Containerized small package sewage treatment plant for irrigation
Membrane Bioreactors have been used for the successful treatment of
municipal, commercial and industrial wastewaters for discharge and
reuse since the 1980s. Membranes physically reject pathogens and
other suspended solids, producing an extremely high quality
Containerized plant, takes advantage of the compact nature of the
MBR system, and can be used as either temporary or permanent
solutions, or as pilot plants for high strength industrial
applications. The containerized plants can treat low strength
municipal waste or high strength industrial effluent. The plant has
a small footprint and is simple to set up, connect to a power
supply and begin treatment of wastewaters. Finance and leasing
options are available.
Despite its simplicity, extremely high levels of treatment are
achievable, with both the Membrane Bioreactor (MBR) and Submerged
Aerated Filter (SAF) reducing the risk of water-borne disease and
nuisance odours. Conveniently supplied in trace-heated and lagged
20’ ISO containers, complete protection is provided across
environments from -56°C to +58°C. The package design includes all
associated ancillary equipment such as pumping stations, pipe-work,
valves and fittings. The containerized MBR package is capable of
providing a Grade 2 water quality discharge which is suitable for
reuse, wash-down or irrigation. Non-containerized tanks incorporate
lifting points for easy loading and off-loading from flat bed
transporters, and are sized for C130 aircraft.
How it works?
The membrane bioreactor (MBR) receives raw effluent via an inlet
pump to a fine screen. Screened influent then moves to the membrane
tank. Treatment occurs via a submerged membrane filtration process
within the activated sludge.
Aeration serves to oxidize BOD (Biochemical Oxygen Demand) and
ammonia and produces a cross-flow across the membrane surfaces to
minimize membrane fouling. Fine bubble aeration diffusers can also
add extra oxygen that may be required with stronger loaded wastes
such as industrial effluent.
Permeate passes through the membranes via a header, with flow
controlled by an automated modulating valve. A pressure transducer
on the permeate line calculates the differential pressure necessary
to achieve required flows. This data can be used to initiate a
pre-emptive chemical clean of the membranes. Chemical cleaning is
normally carried out every six months.
A flow meter records current and total permeate flow. Overflows are
provided on the screening unit and within the MBR tank.
