Membrane Biological Reactor Wastewater Treatment Mbr Of Non Drinking Water

Product Specification

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.
