Biological Wastewater Treatment

Biological Wastewater Treatment

Aerofloat offers a wide range of Biological Wastewater treatment options for municipal and industrial wastewater applications. Microorganisms convert soluble organic impurities in wastewater to produce a biosolid.

Aerofloat Patented MBBR – Moving Bed Biofilm Reactor is the most commonly used treatment process, accompanied by the AeroDAF.

Biomedia, roots blowers as well as coarse/fine bubble diffusers are all offered as component based WWTP upgrades and retrofits.


Biological Wasterwater Treatment Process Available

MBBR - Moving Bed Biofilm Reactor

A combination of activated sludge and fixed film treatment. A tank is partially filled with Biomedia for bacteria to grow, increasing the concentration of microorganisms over a traditional activated sludge reactor.

SBR - Sequencing Batch Reactor

The sequencing batch reactor (SBR) is a fill, aerate, settle and decant activated sludge system for wastewater treatment. In this system, wastewater is added to a single “batch” reactor for biological treatment.
ALS (Air lock Syphon) decanters remove treated effluent from the reactor.

AS - Activated sludge

AS – Activated sludge  – Aerofloat offers traditional AS system for a simple aerobic treatment of industrial wastewater.

STP – Sewage treatment plant

With 40 years’ experience in sewage treatment plant design and construct projects, Aerofloat now offers small and large scale STP’s for remote sites such as mining, camp sites, resorts and caravan parks.

Aerofloat Patented Moving Bed Biofilm Reactor - MBBR

Aerofloat’s patent-pending MBBR technology provides a simple, low-maintenance and cost effective solution for biological wastewater treatment. The unique design of the aeration lances allows them to be removed from the reactor while the process is still operating, without draining the tank or removing the biomedia.

Aerofloat MBBR Features

Easy cleaning without downtime

The unique design of the Aerofloat MBBR aeration lances allows them to be removed for cleaning while the process is still operating. This prevents the need to drain the tank, remove the biomedia or shut the system down

Sealed and vented

The Aerofloat MBBR can be sealed and vented, preventing any unpleasant odours escaping.

Cost effective

The Aerofloat MBBR tank is made of polyethylene, which makes the system durable and cost-effective


The Aerofloat MBBR is a compact form of biological treatment system.
