Phosphates

Carus is the leading manufacturer and supplier of phosphate-based corrosion control and sequestration technologies in North America. With over 100 custom blend ratios—including orthophosphates, zinc-orthophosphates, poly-orthophosphates, and polyphosphates—our phosphates are designed to meet a wide range of water quality needs. All products are NSF certified and rigorously tested to meet our QA/QC standards. Our highly experienced support and sales teams work closely with customers to deliver timely, customized solutions that ensure optimal product performance.

Carus phosphates are designed to tackle critical water quality concerns, including corrosion control, lead and copper mitigation, and scale prevention. Our phosphates protect infrastructure, improve water clarity, and ensure compliance with EPA Lead and Copper regulations. By forming a protective film on metal surfaces, Carus phosphates extend the life of water distribution systems, reduce chlorine demand, and enhance flow (C-factors), making them a preferred choice for municipalities.

Applications:

  • Corrosion Control: Protects pipes, valves, and household plumbing, preventing red/brown water and maintaining system integrity.
  • Lead and Copper Reduction: Mitigates lead and copper release, ensuring safer drinking water.
  • Scale Prevention: Reduces scale buildup and cloudy water, improving system efficiency and reducing operational costs.

Carus’ phosphate solutions deliver proven results in safeguarding water infrastructure and ensuring high-quality water for communities.
