... production. Membrane contactors with non-porous polymeric membranes were selected to be suitable since they do not only absorb the by-product carbon dioxide effectively but they also supply sterile conditions, they withstand high feed pressures and they prevent a contamination of the gas... of this technology in biohydrogen production processes has been proven.

... and obtaining methane (biogas); the resulting CO2 after CH4 separation can be fed back into the photobioreactor as an additional source of carbon for the whole system. However, after UF separation, the resulting biomass can be used as fertilizer. The anaerobic photobioreactor can be used... in the form of combustive gases (CH4 and H2) with a net CO2 consumption. Keywords: Membrane contactors; Gas separation; Bioreactor; Carbon dioxide removal 1. Introduction The development of new, low energy consuming and clean technologies has to include the *Corresponding author. utilizatio ...
