Floating synthetic filtering device development for turbidity value reduction of water in Eshkakon reservoir

This paper presents multifactorial studies to solve the improving water quality problem where effective filtering devices development is relevant. Intake filters perform primary treatment retain water suspension and debris of anthropogenic origin. Water analysis monitoring of the Eshkakon reservoir has been presented, as a result there is a need to use a filtration device to reduce its turbidity. A comparative analysis of material, construction and operating costs of various types of water intakes is given and the most economical and prospective one, composed of soft floating filtering devices made of synthetic fabrics, is identified. The main purpose of the device is to reduce “mud load”, mechanical pre-treatment of fresh water until entering a water treatment plant (WTP), water purification from plankton and suspended particles. The main element of the device is a filter wall made of flexible polypropylene material, which makes selective water intake. Advantages of the device include flexibility, high short-term and long-term strength, rot proofing; compliance of the filter design with effective fish protection devices; economic effect of advent of technology is to reduce investment in its manufacture, material consumption and labor costs in operational cycle
