Copa MBR Technology®
The Copa MBR Technology® process produces a discharge permeate (water) that can be re-used for toilet cisterns, wash-down, irrigation and more.
The heart of the Copa MBR Technology® is the Kubota flat sheet membrane.
Applications
• For the treatment of a wide range of effluents: sewage; sludge liquors; industrial wastewater; agricultural wastewater; manufacturing and processing wastewater; and, grey-water recycling for a wide range of re-use purposes.
• For any population equivalent (PE) upwards of 50.
• Configurable for installation in concrete or stainless steel tanks; bespoke or retrofit.
• Also available as a compact or containerised unit.
Operation Principle
The basis of Copa MBR Technology® is the Kubota flat sheet membrane; developed as a result of a Japanese Government initiative to produce high quality effluent treatment plants. Copa MBR Technology® is a process that produces a discharge permeate (water) that can be reused for toilet cisterns, wash-down, irrigation and more.
The permeate from the Copa MBR Technology® process is typically:
• < 5:5:5 BOD:SS:ammonia;
• free of pathogens, viruses and bacteria;
• complies with the World Health Organisation standards for Unlimited Irrigation;
• complies with the International Maritime Organisation bacteriological limits;
• complies with the EU Bathing Water Directive.
• compliance with the State of California Water Recycling Criteria (Title 22).
Copa MBR Technology® process employs simple flat sheet membrane panels housed in stainless steel (304 or 316) units and aerated by a coarse bubble system below each unit.
A series of these membranes are submerged within an activated sludge treatment tank. The aeration necessary for treatment of the liquors also generates an upward cross-flow over the membranes; essential to keep fouling of the filtration surface to a minimum. An advantage of this design is that the membrane panels are securely retained and do not touch or abrade each other whilst the units also act as a flume to ensure effective tank mixing and even distribution of the biomass.
