    2021-7-4 · Aluminum-based coagulants in drinking water treatment are widely used across Canada. According to the literature, thepresence of aluminum in drinking water poses possible risks to humans. Preliminary studies investigating the use of alterna-tive coagulating agents such as iron-based coagulants, lanthanide salts and organic coagulants have already revealed thattheir implementation is possible, but require further studies concerning their technical, economical, social and environmentalimpacts. The identified alternative coagulants need on-site studies, operator formation and/or further research and develop-ment for their industrial utilization and the production of safe drinking water.
