New sewage treatment plant for Queensland Council designed to meet environmental plan

Aerofloat worked with a Queensland Council to upgrade its sewage treatment plant (STP) to ensure compliant effluent and a low environmental footprint.

Council called on Aerofloat’s innovative technology to design a STP robust enough to withstand the harsh Queensland weather, whilst also being simple to maintain.

The Need

Ageing infrastructure meant that the existing plant at the regional Queensland site needed a complete overhaul to ensure an ongoing minimal environmental footprint.

The Solution

Given the remote site, the system was fitted with intelligent HMI and remote monitoring capabilities to allow operators access when not on site as well as remote support from Aerofloat’s engineers.

The Benefit

Aerofloat’s engineers designed a MBBR sewage treatment plant that would meet the strict effluent guidelines whilst accommodating future growth at the site.

Background

Australian wastewater and sewage treatment company, Aerofloat, recently worked with a Queensland Council to upgrade its sewage treatment plant (STP) to ensure compliant effluent.

The Council called on Aerofloat’s innovative technology to ensure a system at its regional waste facility that was robust enough to withstand the harsh Queensland weather whilst also being simple to maintain.

The site required an upgrade to ensure ongoing compliancy and a low environmental footprint.

The Aerofloat Solution

Aerofloat designed and constructed a packaged MBBR sewage treatment plant which included an anoxic MBBR fitted with an agitator, three aerobic MBBRs in parallel receiving diffused air through Aerofloat’s proprietary removable diffusers, two secondary clarifiers, a sludge storage and dewatering system, an anoxic recycle pump station and caustic and ACH dosing. Flow is evenly split to the three aerobic MBBRs through a static weir box.

“The static weir box was custom-designed by our engineers for the site”, said Michael Anderson, General Manager at Aerofloat.

“Future growth can be accommodated by simply adding more tanks,” he said.

Aerofloat installed a robust chemical dosing system to condition sludge and assist in sludge dewatering. The entire system was also fitted with HMI and remote monitoring capabilities so that operators can check the plant even when offsite.

“The team on site can call on Aerofloat’s engineers to give advice or make adjustments if required via the remote system,” said Anderson.

The Results

The plant has been installed despite the difficulties raised by pandemic travel restrictions and Queensland floods. The site is on track to be fully operational in early 2022.

Effluent quality is expected to be in line with the Great Barrier Reef 2050 Water Quality Improvement Plan. The Water Quality Plan aims to reduce the amount of nutrients being discharged into the reef from the mainland, to protect and restore the Great Barrier Reef.

Aerofloat has ensured six months of remote support to ensure operators have access to Aerofloat’s expert advice following commissioning of the site.

After Care Service

Aerofloat can help you maintain optimal performance of your wastewater treatment system long after installation.
