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.
Previous installation at Harbour View
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.
