Appropriate to integrate to improve most types of treatment systems.


Cloacina’s Retrofit MEMPAC™ Membrane Bioreactor (RMBR) is designed for clients with existing wastewater treatment equipment that are facing more stringent discharge requirements or who now wish to reclaim their treated effluent. The RMBR treats wastewater using activated sludge with membranes for clarification as the final stage of treatment prior to ultimate disposal. Unlike Activated Sludge treatment plants that utilize a traditional clarifier, membrane treatment does not allow solids to carry over into the waste stream thereby producing significantly cleaner effluent that can be easily reclaimed for irrigation and other purposes.

Modular design allows for easy installation and incorporation into the existing treatment process. The RMBR is provided with all membrane equipment necessary for treatment. All interior and exterior components are made from high-quality, corrosion-resistant materials. All major structural components are manufactured from stainless steel. All internal components are factory-installed prior to delivery. Compact design allows for installations in small and remote locations.
