Flexographic ink wash wastewater treatment, due to the presence of heavy metals, such as zinc, lead, copper and chrome make discharge to most sewer plants, a problem. In some cases, color alone can be a reason for municipal waste treatment authorities to refuse this material.

Discharges may also be limited by high Total Suspended Solids (TSS) and high Biochemical Oxygen Demand (BOD).

The MBR is the ideal bioreactor configuration for treatment of organic or inorganic contaminants present in industrial wastewaters. MBRs 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 MBR 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 42 years experience in dealing with difficult to treat industrial wastewaters using membrane filtration.
