Gravity Return Systems
|
A gravity return system can be specified when the chlorine effluent is to be returned to the main water stream in an open tank, channel, or filter and when the chlorinator can be physically located at an elevation higher than the re-injection point. The system routes a sidestream of the main water flow through a simple rotameter and valve used to adjust the flow of the chlorinator. The water contacts only the tablets at the bottom of the feeder, so tablets at the top stay dry while those contacting the water erode at a predictable rate according to the amount of water that enters the chlorinator. Highly accurate chlorine dosage is achieved simply by controlling the water flow rate. Because nothing moves but the water, the PowerPro ® gravity return system represents the ultimate in reliability with negligible capital costs. The non-pressurized system also eliminates the potential of chlorinated solution spraying out of a corroded or broken pipe. PowerPro Gravity Return Systems
