Solar Energy Based Sea Water Desalination Machine with RO and UV Purifier

Access to clean and potable water is a growing global concern, particularly in coastal and arid regions where freshwater sources are scarce. Traditional desalination tech- niques, such as thermal distillation and conventional reverse osmosis, rely heavily on fossil fuel-based energy sources, leading to high operational costs and significant environmental impacts, including greenhouse gas emissions. Additionally, these systems often require complex infrastructure, making them inaccessible to remote and off-grid communities. To address these challenges, this research presents a novel solar-powered desalination machine that integrates Reverse Osmosis (RO) and Ultraviolet (UV) purification technologies. The proposed system harnesses solar energy to power high-pressure pumps, eliminating dependency on non-renewable energy sources. The RO unit effectively removes dissolved salts and contaminants, while the UV purification stage ensures microbial disinfection, delivering high-quality drinking water. By utilizing renewable energy, the system significantly reduces operational costs and minimizes carbon emissions, mak- ing it an environmentally sustainable and economically viable solution. The impact of this research extends to enhancing water security in remote and disaster-prone areas, providing a decen- tralized, self-sustaining water purification solution. Experimental results demonstrate the system’s efficiency in reducing Total Dissolved Solids (TDS) to potable water standards, ensuring safe and reliable water supply. Future advancements will focus on optimizing energy utilization, improving membrane longevity, and integrating smart automation for real-time performance monitoring. This study contributes to the global effort of sustain- able desalination, paving the way for cleaner and more accessible water resources. Index Terms—Solar Energy, Seawater Desalination, Reverse Osmosis (RO), UV Purification, Water Scarcity, Renewable En- ergy Photovoltaic (PV) Systems, Membrane Technology.

ПІДВИЩЕННЯ ЗНОСОСТІЙКОСТІ ПАРИ ТЕРТЯ ПОРШЕНЬ-ЦИЛІНДР НАСОСУ АВТОМИЙКИ ВИСОКОГО ТИСКУ

The analysis of the operation of the high-pressure car wash and the axial piston pump included in its composition was performed. The pump body is usually made of any metal or alloy (for example, aluminum or stainless steel), and the pistons are made of specially hardened steel. Since such units have a short service life, the question of their motor resource is quite relevant. In professional car washes, pistons made of metal ceramics and heat-resistant composite polymer materials are promising. The choice of material for replacing the base material of the axial pump piston is justified. According to the complex of physical and mechanical indicators, aromatic polyamide Fenilon-C2 and aromatic polyamide PM-69 prevail over most industrial plastics. Parts made of aromatic polyamide and polyimide withstand loads close to those permissible for non-ferrous metals and alloys, and their wear resistance is higher than that of metals. This made it possible to recommend them for use as high-pressure car wash pump pistons. Increasing the wear resistance of composite polymer materials based on aromatic polyamide Fenylon C-2 and aromatic polyimide PM-69 was carried out as a result of their modification with graphite and non-woven powders. Laboratory studies of the wear resistance of antifriction materials of pistons of axial-piston hydraulic machines showed the feasibility of using materials based on aromatic polyamide PM-69 and aromatic polyamide Fenylon C-2 as pistons or cylinder liners. It was found that the material based on aromatic polyimide PM-69 (60 wt.%) and fluoroplast-4 (40 wt.%). Aromatic polyimide PM-69 has much less water absorption - 0.2-0.3 wt. % and this is its significant advantage over the aromatic polyamide Fenilon C-2. In addition, the aromatic polyamide PM-69 has significantly less water absorption, and this is its significant advantage over the aromatic polyamide Fenilon C-2.

Numerical simulation of single well geothermal system based on the artificial geyser concept considering phase change and multiphysics coupling

A geothermal system based on the artificial geyser concept can be free of high-pressure circulation pump. The core component of this system is a flash steam chamber located at the high-temperature well bottom, where periodic spray and vaporization of fine droplets occur, thus generating high pressure to drive the vapor to rise through the well- insulated inner tube of a coaxial heat exchanger (CHE). Though there was a semi-analytical model to evaluate this process, it failed to consider the heat transfer between ascending hot vapor and descending cold water in the CHE. Therefore, a new multi-physics coupled numerical model has been developed to assess the system operation mechanism, including the phase change of water. This model employs full coupling throughout its operation: during the downward flow of water in the well, it accounts for heat sources from both the hot formation and the ascending steam; during upward flow of vapor, it assesses the degree of steam condensation due to heat loss. The thermal behavior of descending water in the annulus is validated against existing research on a closed-loop borehole heat exchanger. Through the sensitivity analysis, it can be concluded that changes in the radius of production well and variation in the flow rate of injection well have a significant impact on the system's thermal power. For an engineering case with the same initial and boundary conditions, the outlet temperature of our system is around 50 °C higher than that of the hydrothermal system, and the total heat extraction reaches 380 kW, indicating that the artificial geyser system offers superior performance in terms of thermal energy utilization. After comprehensive optimization of the injection rate of water, the production well's radius, and the bottom pressure, the total heat extraction can reach 1 MW. In the actual project, one should monitor the pressure between the production well and the flash chamber to ensure the outlet vapor remains dry and has a high flow rate.

