Wastewater treatment specialists Aerofloat has been awarded the contract for the design and build of a new wastewater treatment plant at Incitec Pivot Limited’s (IPL) facilities at Gibson Island in Brisbane. The project required a comprehensive treatment plant to meet IPL’s strict environmental requirements.

Aerofloat was selected for the project due to its innovative approach towards wastewater system design and its history in ensuring sustainable solutions that meet stringent environmental guidelines. 

“Ensuring solutions are sustainable and environmentally friendly is at the forefront of what we do. As an Australian company, our technology must ultimately support our local environment and community,” says Michael Anderson, General Manager, Aerofloat.

The new wastewater treatment plant at Gibson Island will treat contaminated stormwater and groundwater.

Aerofloat’s wastewater treatment plant will be housed on Gibson Island. There will be no impact on IPL’s operations during the plant’s construction, with IPL able to continue to service its customers as usual.

“Aerofloat’s treatment plant will biologically treat the effluent from the site via its AeroSBR technology, and address any nitrogen, phosphorus, zinc and other contaminants from the site via nitrification, denitrification and clarification processes,” says Michael.

Aerofloat is installing a three-tank biological system that comprises an anoxic reactor and AeroSBR and nitrifying lagoon. Denitrification will take place in the anoxic reactor with the AeroSBR being the final part of the process for further nitrification and clarification.

A multi-media filtration system will further clarify the effluent after the AeroSBR to ensure low suspended solids in the effluent. Aerofloat will be installing a belt press to dewater any excess biosolids prior to disposal offsite.

Aerofloat’s robust chemical dosing system will condition sludge and assist in sludge dewatering.

“The entire system will be fitted with HMI and remote monitoring capabilities,” said Michael.

“Our engineering design team have completed designs and we have begun works on site,” says Michael.

Aerofloat’s wastewater treatment system is scheduled to be operational in early 2024.
