In 1999, United Water Pennsylvania, a water utility serving more than 150,000 people in eight counties in the Keystone
state, installed a ClorTec® Model MC 100 System to replace chlorine gas cylinders at its Hummelstown Water Treatment Plant (WTP) just east of Harrisburg. The plant is a conventional WTP consisting of prechlorination, coagulation, clarification, granular media filtration and post chlorination. The water source for the Hummelstown plant is the Swatara Creek, the turbidity, pH alkalinity and hardness of which can vary significantly.
As part of the U.S. Environmental Protection Agency’s (EPA) Environmental Technology Verification program (ETV), the EPA and NSF International verified the performance of the Hummelstown system at installation. The concentrated hypochlorite generator stream from the treatment system underwent a twice-daily analysis from March 8 to April 6, 2000 using the Standard Methods for the Examination of Water & Wastewater established by the American Public Health Association, the American Water Works Association and the Water Environment Federation.
