Ion exchange is very effective in removing nitrate from drinking water. Unlike other processes, ion exchange is selective so that you don't need to remove other ions to remove nitrate. The ion exchange process has a yield of 98 to 99%, Typically, 95% of the nitrate in the raw water is removed. This allows for partial treatment and blending with raw water to produce safe drinking water.

In the ion exchange process, water is passed through a packed bed of ion exchange resin. Nitrate ions are picked up by the resin and exchanged for harmless chloride ions. When the resin is fully loaded with nitrate, it is regenerated with a solution of sodium chloride (table salt).

The Advanced Amberpack Municipal System is a unique, low waste system for treating nitrate containing waters. It uses patented fractal technology to minimize waste volume to <0.3% of the total flow in many cases.
