Box Hill Water’s processes meet strict Australian Guidelines for Water Recycling. Wastewater undergoes seven extensive filtration and purification processes including Membrane Bioreactor (MBR) and Ultraviolet (UV).
- Wastewater screening
- Anaerobic processing
- Aerobic processing
- Chemical treatment
- Membrane filter
- Ultraviolet disinfection
Plastics and rubbish are taken out of the wastewater
After the wastewater is screened it enters the biological processing tank bioreactor for anaerobic processing. Natural bugs break down the wastewater.
Air is added to the wastewater, creating new bugs which continue the break down process.
Four chemicals - Sodium Hydroxide, Sodium Hypochlorite, Aluminium Sulphate and Acetic Acid - are added at different stages to balance and disinfect.
The wastewater is sucked through microscopic membranes that block out bugs - removing bacteria, pathogens and other impurities.
Water goes through the Ultraviolet disinfection process neutralising any remaining impurities.
Chlorine is added to the water for the final purification process.
