Founded in Telford U.K, DEWLINK SLUDGE TREATMENT LTD provides a simple and cost effective method of dewatering sludge and wastewater from many industrials. (�� (�� (�� (�� (�� (�� Finding a polymer to dewatering lime treated sludges with a high pH is a problem. The optimal polymer concentration for activation is often not dilute enough to be the optimal concentration at the injection point, so it is helpful to have an additional post-dilution stage after the make-down and/or aging stages. The type of polymer (dry, emulsion, or Mannich) will dictate the necessary systems and equipment for storage, handling, polymer solution make-down, and polymer solution injection. (�� (�� (�� (�� (�� (�� (�� (�� (�� The physical characteristics of the sludge can vary significantly, it is therefore essential that the dewatered sludge handling system selected has the .
