MBR Working Principle

Membrane filtration has a major role in water and wastewater treatment, which is superior to the conventional water technologies with a proven better performance and more efficient economics.

The basic membrane processes are microfiltration (MF), ultrafiltration (UF), nanofiltration (NF), reverse osmosis (RO).

Separation ranges for those membranes are as follows: 100 to 1000 nm for MF, 5 to 100 nm for UF, 1 to 5 nm for NF, and 0.1 to 1 nm for RO.

For more than the last 10 years MBRs have emerged as an effective secondary treatment technology by using membranes in the range of MF and UF.

MBR Working Principle
A Membrane bioreactor (MBR) processes are mainly used for wastewater treatment (WWT) by using microfiltration (MF) or ultrafiltration (UF) and integrating them with a biological process like a suspended growth bioreactor.

The membranes are employed as a filter removing the solids which are developed during the biological process, which gives a clear and pathogen free product. A visual example can be found from the following picture of an immersed MBR (iMBR) in Figure 2.

MBR Working Principle
Fig.2 The wastewater goes through a fine screen for the removal of big objects that might cause damage to the downstream equipment. Then it enters an Anoxic Zone for the treatment of nitrogenous matter and phosphate following an Aerobic Zone where microorganisms with the help of the oxygen coming out of the FBD will digest the organics matter in the wastewater and clump together as they do so, producing a sludge. This sludge will enter the Immersed Membrane Bioreactor where the membrane will separate  the solids and microorganisms from water.

A membrane bioreactor is essentially a replacement in the conventional activated sludge (CAS) system for the settlement tank for solid/liquid separation. The MBR gives to the end user improved process control and much better product water quality.

The MBR process operates over a considerably different range of parameters than the conventional activated sludge process

· SRT 5 -20 days for conventional system - 20 -30 days for MBR

· F/M 0.05 -1.5 d-1for conventional system - < 0.1 d-1for MBR

In general MBRs have three distinct membrane configurations (Fig.3),

1. Hollow fibre (HF)

2. Multitube (MT)

3. Flat sheet (FS)

membrane configurations

This PTFE hollow fiber MBR membrane which made by Sumitomo is fantastic. It can be used in industrial swege water, desalination pretreatment,oily wastewater, high concentration organic wastewater, high viscosity wastewater treatment. We have one client who used this kind membrane for 9 years. It is very qualified.

MBR Applications

When MBR is your first choice ?

1. Limited space or you want to use space efficiently.

2. End user requires high quality treated water(e.g. for water reuse)

Although the MBR global market is mainly dominated by a few major companies, the number of technology suppliers continues to grow, with over 70 MBR membrane module products available on the market today.

In general MBRs have been applied to treat effluent in a number of industrial sectors, like: and beverage − high in organic loading

2.petroleum industry − exploration, refining and petrochemical sectors

3.pharmaceutical  industry – have active pharmaceutical ingredients (APIs)

4.pulp and paper industry − high levels of suspended solids, COD and BOD

5.textile industry effluent − re-biodegradability, toxicity, FOG content and color

6.landfill leachate − wide variety of dissolved and suspended organic and inorganic compounds

7.ship effluents − legislative requirements and space restrictions.

8.Industrial versus municipal treatment
