As a design-build contractor, Globaltech converted the City of Cooper City existing chlorine gas storage and feed system to a sodium hypochlorite liquid storage and feed system.
Globaltech provided design build services to convert the existing chlorine gas storage and feed system that served the Water Treatment Plant (WTP) and Wastewater Treatment Plant (WWTP) to a commercial grade sodium hypochlorite (NaOCl) liquid storage and feed system. The change from gas to liquid was to improve safety around the workplace and surrounding community. The conversion also eliminated EPA’s Risk Management Plan requirements for the site.
The City used a common chlorine building to house 2-ton chlorine gas cylinders and gas feed equipment to provide chlorine to both the WTP and WWTP. The chlorine building was equipped with an emergency chlorine gas scrubber.
The new sodium hypochlorite system was placed in the existing chlorine building. During the renovations, a temporary sodium hypochlorite tank with metering pumps were set up outside chlorine building to provide chlorine to the WTP and WWTP while the chlorine gas cylinder, scales, chlorinators, injectors, booster pumps, and chlorine gas scrubber were removed.
Four 3,000 gallon bulk storage HDPE tanks were installed with ultrasonic level indicators. Concrete curbs were poured inside the chorine building to provide secondary containment for the sodium hypochlorite storage tanks. Six metering pumps were installed to provide sodium hypochlorite, three for the WTP and three for the WWTP.
Globaltech permitted the project through the Broward County Health Department and the Cooper City Building Department.
