Wastewater

Most of the water that is used in households or industrial enterprises becomes wastewater. To protect the nature from pollution, suspended solids, organic matter, as well as nitrogen and phosphorus must be removed from wastewater. If it is discharged untreated, the living conditions of water organisms deteriorate. Suspended solids reduce the transparency of water, and, when settled, cause silting of water bodies. Breaking down of organic substances diminishes the oxygen content of water, and the nutrients nitrogen and phosphorus promote eutrophication of waters.
