imemflo Membrane Bioreactor -MBR

Membrane Bioreactor (MBR) is an efficient and most advanced technology for municipal and industrial wastewater. treatment process which combines high-efficiency membrane separation technology with conventional activated sludge process (CAS).

MBR combines the advantages of membrane filtration and biological treatment technology. It uses a membrane module instead of a secondary sedimentation tank in conventional activated sludge process. The filtration membrane greatly improves the solid-liquid separation ability of the system, producing higher permeate water quality and volume.

imemflo has two different variants
1. imemflo – Flat sheet MBR
2. imemflo – Hollow fiber
  a. Hollow Fiber MBR (H-MBR)
  b. PVDF Hollow Fiber (HP- MBR)

Based on a proprietary high-strength PVDF (Polyvinylidene fluoride) material, imemflo’s membranes have permanent hydrophilic properties. The hydrophilic properties will not be lost regardless of light exposure, drying, weather variations. PVDF exhibits superior physical strength and enhanced chemical stability.

imemflo MBR Advantages

  • Higher permeate quality for discharge or reuse
  • No impact from feed water’s fluctuation
  • Longer sludge retention time (SRT): Less sludge
  • Reduced footprint - ½ to ¼ of a CAS plant.
  • High MLSS sludge concentrations (4 to 12 g/l)
  • Biological removal of ammonia by nitrification process
  • No clarifiers (no bulking and sludge rising problems)

imemflo Features

Permanent hydrophilic properties

Dry storage, engineering installation and maintenance do not require hydrophilization pretreatment. Reduce the cost of transportation, operation & maintenance.


High flux & effluent quality (SDI < 2)

Uniform pore size ensures consistently high permeability with minimal clogging. Strong anti-fouling ability, and long service life.


Unique membrane structure

Numerous small-diameter pores are distributed throughout the membrane surface with a narrow diameter distribution. With this unique asymmetric structure ensures higher treated water quality and minimizes fouling and clogging for consistently high water permeability.

Treatment Process

Traditional Wastewater plant

The Imemflo is a fully self-contained MBR wastewater treatment system incorporating the following process stages:
1. Inlet screening
2. Primary / Anoxic tank – DE nitrification
3. Aeration / Membrane Bioreactor tank -Nitrification
4. submerged membrane filtration modules
5. Permeate receiving and disinfection
6. RAS and sludge removal.


imemflo Membrane Bio Reactor (MBR)can best be described as one part of a biological process where small microbes degrade pollutants before being filtered by a collection of submerged membranes. Membranes are housed in modules that are, in turn, assembled into cassettes and installed in a tank (called an MBR). Air introduced through integral diffusers scours membrane surfaces during filtration, mixes the tank and provides oxygen to the biological process.
A growing body of research suggests that properly designed and operated MBR systems offer several advantages over conventional technologies in terms of protecting public health and improving sustainability including but not limited to:
• Use as pre-treatment for reverse osmosis (RO) systems
• Improved removal of micro pollutants (micro constituents)
• Reduced disinfection requirements
