Water treatment chemicals

Municipal utilities, power plants, refineries, food and beverage plants, pharmaceutical sites, mines and pulp mills are the main buyers. Many purchase water treatment chemicals by tender and long-term contracts, and specialist service companies supply formulated blends together with dosing and monitoring.

Chemicals for drinking water must meet strict quality standards because impurities end up in the water people drink. In North America this usually means certification to NSF/ANSI/CAN 60, while European and other countries refer to EN standards or national lists of approved chemicals. Ask suppliers for these certificates, the active content, and limits for heavy metals, bromate and other contaminants. For industrial water, specify the system, water analysis, temperature and the problem you need to solve, and ask for a treatment proposal and trial support. Many products are corrosive or oxidising dangerous goods delivered in bulk tankers or IBCs.
