What does nitrate removal mean in practice?
The selective anion exchanger exchanges nitrates for chlorides, and the RO membrane retains them without regeneration with brine at the point of consumption.
When does it matter?
Sulfates compete for space on the resin, and a depleted resin bed may allow nitrates to break through without changing the taste of the water.
Which solutions are related to it?
The method is sized based on the full anion composition and water consumption, and the result is controlled in the laboratory after launch and during operation.
