Phosphorus removal from wastewater with Liquiline ControlMany wastewater treatment plants use chemical phosphate precipitation to remove phosphorus from wastewater. However, phosphate loads can fluctuate, making optimal precipitant dosing difficult. If the dosage is too low, the strict phosphorus limits will not be met. In contrast, overdosing means a higher volume of sludge and thus higher disposal costs – in addition to wasting the costly precipitant. Furthermore, the salinity in the biology increases, leading to corrosion in the plant.
