BRUCE BILTOFT, MEMCOR MAJOR MILESTONES In the past 30 years, Memcor products has played a role in bringing some large-scale water projects to completion. Here’s a look at just a few in their portfolio of more than 2000 processing and treatment plants. 1995: ERARING POWER STATION, LAKE MACQUARIE, NSW The water reclamation plant became the first plant in the world to feature Memcor dual membrane technology. It treats secondary effluent from Dora Creek wastewater treatment plant to then be used for boiler makeup and auxiliary cooling. 2000: AQUA 2000 PROJECT, BENDIGO, VIC The Coliban Water Region Authority commissioned this build-own-operate-transfer project, which included construction and operation over 25 years of a water treatment scheme for the authority in Victoria. The system’s three water treatment plants used Memcor CS micro-filtration technology to deliver water surpassing World Health Organization standards. from 2004 to 2013. The company is now part of the Evoqua Water Technologies family and the sole producer of membranes for its global projects. However, despite Memcor membrane systems international reach and recognition, the company still retains strong ties to its domestic roots. Its products are developed, manufactured and assembled locally at a facility in Windsor, NSW, that employs close to 200 people. “From an Australian viewpoint, it’s the only local manufacturing facility for low-pressure membranes used by municipal and industrial customers,” Handakas said. “Having products that are part of the core water process combined with our design and engineering capabilities means we deliver a complete package.” BUILT TO LAST Part of Memcor products current success and longevity has been thinking outside the box and seeing those ideas through, including turning membranes used in the industrial and medical fields into something more economic. “The majority of applications in the early 1980s were high-value streams where membranes would be disposed of once they had become clogged with contaminants,” said Memcor’s Global Business Development Director Bruce Biltoft. “The key opportunity was to develop a lower cost self-cleaning membrane process that could be applied across a range of applications and flows. In this case the membrane life is measured in years, rather than hours or days.” Since then, Biltoft says flow range has extended by three orders of magnitude, while relative cost per cubic metre treated has reduced by two orders. “It was about scale-up,” he said. “We wrote a lot of the rules on how to apply membranes in [the municipal sector], and that gave us a good idea 2009: GIPPSLAND WATER FACTORY, MARYVALE, VIC This plant proved the technical, environmental and economic viability of Memcor products for industrial and residential wastewater treatment with three primary stages: biological treatment, Memcor membrane ultrafiltration and reverse osmosis. 2011: ADELAIDE DESALINATION PLANT, SA Following years of drought and an exhausted River Murray, the SA Government and SA Water commissioned a large-scale seawater desalination plant. A Memcor products submerged ultrafiltration system was chosen, which was directly coupled to the downstream reverse osmosis system without a break tank. 2016: CLEVELAND BAY WATER PURIFICATION PLANT, TOWNSVILLE CITY COUNCIL, QLD Evoqua was commissioned to supply Memcor membrane filtration technology for the plant. This upgrade will use hollow core membrane systems to contribute to the plant’s hydraulic performance.
