Corrosive Water Problems
Corrosive Water Problems

Acid, neutralizing filters are very simple ,water, treatment units that are intended to increase pH and add calcium thereby decreasing corrosivity. They consist of a tank filled with calcium carbonate (limestone) chips, marble chips, magnesium ,oxide,, or other alkaline material. The ,acid, neutralizing filter is usually installed after the pressure tank.

The most common metals are steel, ,copper,, and ,copper, alloys. If the ,copper, is allowed to corrode, the ,copper, ions in the water quickly plate out on the steel in the system, causing galvanic corrosion of the steel. Chilled water closed loop inhibitors must provide good protection for steel, ,copper,, and any ,copper, alloys that are in the system.
