Disinfection

Fluidised Aerobic Bio-Reactor (FAB) as the name indicates consists of floating media of cylindrical shapes and different sizes. As compared to conventional technologies FAB reactors are compact, energy efficient and user friendly.

Basic principle

Flock forming organisms form clusters or attach to available surfaces. The FAB media provides a very large surface area ( 450 M2 per M3 volume ) which

• Increases the specific volumetric capacity of activated sludge tanks
• Controls biomass activity
• Reduces operating cost

The clarified effluent enters into the FAB reactor, which contains the FAB media. The FAB media significantly increases the surface area for bacterial growth. Air is supplied through fine bubble diffusers. Bacteria oxidise the organic matter present in the sewage. Oxidised sewage overflows out of the FAB reactor, into the secondary settling tank.

Advantages using FAB Reactor:

Significant reduction in space requirement due to high surface area & loading rate of FAB media.

Reduced power and operating costs

No sludge recycle required hence no sludge recycle pumps.

FAB Reactor is best suitable when

Designing a new waste water treatment plant, where operating cost & space are constraints .

Upgrading of existing waste water treatment plants.

Operate plants in low temperature areas.

Reduce bulking problems in existing treatment plants.

Applications of FMR

I) Decentralised compact sewage treatment plants for Residential complexes, Hotels / Commercial Center’s / Office Premises / Industries and Rural communities.

II) Industrial wastewater treatment from:

• Food & Beverage
• Textiles
• Pulp & Paper
• Chemicals
• Pharmaceuticals
• Petro-Chemicals
• Dairy Production
