Aerofloat constructing new wastewater treatment plant
Wastewater treatment specialist Aerofloat has been awarded the contract to design and build a 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 history in creating sustainable solutions that meet stringent environmental guidelines and its innovative approach towards wastewater system design.
Michael Anderson, Aerofloat General Manager, said, “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.”
The plant will treat contaminated stormwater and groundwater. It will be housed at Gibson Island and there will be no impact on IPL’s operations during its construction.
According to Anderson, it will biologically treat the effluent from the site using its AeroSBR technology and address nitrogen, phosphorus, zinc and other contaminants from the site via nitrification, denitrification and clarification processes.
Aerofloat will install a three-tank biological system comprising an anoxic reactor, 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 chemical dosing system will condition sludge and assist in sludge dewatering.
“The entire system will be fitted with HMI and remote monitoring capabilities,” Anderson said. “Our engineering design team have completed designs and we have begun works onsite.”
Aerofloat’s wastewater treatment system is scheduled to be operational in early 2024.
