Automotive Industry | MBR Wastewater Treatment

With 50 years of experience in tubular PVDF membrane technology and industrial effluent treatment, Berghof Membranes has developed a compact external MBR treatment technology, called B-SMART^TM, that adapts to the varying volume ofwastewater in the tractor factory. The two initial wastewater streams are pretreated separately:

• The industrial stream is pretreated with a complete physical chemical treatment to remove oils and heavy metals.
• The sewage stream first passes through a strainer to remove large coarse solids, then through a filter to separate fibers and smaller particles, and then the final stage to remove oils and grease.

The two streams are then mixed and sent to the membrane bioreactor (MBR) in order to reduce the organic load of the wastewater. A portion of the permeate is re-used for the internal facilities of the factory, and the rest is discharged directly to the municipality.

The B-SMART^TM external MBR achieves a complete retention of the biomass in the aerobic reactor and delivers significant improvement of the digestion process. This advanced technology features an intelligent combination of variable crossflow velocity, backwashing, chemicalenhanced backwash and cleaning-in-place (CIP).

The software analyzes the system in real-time and automatically adjusts the parameters based on the conditions of the feed stream, ensuring smooth and continuous operation.
