Inorganic Polymers & Coagulants

Our line of inorganic polymers and coagulants for water and wastewater treatment and the pulp and paper industry includes Aluminum-based Products, Enhanced Coagulants, Ferric Sulfate, etc. Our enhanced coagulant product line is one of the broadest in the United States. It encompasses over 25 liquid products, containing both Polyaluminum Hydroxychloride alone and in combination with organic polymers. Different coagulant grades work under different conditions to meet a range of treatment goals, from removing turbidity, color and TOC; to extending filter runs and reducing backwash waste; to decreasing sludge volumes and the use of pH adjustment chemicals. Our coagulants perform particularly well where conventional systems fail (e.g., with cold or low-alkalinity source waters) and often allow plants to reduce cost and extend operating range significantly.

The reactivity of any product in the polyaluminum chloride family depends on basicity, or the amount of [OH] present, generally expressed as % basicity (or [OH]/3AI X 100). Basicity ranges from below 10% to above 80%, which impacts the generation of cationic charge in the products.
