IMPROVEMENT OF THE FILTER FIBER POLYMER MATERIALS FOR WATER WELLS
It is made the analysis of the materials used for the device filters water wells. It is marked the features of their work in the presence of gravel backfill and without it. It is examined the influence of various factors on the loss of pressure in the filter and the flow rate per well. It is shown the method for calculating the flow rate of wells taking into account the imperfect nature of wells by the character of baring with a surface water intake of fibrous polyethylene. It is the optimal duty cycle for filter diameter of 200 mm and 300 mm. The use of filters on wells of polyethylene fiber can reduce their costs and improve efficiency as compared to wells with wire filters made of stainless steel.
