Industrial Membrane Bioreactors
By combining over thirty years experience in applying membrane filtration and biological treatment, Dynatec's Hi-Rate MBR is perfect for industrial applications.
Dynatec's Hi-Rate MBR System
Dynatec Systems’ Hi-Rate MBR uses external crossflow type UF membranes that have over three times the flux as the hollow fiber alternatives (60- 90 GFD vs. 20-25 GFD for hollow fibers).
Higher flux means less membrane surface area, ultimately saving capital cost on your project. Bio-reactor aeration alternatives include coarse bubble aeration for commercial systems or, for higher strength industrial waste, the use of more efficient jet aeration for power savings in deep tanks.
Dynatec's High Rate MBR uses true UF Filtration, with 0.03 micron cross flow tubular membranes. Others use microfiltration (MF) with pore sizes 0.1- 0.4 micron, allowing more contaminants to make their way across the membrane surface. Dynatec Systems has installed over 500 membrane systems in over 30 years of providing wastewater solutions. Combining sound engineering and process design with state of the art materials of construction has produced the High-Rate MBR.
Hi-Rate Membrane Bioreactor Benefits
- 3-4 times the flux of other systems in a smaller footprint
- Lower Capital Costs
- Tubular non-clog design deduces cleaning requirements
- Automatic Operation
- No Clarifier upsets
- Much higher performance than conventional systems
Applying MBR to Industrial Wastewater
The membrane biological reactor (MBR) configuration has proven to be optimal for treatment of many industrial wastewaters when treatment efficiency is an important consideration.
The MBR is the ideal bioreactor configuration for treatment of organic or inorganic contaminants present in industrial wastewaters. MBR’s operate at a higher efficiency while achieving consistent design performance objectives. This makes MBR a more cost effective method of treatment when performance and tank requirements are considered.
Bioreactor systems such as the conventional activated sludge system, sequencing batch reactor system and trickling filters are typically designed for operation at a lower volumetric removal rate, requiring larger tanks and more space. These conventional systems often experience upsets that inhibit settling and therefore require much more operator attention than a membrane bioreactor.
The membrane biological reactor has proven to be optimal for treatment of many industrial wastewaters because it is less susceptible to upsets. The MBR’s performance is not affected by changes in sludge settleability like the conventional systems, making MBR a wise choice for industrial systems that have more difficult to treat waste streams. Dynatec has over 30 years experience in dealing with difficult to treat industrial wastewaters using membrane filtration.
