Drewfloc™ flocculants
Chemically treating influent water that is used in industrial processes ensures a consistent and reliable supply of water that meets required quality standards. Likewise, the proper treatment of wastewater ensures that the water is suitable for discharge to natural waterways. The type of treatment employed depends on the water source, its chemical content and its intended use.
Ashland’s Drewfloc flocculants comprise a family of proprietary
products, including anionic, cationic and nonionic emulsions and dry polyacrylamides, which can be used whenever liquid/solids separation is required in industrial and municipal applications. To meet the demands of various treatment applications, such as clarification and sludge dewatering, Drewfloc products are available with different molecular weights and charge densities. Additionally, straight and branched polymer products are available for applications requiring enhanced performance.
