SEPURAN Green - Efficient biogas upgrading

Biogas is an eco-friendly energy source that is becoming increasingly important in today‘s energy supply. It can be used to generate power or heat or as a fuel, and provides a high energy yield per square meter of land. But an extensive upgrading and purification process is required before biogas is fed into the natural gas grid. New and highly selective polymer membranes from Evonik convert raw biogas simply and efficiently into highly pure biomethane. This increases yield and conserves valuable resources.

MBRs Don’t Have to Break the Bank

Membrane Bioreactors (MBRs) may have a reputation for being costly, but they don’t have to be. A survey of 137 MBRs on the US mainland shows that an MBR using flat plate technology is typically half to three-quarters the capital expenditure (CAPEX) of hollow fiber systems. There is some data that suggests MBR Systems are competitive with several other technologies, including oxidation ditches, SBRs, MBBRs, and BNR plants. There is insufficient data to say definitively that a flat plate system costs less, but the data suggests that it can be cost effective versus conventional systems treating to the same quality effluent.
