WTR ANTISCALE 8011 prevents the accumulation of compounds that can cause clogging on the membrane surface in reverse osmosis systems. WTR ANTISCALE 8011, Polyamide composite reverse osmosis or nanofiltration membranes; It is blocked by cations such as calcium magnesium, which gives hardness in the feed water, and by scale and dissolved metal hydroxides formed by silica, sulfate, carbonate, bicarbonate anions. This causes the permeate flow rate to decrease. The scale inhibitor should be dosed to the membrane without stopping to prevent scale formation. It can be used safely, especially in waters with high silica content. It delays membrane contamination due to its dispersant feature. It also prevents the accumulation of iron oxides with its chelating feature. It can be used safely in both high and low pressure membrane systems.
