There are several technologies available for sewage treatment today. We shall be focusing on one such widely used sewage treatment process, the sewage treatment plant using MBR technology.
Let us begin by asking a fundamental question:
What is the MBR Technology?
Membrane Bioreactor or MBR Sewage Treatment Plant is an innovative wastewater treatment method. As the name suggests, it combines two technologies, membrane filtration and the biological treatment.
A Brief History of the Membrane Bioreactor
It was first introduced in the later part of the 1960s when microfiltration and ultrafiltration membranes were made available at a commercial scale.
- Dorr-Oliver Inc. was the first to introduce this process.
- In the year 1989, a breakthrough for the MBR was made by Yamamoto and co-workers.
- During the mid-90s, the MBR technology saw an exponential increase in its usage.
Now let us take up the working principle of the MBR.
How Does Membrane Bioreactor Work?
As mentioned before, membrane bioreactor wastewater treatment combines the conventional biological process, i.e., activated sludge, with the membrane filtration technology.
You could say that the membrane bioreactor working principle is all about the ingenious combo of membrane technology and biological treatment.
- In MBR technology system, the semi-permeable membranes, which are two-dimensional materials, (micro and ultrafiltration) are submerged in aerated biological reactors.
- This extent of filtration allows the superior quality of sewage to be drawn through the membranes.
- It also aids in the elimination of sedimentation and filtration processes that are commonly used for wastewater treatment.
- Since the need for sedimentation is removed, the biological process can be operated more effectively.
- A fine screening or pre-treatment is done before the waste enters membrane tank. It helps to protect the membrane and extend its life by minimizing the accumulation of solid wastes.
Features of the MBR Sewage Treatment Plant
The highlights of our MBR Sewage Treatment Plant are as follows:
- Our product features an online backwash system to facilitate smooth operation without any interruptions.
- It can produce a high caliber of treated water.
- It is designed to decrease the associated costs and chemical utilization.
- It does not require a separate settler, clarifier, and polishing units.
- It is flexible in the sense that it can do both underground and above the ground.
- It is eco-friendly.
Membrane Bioreactor Advantages & Disadvantages
Advantages of MBR
- Exhibit high waste removal efficiency.
- Better effluent quality.
- Ability to remove several contaminants like bacteria, nitrogen, and other suspended solid wastes.
- Occupy less space which means small footprint.
- It produces less volume of sludge.
Disadvantages of Membrane Bioreactors
- Require a substantial amount of capital investment.
- High energy costs.
- Maintenance cost could be higher due to membrane replacement.
- Additional chemicals may be needed according to the requirements.
- It requires trained professionals for its operation.
Applications of Membrane Bioreactor
Membrane bioreactors have several applications:
- Automobile industries
- Oil & gas companies
- Fertilizer & solvent extractors
- Iron & steel industries
- Pharma industry
- Petroleum refinery
- Dye & chemicals unit
- Pulp & paper industry
