Membrane Bio Reactors (MBR)

Seawater covers 71% of the planet surface and represents 97% of the world’s water, Water Technologies supports municipalities and industries around the world in the implementation of their seawater desalination strategies.

Characteristics

Turbulent flow parallel among the membrane surface
Excellent fouling control results in high flux rates
Efficient and easy clean ability

Reliable and robust process
Optimization of process and membrane – and module design leads to reduced energy consumption.

Biological Treatment

Wastewater enters the bioreactor, where microorganisms (such as bacteria and protozoa) break down organic matter into simpler compounds through biodegradation. This biological process reduces the levels of organic pollutants, nutrients (like nitrogen and phosphorus), and pathogens in the wastewater.

Membrane Filtration

The mixed liquor containing treated wastewater and suspended solids flows through ultrafiltration or microfiltration membranes. These membranes have pore sizes small enough to block suspended solids, microorganisms, and other contaminants, allowing only clean water to pass through.

Solid-Liquid Separation

The membranes effectively separate the treated water from the biomass (activated sludge) and other solids, producing high-quality effluent. The separated solids, known as sludge, are returned to the bioreactor or sent for further treatment or disposal.

Advantages of MBR

1. High Treatment Efficiency

MBR systems can achieve high levels of organic and nutrient removal, producing high-quality effluent suitable for reuse or discharge.
They can effectively remove pathogens and suspended solids, meeting stringent water quality standards.

2. Small Footprint

MBRs are compact and require less space compared to conventional wastewater treatment systems, making them suitable for small or space-constrained areas.

3. Flexibility and Scalability

MBR systems can be easily expanded or modified to accommodate changing wastewater treatment needs, making them versatile for various applications.

4. Reduced Sludge Production

The membrane filtration process results in a higher concentration of solids in the sludge, reducing the overall volume of sludge produced.
The higher quality of the sludge also makes it easier to dewater and dispose of.

5. Improved Effluent Quality

MBRs produce effluent with low turbidity, suspended solids, and pathogens, making it suitable for reuse in non-potable applications or safe discharge into the environment.

6. Resilience to Shock Loads

MBR systems are more resilient to fluctuations in influent flow and composition, making them suitable for treating variable or intermittent wastewater streams.

Suitable for containerized systems

Suitable for containerized systems

1. Municipal Wastewater Treatment

MBRs are used in municipal wastewater treatment plants to produce high-quality effluent for safe discharge into water bodies or for reuse in irrigation or non-potable applications

2. Industrial Wastewater Treatment

MBRs are employed in industries such as food and beverage, pharmaceuticals, and chemicals to treat industrial wastewater and meet regulatory requirements.

3. Water Reuse

MBR effluent can be further treated to meet drinking water standards or used for non-potable applications like irrigation, cooling water, and industrial processes.

4. Decentralized Wastewater Treatment

MBR systems are suitable for decentralized or onsite wastewater treatment in residential, commercial, and remote locations where conventional treatment systems are not feasible.