A novel nebulized drug delivery system based on an innovative high-pressure peristaltic pump availably applied to pressurized intraperitoneal aerosol chemotherapy.

Management of peritoneal carcinomatosis (PC) remains a significant clinical challenge due to a lack of effective therapies. Pressurized intraperitoneal aerosol chemotherapy (PIPAC) has been identified as a safe and efficacious treatment for PC. However, despite the observed high potential for PIPAC in treating numerous PC cases, the technology is still limited in China. To address this deficit, we developed a novel nebulized drug delivery system (NDDS) and evaluated it in this study. The NDDS was developed and was systematically assessed through tests of mechanical properties, granulometric analyses, sprayed distribution tests, and gravimetric analyses; moreover, drug penetration and distribution were examined in vitro and in a porcine model (female Tibetan pig). The NDDS, which included a high-pressure peristaltic pump, demonstrated a pressure initiation time of 5 s and a spray angle of 70°. Nebulization was consistent from the fifth second onward, with a median droplet diameter of 25.0-26.5 µm. The diameters of the sprayed intensive and expanded area were 26.1±1.4 and 48.5±1.0 cm at the vertical distance of 15 cm, and the stress generated was ≤3.790 Pa. Intraluminal drug distribution was extensive but heterogeneity, with 100- to 400-µm drug penetration depth (PD), and the optimal drug PD was observed in locations directly opposite to or adjacent surrounding the nozzle. The developed NDDS demonstrated promising mechanical properties, effective granulometric characteristics, extensive spray coverage, and satisfactory drug penetration and distribution. It offers a practicable solution for the application of PIPAC and will hopefully improve the current dilemma in PC therapy.

Coupled modelling and analysis of lubrication-wear evolution of textured piston/cylinder pair in high-pressure common rail pumps

Abstract Surface texturing is an important approach to enhance fluid lubrication performance and reduce friction and wear. Research on the surface texturing of the piston/cylinder pair considering various characteristics such as multi-physical fields and the evolution of friction and wear is still insufficient. The novelty of this work aims to establish a coupled numerical simulation model considering the coupling effect of multiple physical fields, wear of the cylinder bore and surface texture, and determine the effective surface texture parameters to improve the friction performance of the mechanical components of high-pressure common rail pump. The influence of surface texture on friction and wear characteristics and the evolution of lubrication-wear under different geometric cases were in-depth investigated, and the action mechanism of surface texture on lubrication and wear was revealed. Through numerical analysis, optimal parameters were identified that significantly reduce the friction coefficient and wear amount, offering practical insights for mitigating friction and wear in mechanical systems.

Analysis of Rail Pressure Stability in an Electronically Controlled High-Pressure Common Rail Fuel Injection System via GT-Suite Simulation

The high-pressure common rail (HPCR) injection system, a key technology for enhancing diesel engine performance, plays a decisive role in ensuring fuel injection precision and combustion efficiency through rail pressure stability. This study establishes a coupled simulation model of an electronically controlled HPCR injection system and a diesel engine, using GT-Suite to systematically investigate the effects of fuel supply pressure, camshaft speed, high-pressure pump plunger parameters, and inlet and outlet valve characteristics on rail pressure fluctuations. Gray relational analysis quantifies the correlation between these factors and rail pressure variations. The results demonstrate that increasing camshaft speed, injection pulse width, plunger mass, plunger length, plunger spring preload, inlet valve spring preload, and outlet valve body mass reduces rail pressure fluctuations, while variations in fuel supply pressure, plunger spring stiffness, and valve spring stiffness have minimal impact. Notably, the influence of outlet valve spring preload, inlet valve spring stiffness, and inlet valve body mass on rail pressure is nonlinear, with optimal values observed. Gray relational analysis further identifies inlet valve spring preload as having the highest correlation with rail pressure fluctuations (0.815), followed by inlet valve spring stiffness (0.625), with outlet valve spring preload (0.551) and stiffness (0.527) showing relatively lower correlations. This study provides valuable insights for optimizing the HPCR injection system design and contributes to advancements in diesel engine technology.

