The experience of introducing the technology of chemical precipitation of phosphorus: from laboratory tests to industrial-scale operation

Summary

Meeting the latest recommendations of the Helsinki Baltic Marine Environment Protection Commission (HELCOM) calls for the introduction of advanced efficient methods of nutrients removal (mainly phosphorus) from municipal and industrial wastewater. Ferix-3 coagulant was chosen as a chemical. Industrial tests of chemical precipitation of phosphorus at the Kolpino, Kronstadt, Metallstroy settlement wastewater treatment facilities, as well as at the Central wastewater treatment plant, South-West wastewater treatment facilities and North wastewater treatment plant of St.-Petersburg are discussed. Chemical injection points and dosages for additional chemical dephosphorization were chosen depending on the treatment technology, automation level, wastewater composition, stability and irregular incoming flow rate.

Winery wastewater treatment

Summary

The efficiency of an integrated approach to the treatment of winery wastewater that is household and industrial wastewater, is estimated. A process flow scheme for winery wastewater treatment is proposed. The implemented technical solutions using the basic equipment of home manufacture provide for the sustainable wastewater treatment up to the maximum permissible concentrations of pollutants allowed for the discharge into fishery water bodies. The effluent can also be used in the business’s activities. The basic equipment is manufactured by Polikhim SPE of polymer materials (low pressure polyethylene, polypropylene, fiberglass), which guarantees a long service life of the entire complex of the treatment facilities.
