Addressing Australia’s wastewater

Wine, beverage and food makers will seek on-site effluent treatment as drought goes on and standards toughen.

Wastewater has become a critical issue in the wine, beverage and food manufacturing industries as water increases in value and effluent standards become ever more stringent.

“The ongoing drought in many wine and food growing areas is encouraging water recycling.

At the same time, producers are facing financial incentives to upgrade the quality of used water they discharge into sewers or put back into the soil,” said CST Wastewater Solutions managing director, Michael Bambridge.

The company is anticipating a rising demand for wastewater treatment plants that are tailored to the specific needs of the beverage and food industries.

CST’s Smith & Loveless effluent treatment plants are already installed in overseas wineries, such as in the Napa Valley in California, and Bambridge forecasts that Australia’s producers will soon follow.

“With a fully professional treatment system in place, wine and food manufacturers can recycle as much as possible of their wastewater, meeting tough effluent standards and reducing their water bills,” he said.

For more than two decades, CST Wastewater Solutions has been installing effluent purification systems in Australia and NZ industry, solving problems associated with seasonal production peaks, groundwater seepage, septic overloads and stringent permit regulations.

CST Wastewater Solutions supplies three major types of on-site effluent treatment systems for food producers, designed to handle large, medium or small wastewater flows.

  • For corporate and large production wineries and food manufacturers, the Model R OXIGEST provides a complete wastewater system with concentric tankage. This extended aeration system is designed for flows from 375 cubic metres per day (cmd) to 11,000-plus cmd.
  • For system flows of 20-11,000-plus cmd, the award-winning TITAN MBR is a complete membrane bioreactor (MBR) tailored to the wastewater issues facing the wine, beverage and food manufacturing industries. It delivers the highest quality effluent for these applications.

    TITAN MBR utilises flat plate membranes for the simplest operation and maintenance in MBR technology. The membranes eliminate the need for a clarifier and for tertiary filtration.

  • FAST (Fixed Activated Sludge Treatment) is ideal for winery and food manufacturing effluent from 20 to 375 cmd. It employs patented fixed-film media to cope with seasonal or variable flows, maintaining stable operation while minimising space use and maintenance requirements.

    Smaller, modular FAST systems can be buried in the ground, for both convenience and aesthetics.

FAST and TITAN systems are a continuing evolution of prefabricated and portable wastewater treatment plants that Smith & Loveless pioneered in Australia and around the world some decades ago.

Both are activated sludge treatment systems that provide the benefits of modular design and construction, low sludge production, few moving parts, low maintenance and systemic robustness.

These systems are now proven in hundreds of Australasian installations, ranging from municipal and private developments to industrial and commercial sectors, as well as specialised marine use.

CST Wastewater Solutions has been providing a broad range of industrial and municipal water and wastewater solutions for 25 years.

CST Wastewater Solutions is a member of the Global Water and Energy Alliance, a group of select companies around the world committed to providing solutions in waste and wastewater treatment for the recovery of green energy and water.

The company’s robust network of partners includes Smith & Loveless, one of the world’s most respected water and wastewater pumping and treatment organizations, and Berson UV-techniek, world leaders in UV disinfection for water reuse.
