Accel-o-Fac Upgrade for Nelson City Council WWTP

GURNEY ENVIRONMENTAL, the West Norfolk-based sustainable wastewater treatment solutions provider, have received an order from the Nelson City Council in New Zealand to supply Gurney’s exclusive Accel-o-Fac® wastewater treatment system upgrade for the city’s wastewater treatment plant.

The first phase of the order includes the supply of windpowered SERIES 3 aerator/mixers to replace the existing electric aerator/aspirators, which are costly to run and maintain (OPEX). The order is due to be shipped to New  Zealand in late January ready for installation in March/April.

Following a lengthy consultation process with Gurney Environmental, Nelson City Council chose the Accel-o-Fac system for its well-proven and time-tested sustainability credentials and its ability to improve the wastewater treatment process in facultative lagoons. The City Council also appreciated Accel-o-Fac’s ability to extend the life of the existing wwtp asset. The order also followed the successful demonstration of the Accel-o-Fac system with nearby

Australian water utilities including the Toora wwtp owned and operated by South Gippsland Water. At that Australian facility, the Accel-o-Fac upgrade improved wastewater processing and significantly reduced energy costs (OPEX).

Advanced Technology The Accel-o-Fac system is advanced technology that can be used to upgrade existing lagoon-based systems, providing accelerated processing rates, increased DO levels, elimination of short circuiting, accelerated disinfection, odour elimination and accelerated total sludge digestion — all of which allows greater loads to be applied to existing lagoons, thereby extending their life whilst improving performance.

Zero-to-Low Energy Costs

In many cases, the wind-powered Accel-o-Fac system can have a zero ongoing energy cost, yet provide robust treatment. In the case of the Holkham Estate installation operating for over 10 years in Norfolk, UK, the system has maintained superb effluent quality, no odours and no sludge removal or handling required over the decade of use.

Obviously, total ongoing OPEX is incredibly low. At Toora, Australia where an Accel-o-Fac system supplemented and reduced the need for existing surface aerators, the system’s extremely low operating costs provided better treatment and odour control while cutting overall energy costs by 72%, thereby completely paying for the upgrade.

Gurney Environmental continue to enjoy success with their export programme of manufacturing and supplying  extraordinarily sustainable wastewater treatment solutions to a growing number of wastewater treatment plant operators around the globe. The company's highly innovative and sustainable wastewater treatment solutions are time-proven to have provided operators with significant energy savings and improved processing power over several decades.
