Automated Pure Water, Inc. introduces the TriShaft High Flo Retention Tank chemical mixing retention system. It features six built-in mixing chambers and three swirl chambers that reduce a drop of water to hundreds of microbubbles, which allows chemicals to mix and react five times faster than a standard retention tank. This concept allows reduction of overall system size, which needs only 13 inches (33 cm) of floor space. Constructed of all polyglass, noryl and PVC materials, the tank is pre-plumbed, 1.5-inch (38.1-mm) throughout and has a 0.375-inch (9.5-mm) drain for blow down. A tapped port is built in (should there be a need for gas off) and capped off.
