The need to recycle wastewater and stricter environmental regulations make an MBR system a viable solution for current and future wastewater treatment.  Siemens makes biological reactors for large municipal wastewater applications that can be fit into concrete tanks, package plants for smaller flows, new developments and and hotels as well well as a system developed for the petroleum industry to meet most refinery standards.

 

Xpress™ Membrane Bioreactor Package Plants
Designed for applications from 25,000 gpd to 100,000 gpd,  plants utilize the immersed membrane biological reactor  process, a unique wastewater treatment process designed for municipal and industrial applications, and land developers.

Retrofit your treatment plant with an Integrated Membrane Bioreactor Process Upgrade Solution
Existing wastewater installations can benefit from Siemens' MBR experience.  For example, a Membrane Bioreactor, paired with an Envirex Orbal® or vertical loop reactor (VLR®) oxidation system and aerated anoxic process, is designed for operators seeking activated sludge, advanced secondary sludge treatment, simultaneous nitrification-denitrification, biological phosphorus removal or stormwater treatment and reduced energy consumption.  Reengineering biological processes with a membrane  bioreactor system unit can reduce footprint requirements and meet strict effluent regulations.  Plants dealing with biosolids disposal issues will be interested in the Cannibal solids reduction process paired with a SmartMBR control package.
