Membrane elements with extended pH limits


Dows FILMTEC” membrane elements from FilmTec Corporation are guaranteed to withstand a wider pH range of 1-13 for membrane cleaning solutions. Typical cleaning pH limits are in the range of 3.5-10, referring to limits of 2-12 as harsh cleanings. Elements can be cleaned with the widest pH range in the industry, offering reverse osmosis (RO) and NF90 system owners lower cleaning costs and better system operation. The higher pH limit of 13 improves the removal of biofouling and organic fouling from the membranes, while the lower pH limit of one increases the efficiency of calcium carbonate removal, leading to longer operating time between cleanings and longer membrane lifespan.www.dow.comdowcig@dow.com
