Romania – Flocculating agents – AGENTI DE FLOCULARE (POLIELECTROLIT)

Procurement of flocculating agents to ensure optimal conditions for the operation of the compartments involved in the treatment of wastewater – thickening/dehydration processing of the sludge resulting from wastewater treatment. In wastewater treatment plants, domestic wastewater undergoes several stages of mechanical, biological, or chemical removal of suspensions, sand, toxic pollutants, fats, and is then separated by decantation from the resulting sludge. Excess sludge must be removed for bio-chemical processes to be efficiently controlled, with removal being achieved through stabilization and thickening/dehydration processing. The thickening/dehydration processing of wastewater treatment sludge is carried out by adding flocculating agents - polyelectrolytes that promote concentration and dehydration processes, acting on the solid particles in the sludge, by neutralizing their electrical charge and by forming flocs with improved dehydration properties.
