WarraniumMBR - Membrane Bioreactor
The treatment of sewage has advanced greatly in terms of the
quality of the treated effluent and minimising the footprint of
the process and the WarraniumMBR membrane bioreactor - or
MBR - is an example of this.
The membrane is in the Ultra to Micro Filtration range
meaning that it acts as a barrier to bacteria, coliform,
cryptosporidium and some viruses. And it will reject
suspended solids greater in size than around 0.1 microns. It is,
therefore, an excellent technology for clarifying biologically
treated water that has a high biomass concentration. Just as in
the activated sludge process, the MBR plant uses an aeration
tank where the beneficial biomass consumes the organic
matter in the sewage.
But the treatment is performed using a membrane instead of a
traditional settlement tank. The WarraniumMBR plant goes
further still and performs both tertiary treatment and
disinfection of the treated effluent. This water is suitable for
'un-restricted' irrigation such as lawn sprinklers. For clients
requiring potable quality water, this can be achieved by
further treating the WarraniumMBR water with reverse
osmosis (RO) membranes. This water can then be used for
many tasks where potable quality water is needed. Warranium
Energy design and manufacture the WarraniumMBR
membrane bioreactor in capacities of 5000 - 50,000 m3 per
day. The smaller plants are packaged type, often containerised
for easy shipping and use epoxy coated steel tanks. These are
factory built and tested prior to despatch. The larger
WarraniumMBR plants are constructed, for the economy, on-
site using either bolted, steel panel tanks or reinforced
concrete tanks.
