Package MBR wastewater treatment plant - Prefabricated
Integrated sewage/wastewater treatment system with a combination of
membrane separation and biological sewage treatment.
A package MBR wastewater treatment plant from package
wastewater treatment plant suppliers is a prefabricated module
integrated membrane separation and biological processes or chemical
processes etc. It means minimize set-up and testing at the
site. and simplest the operation. A Typical MBR engineering
process diagram for domestic sewage and municipal wastewater
treatment plant as the following:

Membrane technology has advanced significantly in the past 20 years
for both water purification and wastewater treatment. Today,
membrane-based systems have become the preferred technology for
most of the water purification and wastewater treatment
applications: cod, bod removal, Cryptosporidium and Giardia
control, color or suspended solids removal, etc.
The combination of membranes with the activated sludge process has
redefined the basic sewage & wastewater treatment approach,
optimizing the biological treatment operation and yielding a
treated effluent that is ideal for reuse. Key advances in membrane
technology are at the leading edge of this trend:
Uncoupling HRT and SRT
A significant advantage of the membrane bioreactor process is that
the sludge solids are completely retained in the bioreactor.
This means the solids retention time (SRT) in the bioreactor can be
completely controlled separately from the hydraulic retention time
(HRT).
This is different from the CAS process, where the flocculant solids
that make up the biomass have to be allowed to grow in size to the
point where they can be settled out in the secondary clarifier. In
a CAS, the HRT and SRT are therefore coupled, since the floc size
and thus its settlability relate to the HRT.
High-quality effluent
Membranes pore size (0.03 or 0.1 µm) ensures that the treated
effluent is of very high clarity and significantly reduced pathogen
concentration. MBR processes provide a substantially clarified and
disinfected effluent of high enough quality to be discharged to
sensitive receiving bodies or to be reclaimed for applications such
as urban irrigation, utilities or toilet flushing.
Small footprint
The retention of the solids and the increase in SRT to generate
higher biomass solids concentrations also impacts on the plant
footprint. The increased concentrations mean that the same total
mass of solids is contained in a smaller volume, such that the
footprint is smaller.
Better biotreatment
Lastly, longer solids retention times tend to provide better
biotreatment overall. The conditions encourage the development of
the slower-growing microorganisms, specifically nitrifiers. MBRs
are especially effective at the biological removal of ammonia
(nitrification).
Automatic simplest operation
An STP/WWTP with MBR can be run continuously with a PLC control
system. To get the simplest operation. We have launched a standard
SIEMENS PLC system and SCADA System and SMS alarm etc. You can
control and monitor the system anywhere and anytime only with an
internet service.
Modular Design for minimize/simplest site installation and
operation
All package WWTP/STP is designed with necessary processes base on
different wastewater, like Chemicals reactions, floatation,
sedimentation, biological and membrane bioreactor(MBR), etc. it can
minimize the installation and testing at the site, significant
time-saving.
