Future-Proofing Leachate Management at Brisbane’s Rochedale Landfill
CASE STUDY Design, construction and commissioning of a biological leachate treatment plant built for long-term compliance and closure planning The Need Aerofloat was engaged to
Aerofloat installed an automated pH correction system that monitors temperature and pH prior to discharge.
Aerofloat’s outstanding customer service led to Fyna Foods contracting its chemical supply through Aerofloat.
System automation from Aerofloat helped the confectionery manufacturer to remain compliant.
Its trade waste system was paired with an antiquated pH testing system that regularly needed probe replacement and checking. It was also hard for staff to ascertain the actual pH of wastewater at discharge, which would have serious implications for the business should the levels be outside of the company’s trade waste agreement.

“Aerofloat’s cost-effective treatment options appealed to our business and size of operation. The team was excellent in assisting Fyna with several options that would ensure compliance to our trade waste agreement. Understanding the regulations isn’t easy if you don’t specialise in the area so I was grateful to Aerofloat’s Managing Director, Ray Anderson, for his patience with my questions over the journey from quote to commencement of the installation.”
Aerofloat’s pH correction equipment featured an automated correction system that allowed operational staff to monitor the temperature and pH levels, prior to discharge.
“Understanding the wastewater impurities, the placement of wastewater systems and production controls was integral to setting up an automated pH correction system at Fyna,” says Anderson. “We needed to create a product that would allow Fyna to operate year-round, regardless of outside temperatures and production variations, with the guarantee that the wastewater pH at discharge would be well within the local guidelines.”

Following the installation of the wastewater system at Fyna, the company contracted Aerofloat to provide ongoing chemical supply. “We order our chemicals for the system from Aerofloat and its service has been excellent – our previous supplier still hasn’t answered an email for a quote for the acid we needed,” said Powell.
