Problem: The Southwest Water Reclamation Facility in Cape Coral, Florida, pumps an average of 7 mgd. To combat algae buildup, the facility used motor-driven diaphragm pumps to dose sodium hypochlorite. The pumps were effective but required frequent maintenance and often experienced bleach leakage that damaged pumps and fittings, and crystallization that interrupted flow and wasted energy.
Solution: The plant team adopted SEEPEX Intelligent Metering Pumps to provide precision dosing with ultra-low pulsation. An integral drive accepts feedback from a flowmeter for process control.
Result: The pumps have required zero maintenance in 24/7 operation. The constant flow from the pumps greatly reduced on leaks caused by pressure fluctuation, according to Marcus Papp, maintenance supervisor. The need for pressure regulators and check valves has been removed. 937-864-7150; www.seepex.com
