Abstract
Water contamination was a serious problem throughout the world. Various technologically advanced treatment methodologies for example activated sludge process, membrane bioreactor, trickling filter, rotating biological contractor and oxidation ditch are widely studied well documented and adopted in practice. However, attention to promising low-investment-cost technologies such as slow biological waste water treatments after preliminary/primary treatment techniques was quite effective water treatment technology. It is also efficient in removing coli form microorganisms such as Cryptosporidium, E. coli and bacteriophage from wastewater. Apart from reduction of pathogenic load which is ascribed to the biological processes. This way of technology adopted the methodology taking the sample in the field of water surface two parts in sampling pond water in the surface pond water and inner parts also handling two different glass bottles. Then in analysis their analysis the sample subjected to physiochemical analysis then again the sample subjected to serial dilution to identify the microbe’s spp in the water sample (surface and deepest) part of pond water surface part of sample more microbes familiar conducted in this experiment. Then by using those identified microbes dosing this is done using 10-6 and 10-5 by prepared nutrient agar (3.25 gram with 250 ml of distilled water). Then take 1% (0.5), 3% (1.5) and 5% (2.5) by volume of broth added into waste water of 49.5 ml, 48.5 ml and 47.5 ml respectively. This means that for 50 ml of conical flask as the colonies of culture increase the probability of waste water to be clear was too been high so 47.5 with 5% (2.5) combined form of broth high potent of cleaned.
Highlights
Waste water is any water that has been adversely affected in quality by anthropogenic influence
Wastewater can originate from a combination of domestic, industrial, commercial or agricultural activities. [16, 9] The socio political and industrial corner of Ethiopia, the capital city Wolkite for gurage zone SNNP regional state of Ethiopia generates high amount of wastewater from municipal and industry [13, 10]
The waste water from SNNPR regional state of Ethiopia guraga zone town of wolkite kara sefer specific area jeblow meda pond water was collected from surface & deep of pond, and was transferred to lab using two glass bottles for analysis
Summary
Waste water is any water that has been adversely affected in quality by anthropogenic influence. Wastewater can originate from a combination of domestic, industrial, commercial or agricultural activities. [16, 9] The socio political and industrial corner of Ethiopia, the capital city Wolkite for gurage zone SNNP regional state of Ethiopia generates high amount of wastewater from municipal and industry [13, 10]. Sewage is a type of wastewater that comprises domestic wastewater which is contaminated with urine from people's toilets and other sources such as, surfactants, personal care products and others, and can cause series problems to the community if not treated properly [13]. The seasonal and perennial rivers and groundwater reserves of Addis Ababa are polluted with different organic and inorganic pollutants by industrial and municipal solid and liquid wastes. There may be nitrate or other endocrine disrupting substances in this waste water that comes from toilet or other the sources. There may be nitrate or other endocrine disrupting substances in this waste water that comes from toilet or other the sources. [12, 15] Beyond the necessary limit of this compound is not well for plant even it can cause potential health hazards to infants and pregnant women or may be the cause for infertility [4, 6]
