Antiscalant is a pre-treatment water additive for reverse osmosis system that is highly effective in preventing the membranes from scaling. Before the feed water enters the reverse osmosis membrane, an antiscalant is injected into the water and sent the through the system. The chemicals create a time delay between the bicarbonate and the calcium magnesium. The delay allows the water to pass through the membrane before any chemical reaction, in which scale can form, occurs.
It is widely used to provide longer run times and extended element life resulting in reduced operating and capital costs. Effective scale inhibition and low chemical dosage.
