An increase in the volume of industrial effluents, ship accidents, oil breakthroughs at drilling rigs lead to a deterioration in the quality indicators of water in open water sources, including in terms of the content of organic compounds and oil products. The water used for irrigation of agricultural crops, according to most indicators, must meet the water quality requirements for household and drinking purposes. Thus, the total content of oil products in the irrigation water should not exceed 0.1 mg / l. The use of water with the MPC excess leads to significant changes in the morphological properties of the soil, reduces the biological productivity and phytomass of the plant cover. Therefore, the issue of improving machines and devices used in water treatment technologies to increase their reliability and efficiency is one of the topical areas of the research. The aim of the study is to develop a hydrocyclone complex cleaning apparatus, which implements combined processes of capturing both coarse and finely dispersed impurities. Unlike the standard design, the hydrocyclone is supplemented with a filter element installed on the drain pipe, which provides additional water purification from fine mechanical impurities, and a sorption filter designed to remove oil products and other floating organic compounds from water. The proposed hydrocyclone unit provides a comprehensive purification of irrigation water from various types of impurities, due to the combined processes of centrifugal separation and sorption filtration. It eliminates the multistage process of water purification, and regeneration of the sorption filter by the action of centrifugal forces or pressure does not require the use of special regenerating solutions, which increases the manufacturability and environmental friendliness of the water treatment process.

It is well-known that TiO2is an environmental benign photocatalyst which can be used to decompose harmful organic compounds. Recently, many studies are concentrated on the purification of industrial wastewater due to the requirement of environmental protection. In present study, TiO2nanomaterials supported by fine zeolite particles have been used as the photocatalyst to purify the oily wastewater. It has been found that the oil concentration in the modulated water can be reduced significantly and rapidly under the action of photocatalytic degradation and the ultraviolet light radiation. After 80 minutes, oil concentration in the modulated water can be reduced by more than 80%. The results suggest that TiO2nanomaterials supported by fine zeolite particles are effective material for purification of oily wastewater. In addition, the present results show that the efficiency of water purification can be significantly increased by use of mechanical stirring during the photocatalytic degradation process.

Application of solar energy to purify the water is advancing rapidly since it is an attractive alternative because of its simple technology; non-requirement of skilled labor for maintenance work, low energy consumption and no fuel is required for operating such water purification unit. This paper deals with the performance evaluation of the solar water purification at Mechanical Engineering Department MMMUT Gorakhpur, India. To perform this experiment, parabolic trough of fixed rim angle and length is considered. Based upon rim angle and length other pertinent parameters are calculated and selection of materials for fabrication of the unit is done. After that solar water purifier unit is fabricated. The solar parabolic collector utilizes the concentrating solar power technology to concentrate the solar insolation. The performance of parabolic trough is evaluated by considering the effect of glass cover on the concentrator. Various results are plotted between the temperature of the fluid and time keeping other parameters held fixed. Further a comparative study is performed for solar water purification unit with and without glass cover. The purity of water is measured based on its pH value and total dissolved solid (TDS).
