaluate and compare of PolyDADMAC with ferric chloride as a coagulant on the removal of turbidity, Coliform and Organic matter from Ahvaz drinking water. Materials and Methods: This study was carried out in a lab scale and using a jartest device in Ahwaz water treatment. In this research, the coagulation of raw water was studied using PolyDADMAC alone, and mixed coagulant of PolyDADMAC and ferric chloride at various dose and ferric chloride alone were compared. The study range was selected for turbidity (NTU3850, 80), pH (9-5) and different concentrations of coagulant material .Data analysis was performed using Excel, SPSS software and one way ANOVA (p<0.05). Results: The optimal efficiency conditions of PolyDADMAC in turbidity 3850 NTU, pH=8, Flash Mix =120rpm and resulted in an optimum dose of 0.5 mg/L which the highest turbidity removal percentage was to be 99.84 in optimal dose of 0.5ppm of coagulant. The optimum doses of ferric chloride with PolyDADMAC were obtained at 15mg/L and 0/4mg/L, respectively. Under higher doses of PolyDADMAC, flocs showed stabilized in solution .In addition, PolyDADMAC also produced larger floc with higher settling velocity that need less time to settle. Conclusion: The results from the comparison of the effect of coagulants mentioned in the high turbidity removal (NTU 3850) indicate the good performance of PolyDADMAC as coagulant to ferric chloride Also, the results showed that the removal efficiency was affected by the initial turbidity so that the higher the initial turbidity, nwould be the more efficient the turbidity removal.

Performance of Natural Coagulant Extracted from Plantago ovata Seed for the Treatment of Turbid Water

Present study investigates the coagulation ability of Plantago ovata (P. ovata) seed extracts for turbidity removal. The active coagulant agents were successfully extracted from P. ovata seeds using different solvents such as distilled water (PO-DW), tap water (PO-TW), NaCl (PO-NaCl), and ammonium acetate (PO-AA). Experiments were conducted in batch mode for initial turbidity such as 500 NTU (high), 150 NTU (medium), and 50 NTU (low). Results demonstrated that P. ovata extracts are less efficient in low turbidities, while PO-NaCl was found to provide high coagulation activity in all initial turbidity concentrations compared to other extracts. PO-NaCl was able to remove 98.2, 94.9, and 80.2% of turbidity from water having in initial turbidities of 500, 150, and 50 NTU, respectively. Coagulation activity of the extract was the best when the extraction was performed for 50 min at room temperature. Jar test procedure with the coagulation time of 1 min and flocculation time of 30 min was optimized, irrespective of the initial turbidity. The optimum settling time for 500, 150, and 50 NTU water samples were 20, 30, and 90 min, respectively. PO-NaCl was used in different pH turbid solutions and it was found to be working very efficiently in alkaline conditions. The coagulation efficiency of the coagulant stored in refrigerator was higher than that stored at room temperature. Thus, the natural coagulants extracted from P. ovata seeds revealed to be effective for turbidity removal.

Dewatering Oil Sands Tailings with Degradable Polymer Flocculants.

We synthesized hydrolytically degradable cationic polymers by micellar radical polymerization of a short-chain polyester macromonomer, polycaprolactone choline iodide ester methacrylate (PCL2ChMA) with two polyester units, and used them to flocculate oil sands mature fine tailings (MFT). We evaluated the flocculation performance of the homopolymer and copolymers with 30 mol % acrylamide (AM) by measuring initial settling rate (ISR), supernatant turbidity, and capillary suction time (CST) of the sediments. Flocculants made with trimethylaminoethyl methacrylate chloride (TMAEMC), the monomer corresponding to PCLnChMA with n = 0, have improved performance over poly(PCL2ChMA) at equivalent loadings due to their higher charge density per gram of polymer. However, MFT sediments flocculated using the PCL2ChMA-based polymers are easier to dewater (up to an 85% reduction in CST) after accelerated hydrolytic degradation of the polyester side chains. This study demonstrates the potential of designing cationic polymers that effectively flocculate oil sands tailings ponds, and also further dewater the resulting solids through polymer degradation.

Treatment of phenol in petrochemical wastewater considering turbidity factor by backlight cascade photocatalytic reactor

Abstract The toxicity of phenol is such that even in its low concentration in industrial wastewater, it should be removed. Photocatalytic treatment is an appropriate method for treating toxic and difficult to biodegrade organic materials. However, most phenol containing wastewaters such as petrochemical wastewater, contain turbidity that limits photocatalytic treatment usage. To remove phenol from petrochemical wastewater, a novel cascade photocatalytic backlight reactor is developed. In the developed reactor, the effect of four factors including initial phenol concentration, TiO2 concentration, turbidity, and pH on phenol removal efficiency is investigated using full factorial design. The best removal efficiency was 88% obtained after three hours when pH is 9, initial phenol concentration equals 50 mg/L, and TiO2 concentration equals 80 g/m2. The relationship of these parameters on phenol removal efficiency is statistically evaluated using analysis of variance. The significance of reaction parameters is shown as follows: time > initial phenol concentration > TiO2 concentration > pH. The ANOVA analysis also reveals that turbidity has no effect on phenol removal efficiency.

