Rotork CMA process control actuators deliver a compact solution for a new chemical dosing application at a water treatment plant expansion at the City of Loveland, Colorado USA.
The chemical dosing skids are part of a new chemical storage building, housing two giant tanks with a capacity of 46 MGD.
Operating mostly CPVC ball valves and some 4” butterfly valves on the chemical feed pump main and bypass lines, 21 CMQ 500 actuators control the delivery of chemicals to the various processes. The skid-mounted valves and pumps control the dosing of alum, polymer, sodium hypochlorite, fluoride, chlorine dioxide and sodium bisulphite.
The CMA range of modulating actuators are manufactured in a series of sizes for linear, quarter-turn and rotary control valve and pump applications demanding precise position control and continuous modulation. The actuator design enables simple, safe and easy set-up via an internal electronic 6-segment LCD display and push button configuration.
