Sequestration

Potable and non-potable water can be adversely affected by elevated mineral content. Iron, manganese and calcium found in groundwater and surface water supplies have the potential to oxidize and create aesthetic and physical concerns for water utilities. In the presence of chlorine, elevated pH, and extreme temperatures (hot water heaters, dishwashers, etc.) iron and manganese precipitate to form oxides in distribution systems.  These precipitates develop in tuberculation that can lower C factors (flow), increase chlorine demand and result in red water or black water at the customers tap. In addition calcium precipitates form cloudy water and scale in the distribution system and on customer fixtures.

Carus has developed a complete line of sodium and potassium-based phosphate blends that sequester high levels of minerals (Fe, Mn, Ca). The Carus polyphosphate blends create a ring like structure around the molecule to create compounds that are resistant to oxidation and precipitation. Carus polyphosphate blends utilize long chain threshold treatment technology to create extremely stable blends to keep mineral in solution over longer periods of time and in a variety of water quality conditions. The use of Carus polyphosphate blends eliminates red/brown water, cleans existing tuberculation, improves C- Factors (flow) and minimizes scale formation in distribution systems. Additional benefits include improved disinfection (lower chlorine demand), effective corrosion control at lower pH levels and improved flushing programs.  

Carus sales and technical advisors work with you to evaluate your water quality and recommend effective treatment solutions for all types of water treatment facilities including groundwater and surface water, conventional filtration and membrane technology. Carus sequestering programs are supported by our full time technical service and laboratory teams. The support includes site visits and water quality testing to insure effective treatment recommendations.      

Carus products which support the sequestration treatment objective include:
