how much are filter for nitrates out of drinking water
Ion exchange units, reverse osmosis, or distillation all remove nitrate from drinking water. Note that boiling water does not remove nitrates and is not a treatment alternative. In fact, it increases nitrate concentrations as water evaporates. An ion exchange unit operates much like a household water softener.f nitrate-nitrogen levels are extremely high (greater than 110 mg/l) up to 90 percent may be removed. Unfortunately, remaining nitrate-nitrogen may still result in drinking water that exceeds the standards of 10 mg/l nitrate-nitrogen. Figure 2.
