Fine screening tech a vital part of wastewater showcase

A prize-winning wastewater treatment plant (WWTP) project in Logan, Queensland, has transformed the surrounding area into an environmental wetland wildlife sanctuary and community recreational asset.

The $116.7 million Cedar Grove Environmental Centre project features what is reported to be the state’s first WWTP to benefit the environment through membrane bioreactor technology and constructed wetlands to achieve record-low nutrient levels and offset remaining nutrients through catchment restoration.

The project has won numerous awards, including the Australian Water Association (AWA) Queensland’s Infrastructure Project Innovation Award.

A key component of the WWTP is CST Wastewater Solutions’ horizontal in-channel rotary drum screening technology, designed as the vital first step in processes to curtail environmental spills, maintenance and associated OH&S issues in WWTPs.

The Ceder Grove wastewater project harnesses CST Wastewater Solutions’ horizontal in-channel rotary drum screening technology.

CST Wastewater Solutions Managing Director Michael Bambridge said the Cedar Grove project has transformed a sewage treatment plant from a type of development attracting community concern to one that has become an outstanding community asset.

“Efficient headworks are vital to all the downstream purification and recycling process stages in a wastewater treatment plant, regardless of the location and input. Unless solids are efficiently separated out from wastewater at the start of the purification process, you are inviting trouble into the system — and this can cost operators dearly in terms of downtime, environmental risk and clean-up costs and OH&S hazards for the teams involved,” Bambridge said.

“We have designed and built our low-maintenance, quality stainless steel technology to provide the simplest but most efficient technology available, proven on multiple MBR plants to perform outstandingly well in the diverse separation tasks of inlet headworks.

“The system is built to be versatile, flexible and robust, because these tasks vary not only from place to place, but day-to-day and week-to-week as loads on the system change.”
