Our Mission

CrossTek Membrane Technology was founded on the belief that membrane technologies have a major role to play in solving global water challenges.  CrossTek’s focus is industrial markets with the most challenging wastewaters.   CrossTek USA offers solutions based on ceramic ultrafiltration, disc tube reverse osmosis or DTRO, and spacer tube reverse osmosis or STRO.  CrossTek USA manufactures the DTRO and STRO membrane modules CrossTek China offers the Aquazoom brand of STRO and DTRO.  Our Aquazoom membrane modules are installed in over one hundred systems around the world, including China, which provided our beachhead market in landfill leachate treatment.  We have a history dating back to the 1980’s when the DTRO was first introduced to the market place CrossTek is currently expanding its business beyond our beachhead market into other market segments in China and we are also launching our offering into North America
