1. MBR Applications

MBR are generally a preferred option when,

1.1 There's limited space

1.2 End user requires high quality treated water (e.g. for water reuse)

Increasingly tighter environmental regulations together with a decreasing MBR CAPEX and OPEX has led to an boost in installations and in size all over the world. MBR have now been implemented in more than 200 countries worldwide with a number of plants over 4,200 m3/d in capacity and their growth rates of up to 15% are regularly reported in various market analyses.

Usually MBR technology is applied to those wastewater with a readily biodegradable organic carbon content. The latter is especially true when it comes to the food and beverage sector which has made an extensive use of MBR technologies.

Wastewater markets which are containing sparingly biodegradable content (e.g. landfill leachate and pharmaceutical effluents) have also seen a grow of MBRs due to the long solid retention times (SRT) that allow for an improved Biological Treatment over the one from the conventional biological processes.

Waters that contain suspended oil (vegetable or mineral) require pretreatment (e.g. plate separation, dissolved air flotation or both) in order to protect the membrane.

Although the MBR global market is mainly dominated by a few major companies, the number of technology suppliers continues to grow, with over 70 Mbr Membrane module products available on the market today.

2. In general MBR have been applied to treat effluent in a number of industrial sectors, like:

2.1 food and beverage − high in organic loading

2.2 petroleum industry − exploration, refining and petrochemical sectors

2.3 pharmaceutical industry – have active pharmaceutical ingredients (APIs)

2.4 pulp and paper industry − high levels of suspended solids, COD and BOD

2.5 textile industry effluent − re-biodegradability, toxicity, FOG content and color

2.6 landfill leachate−wide variety of dissolved and suspended organic and inorganic compounds

2.7 ship effluents − legislative requirements and space restrictions.

2.8 Industrial versus municipal treatment

3. What are the advantages of MBR?

It's generally acknowledged that Membrane Bioreactors have a number of advantages over other wastewater technologies,

3.1 Independent control of HRT and SRT

3.2 High quality effluent

3.3 Small footprint

3.4 Improved bio-treatment.
