Split 130

Synthetic medium molecular weight cationic coagulant supplied as a convenient-to- use liquid. It is used for emulsion breaking, coagulation or flocculation of suspended solids and sludge conditioning in process and wastewater streams. Split 130 may also provide a cost benefit when fed with primary coagulants such as alum, ferric chloride, etc, by reducing the inorganic feed amount and sludge produced. Waters treated with Split 130 tend to form more stable, easily flocculated solids which often result in reduced sludge volume. Some of the processes in which Split 130 is used include; Flotation, Waste Dewatering, Oil/Water Separation, Turbid Water Clarification, Industrial Waste Clarification.
