The Rahway Valley Sewerage Authority (RVSA), which operates a large wastewater treatment plant in New Jersey, embarked on a green co-generation waste-to-energy project to power a portion of its operations. The plant performs primary, secondary, tertiary and sludge treatment processes in serving over 250,000 residential customers and 3000 industrial and commercial customers in a 40-plus square mile region. A maximum peak flow of 105 million-gallons-per-day (MGD) can be processed daily. The plant’s management team became interested in pursuing the gas-to-energy power co-generation system for both environmental and cost reasons.