Safety design of the piston rod seal structure for submerged high-pressure liquid hydrogen pump

Abstract For the submerged high-pressure liquid hydrogen pump, a core piece of equipment of liquid hydrogen transportation, extensive analysis, and research were conducted on its components and structure during the development process. By referencing typical failure probabilities in the energy industry and statistical data from prototype pump development and testing, a list of failure probabilities for each part of the liquid hydrogen pump was compiled, and the consequences of those failures were deduced. The nitrogen liquid test experiment verified the possibility of pump seal failure and identified the fault modes. It confirmed that the piston rod seal is one of the critical components prone to failure in the liquid hydrogen pump. Subsequently, six important technical optimization measures for the piston rod seal pair have been carried out, reducing the probability of failure. Moreover, based on the concept of inherent safety, the sealing structure of the piston rod was innovatively designed, transforming hidden failures into visible ones, facilitating timely detection and monitoring of failures, and greatly reducing the safety risks caused by piston rod seal failure. The improved liquid hydrogen pump successfully passed subsequent tests, ensuring its long-term safe operation.

An integratible acoustic micropump based on the resonance of on-substrate sharp-edge micropillar arrays.

There is a growing demand for reliable, efficient, and easily integrated micropumps for microfluidics. Despite the demonstrated potential of acoustic wave-driven devices for on-chip pumping, current prototypes lack the practicality and integratability for deployment in microfluidic systems. This study presents an acoustic micropump based on the resonance of arrays of on-substrate sharp-edge micropillars prepared in a fluid-filled channel and driven by a piston ultrasonic transducer. At an operating frequency of 80.5 kHz and a driving voltage of 54 Vp-p, a flow rate of 16.2 μL min-1 is achieved in a downstream straight channel with dimensions 12(L) × 0.6(W) × 0.2(H) mm3. The corresponding pumping pressure exceeds 1.3 kPa, more than an order of magnitude higher than its predecessors. In experimental demonstrations, two micropumps are employed as feeding units for an acoustofluidic particle separation device based on tilted-angle standing surface acoustic waves (TaSSAWs). The current micropump exhibits advantages of high pumping pressure, fast response time, and high reliability, making it a promising pumping unit for lab-on-a-chip systems.

Onboard optical fuel sensing for enhanced combustion control in a multi-fuel compression-ignition engine

Compression-ignition (CI) engines with an ignition assistant can be made to operate on a wide range of fuels. The operation of such engines is most efficient and reliable if engine controls capable of real-time adjustments based on fuel cetane number (CN) are implemented. This study demonstrates a closed-loop engine control system using optical fuel sensing during fuel switches between two jet fuel blends with derived cetane numbers (DCN) of 45.80 and 32.79. Three fuel sensors utilizing Raman, dispersive near-infrared (NIR), and attenuated total reflectance Fourier-Transform Infrared (ATR-FTIR) spectroscopy were integrated in-line in a CI engine test cell to infer the DCN of the fuel upstream of the high-pressure common-rail pump. The engine control utilized the NIR sensor measurements to set CN estimation bounds. These bounds served as control inputs for regulating start of combustion (SOC) by adjusting start of injection and power delivered to an ignition assistant. All three fuel sensors provided accurate DCN estimates throughout the fuel switches, with errors of at most 6%, as validated by samples collected and tested using an Ignition Quality Tester (IQT). The engine control effectively utilized the fuel sensor measurements to maintain SOC within ±1 crank-angle degree of the desired value. Without the implemented system, misfires in engine operation are expected.

Investigation of Parameters Influencing the Establishment of Hydrostatic Mode in the Crosshead-Guide Assembly of High-Pressure Plunger Pump

Introduction. When applying hydraulic fracturing technology to increase the efficiency of formation fluids, high-pressure pumps with a crosshead drive assembly are used. The major problem in the operation of these pumps is the wear of the crosshead guides. The crosshead is a flat sliding friction pair, leading to wear of the plunger seals and a decrease in the basic pump performance indicators. To solve this problem, it was previously proposed to use new materials and antifriction coatings, original designs of friction units, etc. However, a detailed description and solution to the problem under consideration has not been found in the literature at present. The objective of this study is to determine, under maximum load, the influence of the unit design, process temperature and pressure in the lubrication system on the values of the parameters that provide for the hydrostatic mode for a flat thrust bearing in a crosshead-guide unit of a high-pressure plunger pump.Materials and Methods. The parameters were determined by the simulation technique using modal analysis applicable in the case of high dynamic loads acting on the studied unit. The calculation of the hydrodynamic parameters of the lubricating layer was based on the combination of the Reynolds model and the Stokes model in numerical modeling. The study was conducted using a calculation model representing a section of a plunger pump, considered as “flexible bodies” model, in the field of gravity forces. The mathematical dependences of the parameters under consideration were presented in the form of regression equations obtained from the results of a numerical experiment.Results. The maximum load on the lower crosshead guide was determined, for which further hydrodynamic studies were conducted. Factors influencing the process were studied — gaps filled with lubricant (depending on the design of the unit), temperature, and pressure in the lubrication system. Mathematical dependences of the influence of the considered factors on the values of the parameters determining the establishment of the hydrostatic mode were obtained.Discussion and Conclusion. The obtained mathematical models show the degree and influence of the factors under consideration on the studied parameters of the hydrostatic lubrication mode of the unit — the force acting on the crosshead from the lubricating layer, and the mass flow rate of the lubricant at the outlet of the system. It is found that the greatest influence is exerted by the change in the volume of gaps filled with lubricant, the mass flow rate of lubricant at the entrance to the system, which simulates the increase in pressure in the lubrication system of the friction unit. The results obtained do not contradict the conclusions reached in works on similar topics, and can be used in further research.

