High quality discharge and reuse from MBR – Cereal Plant

Since the plant produces a food product, ultimate water quality was vital. The two-stage membrane system (MBR + RO) and final sterilization with ultraviolet (UV) treatment provided the quality assurance that plant management required. In addition, the membranes used in the MBR system are external to the aeration basin and are tubular. This type of membrane is much less susceptible to failure than the immersed type.

This process combines aerated biological treatment with an out-of-basin ultrafiltration (UF) system. In combination with reverse osmosis treatment, Dynatec was able to provide the client with the necessary assurances that the water quality would not be compromised, and that the water would be suitable for process purposes, such as boiler feed water.

The 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 wastewater treatment systems. MBRs operate at a higher efficiency while achieving consistent design performance objectives. This makes MBR a more cost effective method of industrial wastewater 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 wastewater treatment systems 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 Systems has over 42 years experience in dealing with difficult to treat industrial wastewaters using membrane filtration.
