Abstract

A threshold agent composition and methods of using the same to produce hypochlorite and other effluent streams from an electrochemical cell without the detrimental effects of hard water scaling are disclosed. The invention further discloses use of chemistries to prevent hard water scale formation in various electrochemical cells to enhance cell longevity without decreasing chlorine, hypochlorite or other effluent production.
