Specialty Chemicals to safeguard membrane performance, today and tomorrow

Since 1998, Professional Water Technologies (PWT) has focused on chemical manufacturing and supply for the membrane industry, with a product line developed around our unique dendrimer-based antiscalant chemistry for scale and fouling control. Growing in step with the membrane industry, we have developed solutions and services to support our customers who are addressing varied and difficult applications like seawater desalination and wastewater re-use. Today, PWT offers a complete portfolio of antiscalants, antifoulants, dispersants, cleaners, coagulants, biocides, and preservatives for even the most difficult of MF/UF and NF/RO source waters.

What We Do

At our Head Office in Vista, CA, we synthesize the dendrimer, the primary component for our SpectraGuard™ antiscalants and blended Lavasol™ and OptiClean™ cleaners, which gives us ultimate control over product quality. As the first company to offer an 11x concentrated formula, we have remained competitive in markets around the world.

To complement our chemistry, our Membrane Forensics™ offering includes autopsy and analytical work, technical support, and field service. Our team of experts is available around the clock to help you troubleshoot and optimize your membrane system.

Together with our broad network of international distributors, we are excited to offer you Forward Thinking Chemistry.