Study on natural soil coagulants for point-of-use drinking water treatment

Natural soil coagulants were used for domestic drinking water treatment in Ethiopia because of lacking drinking water supply. In this study, two soils were collected from Ethiopia and jar test was used to investigate the optimum working conditions, performance and safety of them. The turbidity removal efficiencies of soil A and soil B are 74.5% and 91.1% (initial turbidity=400 NTU), respectively. The pH of purified water can meet drinking water standards of Ethiopia (pH=6.5-8.5). Both soils contribute to remove TOC when the initial concentration of it is high. A small amount (0.5 mg. L-1 or 1 mg. L-1) of poly-aluminum chloride can improve the performance of soil coagulants for the removal of turbidity. The application of soil coagulants didn’t introduce coliforms, although the total bacteria number of treated water increased to 40 CFU (soil A) and 81 CFU (soil B), still meeting the drinking water quality standards (<=100 CFU).

A comparison of different pilot constructed clarifiers with the purpose of achieving the optimum condition in turbidity removal at water treatment plants in Tehran

Clarifying is one of the most crucial stages in water treatment at water treatment plants. Determining the type of the clarifier in water treatment plants and using it efficiently is necessary. In this study, a pilot is designed and constructed in which the pulsator, the superpulsator and the accelerator are simulated. For each system, turbidity removal efficiency for different influent turbidities and flow rates were studied and the optimum condition was obtained. The results showed that the superpulsator has a superior performance compared to the pulsator, and the pulsator has a superior performance compared to the accelerator and these differences are more sensible at higher flow rates. Also, the best condition for achieving the highest efficiency for the pulsator and the superpulsator is determined to be at flow rate 3 lit/min for an initial turbidity of 2,500 NTU with alum as the coagulant and the highest efficiency for the accelerator is determined to be at flow rate 3 lit/min for an initial turbidity of 2,500 NTU with ferric chloride as the coagulant. Comparing the turbidity removal efficiency shows that for 67% of the cases, ferric chloride has a better performance as the coagulant compared to alum and increasing the influent turbidity leads to an increase in the removal efficiency. Furthermore, three water treatment plants located in Tehran were studied and their characteristics were compared and suggestions were made to enhance their qualities.

The Effectiveness of Moringa oleifera Seed Flour and Chitosan as Coagulant‐Flocculants for Water Treatment

The aim of this contribution is to provide a comprehensive comparison between chitosan and Moringa oleifera seed flour (MOSF) as coagulant‐flocculants. MOSF was obtained as a byproduct in a biodiesel process. Turbidity and heavy metal ion removal, using both eco‐friendly materials, was assessed. Jar tests were performed on samples taken from river water, agricultural wastewater, and mixed wastewater (contaminated with agricultural and urban residues). Bioflocculant dosages within the range of 0.005–20 mg L−1 were tested. Irrespective of the initial turbidity, the optimal dosage of chitosan and MOSF for decreasing turbidity in river water was 1 and 5 mg L−1, respectively. Furthermore, from river water, Pb removal up to 95% was achieved irrespective of the bioflocculant; for Mn removal, MOSF performed better than chitosan, with the adsorbent trapping close to 90% of this metal. MOSF decreased turbidity levels and heavy metal content (Mn and Pb) to under the permissible limits (Mexican environmental regulation for potable water, NOM‐127‐SSA1‐1994). Additionally, kinetic data were fitted to kinetic models of adsorption for the pollutants. For agricultural wastewater, a chitosan dosage of 10 mg L−1 reduced turbidity to 5–10 nephelometric turbidity units (NTU), and a MOSF dosage of 10 mg L−1 decreased the turbidity to values lower than 5 NTU. For the mixed wastewater, chitosan achieved a high turbidity removal, while MOSF was not suitable.

