Technologies - MBBR-IFAS

Moving Bed Bio-Reactor & Integrated Fixed Activated Sludge ( MBBR - IFAS )

DEVISE ENGINEERING S.A. effectively utilizes the so-called MBBR-IFAS process in its packaged “High-Speed Bio-Plants” which are designated for small- and medium-scale biological wastewater treatment applications, both municipal and industrial.
The MBBR-IFAS process has been established in the past 20 years as a simple yet robust, flexible, and compact hybrid technology for wastewater treatment. The term hybrid refers to the fact that the MBBR-IFAS process adopts the best from both suspended and attached growth systems while, at the same time, trying to minimize the deficits of each.
The hybrid nature of the MBBR-IFAS process relies upon the simultaneous incorporation of suspended and attached biomass in the same reactor. The former (i.e. MLSS) is usually kept well below 3000 mg/L, whereas the latter (i.e. biofilm) is established by using specially engineered plastic carrier elements for biofilm attachment held in suspension throughout the reactor by turbulent energy incurred by diffused coarse-bubble aeration, liquid recirculation, or mechanical mixing energy. In the majority of applications, the reactor is filled between one-third and two-thirds full with carriers. Perforated plates or sieves installed on the effluent-end of the reactor allow treated water to pass though to the next treatment step, but retain the media inside the reactor.
The MBBR-IFAS process has demonstrated reproducible success with biochemical oxygen demand (BOD) elimination, ammonia oxidation, and nitrogen removal applications, in a variety of different treatment configurations, aimed to meet a wide range of effluent quality standards, including stringent nutrient limits.

Perhaps the most impressive aspect of the MBBR - IFAS process lies in its versatility, allowing creative solutions by design engineers. Specifically, the MBBR-IFAS process offers the following basic advantages in comparison with other more conventional wastewater treatment technologies:

  • Ability to increase capacity or improve performance by adding more media (high retrofit and/or upgrade potential)
  • Additional biomass for treatment without increasing the solids loading on final clarifiers
  • Higher-rate treatment processes possible, thus resulting to greater treatment in a significantly smaller footprint
  • Development of specialized biomass for carbon and nitrogen removal in multi-compartment reactor configurations
  • Improved settling characteristics (reduced SVI values)
  • Reduced sludge production
  • Improved recovery from process upsets
