ClariPhos™ Rare Earth Coagulant:
Remove more phosphorus, produce less sludge.


Learn about ClariPhos™, a game-changing rare earth coagulant that outperforms aluminum- and iron-based alternatives for phosphorus removal.

ClariPhos™ enables wastewater treatment plants to achieve phosphorus limits of 0.07 mg/L or lower without the need for costly tertiary filtration systems. This unique coagulant improves clarifier performance, reduces sludge production and offers many other operational, economic and environmental advantages.

Bishop Water’s ClariPhos outperforms conventional coagulants because it is made from lanthanum and cerium, rare earth elements that form a strong, crystalline bond with phosphorus and produce a denser, more stable precipitate that settles up to two times faster.

Switching to ClariPhos is easy. In many cases, it’s as simple as replacing conventional iron- or aluminum-based coagulants with ClariPhos. Once the switch is done, wastewater plants can continue using their existing chemical treatment equipment, but with far better results.

Several treatment plants in Ontario are using or evaluating ClariPhos and are experiencing favourable results. Over 50 plants in the US have already switched to rare earth coagulant to comply with stringent phosphorus discharge regulations and to achieve other operational benefits such as:

  • Up to 50% reduction in sludge production;
  • Up to 40% higher attained solids in dewatered sludge;
  • 30-70% dose reduction over alternatives;
  • Less acidic than ferric or alum. Less likely to affect pH and require pH adjustment;
  • Low freeze temperature (-40C) eliminates heated storage or pipe heat tracing;
  • Non-hazardous rating, safer to handle than Al- or Fe-based coagulants;
  • Inhibits struvite build up.

Lagoon Sludge Cleanouts
Removing accumulated sludge from a lagoon is a fast, cost-effective way to restore treatment capacity and performance. But before the dredges, diggers and pumps can begin their work, project teams must carefully evaluate, estimate and plan to ensure the project proceeds smoothly and is completed on time and on budget.
