Bishop Water and Neo Chemicals & Oxides introduce a rare-earth-based coagulant to help wastewater treatment plants affordably achieve ultra-low phosphorus limits

ClariPhos binds tightly to phosphorus at a 1:1 molar ratio so much less is needed to achieve excellent phosphorus removal. Ferric or aluminum-based coagulants adsorb to the surface of phosphorus at about 5:2 molar ratio so much larger amounts are needed to reduce phosphorus levels in treated effluent.

  • New ClariPhos rare-earth-based coagulant enables wastewater treatment plants to chemically achieve regulatory requirements for ultra-low phosphorus limits in treated
    effluent – as low as 0.07 mg/L.
  • Operators can easily replace conventional ferric- or alum-based coagulants with ClariPhos to improve clarifier performance and potentially eliminate the need for costly tertiary filtration
  • ClariPhos rare earth coagulant offers a simple, cost-effective method for wastewater plants to dramatically reduce phosphorus discharge to sensitive water bodies that are at risk of algae blooms or eutrophication.

Renfrew, ON, May 7, 2019 — Bishop Water and Neo Chemicals & Oxides are introducing a new rare-earth-based coagulant to the Canadian wastewater industry that can help wastewater treatment plants easily and cost-effectively achieve ultra-low phosphorus limits—as low as 0.07 mg/L—without the need for costly tertiary filtration systems.

ClariPhos is a rare-earth-based coagulant that offers a simple, affordable way to achieve significant phosphorus reductions in treated effluent by simply replacing conventional ferric- or alum-based coagulants with this advanced treatment technology. ClariPhos could also help to significantly enhance the efforts of regulators and conservation authorities working to protect sensitive water bodies from eutrophication and algae blooms linked to phosphorus discharge.

ClariPhos outperforms conventional coagulants because the rare earth minerals it contains bond more tightly to phosphorus to form a denser, heavier precipitate that settles about two times faster than alternatives. This not only improves clarifier performance but also dramatically reduces both the amount of coagulant used and the volume of sludge produced to achieve high phosphorus removal.

“ClariPhos is a game-changing technology that could help communities achieve stringent phosphorus limits without spending millions in capital costs for filtration equipment and ongoing operating costs,” said Kevin Bossy, CEO, Bishop Water Technologies. “Many wastewater treatment plants already have chemical feed equipment in place as part of their phosphorus reduction programs that are capable of delivering ClariPhos. Enhancing the performance of this equipment and achieving ultra-low phosphorus levels could be as simple as replacing the current ferric- or alum-based coagulant with ClariPhos.”

“Over 50 wastewater plants in the United States are already using Neo ClariPhos to achieve stringent phosphorus limits, optimize their treatment processes, and protect sensitive aquatic ecosystems from excess phosphorus discharge,” said Alan Weber, General Manager – Water Technologies, Neo Chemicals & Oxides, an affiliate of Neo Performance Materials, Inc. (TSX: NEO). “We are confident that ClariPhos will deliver the same benefits to Canadian wastewater
treatment plants and we look forward to working with Bishop Water Technologies as our representative in this important marketplace.”

ClariPhos rare-earth-based coagulant provides a number of other benefits that can help wastewater treatment plants achieve significant operational efficiencies and cost savings over conventional coagulants, including:

  • Reduce sludge production by up to 70%;
  • Achieve up to 30% higher attained solids in dewatered sludge;
  • Maintain chemical dosing and performance in temperatures as low as -40C;
  • Inhibit the formation of struvite;
  • Safer for the environment; consistently passes Whole Effluent Toxicity testing; and
  • Safer for operators; rated non-hazardous.
