  • What is praestol 2500 polymer?
  • PraestolTM 2500 polymer is a nonionic dry polyacrylamide that is used as a flocculant or coagulant aid in a wide variety of industrial, pulp and paper, mining and municipal wastewater treatment systems.
  • What is praestol 2500 used for?
  • Praestol 2500 is usually added as a dilute solution after the addition of cationic coagulants to promote larger floc, faster settling and denser sludge blankets with less pinfloc and carryover in the effluent water. It can often be used alone on high solids, aqueous, inorganic slurries such as clay, coal, pigments and metal hydroxides.
  • What materials can be used for praestol 2500?
  • For solutions of Praestol 2500, cross-linked polyethylene, fiberglass, stainless steel or epoxy lined steel are the preferred materials of construction for mixing and day tanks. Unlined mild steel, black iron, galvanized steel, aluminum, magnesium, copper or brass are not recommended in any part of the feed system.
  • How long does praestol 2500 last?
  • In dewatering applications, Praestol 2500 yields large and strong flocs that exhibit rapid separation of free water and produces sludge cakes with high solids content. Suggested in-plant storage is 2 years in unopened bags and rotation of stock is highly recommended.
