Coagulants and Flocculants for Water Treatment
Reduce sludge volume and improve water quality
Coagulation and flocculation water treatment chemicals are used to remove iron, suspended solids, organic color, and hardness from influent water.
In wastewater treatment these clarification aids help with the removal of other contaminants such as oil, phosphate and heavy metals. For raw water applications, polymer products help to eliminate the need for pH adjustment, decrease the load on demineralizers, increase filter throughout, and significantly reduce sludge volume.
Coagulation and Flocculation Process
Suspended matter in raw water supplies is removed by various methods to provide a water suitable for domestic purposes and most industrial requirements. The suspended matter can consist of large solids, settable by gravity alone without any external aids, and nonsettleable material, often colloidal in nature. Removal is generally accomplished by coagulation or flocculation. The combination of these processes is referred to as clarification.
