Assembly for cleaning waste water, to provide clean water for industrial use, uses a rapid counter flow with two filters and controlled electromagnetic valves to set the flows

摘要

The assembly for cleaning waste water, with a rapid counter-current, has two filters (10,10a), two motors (40,41), a collection tank (42) for the cleaned water and a tank (43) for collected waste water. The upper water outflow from each filter is fitted with a flow meter (17,18) and a branch pipe. Electromagnetic valves (19C,20C1) are at both ends of the branch pipe. Branch pipes are connected together for the waste water to flow, with links to the motors to move the water through the filters, and from the filters to the clean water tank.
