Welcome to Aerofloat

Aerofloat™ (Australia) Pty Ltd is an Australian owned company which specialises in the treatment of industrial wastewater and greywater.

Aerofloat designs, manufactures and installs simple, affordable wastewater treatment systems using its patented Dissolved Air Flotation (DAF) and patent pending Moving Bed Biofilm Reactor (MBBR).

The Aerofloat DAF technology uses a double hopper tank with a unique, patented hydraulic float removal system to funnel the waste float material from the top of the tank. Mechanical scrapers are not required.  The patented system is compact, mechanically simple and a more affordable DAF solution.

The patent pending MBBR has unique removable aeration diffusers allowing them to be removed from the reactor while the process is still operating, without draining the tank or removing the biomedia.

Aerofloat designs and constructs wastewater treatment plants to treat process wastewater from a wide range of trade waste industries, particularly the food processing industry (including dairies). It also provides products for the treatment and / or reuse of greywater for mining sites, residential developments and houseboats. Treatment capacities range from 7 to 800 litres per minute (L/min) or 0.4-50 m3 per hour (m3/h).

Company History

Aerofloat was formed in 2009 after a unique and compact Dissolved Air Flotation (DAF) unit was developed for the emerging houseboat market on the Murray River in South Australia.

Following the success of the product in South Australia, Aerofloat was awarded a government grant to further develop the patented design to treat much larger flow rates, particularly for the trade waste industry and the larger residential greywater market.  This two and a half year project saw the successful implementation of the Aerofloat 100 (treating 100L/min) – more than 7 times the capacity of the larger unit built for houseboats.

While Aerofloat still manufactures units for the South Australian and the Victorian houseboat markets, the core business has moved to the trade waste industry.  With this Aerofloat moved from a typical product supply only business to a full design, install and construct business.

Aerofloat has continued to build larger system to cater for the increasing customer demand – with the largest single DAF unit now treatment 50m3/h (800L/min).

Also, Aerofloat has entered the biological treatment market with the development of its unique Moving Bed Biofilm Reactor (MBBR).  Again, taking a proven technique and adding some smart engineering to create a maintenance friendly and cost-effective biological treatment solution.

With its core IP technologies combined with some standard “off-the-shelf” products, Aerofloat is now able to provide a fully tailored wastewater treatment solution.

What we do



The Aerofloat DAF product is available as supply only, in certain circumstances.  Houseboat units are generally supply only projects.  Larger industrial treatment plants typically require a level of upfront detailed design to ensure the correct Aerofloat unit is chosen for the given peak flows and composition.

Aerofloat has a distribution agreement with APEX Environmental in New Zealand where the Aerofloat products are supplied to APEX Environmental who then design, install and manage the local project.  Aerofloat is looking for further potential distributors across the globe.  Should you wish to become a distributor of the Aerofloat products please contact us at

Aerofloat also has access to a number of standard equipment pieces that can support the Aerofloat DAF and MBBR – e.g. sand filters to be placed after the DAF to achieve a superior effluent quality for water reuse.  Aerofloat is happy to supply these components also.


Aerofloat will design, supply and project manage the total construction of your wastewater treatment plant.  The typical model with industrial projects, is for the client to supply building support for the construction of slabs, buildings etc. as well as plumbing of wastewater to the treatment site.  Aerofloat site supervisors will work with subcontractors to ensure the successful execution of the agreed scope of work.

In the design phase Aerofloat engineers will complete a full site specification with 3D models of the proposed works.  Aerofloat will procure all componentry and ensure it is delivered to site in a timely manner.  Aerofloat site supervisors will be on site ensuring safety processes and procedures are executed and the installation of the system meets Aerofloat’s quality standards.  Aerofloat engineers will commission and test the plant on site, provide a site specific operations manual and complete thorough operational and maintenance training for all required staff.


With over 50 years combined experience in the wastewater treatment business Aerofloat engineers are happy to consult to assist with your wastewater problems.  Ray Anderson has over forty years’ experience in the biological wastewater treatment business.  This wealth of knowledge, coupled the IP of the Aerofloat DAF, the Aerofloat MBBR and access to other filtration componentry, provides a strong platform to tackle the most challenging of wastewater problems.

Should you require advice on improving performance of old technology or designing a green field plant us at for an initial obligation free discussion about your wastewater treatment needs.


As part of the typical industrial wastewater treatment design, chemicals are used for pH correction, coagulation and flocculation.  As such, Aerofloat is able to supply the necessary chemicals required to operate your plant successfully.

By using Aerofloat chemicals you can be sure that the most efficient and suitable chemicals have been sourced at the most competitive price.
