Accel-o-Fac is a zero-to-low energy wastewater treatment system requiring no sludge handling and utilising wind energy. In many cases, there is little in the way of ongoing operating costs.
Accel-o-Fac® is a long-term sustainable “All-in-One” wastewater treatment system. Based on the tried and proven facultative biological process, Accel-o-Fac® (accelerated facultative™) has successfully treated a wide variety of wastewater for many years. Accel-o-Fac® provides Water Companies with extremely robust, odour free wastewater treatment that requires little in the way of operator attention or maintenance and, best of all, no sludge handling or removal — truly “All-in-One” total treatment on site.
These benefits are accomplished with almost zero operating cost by employing wind power as the primary energy source and through the use of highly specialised equipment combined with a number of unique design, construction and operation techniques. The net result is a total “optimisation” of a purely biological process resulting in an overall acceleration of the processing rate. This “optimisation” enables Accel-o-Fac® wastewater treatment plants to be smaller than old-fashioned WSP designs — all at zero-to-low operating cost and without the use of expensive and complex conventional mechanical aeration, chemicals or significant manpower.
Enhancing the Facultative Biological Process
Accel-o-Fac® not only boosts natural oxygen transfer, but also provides an ideal quiescent zone for solids settling and self-digestion of the sludge — a fundamental and essential part of the “All-in-One” facultative biological total treatment process.
The Accel-o-Fac® system also eliminates the problems of short circuiting by radially dispersing and distributing the incoming organic load throughout the entire treatment volume. With Accel-o-Fac®, the entire cell volume and surface area are put to work with no dead spots and no “hot” or overloaded spots (such as near the influent area). This alone dramatically increases the processing capacity of the cells enabling it to automatically deal with shock loads.
Accel-o-Fac® can accommodate huge variations in flows without any operating problems. Storm water flows, peak flows, seasonal increases are all effortlessly handled.
Self Digesting Sludge
Long term studies prove these systems anaerobically self-digest all organics within the system with the inert materials accommodated for the life of the plant. That can be an important consideration with regulations and concerns regarding sludge disposal and handling. Accel-o-Fac® acheives this important benefit by ensuring correct loadings and detention times as part of the overall design process along with optimised conditions within the system.
O & M Considerations
Equipment maintenance for a typical Accel-o-Fac® system for a small community is minimal, requiring less than 10 man hours of mostly visual inspections annually. Lubrication of bearings occurs automatically via the special lubrication system, serviceable on an approximately semi-annual basis, and there are almost no consumable parts to replace over the years.
With the significant reductions in total operating costs as compared to conventional package or mechanical plants, the Accel-o-Fac® system is typically fully self-liquidating, meaning that the entire construction cost of the wastewater treatment plant can be paid for with just the reductions in operating costs alone as compared to other common alternatives.

Fast Capital Cost Recovery Through Reduced O&M
Data from an Accel-o-Fac upgrade at an existing wwtp shows the dramatic cost savings for a small treatment works by effectively replacing a single traditional surface aerator with the Accel-o-Fac system. The cost of the upgrade was recaptured quickly with additional savings every month.
