Membrane Bio Reactor (MBR)
Aquatec-Maxcon is the exclusive agent for Kubota membrane bioreactors (MBRs) modules in Australia and New Zealand. Our company designed and constructed the first commercial scale MBR in Australasia for Townsville CitiWater at Picnic Bay, Magnetic Island. The project received an Engineering Excellence Award in 2003 demonstrating its state of the art technology and capability.
The development of the submerged membrane bioreactor technology by Kubota was the result of a Japanese Government initiative to produce compact high quality effluent treatment plants. Kubota, since producing their first pilot plant in 1989 and first commercial plant in 1991 have installed over 1,700 plants treating a wide range of effluents including sewage, sludge liquors, industrial and food processing wastewater and grey water recycling for re-use.
The Kubota system utilises a flat sheet membrane panel arrangement. A series of these membranes are submerged directly within an activated sludge treatment tank, greatly simplifying the overall plant layout and provide a directly micro-filtered product water. By this configuration, the energy required for aeration of the treatment liquor also generates an upward cross flow over the membranes, keeping fouling of the filtration surface to a minimum.
The membrane bioreactor treatment produces a high quality disinfected effluent. The process requires no primary or secondary settlement stages and no additional tertiary treatment or UV stages to achieve disinfection suitable for many applications. Raw sewage only requires screening and degritting prior to entering the membrane bioreactor tank and subsequent discharge.
Kubota MBR Applications:
• Suitable for Class A Reuse.
• Suitable as a pre-treatment for Reverse Osmosis applications.
• Compact Wastewater Treatments for Developments for Irrigation, and Non-Potable Reuse.
• Suitable Treatment Process to meet discharge requirements for Marine Life, Bathing Sites, etc.
• Retrofit into existing Wastewater Plants for increased Plant Capacity and better effluent quality.
• Industrial Wastewater applications such as brewery, beverage pulp and paper, and food wastewater.
