Membrane bioreactor and screening technology for Goulburn sewage treatment plant

As part of its upgrade to the Goulburn sewage treatment plant (STP), Haslin Constructions is including a membrane bioreactor (MBR) process that will produce a high-quality effluent for re-use for irrigation on sporting fields and parklands.

Screening technology from Hydroflux Huber will meanwhile be installed to protect the membrane bioreactor modules which are central to the plant’s process. HUBER’s RPPS ROTAMAT inclined drum screens are the core of this screening technology, having been used in pre-MBR screening applications throughout Australia and around the world.

“The HUBER RPPS ROTAMAT protects the membranes from accumulation of fine fibrous material and screenings that can pass through even the finest inlet screens,” said John Koumoukelis, director of Hydroflux.

“We use a 2 mm perforated drum, which allows for exceptional capture rates of fibres. A heavy-duty PU seal ensures no bypass of flow.

“The HUBER ROTAMAT design includes the integrated washing and compacting screw, meaning that only one drive is required for this unit. The entire machine is fabricated in 316 stainless steel and built to the highest German standards.”

The upgrade will ensure sewer discharge from the Goulburn STP meets modern-day environmental standards and that the plant is able to cope with future population growth.
