MBR WASTEWATER TREATMENT

Key Message

Refineries and petrochemical facilities are known for demanding robust, reliable and well-proven technology. The complexity of the wastewater generated and the increasing interest in water reuse makes Berghof Membranes the best partner for implementing tubular MBR technology: a guarantee of effluent quality and smooth operation, even under the most challenging operational conditions.

Benefits of MBR Treatment with tubular UF in the oil and gas industry

The external MBR with Berghof tubular membranes is known to be one of the best available technologies for dealing with refinery wastewater, especially when reuse practices are implemented.

Conventional biological treatments can be challenged by varying influent characteristics, refractory components, toxicity or inhibiting compounds. As a result, nitrogen removal and the high and consistent effluent quality cannot be always guaranteed. The MBR overcomes these constraints with the higher SRT and the more specialized biomass, achieving COD removals higher than 95% and complete nitrification. The most common configuration is based on an initial DAF process for removing the bulk oil, followed by the MBR. Berghof tubular membranes are able to cope with the emulsified hydrocarbons that could eventually leak from the DAF. This is a guarantee of stable and trouble-free operation even with the most complex refinery effluents.

The application in the petrochemical industry in based on the same approach, the main difference being that the range of complex hydrocarbons can be higher, although the variability in the composition is typically narrower and the oil concentration is lower.

Oil and gas MBR wastewater treatment - the process

The treatment of refinery wastewater is focused on the removal of organic matter with biological processes. After equalization and neutralization (if required), a flotation process is conventionally applied for removing the free and dispersed mineral oils. The clarified stream from the DAF subsequently enters the tubular MBR, where the dissolved hydrocarbons are removed. The ultrafiltration modules, coupled to the biological reactor, produce high-quality treated water that fulfills the most stringent standards for discharge in water bodies. Alternatively, the water footprint can be reduced by reusing this effluent, either directly or after reverse osmosis for uses where desalted water is required.
