Northumbrian Water have completed the construction at Waren Mill of an extraordinarily flexible, low carbon footprint, dramatically low Total Life Cost Aero-Fac® wastewater treatment system supplied by Gurney Environmental.
Extraordinary Flow Variation Capability
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. At this particular location, Northumbrian Water had been tankering away excess wastewater flows over the 150-pe SAF design with an associated high operating 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.
