Contaminant removal system for water distribution network

摘要

PURPOSE:To provide an impurities-removing system in a network of water distribution pipes wherein impurities are prevented from being introduced in a specified region with pipe terminals by arranging an impurities-removing apparatus utilizing ingeniously flows in both directions and even if the impurities are generated in this region, the impurities can be caught and removed in a specified time. CONSTITUTION:In a closed water-supplying region connected with a running water pipe 7 only at two parts, since all the water flows therein through impurities removing apparatuses 10 and 10 of both directions type, there exists no possibility that outside impurities flow in this region. In addition, since water in a closed water-supplying region flows out wholly from this region through the impurities-removing apparatuses 10 and 10 of both directions type, even if impurities are generated in the region, there exists no possibility that they flow out and the impurities can effectively be removed by repeating normal flow and back flow.