Phytoremediation Capabilities of Spirodela polyrhiza and Salvinia molesta in Fish Farm Wastewater: A Preliminary Study

Fish farm wastewater needs to be treated as it contains considerably high loading of suspended solids and dissolved nutrients from accumulation of by-products e.g. fish excretions and uneaten feed. In this study, macrophytes, namely Spirodela polyrhiza and Salvinia molesta were examined for their phytoremediation efficiency in treating fish farm wastewater in a raceway pond rig. It was carried out indoor for 14 days under controlled environment. Water samples was collected once every 2 days for analysis of NO3-- N, PO43-, NH3-N, COD, turbidity, MLVSS and pH. The results showed that there was decrement of phosphate in fish farm wastewater using either S. polyrhiza or S. molesta. Interestingly, S. polyrhiza was found to be more efficient in phosphate uptake as it removed 72% phosphate at day 4 and up to 95% in the end of the experiment whereas 72% phosphate removal was only achieved by S. molesta at day 10. Similar ammonia decrement was observed for both plants and most of the ammonia were not detected in the wastewater by day 10 for S. polyrhiza, while by day 8 for S. molesta. Nitrate showed increment for both plants which could be due to nitrification. Both plants achieved highest COD removal on day 12, whereby 68% for S. polyrhiza and 63% for S. molesta. They were able to reduce turbidity and total suspended solids (TSS) to very low level and significantly increase clarity of wastewater. S. polyrhiza reduced up to 96% of initial turbidity value and 86% of TSS. 82% reduction of initial turbidity and 79% TSS decrement were observed for S. molesta. pH fluctuations were minimum for both plants, with a range between 7.62 to 7.77. Both plants demonstrated biomass increment for fresh weight in which 84% for S. polyrhiza while 85% for S. molesta. This study proved that the macrophytes were able to treat fish farm wastewater by significantly removing phosphate, ammonia, turbidity and TSS. It aids in minimizing pollutants released to receiving waters and producing biomass which can be utilized for agriculture sector.

Cb jKSD&gt;CMlds

Few papers were well discussed about whether the variation of organic property and initial turbidity could affect its removal by coagulation. In this study, EEFMs(Excitation Emission Fluorescent matrix) of DOM (Dissolved organic matter) by parallel factor analysis (PARAFAC) was applied to elucidate the variation of organic matter in both source waters of FS and CCL water treatments. Meanwhile, the molecular weight cut-offs was measured by HPLC equipped with Diode Array Detector (DAD) containing of HPSEC column. Current finding reveals that both source waters containing of four major fluorescent components were varied with the change of seasons. MWCOs were also affected by the change of low flow and flooding season. The optimal alum dosage was simultaneously affected by the initial turbidity as well as organic characteristic. Interestingly, the aggregation of lower or higher MWCOs was found in high alum dosage added.

A TURBIDITY REMOVAL STRATEGY FROM THE WATER RESOURCES OF BANDUNG CITY, INDONESIA

Cikapundung and Cisangkuy River are the sources of raw water used by Bandung City. The special characteristics of these water resources are the fluctuations of flow and turbidity in the dry season and the rainy season with the highest turbidity > 600 NTU. The turbidity fluctuation is not significantly followed by the coagulant dose changes. This research was conducted in order to evaluate and strategize the optimal performance of the water treatment plant based on the evaluation of the processed water. The laboratory analysis was carried out to find the dominant parameters, namely turbidity, with the steps such as 1) comparing the coagulation process that has been or has not been through preliminary sedimentation using coagulant polyaluminium Chloride (PAC); 2) observing the stability and efficiency of sediment that resulted by coagulation process for the several variation of time; 3) analyzing the efficiency of the preliminary sedimentation and coagulation process. The results of laboratory analysis show that the optimum time of the deposition processes is 35 minutes with a decrease in turbidity of about > 80%. The highest efficiency of sedimentation processes occur at the initial turbidity of 514 NTU in the amount of 85.02%. The optimum coagulant dosage without using the preliminary sedimentation is reached at initial turbidity of 147 NTU with an efficiency of 99.76%; while those using the preliminary sedimentation are achieved at initial turbidity of 514 NTU with an efficiency of 99.46%. Based on these analyses, it is necessary to adjust the operational process of preliminary sedimentation.

Carwash wastewater treatment by micro and ultrafiltration membranes: Effects of geometry, pore size, pressure difference and feed flow rate in transport properties

Micro and ultrafiltration hydrophilic membranes were investigated for carwash wastewater reclamation. The effects of geometry as well as operating conditions such as pressure difference across the membrane and feed flow rate were investigated aiming the characterization of permeate flux and quality and evaluation of water reuse. The effluent showed initial turbidity of 85 NTU, in addition to total organic and inorganic carbon of 4.1 and 58mg/L, respectively. Tests in flat cellulose commercial membranes revealed that both micro and ultrafiltration showed good retention of solids and organic matter, as shown by turbidity and chemical oxygen demand. In order to increase the productivity, commercial hollow fiber polyetherimide membranes were investigated. The initial flux was 440L/m2h, with pressure difference of 0.4bar and Reynolds number of 400. The final permeate with recovery rate of 80% showed a total organic and inorganic carbon of 2.7 and 35.4mg/L, respectively. The rejection was 98.6%. The results showed that this approach has high potential to be used for water reuse depending of the number of cycles or recycling ratio is aimed.

