Waste Water Solutions


Garratt-Callahan’s wide range of specialty coagulants and flocculants deliver effective dewatering of solids, increase throughput, and reduce sludge volume. All meet the demanding new standards for wastewater and process water treatment.

Compared with alum and other conventional coagulants, our liquid coagulants deliver both better clarification rates and lower sludge volumes. Effective at low dosages because of their high active content, Garratt-Callahan coagulants also work at a wider range of pH levels and reduce the need for acid or caustic treatment applications. Available in a full range of charge values and molecular weights, our emulsion, liquid, and dry flocculants increase production rates and lower dewatering costs.
