Automated Chlorine Control Brings Precision to Water Reclamation Operation

Using reclaimed water for non-potable purposes as a means of conserving potable water supplies is the most prevalent method of water reuse in the United States today. One of the significant challenges for water reclamation facilities is to keep up with the demands for safe, compliant chlorine (Cl2) treatment. One utility that is effectively meeting this challenge is Southern California’s Otay Water District.

Pulsed-Bed Sand Filters Meeting California Requirements

Wastewater is being reclaimed for non-potable uses. The use of this water is alleviating water shormance of the valve.

In addition, buried manually-actuated valves are easier to design and install if the operating valve shaft is horizontal and the gearbox input shaft is oriented toward the ground surface.

One concern with orienting the valve shaft axis horizontally is hydrostatic torque. Hydrostatic torque is a sizable operating torque component on large valves.
