Chemtrade’s Water Solutions team operates an extensive North American manufacturing network, producing both industrial chemicals and customized solutions for municipal and industrial customers. Our water treatment products consist primarily of inorganic salts used as coagulants in the treatment of drinking water and wastewater* — helping provide clean, safe, and reliable water supplies across North America. In addition to water treatment chemicals, the team produces a line of poultry litter amendments that help growers control ammonia volatilization, supporting improved bird health and productivity.

The acquisition of Polytec in November 2025 enhanced Chemtrade’s Water Solutions segment by adding differentiated, value-added capabilities to its water treatment portfolio. With this addition, Chemtrade now offers integrated water solutions, including specialized chemicals, equipment, and services, to better serve food processing, industrial, and municipal customers.

Ammonium Sulphate (Liquid)

Liquid Ammonium Sulphate

Liquid Ammonium Sulphate (LAS) has become widely accepted as a stable and effective source of ammonia for chloramination. Alternatives such as anhydrous or aqueous ammonia require pressurized storage tanks as well as special handling and safety procedures.

LAS can be metered to deliver a precise amount of ammonia. The LAS chemical replacement ratio for anhydrous ammonia is 10:1, providing a chlorine to ammonia ratio of 3-5:1. However, replacement ratios of less than 10:1 have been achieved with LAS due to its chemical efficiency. Unlike the alternatives which experience vapour loss, all of the ammonia in LAS remains bound in solution until it contacts chlorine.
