Acid Neutralizing Filters


Reduction of Water Acidity

Acidic water in buildings has the potential to corrode plumbing lines and water-based systems that can result in heavy replacement costs of replacement of piping and components, constant investment, down time and labour costs. Symptoms of acidic water are bluish green stains on fixtures with copper plumbing; reddish stains with galvanized iron plumbing,  water system corrosion problems and plumbing leaks.

Rainfresh neutralizing filters are designed to improve (increase) the pH of water in such situations. They incorporate calcite or ground limestone (calcium carbonate) to raise the pH. When acidic water flows through the filter, hardness is added to the water that raises the pH of the water thus neutralizing the acidity. (Note: Hardness should be evaluated for down-stream applications). The media slowly dissolves and eventually needs to be replenished.

Rainfresh Neutralizing filters are available to suit various flow rates and pipe sizes (see table below). Systems must be sized based on normal service flow, as low flow situations can cause over-correction of pH.
