S&L MBBR-iFAS

Smith & Loveless developed the packaged treatment concept more than 60 years, and continues to develop innovative system designs tailored to meet these essential goals: (1) deliver systems that meet or exceed customer effluent requirements (2) deliver systems that maximize the ease and cost of installation, operation and maintenance (3) minimize footprint requirements.

S&L MBBR-iFAS fixed-film (attached growth) packaged treatment systems meet all three of these goals. S&L packaged MBBR-iFAS systems provide all of the advantages of a conventional MBBR system, in a prefabricated tank package. Design to essentially “plug & play”, the technology is easy to install for customers with urgent and specific treatment system needs, and it reduces the tanks size and footprint.

Benefits vs Conventional Biological Treatment Systems:

  • Reduced footprint
  • Enhanced process stability
  • Better handling of variations in flow, temperature, and other influent quality
  • Resistant to shock loads
  • Incremental capacity within the same basin by adding more media

Product Details

Biofilm Effective Surface Area Makes the Difference

S&L’s Moving Bed Biofilm Reactor (MBBR-iFAS) systems utilize innovative biofilm carriers operating in mixed motion within an aerated wastewater treatment basin. A very dense population of bacteria attachment and growth achieves high-rate bio-degradation within the system, and its self-regulating nature responds superbly to toxic shocks and variables loads.

In normal conditions, the effective surface area of the S&L biofilm media allows for significantly smaller tankage and system footprint, which lowers capital and operating costs. 

 

Process Flexibility to Meet Tailored Requirements

To achieve specific effluent and/or smaller footprint requirements for individual municipal and industrial-commercial application, Smith & Loveless treatment systems are converted to MBBR-iFAS  and may be combined with proprietary S&L process zones and equipment components, including:

Pre-treatment:

  • PISTA®Works™ (complete screening and grit removal packaged headworks)
  • OBEX™ Fine Screening
  • Dissolved Air Flotation

In-Tank Processes:

  • MBBR
  • iFAS
  • S&L AOAO and Bio-P Multi-Stage Biological Nutrient Removal (BNR) Zones
    • Nitrification / Denitrification
    • Phosphorous Removal
    • Various Aerobic, Anoxic and Anaerobic Zone combinations
  • Flow Equalization, Sludge Storage

Post-Treatment:

  • S&L Clarifiers (Hopper-style and stand-alone circular tankage / standard and flocculating)
  • Chemical Precipitation
  • DGF Tertiary Filtration (Integral or stand-alone tankage)
  • Disinfection (UV or Chlorination)
  • Dissolved Air Flotation

Benefits vs Conventional Biological Treatment Systems:

  • Reduced footprint
  • Enhanced process stability
  • Better handling of variations in flow, temperature, and other influent quality
  • Resistant to shock loads
  • Incremental capacity within the same basin by adding more media
