Wastewater Treatment
Don't waste waste water.
Previous generations of waste water professionals have often accepted the high costs of operating waste water treatment facilities as a consequence of meeting their discharge permit requirements. However, as the cost of energy rises and emphasis on renewable energy increases, municipalities are now seeking cost-effective and energy-efficient solutions. Jenbacher gas engines provide tailored solutions that result in long-term savings for waste water treatment plants.
Water treatment processes in waste water treatment plants (WWTP) include energy-intense operations, such as aeration and pumping. Second only to personnel, the leading expense to WWTP owners is the cost of energy – and these costs are on the rise. As electricity prices rise, plant operators are facing increasing energy costs in order to meet discharge permit requirements.
Jenbacher provides a solution for rising operating costs. In plants that employ anaerobic digestion for biosolids treatment the sewage gas that is produced can be used to produce electricity. Using modern gas engines, this renewable energy source can efficiently and reliably be converted into electricity. This can cover up to 80% (100%) of a plant’s electricity needs and eliminate the need to use fossil fuels to heat the plant.
Gas produced in anaerobic digesters from municipal WWTPs generally contains 55% to 65% methane and has a typical heating value of 6 kWh/Nm3. As a general rule, approximately 1 MW of electricity can be generated from the biosolids of waste water treated from approximately 500,000 population equivalents.
