Anaerobic is a process that takes place in the absence of oxygen, such as the digestion of organic matter by bacteria in a UASB-reactor. Anaerobic treatment works by breaking down unwanted organic substances in wastewater or materials without required dissolved oxygen. Nevertheless, anaerobic bacteria do have the capability of using oxygen within oxides or even acquiring it from biological materials within wastewater. Anaerobic systems are very beneficial throughout industrial plants in the applications of managing food and beverage production, or even sewage treatment plants.

Advantages of Anaerobic Treatment

Anaerobic treatment has been a successful technological usage in wastewater treatment, specifically for extremely contaminated wastewater. Anaerobic treatment provides two primary benefits that describes its greater effectiveness in comparison to conventionally used aerobic activated sludge treatment:

  • Generating renewable energy that can produce electricity and consistent heating
  • High reduction of sludge production compared to aerobic treatment
