Reverse Osmosis Membrane Chlorine Scavengers
AntiChlor formulations remove free and combined chlorine from RO system feedwaters to protect membranes from oxidation damage. Membranes can last for days or years depending on the care they receive. Chlorine in feedwater can permanently damage membranes, requiring them to be replaced. AntiChlor liquid is an extremely economical option for chlorine removal compared to other methods. It’s offered in two formulations, and both are certified for use in systems producing potable water. To make membrane care even simpler, our Avista Advisor software calculates dose and consumption rates of AntiChlor products for your convenience.
