Suction, discharge and reverse osmosis hoses for industrial water facilities

摘要

Many industries depend on water as a cleaning or cooling agent. However, those and other processes produce wastewater that contains impurities. Wastewater treatment allows the discharge of the water back into the ecosystem by removing impurities, solids and particulates. In most instances, the wastewater treatment process begins with pumping — or lift — stations that pump the raw wastewater to treatment plants. Removing impurities from the water occurs in stages that remove coarse and fine debris, reduce solids content, eliminate organic materials and filter any pollutants from the water. Some wastewater treatments use carefully metered doses of chlorine or sodium hypochlorite to eliminate any microorganisms in the water and then add sulfur dioxide or sodium metabisulfite to neutralize the chlorine. Other applications use ultraviolet light — rather than chlorine — to remove any other microorganisms.
