We offer a full range of aerobic wastewater treatment technologies that produce a high-quality secondary effluent. Our technologies include conventional activated sludge treatment, Moving Bed Biofilm Reactor (MBBR) and membrane bioreactor (MBR).

What is Aerobic Treatment?

Aerobic treatment is a biological process that uses oxygen to break down organic matter and remove other pollutants like nitrogen and phosphorus. It converts the organic matter into carbon dioxide and new biomass. During aerobic treatment, oxygen is continuously required so forced air from an air blower or compressor is mixed with the wastewater. The aerobic bacteria feeds on the waste in this water and aerobic treatment takes place.

Aerobic Treatment Uses

Aerobic treatment is used to achieve maximum degradation while meeting the strict regulations set by environmental agencies regarding what is released into the air, ground, or water.

Aerobic treatment systems offer a number of benefits:

  • They play an important role in the wastewater treatment process ensuring that wastewater can be discharged safely in order for companies to meet strict environmental requirements
  • The stabilised resulting sludge is odour free and makes an excellent fertilizer
  • The operation is relatively simple.
