Hydroflux HyDAF Installation at Burra Foods for Enhanced Efficiency and Reduced Energy Consumption
Hydroflux Industrial supplied, installed and commissioned a Hydroflux HyDAF HD -75 at Burra Foods in their existing Korumburra treatment plant located in the South Gippsland Region of Victoria, for the purpose of increasing the efficiency of the existing wastewater treatment plant.
The original wastewater treatment plant split the incoming effluent into two separate tanks, one for high solids, the other for low solids. The low solids effluent was then fed to the Sequencing Batch Reactors (SBR’s) tanks, whilst the high solids was bled in a reduced rate. The downside of the high solids feed direct to the SBR’s, even at a reduced rate, is increased the loading in the SBR, requiring a significant oxygen volume for the process
With the HyDAF was installed as a primary treatment process, the high solid effluent is fed from the storage tank to the DAF via a pre-reaction tank for acid cracking of the oils, grease and fats, at a low pH (approx. 4.6), polymer is also injected at the DAF entrance. Once the DAF has removed the milk solids, oils, grease & fats, the clarified effluent is then pH corrected to 7 with caustic in a post reaction tank, before being pumped to the low solids tank.
With the removal of much of the solids load the SBR’s, could operate at a reduced need for oxygen, with the site noting that the required energy consumption started to drop within a week of DAF’s commencing operation. Over the following months with some additional fine tuning the energy consumption was reduced to almost half, as well increasing the through of the SBR’s.
Hydroflux Industrial not only provided the DAF unit but also all other associated equipment including the pre & post reaction tanks complete with mixers, chemical dosing pump and pH controllers, as well as turbidity monitoring in the discharge tank. All equipment controlled and monitored via the Hydroflux supplied MCC.
