PSI Water Technologies- UGSI; PSI, Microclor, PAX, Monoclor – manufactures an On‐site generation disinfection system that applies electricity to a solution of salt and water to produce sodium hypochlorite. Incoming water first goes through a softener, then splits into two lines. One line goes to the electrolytic cell, where electricity is applied to the brine solution, and the other goes to a brine storage tank. Near‐saturated brine is injected into the softened water that is going to the electrolytic cell.
