Alfa Laval membrane bioreactor system

The Alfa Laval Membrane Bioreactor (MBR) system enables breweries to treat wastewater on-site using membrane filtration technology. The system enables breweries to save on discharge fees to the local wastewater treatment plant or to safely and cheaply discharge brewery wastewater directly into a lake, watercourse or the sea.

The system significantly reduces the COD/BOD from wastewater. It combines secondary and tertiary wastewater treatment, providing effective filtration down to 0.01 µm and delivering effluent quality that is suitable for re-use.

Options for re-use include: technical/process water for non-sanitary uses such as cleaning water, toilets, irrigation, cooling towers; potable-quality water for use in sanitary-standard processes that include sanitary cleaning and bottle washing (if a polishing step such as reverse osmosis is added).

The system is compact, easy to install and operate, requires minimal manpower and maintenance, and has low operating costs.
