FAB

Fluidized 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. Controlled air diffusion FAB based sewage treatment plant works on the principle of attached bacteria growth process supported by specially designed eco-friendly media. This type of treatment depends primarily on the use of air that is introduced into the waste water treatment plant for keeping alive the bacteria. When air diffusion is done, it promotes the growth of organisms that break down the organic solids.

Basic principle:
Flock forming organisms form clusters or attach to available surfaces. The FAB media provides a very large surface area 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 oxidize the organic matter present in the sewage. Oxidized 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.
