Northumbrian Water have started on-site work preparation for the construction of an Aero-Fac® wastewater treatment system supplied by Gurney Environmental.

Dramatic Flow Variation Control

Process engineers at Gurney Environmental developed this specific Aero-Fac wastewater system for Northumbrian Water to meet a normal winter population of 200, but rising to a summer population of almost 3,000! This dramatic variation in flow from winter to summer can create serious issues for many wwtp designs. In this case, Northumbrian Water have been tankering away excess wastewater flows over the 150-pe SAF design with an associated high cost and carbon footprint.

In the analysis by Northumbrian Water’s consultants, Aero-Fac offered a well-proven and time-tested system with the flexibility and robustness of operation to be able to cost-effectively and easily accommodate this large flow variation.

Significant OPEX Cost Reductions

While Aero-Fac handles massive flow variations without significant operator intervention, the unique wastewater treatment system also utilises renewable wind energy and extremely low operating and maintenance cost aeration systems. Total annual operating costs are typically around 85% less than conventional activated sludge systems.

Aero-Fac also requires no sludge handling, removal, testing or disposal by completely self-digesting sludge within the system itself, thereby providing a truly long-term sustainable, low TOTEX, complete and total on-site solution.

Testimonials

We've already found that the ponds work a lot better, they are a lot cleaner and functionally look a lot better than what they were previously. It seems to be working at this stage, so we're quietly confident that it's going to be a good investment.

...there is no doubt about it, the ResMix system works! Having started with a volatile and inconsistent chlorine residuals in our supply, we are now using the WEARS product to mix and dose our tanks. We are not alone in our experiences here. All I can say is that the results speak for themselves.

Adding the Accel-o-Fac® system to South Gippsland Water treatment cells where traditional surface aeration was previously used allowed the corporation to significantly reduce energy use. The savings in kWh are excellent with one application saving 72% in energy compared to the previous year.

The fact that there is no associated sewage odours [with the Accel-o-Fac wwtp] meant that the system could be located relatively near to the village, and, after 10 years of use, no sludge removal has been needed.

These results show that the [ResMix] mixer is providing a fully mixed water column and preventing conditions for manganese and nutrient release from the sediments.

We are very pleased to be using this innovative management system in the reservoir at Pontsticill. This investment will improve the water quality for customers in the area and ensure they continue to receive a top quality supply of drinking water long into the future.

The Aero-Fac system at Windsor has to date met and exceeded our consent discharge levels, and we have been very happy with the system installed.
