Alkaline Aqueous Environment The use of alkaline aqueous solutions may reduce or eliminate annual reporting under SARA Title III, Section 313 (Toxic Chemical Release Reporting). The rate at which closed-loop cleaning systems generate waste streams, is much less than that of open-loop systems. The waste may be in the form of contaminated filters and reverse osmosis membranes. Do not assume that you can automatically put your wastewater directly down the drain. Contact your local publicly owned treatment works (POTW) first and thoroughly discuss all aspects of your proposed cleaning system. Water consumption may be an issue in areas with low water supplies.
