Sydney brewer 4 Pines recently opted for Aerofloat’s compact, low maintenance and completely sealed DAF as part of its brewery expansion.

Sydney brewer 4 Pines has embarked on a new growth strategy following its acquisition in September last year by global alcohol giant, AB InBev.

The capital injection enabled 4 Pines to expand its operations, starting with an upgrade to its Brookvale brewery in order to increase production by up to 50 per cent.

A key component of this was to ensure its systems adhered to environmental standards. Sydney Water has strict compliance guidelines around wastewater from breweries, stipulating the acceptable pH range and the concentration of suspended solids before it is discharged to sewer.

Ensuring its Brookvale facility met Sydney Water’s discharge requirements was essential.

However, the available space provided a challenge for wastewater treatment: there was only a small 15m2 footprint available and the area was next to the public bar where food and beer is served. The brewery needed a wastewater system to remove the solids from the wastewater and correct the pH before discharging to the sewer.

Dissolved Air Flotation (DAF) was the desired technology of choice, but traditional DAFs required twice the available space and emitted odours from their open top tanks, not a great option considering its close proximity to diners.

4 Pines looked to Aerofloat to provide a solution given the company’s expertise in food and beverage wastewater treatment. Aerofloat have provided a custom wastewater solution for 4 Pines based on its patented DAF technology, which has a completely different design to traditional DAFs.
