Waterworks’ Membrane Bioreactor (MBR) systems applies the best technology and installations around the world to a variety of locations. Waterworks can supply pre-packaged systems or systems that meet with specific client needs. Designs can be “hollow fiber” based or “sheet” based membrane type. Also it can be provided as a skid mounted or containerized units.
Advantages of MBR Systems
The advantages of MBR include:
Secondary clarifiers and tertiary filtration processes are eliminated, thereby reducing plant footprint. In certain instances, footprint can be further reduced because other process units such as digesters or UV disinfection can also be eliminated or minimized.
Unlike secondary clarifiers, the quality of solids separation is not dependent on the mixed liquor suspended solids concentration
or characteristics. Since elevated mixed liquor concentrations are possible, the aeration basin volume can be reduced, further
reducing the plant footprint operation and also to prolong the lifetime of the membranes.
Produces a MF/UF quality effluent suitable for reuse applications or as a high quality feed water source for reverse osmosis treatment. Indicative output quality of MF/UF systems include SS 1mg/L, turbidity 0.2 NTU and up to 4 log removal of virus (depending on the membrane nominal pore size).
In addition, MF/UF provides a barrier to certain chlorine resistant pathogens such as Cryptosporidium and Giardia.
The small footprint can be a feature used to address issues of visual amenity, noise and odors.
Some of the main influences for the increasing interest in MBR technology include:
