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

NEO RE300 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 Neo RE300TM 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 RE300 to
    improve clarifier performance and potentially eliminate the need for costly tertiary filtration
  • Neo RE300 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 Technologies 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.

Neo RE300 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. Neo RE300 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.

Neo RE300 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.

RE300 forms a dense precipitate that settles faster than ferric- or alum-based coagulants, helping to improve clarifier performance and achieve ultra-low phosphorus limits without the need of costly tertiary filtration systems.


“Neo RE300 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 Neo RE300. 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 Neo RE300.”

“Over 50 wastewater plants in the United States are already using Neo RE300 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 Neo RE300 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.”

Neo RE300 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.
