Following the successful use of the Accel-o-Fac® wastewater treatment upgrade at the Harbour View wwtp (owned and operated by the Jamaican National Water Commission), Gurney Environmental have won a further order to supply and install the first phase of an Accel-o-Fac upgrade for the Greater Portmore wwtp.

The installation of the Accel-o-Fac® wastewater treatment upgrade is due to take place in the later part of 2017 and follows the recent installation of the same upgrade system in New Zealand for the Nelson City Council at their Bell Island wwtp earlier this year. This newest order underpins Gurney Environmental’s commitment to developing its overseas exports as well as the growing acceptance of the company's highly sustainable wastewater treatment technology worldwide.

The Greater Portmore Accel-o-Fac® wastewater treatment upgrade option was chosen by the NWC based on its well proven and time-tested sustainability credentials, plus its ability to improve the wastewater treatment process in primary facultative, secondary and polishing lagoons. The system enables operators to extend the life of their existing wastewater treatment assets.

The Accel-o-Fac® system is advanced technology that can be used as a new-build design or to upgrade existing lagoon based systems (WSP’s), providing substantially accelerated processing rates, increased DO levels, elimination of short circuiting, uniform loading of the cells (no influent zone hotspots), 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.

The installation of the Greater Portmore Accel-o-Fac® wastewater treatment upgrade will improve the load capacity of wastewater treatment infrastructure in the Kingstown area and has been chosen by the National Water Commission as their preferred solution for enhancing treatment capacity at the wwtp in response to the development of new homes in the area.

The Accel-o-Fac system uses wind power as its primary energy source, of which Jamaica has a plentiful supply! Eliminating the reliance on electricity — which can be intermittent in some parts of the country and cost as much as 40 cents/KWH — is critical for sustainable wastewater treatment. Put simply, energy intensive systems are impractical for reliable sanitation.

As well as projects involving the upgrading of existing infrastructure, Gurney Environmental are also working with local consultants on the Island to show how the Company’s Aero-Fac® system can be used as an alternative to activated sludge for new-build plants in peri-urban areas. Aero-Fac can provide activated sludge quality effluent, but without the high CAPEX and continuous ongoing OPEX costs associated with activated sludge. Aero-Fac also has a fraction of the maintenance requirements, making the system an ideal alternative to activated sludge where the total cost of wastewater treatment is an issue.

When an existing primary cell is first converted to an Accel-o-Fac system, the windpowered SERIES 3 aerator/optimisers re-suspend the light sluff layer covering the sludge blanket. The aerobic action quickly digests this material and begins to clarify the entire upper water column creating an oxygen rich environment ideal for accelerated BOD removal and aerobic biochemical stripping of noxious gases.

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.

Richard Kirby Regional Sewerage Business Unit Manager Nelson, New Zealand

...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.

Doug Moorby Manager of Engineering Operations Norromine Shire, Australia

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.

Brett Vurlow South Gippsland Water Victoria, Australia

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.

Roy Samuel Capital Delivery Manager, Welsh Water - Dwr Cymru

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.
