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.
