Aerobic Wastewater Treatment

Aerobic wastewater treatment systems that produce high-quality secondary effluent for safe discharge

Aerobic wastewater treatment including activated sludge, fixed biofilm and biofiltration to break down waste.
Overview

We offer a full range of aerobic treatment systems that produce high-quality secondary effluent from industrial wastewater or sewage. Our technologies include conventional activated sludge, moving bed biofilm reactors (MBBRs) and membrane bioreactors (MBRs).

What is aerobic wastewater treatment?

Aerobic treatment of wastewater is a biological process that uses oxygen to break down organic contaminants and other pollutants like nitrogen and phosphorous. Oxygen is continuously mixed into the wastewater or sewage by a mechanical aeration device, such as an air blower or compressor. Aerobic microorganisms then feed on the wastewater’s organic matter, converting it into carbon dioxide and biomass which can be removed.

What is aerobic wastewater treatment used for?

Aerobic treatment is usually used to polish industrial wastewater pre-treated by anaerobic processes. This ensures the wastewater is fully degraded and can be safely discharged in accordance with strict environmental regulations. Aerobic treatment processes are suitable for a range of industries such as food & beverage, chemical and municipal.

What types of aerobic wastewater treatment system are there?

There are several different technologies for the aerobic treatment of wastewater and sewage. These include:    

  • Conventional activated sludge: organic matter is broken down by aerobic microorganisms in an aeration tank. This forms biological flocs (sludge) which are then separated from the treated water in a sedimentation tank.
  • Moving bed biofilm reactor (MBBR): biofilm grows on plastic carriers suspended and circulated in an aeration tank. These are kept in the tank by retention sieves.
  • Membrane bioreactor (MBR): advanced technology combining the activated sludge process with membrane filtration.

What are the benefits of aerobic wastewater treatment systems?

Aerobic treatment of wastewater is a stable, simple and efficient process that produces high-quality secondary effluent. The resulting sludge is odour-free and can be sold as excellent agricultural fertiliser.

When combined with anaerobic treatment, aerobic treatment systems ensure complete contaminant and nutrient removal. This means your wastewater can be safely discharged without breaching stringent environmental regulations.
