Water Treatment


Puri-Cal™ brand water treatment calcite is a safe, easy to use, natural product from high purity Pacific Northwest Limestone. It is specially selected and sized to optimally adjust pH in potable water systems. When used in accordance with standard water treatment practices it will gently and effectively adjust the pH of your water and help minimize corrosion problems in plumbing and appliances. Proper use of Puri-Cal™ can help water systems comply with the EPA lead and copper rule. When used in back-washing filter systems Puri-Cal™ can significantly clarify cloudy and turbid water.

Calcite is an increasingly important component in the professional water-treatment contractor’s tool kit. Calcite is not only used to increase the pH of acidic drinking water but is also used to re-mineralize water that is the end-product of Reverse Osmosis purification, decrease contamination from some heavy metals in waste and storm water runoff, remediate water used in mining processes and activities, and as part of biofilter odor control systems. Columbia River Carbonates has placed a strategic emphasis on participating in this technically challenging market and has developed the Puri-Cal family of products.

All Puri-Cal™ brands are Independently tested and certified by NSF to Standard 60. Live Safer®.

Additionally Puri-Cal ™ is approved by The Norwegian Institute of Public Health for use as alkaline filtering material in systems producing drinking water offshore.
