Dynamic MBR Membrane Bioreactor For Wastewater Treatment Municipal

Heat-Resistant Membrane Bio-Reactor for Municipal Water Reuse DEM80-80

Introduction to Membrane Technology

Principle of Membrane Separation:
Membrane separation relies on the principle of selectively allowing certain molecules or particles to pass through a membrane while retaining others. The semi-permeable membranes used in this process have tiny pores or channels that enable the passage of specific components based on their size, charge, or other properties. This separation mechanism allows for the purification, concentration, or fractionation of substances within a mixture.​

Material Advantage

Chemical Resistance: The membrane material used in MBR systems is resistant to chemicals, including chlorine and other disinfectants. This makes them suitable for applications where chemical disinfection is required.

Higher Heat-resistance Ozone-depleted Antimicrobial Preservative

Features

1. Space saving: Compared with the traditional model, it only
occupies one-third of the original area.
2. Low energy consumption: lower wind pressure can be used for
oxygenation, compared with other traditional treatment processes,
the power consumption is greatly reduced.
3. Low maintenance cost: the automatic control can be started with
one button to realize unattended operation, and remote monitoring
can be realized through the mobile phone APP.
4. Long service life: no human daily maintenance is required, and
the service life is more than 10 years.

APPLICATION

Due to the presence of MBR greatly improving the solid-liquid
separation ability of the system, microorganisms are completely
retained in the bioreactor, eliminating the problem of sludge
expansion in traditional activated sludge. As a highly efficient
water treatment technology, membrane bioreactor has been widely
used in all kinds of domestic sewage, municipal sewage, organic
industrial wastewater treatment and water reuse banning fields,
effectively improving the sludge age of activated sludge growth.

COMPONENT

DEM series flat MBR membrane modules are composed of a membrane
element box and aeration box, in which the membrane element box is
composed of membrane element, water-producing silicone hose, ABS
water collection pipe, chute (fixed membrane element) and stainless
steel bracket.


The aeration box is composed of UPVC main pipe, ABS aeration branch
pipe, pipe flange and stainless steel bracket.









Attention:


1. The membrane module is set in the membrane tank, and the treated
water filtered by the membrane element is discharged through the
hose and collecting pipe.


2. In order to prevent the pollution of the membrane element, the
lower part of the membrane module is equipped with a perforated
aeration pipe, which produces an aeration flow that can provide
oxygen for the biological reaction of the aerobic tank and clean
the surface of the membrane element at the same time.


3. SUS304 stainless steel is generally used as the material of
membrane module support, if used for sewage containing high
concentrations of chloride ions or other salts, please specify when
ordering, so that the membrane module support can be made of the
material suitable for it.

MBR Process Flow

Sewage flows through the mechanical grating (grating gap less than
1mm) to capture large particles of suspended solids and impurities
and then flows into the sewage regulating tank for water quality
and water quantity adjustment, and then lifted by the lifting pump
to the MBR biological reaction system. The whole biochemical
treatment system consists of a pre-treatment tank and MBR reaction
tank, according to the incoming water quality and effluent
requirements, to determine whether the need for the pre-treatment
tank. The pretreatment tank can adopt hydrolysis acidification, an
anaerobic or aerobic process, or an anoxic denitrification tank.
MBR reaction tank is equipped with a submerged flat membrane
module, constituting MBR- aerobic operation mode.


MBR reaction pool effluent directly into the reuse pool, adding
disinfectant or ultraviolet light disinfection, the effluent
discharge or pumped into the water pipeline network through the
reuse, but also for nanofiltration or reverse osmosis system for
further treatment and reuse.
