Sewage treatment consumes a lot of electricity. Researchers at a university in the United States recently developed a new microbial battery technology that increases the efficiency of sewage to produce electricity by 10 to 50 times. Using this technology, sewage treatment plants can not only achieve self-sufficiency in electricity, but also sell the surplus electricity. It can be expected that once this technology is put into commercial operation, the attitude of enterprises towards sewage treatment will become proactive
as to reduce the environmental pollution caused by sewage discharge.
Will this kind of sewage treatment cause air pollution due to the release of methane.
