A simple pH system design ensured compliance with strict council wastewater regulations.

When a brewery needed a pH correction system to meet strict council guidelines, it turned to Aerofloat.

The Need

In order to address the strict wastewater requirements of Dubbo Regional Council, the team at Devil’s Hollow Brewery found they needed a pH correction system to suit their specific needs.

The Solution

Aerofloat engineers were able to quickly understand the needs of the client and provide a simple pH correction system to meet discharge regulations.

The Benefit

After visiting the Aerofloat plant at 4 Pines Brewery in Brookvale and being recommended to work with Aerofloat by the team there, Devil’s Hollow had a fit-for purpose Aerofloat pH correction system installed – ensuring they met strict council standards.


Devil’s Hollow Brewery is a highlight on any visitor to Dubbo’s itinerary -being the largest craft brewery in the Dubbo area.

CEO and General Manager, Brendon O’Sullivan values the voice of the brewing community around Australia. “The craft beer community is outstanding. We’ve had support and ideas from every brewery we’ve spoken to, from Queensland to New South Wales and down to Victoria. We feel really lucky to have been recommended to work with Aerofloat,” he said.

As a start-up microbrewery, Devil’s Hollow did not require a full wastewater treatment plant.  Therefore, Aerofloat installed a fit-for-purpose pH correction system, specially designed by Aerofloat engineers for the microbrewery industry.

The Aerofloat Solution

Brendon O’Sullivan, CEO and General Manager for Devil’s Hollow, was recommended by 4 Pines Brewery to get in touch with Aerofloat.

“Aerofloat was easy to talk to and very experienced – the team really knew what our requirements were despite us being in such a niche market. Aerofloat was able to build a system to specifically suit our needs and space.”

Aerofloat installed a pH correction system to ensure compliant outgoing wastewater. The system included a 2,500L tank complete with a collection pit transfer pump and an inline solids filter, mixing pump, pH monitor, chemical dosing pumps and flow meter.

“The area we had to work with was pretty tight – around 2.5 x 1.5 metres. The system was built to fit the site perfectly,” said Aerofloat’s Operation’s Manager, Tim McCann.

“This particular system was unique as we designed it to be transportable using a standard sized ute,” said McCann. “This kept transport costs from Sydney to Dubbo at an absolute minimum and allowed us to arrive on-site with the system as soon as Devil’s Hollow were ready for installation.”

The system also included a remotely viewable data logger, meaning the pH data and discharge flow rates were continually recorded. By providing an automated system instrumentation, Devil’s Hollow staff were able to monitor and predict pH over time. It also ensured that the system was under constant surveillance, with 24-hour monitoring in place. Devil’s Hollow staff are alerted automatically when any unusual activity arises, allowing them to focus on other tasks.

“Our local council requires us to provide monthly reports on wastewater effluent – the automated system means we can meet our commitment to that,” said O’Sullivan.


The brewery officially opened to the public in July 2019.

“We needed our pH correction system in place in time for production – Aerofloat ensured that we met that deadline, on budget,” said O’Sullivan.

“Aerofloat built the system in a few days, and the installation took less than a day. A couple of walk-through lessons with the Aerofloat engineers following installation, and we were ready to go,” said O’Sullivan.

Aerofloat have given expert advice to the team as needed and the pH correction system is working effectively.