Distinguished by its rapid curing time and versatile applications, polyurea is applied using a spray gun with high-pressure pumps. The introduction of new building materials is part of ongoing efforts to meet stringent environmental, health, and performance standards, and polyurea offers significant improvements by eliminating solvents and volatile organic compounds (VOCs). This paper presents a technological protocol starting with inspection and cleaning, followed by drying, and ending with the application of three layers: a moisture-blocking base layer, a rigid polyurethane middle layer for structural reinforcement, and a final sealing and anti-corrosion layer. This innovative method ensures a homogeneous, seamless structure, enhances construction durability, and accelerates the repair process, allowing immediate resumption of operation. Designed specifically for aggressive wastewater environments, this system is characterized by excellent corrosion resistance, making it ideal for water and wastewater infrastructure elements such as reinforced concrete manholes, sewage pumping stations, and tanks. Customizable polyurea properties allow personalization based on environmental aggressiveness, structure size, and abrasion resistance, representing a significant advancement in infrastructure maintenance technology. The paper showcases this modern repair and renovation method, highlighting its applications, benefits, and potential to revolutionize water and wastewater infrastructure maintenance in challenging conditions. The effectiveness of this solution is also compared with traditional methods, demonstrating the superiority of the three-layer system in terms of waterproofing, sulfuric acid resistance, monolithic structure, and application time.

INNOVATIVE COOLING SYSTEM: SOLAR-POWERED WATER SPRAYERS FOR CATTLE SHEDS IN TULUNGAGUNG REGENCY

The Community Service (CS) project was implemented in Sumberingin Kidul Village, Ngunut District, Tulungagung Regency, East Java. The target beneficiary was UD. Arta Lumintu, a local SME engaged in beef cattle farming. The farm, established in 2017, was temporarily closed due to the Covid pandemic and resumed operation after a year. Key challenges included high temperatures (24-31°C) and humidity (74-77%), which negatively impacted cattle productivity and excessive electricity consumption for cattle shed operations. The project aimed to address these issues by installing a water spray system with a high-pressure pump and an off-grid solar power system. The system effectively reduces temperature and humidity in the sheds while minimizing electricity costs. The installation consists of a 540 Wp solar panel, a 1500 VA Smart inverter, a 100 Ah VRLA battery, and six pressurized water sprinkler points positioned in various areas of the cattle sheds, powered by a 350 W booster pump. This initiative improves farm efficiency, supports energy independence, and introduces smart farming technology to benefit local farmers.

In Situ Remediation of Combined Ammonia and Nitrate Nitrogen Contamination Using Zero-Valent Iron-Enhanced Microorganisms in Acidic Groundwater: A Laboratory and Pilot-Scale Study

In acidic groundwater, effectively removing both ammonia nitrogen (NH4+-N) and nitrate nitrogen (NO3−-N) poses a challenge. This study focused on studying the removal of NH4+-N and NO3−-N combined contaminations by zero-valent iron (ZVI) combined with microbial agents in both laboratory and field pilot-scale studies. Laboratory experiments showed that ZVI could reduce the denitrification stage from 15 days to 10 days by increasing solution pH and improving NO3−-N reduction efficiency. In a field pilot test (at Qingyuan, Guangdong Province, China), high-pressure injection pumps were used to inject alkaline reagents to raise the pH to 7~8. Meanwhile, compressors were applied to aerate the groundwater to increase the dissolved oxygen (DO) concentration above 2 mg·L−1. Subsequently, microbial agents of nitrobacteria were injected to initiate aerobic nitrification. As the DO level dropped below 2 mg·L−1, agents of micro-ZVI and denitrifying bacteria were injected to stimulate autotrophic denitrification. Intermittent aeration was employed to modify the redox conditions in the groundwater to gradually eliminate NH4+-N and NO3−-N. However, due to the effect of the low-permeability layers, adjustments in the frequency of remediation agent injection and aeration were necessary to achieve removal efficiencies exceeding 80% for both NH4+-N and NO3−-N. This work aims to overcome the limitations of microbial remediation methods in the laboratory and the field and advance nitrogen pollution remediation technologies in groundwater.
