Membrane Bioreactor (MBR) technology combines conventional activated sludge (CAS) treatment with a membrane liquid-solid separation process.
Membrane Biological Reactor (MBR) vs. Conventional Activated Sludge (CAS)
FII MicroClear™ MBRs
Filter Innovations offers FII MicroClear™ MBR systems for treating both municipal and industrial wastewater. These innovative systems are the result of a successful collaboration between Filter Innovations and Weise Water System GmbH (Germany) - the leading European supplier of membrane technology.
FII MicroClear™ MBRs are robust enough to withstand variations in operation conditions due to fluctuating sludge concentration, sludge age and organic load. As a result, these systems are particularly well-suited to wastewater treatment plants with significant seasonal or daily variations in wastewater loading, including work camps, tourist areas, or remote, decentralized districts.
The core of the FII MicroClear™ MBR - the membrane filter - is submerged directly into the untreated water. The filtrate is drawn through and out of the filter by a slightly negative pressure. The MicroClear™ filter (pore size = 0.05 micron) is an effective barrier against solids, organic pollutants and microorganisms. Its robust plastic construction and environmentally friendly self-cleaning capabilities make the MBR system an unrivalled product.
MicroClear™ Membrane Filtration Principle Out-In
Advantages of the FII MicroClear™ MBR
| Small footprint |
MBR footprint is 75% smaller than that of a conventional activated sludge (CAS) system |
| Small sludge yield |
MBR sludge yield is 60-80% less than that of a CAS treatment plant |
| Improved biodegradation process |
MBR membrane can retain soluble material with high molecular weight, improving its biodegradation in the bioreactor;
Longer retention of nitrifying bacteria, resulting in greater nitrification |
| Many great design features |
• Modular expandability
• Ideal for upgrading existing systems
• Well-suited to on-site wastewater treatment and decentralized approaches to wastewater management
• Simple, sophisticated remote monitoring |
Exceptional effluent quality
|
• BOD < 5 mg/L
• Turbidity < 1 NTU
• Filters bacteria (1-2 µm) and parasites
(5-50 µm) passing through the membrane
• Virus removal - 99.999%
• Effective barrier against chlorine-resistant pathogenic microorganisms (e.g., Crystosporidium, Giardia Lamblia) |
