Minntech introduces specially formulated Minnclean® AC and TF cleaners, available in a powder form in two, four-pound containers or a 35-lb. pail. AC acidic (low pH) membrane cleaner compounds are designed for use on thin film composite (polyamide) RO membrane systems and are especially formulated to remove mineral scale (calcium carbonate) and metal hydroxides from the membrane surface. TF alkaline (high pH) membrane cleaners remove organic foulants such as grease, grime and biological matter. http://www.minntech.comftginfo@minntech.com
