The resin will remove between 20 and 25g of Nitrate per litre of resin used. So if you have 40ppm of Nitrates in your tap water this equates approximatley to 0.04g - therefore a typical filter with 4 litres of resin would need regenerating after 2,000 litres of have passed through it. Please note this is a general guide and not "absolute" - We use volume - not weight, this is because sometimes it is delivery to us wet and other times dry - wet obviously weighs more that dry and dry is slightly less volume than wet as it is fluffy compared to compact - we will ship a level 1 litre jug when wet and + approx 5% when dry. One litre can weigh anywhere between 600g and 800g - hence weighing it is not accurate.
