TECHNOLOGY FOR EXTRACTION OF NITROGEN AND PHOSPHORUS FROM WASTE WATER FORMED IN THE PROCESS OF WASTE WATER SEDIMENT TREATMENT

Description of the project: The proposed technology is intended for the extraction of nitrogen and phosphorus from sludge water formed in the treatment of sewage sludge and other waste water concentrated by these elements using semi-burnt dolomite.

Advantages: The proposed technology allows to reduce the supply of biogenic elements with return flows of sludge treatment to treatment facilities, as well as extract nitrogen and phosphorus for their subsequent use as a soil-improving additive in agriculture and forestry. The use of semi-fired will expand the scope of the Belarusian carbonate raw materials.
