King Lee Technologies uses specialized chemistry and process support to optimize operational costs for reverse osmosis (RO) and nanofiltration (NF) membrane systems. Since originating membrane support chemistry in 1977, we have benefited thousands of brackish ground, surface, seawater, and wastewater facilities. We formulate and manufacture specialty antiscalants, antifoulants, membrane cleaners, sanitizing and preservative agents, microbiological control chemistry, and coagulants. We distribute membranes and cartridge filters and perform off-site membrane cleanings. Our technical experts conduct membrane autopsies, cleaning studies and provide process support through chemical testing, piloting, and our innovative web-based normalization software, iWaterPRO. As your partner in the pure water industry, we commit our decades of field experience to support plant managers, system operators, OEMs, consulting engineering firms and distributors. We will help you treat challenging water, increase product recoveries, extend cleaning intervals and excel beyond each new challenge to maximize the productivity, efficiency and life of your membrane systems.
