The Ballina Shire Council in New South Wales Australia recently completed a $45 million upgrade of their WWTP to a Membrane Bioreactor (MBR) facility. Aquality Water Management worked with engineers and contractors to startup and commission the facility, assist in the development of standard operating procedures and emergency response plans, developed a comprehensive Operations Guide, trained operations in lab procedures and trained staff in the proper operation of the MBR system.
The facility was upgraded from a trickling filter plant and oxidation ditches. In the upgrade the following was constructed;
- A completely new headworks and screening system with flow equalization
- Ultra Violet and sodium hypochlorite disinfection systems
- Aerobic digester
- Sludge handling and dewatering facilities
- New chemical area
- New operations building with a laboratory
- Emergency generators for backup power
- Recycled water tanks
- The MBR system
It was necessary to keep the old system in service while performing the transition to the new system.
Some of the recycled water is being used for residential properties with dual reticulation systems, urban open spaces (parks, golf course, race course etc.) and some commercial systems.
