Consider these options to improve energy efficiency and reduce the cost of treating wastewater
Abtin Ataei, Graduate School of the Environment and Energy, Science and Research Branch of I.A.U.
Typical industrial and municipal wastewater-treatment plants consume an amount of energy that can represent 50% of the facility's variable operating and maintenance costs. Most employ biological processes that rely on energy-intensive aeration systems whose energy consumption is approximately 0.5 kWh per m3 of effluent treated. This article discusses a variety of design and operating improvements that can be undertaken to reduce energy consumption in wastewater treatment....
