Membrane Biological Reactor Wastewater Treatment Mbr Of Non Drinking Water

MBR System for Reuse of Non-drinking Water DEM80-100

Introduction to Membrane Technology

Types of Membrane Processes:
There are various membrane processes employed in different applications. Some common membrane processes include:

Microfiltration (MF): Microfiltration membranes have larger pore sizes, typically in the range of 0.1 to 10 micrometers. They are used for separating suspended solids, bacteria, and large particles from liquids.

Ultrafiltration (UF): Ultrafiltration membranes have smaller pore sizes, typically ranging from 0.001 to 0.1 micrometers. They remove smaller particles, colloids, macromolecules, and some viruses from liquids.​

Material Advantage

Good Quality Effluent: MBR systems produce high-quality effluent with low turbidity, suspended solids, and organic content. The membrane acts as a physical barrier, preventing the passage of solids and bacteria into the treated effluent. This is particularly advantageous for discharge to sensitive receiving waters or for reuse applications.

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 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.
