Purification of borehole and domestic waters in rural conditions of Uzbekistan using filters and their hydraulic calculation

Abstract

One of the main factors of human life is water, because more than 70% of the human body is water. In a situation where there is a shortage of fresh water around the world, there are increasing problems waiting to be solved, such as protection of water resources, effective use, and prevention of changes in their physical and chemical conditions. Environmental pollution also affects groundwater. Direct consumption of groundwater also has negative effects on the body in many cases. This article develops recommendations for specific amounts of groundwater treatment. Experimental tests were carried out and hydraulic calculations were carried out for the use of gravel and quartz sand, which are local raw materials, as filter load. The retention of organic and inorganic substances in a certain amount when water is passed through the filter load has been proven in experiments, and the results of the conducted research are presented in the article.
