Enzotech – Advanced MBBR Sewage Treatment Process:

Technology- Advanced Moving Bed Biofilm Reactor (Modified MBBR)


Process Description

Treatment Process involved

Bar Screen:

Bar screen is provided to remove the incoming floating solids in the wastewater.

Oil Trap

Oil trap is provided to remove the floating oil from the incoming sewage generated.

Equalization Tank

Equalization tank is provided to collect generated sewage from the source. It is provided to avoid shock loading of sewage to the treatment system due to sudden flow into the aeration tank. Coarse bubble aeration is provided for mixing of sewage in the equalization tank.

MBBR Aeration Tank:

Aeration tank is provided with submerged media and floating media in the tank. Media provides surface area for the attachment of the bacteria. Diffused fine bubble aeration is provided for the transfer of dissolved oxygen for bio chemical oxidation.

Secondary Clarifier:

Secondary clarifier is provided with parallel plates to remove the left out suspended solids present in the secondary treated sewage. Macro-organisms i.e., rotifers and nematodes etc remove floating bacterial debris and fine organic flocs and clean the water very efficiently. This is also an ecologically balanced system and reduces the load on sand and carbon filter considerably.

Intermediate Tank

Intermediate Tank is provided to feed the filter by centrifugal pump. Sodium Hypo Chlorite is dosed as disinfectant for effective disinfection. Extra dosing tank will be provided for treatment of faecal coliform.


Pressure sand filter (PSF) and Activated carbon filter (ACF) is provided to remove the micro suspended solids and dissolved organics present in the secondary treated sewage. After filtration water could be used for Gardening purposes.

Treated water tank

The filtered water from filtration finally enters into the treated water tank. The treated water can be used for gardening, Landscaping or can be let in to river.

Sludge Bed

Sludge drying bed is provided with three compartments to dry generated sludge from the secondary clarifier. Periodical sludge drying is done in the sludge drying bed.

Dried Sludge Disposal

Dried sludge generated from the sludge bed can be used as manure.

Advantages of the Advanced MBBR process:

  • Require 40 to 60% less space than a conventional STP.
  • Minimal chemicals requirement, primarily for initial pH adjustment by lime or Caustic and in the final stage, Disinfection Chemical.
  • Low operation and maintenance cost.
  • Easy installation and easy retrofitting in existing conventional treatment plant. This process not only substantially enhances the capacity of the STP, but also improves the efficiency and thereby the output water quality.
  • Low sludge generation.
  • Flow variation will not affect efficiency of treatment by the STP. The FASTBR plant has considerable buffer capacity.
  • Power consumption is less than conventional treatment plant
  • FASTBR process can be installed successfully in rectangular RCC tank construction structures for large scale sewage plants i.e., in the range of 1MLD and above too. Through FASTBR, the area (foot print) required by these bigger plants is reduced considerably.
  • Moreover this technology can be installed in existing treatment plants (Retrofitting) to improve their performance and the capacity they can handle.
