Food & Beverage: AnMBR WASTEWATER TREATMENT

Key Message

AnMBR technology is known to be one of the best available technologies for treating the high-strength food and beverage wastewater. With a positive net energy balance and a superior effluent quality that avoids complex post-treatment, this technology is highly competitive in terms of CAPEX and OPEX.

Benefits of AnMBR Treatment with tubular UF

AnMBR technology allows recovering energy from the food and beverage waste streams. For the high-strength F&B wastewaters (COD > 10 – 15 g/L) the anaerobic MBR is often the best choice. The Berghof tubular UF is coupled to a simple CSTR digester, allowing the operation with high OLRs (10 kg COD/m3·day) while producing a high-quality effluent. The Berghof membranes ensure the complete retention of the biomass within the anaerobic digester and bring a significant improvement in the digestion process, making it more robust, reducing the footprint, and increasing biogas production. In the F&B industry, Berghof AnMBR offers major advantages over other anaerobic technologies based on granular sludge, such as UASB and EGSB.

Biogas production

Increased biogas production due to the higher COD removal when compared with conventional anaerobic technologies. Energy recovery is maximized (average 3.7 kWh/kg CODremoved).

Ability to cope with FOG

Ability to operate with the high TSS and FOG concentrations found in some F&B waste streams, in contrast with the granular anaerobic systems which are known to suffer degranulation under these conditions.

Effluent Quality​​

Better effluent quality: COD removals up to 98 – 99% and complete retention of solids, allowing the direct discharge after the AnMBR or the post-treatment with RO if required so.

Food and beverage AnMBR wastewater treatment - the process

The high-strength waste streams generated in food and beverage production are sent to the equalization tank. Here, chemicals are often required for neutralization, since the use of acid and alkaline products for cleaning and sanitizing results in a highly variable pH. 

The tubular anaerobic MBR removes the organic pollutants in a single treatment step, producing renewable energy in form of biogas and a high-quality treated water. This effluent can be disposed into the sewer, although in some cases it even fulfills the requirements for water body discharge. Reuse is also possible after a reverse osmosis step.
