What water treatment chemicals do you supply for industrial systems?
We supply antiscalants for RO and cooling systems, coagulants and flocculants for clarification, liquid and solid biocides for microbiological control, pH adjustment acids and caustic, sodium bisulfite and sodium metabisulfite for dechlorination, and corrosion inhibitors for distribution piping. NSF/ANSI 60 certified products are available for all potable water applications.
What is an antiscalant and how does it protect RO membranes?
Antiscalants are threshold inhibitors dosed at 2-5 ppm into RO feed water. They interfere with crystal nucleation and growth of sparingly soluble salts such as calcium carbonate, calcium sulfate, barium sulfate, and silica. Without antiscalant, these salts precipitate on membrane surfaces as the concentrate stream becomes more concentrated during the rejection process, causing irreversible scaling and flux loss.
How do I select the right antiscalant for my feed water?
Antiscalant selection is based on a scaling index calculation using your feed water chemistry analysis. Key parameters are calcium, magnesium, barium, strontium, sulfate, carbonate alkalinity, silica, iron, and pH. We use Langelier Saturation Index and Stiff-Davis Index calculations, plus proprietary scaling models for silica and barium sulfate, to select the correct product and dose rate for your recovery ratio target.
What is the difference between a coagulant and a flocculant?
Coagulants (alum, ferric chloride, or cationic polymers) destabilize colloidal particles by neutralizing their surface charge, causing them to stick together. Flocculants (high-molecular-weight anionic or nonionic polymers) bridge the destabilized particles into larger settleable flocs. Coagulants are typically added first at the rapid mix stage, followed by flocculants at the slow mix stage before clarification.
Are your chemicals NSF certified for use in potable water systems?
Yes. All chemicals intended for contact with potable water carry NSF/ANSI 60 certification, which sets maximum allowable concentrations and requires independent third-party testing. We provide NSF compliance documentation and Safety Data Sheets with every order. For food and beverage applications, we can also supply chemicals meeting FDA 21 CFR requirements where applicable.
How should industrial water treatment chemicals be stored?
Store liquid chemicals in secondary containment away from incompatible materials. Antiscalants and biocides are typically stable for 12-24 months at 40-90 degrees F. Keep acids and caustics separated and clearly labeled. Solid chemicals should be kept in dry, sealed containers. All storage areas should have emergency eyewash stations and be ventilated adequately. We include storage and handling guides with each shipment.
