FIELD: water treatment.
SUBSTANCE: invention is intended for water treatment. Self-flushed water hyperfilter has three chambers and includes upper, middle and lower chambers. Upper chamber is separated by a separating sieve pack, and the lower one is separated by a filter pack. First pipeline for supplying clarified water is connected to the middle chamber, the inlet of which is connected to the pipeline for supplying initial water to the consumer and is equipped with a valve and an electromagnetic valve. Pipeline equipped with three solenoid valves with common inlet is connected to the branch pipe of the lower chamber, and the second pipeline for discharge of clarified water, the first pipeline for supply of clarified water and the third pipeline for discharge of pre-washed effluent are connected to the outlets of the above electromagnetic valves. Ejector is connected to the branch pipe of the middle chamber, the central nozzle of which is connected to the fourth pipeline for inlet suspension, which is equipped with a valve and an electromagnetic valve, and the hole for microsand input is connected through the electromagnetic valve to the microsand hopper. Upper chamber branch pipes are connected to the fifth flushing water supply pipeline equipped with a valve and an electromagnetic valve, and the sixth flushing water discharge pipeline equipped with an electromagnetic valve. Pipelines of the second, fourth, fifth and sixth and middle filter chambers are equipped with branch pipes for water sampling for water flow and turbidity sensors, and the first pipeline is equipped with pressure, flow rate and turbidity sensors. Measuring outputs of sensors are connected to microprocessor control unit with provision of switching of valves and electromagnetic valves at transition from filtration mode to washing mode.
EFFECT: multiple increase of filter efficiency with provision of the specified degree of purification within range of 0.9–0.98.
