Water disinfection with dry calcium hypochlorite
Constant Chlor water-treatment systems use dry calcium hypochlorite and are designed as an alternative to gas or liquid chlorination. The Constant Chlor product line features a patented spray technology and is fully customizable. It can be installed as a standalone system or be integrated with other process and control equipment. The Constant Chlor Model MC4-50 feeder (photo) sets itself apart from typical erosion feeders due to its spraying process that dissolves materials from the bottom of the briquette bed. The feeder is NSF/ANSI 61 certified to prepare and automatically deliver a consistently accurate dose of liquid-available chlorine for drinking water applications. Constant Chlor Plus briquettes are designed specifically for use in Constant Chlor feeders, and are NSF 60 certified for use in drinking water. These pillow-shaped briquettes create a well-packed spray bed, compared to generic tablets that leave gaps, says the manufacturer. Booth 1644 — Lonza Water Treatment, Alpharetta, Ga.
