Aero-Fac® Wastewater Treatment System
100% Total On-Site Treatment
Aero-Fac® is a high-process-rate, modular wastewater treatment system that has been well proven in a variety of municipal and industrial wastewater applications in all types of climates. Aero-Fac® employs an advanced and optimised form of a completely biological aerated facultative treatment process that automatically adjusts to handle extreme variations in flows and loadings. Aero-Fac® incorporates fast and easy construction techniques, uses little energy, requires exceptionally easy operator skills, almost no maintenance, and yet produces excellent effluent quality that can be superior for reuse and irrigation.
Suitable for Large, Medium and Small Populations
Aero-Fac is modular and can be scaled to handle any size flow and population. The modular design allows phased construction or multi-location options. Aero-Fac® can be a complete treatment works providing total wastewater treatment for municipal or industrial wastewater. Aero-Fac® requires minimal maintenance and operations, is odour-free and requires no sludge handling. Aero-Fac® provides a relatively small footprint solution with incredibly low OPEX and competitive CAPEX for a total treatment solution.
Mechanically & Biochemically Simplified For Reliability, Low OPEX & Capital Equipment Longevity
By employing a much more biological underlying process — the facultative biological process — significant costs can be eliminated in both the initial capital costs (CAPEX) of construction and equipment and the ongoing 20-year operating costs (OPEX). Facultative processing – a free gift of nature – can stabilise wastewater more thoroughly than standard mechanical treatment, and do it for a fraction of the cost and complexity.
Advanced methods developed and used by Gurney Environmental in the Aero-Fac® system enhances the natural facultative biological process's ability to fully stabilise wastewater while simultaneously self-digesting all incoming sludge, all without odour.
Using a pure biochemical, natural process with supplemental process enhancing technologies provides 1) a massive aerobic processing section, 2) a specialised facultative bacterial zone, 3) plus a full anaerobic sludge digestion section for total 100% on-site treatment. Additionally, special attached biofilm technology is available from Gurney Environmental for further polishing of effluent. This fundamental difference creates a major difference in initial costs and ongoing 20-year operating and maintenance costs.
Aero-Fac® Offers Clear Benefits

100% Stainless Steel
No plastic. No rubber membranes. No hoses. No poly materials at all. 100% of the critical diffused air aeration modules and headers are stainless steel and designed to last a lifetime with virtually no maintenance

No Membrane Maintenance
The entire diffuser assembly is self-cleaning. Nor are there any membranes to clean or replace or any moving parts whatsoever. Eliminating membrane replacement alone can save thousands of pounds annually.

Lo-Pressure Blowers
Aero-Fac® uses low-pressure fan blowers requiring virtually no maintenance, practically no routine replacement parts and an almost unlimited lifetime.

Energy-Free Aeration
Windpower provides 30-80% of the energy needed for wastewater processing. Unique wind powered SERIES 3 aerator/mixers have been proven in severe wastewater treatment applications for years, providing aeration, process acceleration and biological optimisation.

High Quality Effluent
Water from Aero-Fac® treatment systems not only meets rigid standards, it is also better in overall quality due to advanced stabilisation of all biochemistry. This makes it ideal for water reuse options.
