Technology of MBR domestic wastewater treatment
Date public: 20-06-2024||View: 4602
In the context of rapid modernization and industrialization, development has laid the groundwork for economic growth. The focus on water usage has created polluted wastewater, which requires suitable treatment technologies like MBR, MBBR, SBR, etc. This article aims to provide you with basic concepts about MBR technology, hoping that you can choose the right method for your wastewater source.
1. What is the Purpose of MBR Membrane Filtration in Wastewater Treatment?
MBR wastewater treatment technology is a combination of activated sludge and MBR membrane filtration. MBR stands for Membrane Bioreactor, which is considered a wastewater treatment technology that combines biological and physical methods to produce treated wastewater that meets current standards.
The membrane filters out suspended solids and other solid materials present in the wastewater. The application of MBR wastewater treatment technology results in discharge water that meets standards and can even be reused.

2. How Does the Wastewater Treatment System with MBR Membrane Work?
The membrane surface retains solid waste, allowing clean wastewater to pass through, while the retained sludge is collected periodically. The presence of an air blower helps to regulate the water flow and prevent clogging of the MBR membrane surface.
2.1 Why is the MBR Membrane Said to Have Many Advantages?
According to practical evidence, the application of MBR wastewater treatment technology brings commendable results:
-
Treatment efficiency increases by 10-30%.
-
Reduces construction and installation costs.
-
Water retention time is 2.5 - 5 hours.
-
High microorganism concentration limits sludge generation and increases the efficiency of activated sludge.
-
The treated wastewater has very low solid content and can be reused.
-
Applicable to various anaerobic, anoxic, and aerobic tanks.
2.2 How Does MBR Wastewater Treatment Technology Work?
A typical treatment process includes:
In contrast, the MBR tank combines both processes of bacterial separation using membrane filtration and waste decomposition.
Current MBR systems typically come in two forms:
-
Submerged MBR in the reaction tank, which can be removed for cleaning using pressure.
-
Placed outside the reaction tank in the MBR wastewater treatment system, which can be cleaned with air or by backwashing with water and chemicals.
Waste treatment in the wastewater helps to design the system without relying on sludge formation or separation capacity but solely on MBR membrane filtration. However, one of the considerations when using MBR wastewater treatment technology is the potential for membrane clogging. Therefore, if you need support to ensure smooth operation, you should contact Dai Nam engineers so that we can help you clean the membrane as soon as possible.
Typically, MBR membranes become clogged due to the following reasons:
