Denitrat units are anionic resin filters retaining nitrates present in water, to be regenerated with sodium chloride. Regeneration can be programmed by volume/time. The system is to be sized according to daily water consumption, peak flow rate and nitrates level.

Denitrat units are made up of:

• head with hydropneumatic valve in plastic material and electronic timer VT 1000 AD

• cylinder in plastic material covered in fireglass containing anionic resin for nitrates removal.
