Membrane Bioreactor Technology (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).
Membrane Bioreactor 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 is one of the leading Membrane Bioreactor, MBR Manufacturer & Supplier
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.
Dry storage, engineering installation and maintenance do not require hydrophilization pretreatment. Reduce the cost of transportation, operation & maintenance.
Uniform pore size ensures consistently high permeability with minimal clogging. Strong anti-fouling ability, and long service life.
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.
Traditional Wastewater plant
The imemflo is a fully self-contained Membrane Bioreactor 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 bioreactor (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 Membrane bioreactor (MBR) systems offer several advantages over conventional technologies in terms of protecting public health and improving sustainability including but not limited to:
Waste water
All Commercial Establishments such as
Note:For different water quality, there will be a different water flow rate. So the user should fully test the membrane module. This parameter is tested at 25℃,-10KPa suction vacuum conditions based on municipal wastewater.