Coagulation efficiency of &lt;i&gt;Dicerocaryum eriocarpum&lt;/i&gt; (DE) plant

A study was conducted to investigate coagulation efficiency of the plant Dicerocaryum eriocarpum (DE) in the removal of turbidity from raw water. Widespread poor land use practices contribute to high turbidity in river water, making turbidity management or removal critical, particularly before the water is used for drinking or subjected to chemical treatment. In this study, mucilage from DE was extracted with deionized water and different chloride solutions. A coagulation efficiency of 99% using modified mucilage coagulant was achieved. The modified mucilage of potassium crude extract and sodium crude extract displayed higher coagulation efficiencies than unmodified mucilage of deionized water crude extract. An increase in coagulant dosage and initial turbidity influenced the coagulation efficiency of DE coagulant. A large reduction in turbidity levels of the treated water samples resulted in an improvement in water quality. Keywords : coagulation, Dicerocaryum eriocarpum plant, mucilage, optimise, turbidity

Dewatering Oil Sands Mature Fine Tailings (MFTs) with Poly(acrylamide-co-diallyldimethylammonium chloride): Effect of Average Molecular Weight and Copolymer Composition

Copolymers of acrylamide and cationic comonomers such as diallyldimethylammonium chloride can effectively dewater solid suspensions containing negatively charged fine particles. A good example of such suspensions is oil sands mature fine tailings (MFTs). However, little is known about the impact of the microstructure of copolymers in dewatering performance. In this study, we used a surface response methodology to systematically assess the impact of chemical composition and average molecular weight of poly(acrylamide-co-diallyldimethylammonium chloride) in dewatering MFTs. We controlled the chemical composition and average molecular weight of the copolymers by manipulating feed monomer/comonomer ratios and initiator concentration. We found both the copolymer composition and the molecular weight averages were statistically significant variables for initial settling rates and supernatant turbidities of flocculated MFTs. However, capillary suction time and resistance to filtration depended only on copolymer c...

Process Modelling and Simulation of a Simple Water Treatment Plant

Water treatment plants are likely to experience problems such as the water level both in the filter cells and in the tanks tend to fluctuate widely. These create the potential for partial drainage, overflow, and potential initial turbidity breakthrough at the beginning of the filtration cycles. This paper presents a mathematical model for studying the process behavior of a water treatment plant. A state equation was developed as a mathematical model of the process. This mathematical model was used to simulate the effects of varying the parameters of the plant (R, C, and I) representing the restriction of the connecting pipes, the capacity of the tanks and the filteration of the water filter, respectively, on the state variables (height of tank, h, and flowrate, q). The results of the simulation are presented graphically in the study. From the analyses, it was observed that varying any of the values of the parameters of the model has an effect on the water levels in the various tanks and the flow of water through the filter. The analyses of this paper on modeling a water treatment plant is a very simple way of knowing from the beginning the various sizes of pipes, tanks and filter to be used and how these will affect the flow of water in the plant before going into the physical construction of the plant.

Removal of turbidity from washing machine discharge using Strychnos potatorum seeds: Parameter optimization and mechanism prediction

In this research an attempt has been made to utilize the Strychnos potatorum seed powder as an environmentally friendly coagulant for theremoval of turbidity from washing machine discharge. The performance of this system was also compared with synthetic water. Experimentalstudies were conducted for the maximum removal of turbidity from washing machine discharge and synthetic turbid water which were varied from50 to 145 NTU. The effect of operating parameters such as initial turbidity, S. potatorum dosage and pH of the solution was optimized for themaximum removal of turbidity. It was seen that the percentage removal of turbidity lay was between 68–89% and 65–84% for synthetic turbid waterand washing machine discharge sample respectively, at an ideal pH of 6–7. The experimental values were compared with the Langmuir andFreundlich isotherm models to understand the extent of influence of the sorption of the particles onto the S. potatorum seed powder. Better resultswith respect to concordance of experimental data were observed with Langmuir isotherm model, indicating a monolayer sorption of particles ontothe S. potatorum seed powder. It was observed from the isotherm study that the sorption may also be influenced in the removal of turbidity to someextent from the washing machine discharge and synthetic water. The prepared material can be effectively utilized for the removal of turbidity fromthe water.
