To begin with, wastewater treatment is no longer a luxury. Secondly, it is a necessity that no business can refrain from. Apart from the ability to reuse the water, it has become an important part of compliance and sustainability initiatives.

It was the loop holes in the efficiency of the traditional wastewater management techniques that led to emergence of new technologies. The latest membrane technologies India have witnessed revolution in the form of Membrane Bio Reactor System.

Now, in this blog, we will discuss about what is hollow fiber membrane technology and how they are successfully changing the face of wastewater treatment.

What is Membrane Bio Reactor System – MBR?

A membrane bio reactor is an advanced system designed for wastewater management in an efficient manner. The technique is an amalgamation of biological treatment with membrane filtration.

The conventional methods relied on sedimentation for separation of solid from liquid. However, membrane technology uses semi- permeable membranes. It offers excellent filtration outcome suitable for industrial reuse.

Key Features:

Removes bacteria, viruses, and suspended solids.

No need for secondary filtration.

Highly pure water suitable for industrial usage.

Lesser risk of operational issues/ system failures.

Components of Membrane Bio Reactor – MBR

Biological Treatment Unit

The section acts a traditional activated sludge process.

Microorganisms breakdown the pollutants and organic matter.

Oxygen is supplied to enable microbial activity.

Bacteria degrade the contaminants efficiently.

Membrane Filtration Unit

Membrane Bio reactor is the core component.

Efficient membranes separate treated water from the sludge.

Membranes are made of Polytetrafluroethylene/ Polyvinylidene fluoride/ Polyethersulfone.

Pre- Treatment

Wastewater is processed for removal of sand, grease, and large debris. It is a crucial step to prevent logging the membranes and prolonging their lifespan.

Biological Degradation

Wastewater enters the bioreactor- microorganisms and bacteria breakdown organic pollutants. The aeration system takes care of the oxygen supply. This promotes microbial growth and efficient pollutant removal.

Membrane Filtration

After the biological treatment, the mixture enters the membrane modules. Membranes become the physical barrier and retain pathogens, solids, and bacteria. It allows only clean water through it.

Effluent Reuse

The filtered water received complies with the stringent standards. The water is safe enough to be released into the environment. It is safe to agricultural and industrial use as well.
