MBR Solutions for Wastewater Treatment

MBR is ideal for the treatment of medium strength industrial wastewater, being the most efficient for removing the organic pollutants and nutrient loads. The UF membranes retain the biomass (MLSS) within the bioreactor, thus producing a superior and consistent quality effluent, free of solids, turbidity and pathogens.

Years of Experiences

Minimize short and long-term environmental impact

In an effort to minimize the short and long-term environmental impact, industries across the globe are facing increasing challenges and costs related to wastewater management. As a result, most of the industrial facilities have built their own treatment plants, thus achieving regulatory compliance, avoiding the fees for sewer discharge, and reducing their water footprint by means of water reuse.

The MBR is essentially a high-efficient evolution of the conventional activated sludge process, where the clarifiers are replaced by the tubular UF modules. In this way, significant improvements are achieved: superior effluent quality, higher biodegradation rates, smaller footprint, less sludge production and reuse possibilities. All these features are essential for coping with the stringent discharge quality requirements and the economic benefits of water reuse faced by almost all the industrial sectors.

MBRs remove up to 99% of COD, compared to 90-95% in conventional activated sludge processes. The operation with higher MLSS concentration – even up to 30 g/L – results in minimum footprint requirements and decreased production of excess sludge. The filtrate produced by the membranes is free of solids (TSS < 1 mg/L) and turbidity (< 1 NTU), and presents SDI values lower than 3, optimum for further RO treatment if required.

External Crossflow Filtration Technology​

Berghof Membranes specializes in external MBRs that are positioned outside the bioreactor and utilize crossflow velocity to keep the membranes working at optimal conditions. Your benefits:

Less membrane fouling

Long membrane lifespan

Ease of maintenance

Flexible and adaptable

Stable long-term performance

Reliable performance with complex wastewater

Compactness and modularity

Closed system. No odor, VOCs

External crossflow filtration vs. Submerged membrane filtration

Unlike the outside-in submerged membranes, our inside-out external tubular modules provide higher fluxes with less frequent cleanings and reduced maintenance operations. The cross-flow operation allows operating with higher MLSS and dealing with complex wastewaters, containing FOG, hardness or high levels of recalcitrant matter. The external filtration systems are quickly assembled and do not require complex civil works. The modules are easily accessible for inspection and maintenance, reducing system downtimes to a minimum. Finally, the enclosed filtration system is clean and operator-friendly, with neither odor nor exposure to the wastewater.

inside-out vs. out-side in filtration

Upgrading of existing wastewater treatment facilities

Many industrial facilities are facing the need for upgrading their existing treatment plants. There are a number of reasons  pushing the conversion:

 

Under any of these circumstances, the conversion of the existing CASP or SBR processes into  MBRs turns out as the most favourable solution, providing significant benefits at both technical and economical sides. By coupling the external tubular UF system to the existing biological reactor the wastewater treatment plant will provide a much better quality treated water, and the capacity of the plant shall be increased up to three times if required. The external MBR system has undoubted advantages for retrofit and conversion:

Plug & Play

The conversion is fast and simple and requires minimal civil work.
The conversion is fast and simple: The external UF skids are plug&play systems that require minimum civil works. As soon as the skids are connected hydraulically to the existing bioreactor, the system is commissioned and full-running in just a few days.

CAPEX

There is not a need for an additional tank, as is the case with the submerged membranes.
There is not a need for an additional tank, as is the case with the submerged membranes. UF skids are modular and their location and distribution can be adapted to the available space. The reduced height allows installing the UF system inside a conventional room.

Savings on footprint

Decommissioning of the existing clarifiers and DAF pretreatment saves space.
Despite the fact that the plant is upgraded, space savings can be achieved: the decommissioning of the existing clarifiers or the DAF pretreatment provides more than the space required for the membrane filtration system.

Existing biological reactor

When upgrading is required existing biological reactor can be used.
When upgrading is required for dealing with increased wastewater flow and/or organic load, the membranes allow increasing the MLSS from the standard 3-4 g/L up to 12-15 g/L. The only change to be made is the upgrading of the aeration system.
