In forward osmosis (FO), an osmotic pressure gradient generated across a semi-permeable membrane is used to generate water transport from a dilute feed solution into a concentrated draw solution. This principle has shown great promise in the areas of

Optimum pH for methanogenesis in an anaerobic digester is well known, however, the effect of pH and its control strategy for the ex-situ biomethanation is understudied. In this study, two pH control strategies, namely the addition of buffer media and

Ex-situ biomethanation in a biotrickling filter is being developed as a robust technology for the conversion of CO2 to CH4 using H2 generated from renewable power. The technology uses hydrogenotrophic methanogens in a biofilm as the catalyst and the

Hydrogenotrophic biomethanation in a biotrickling filter has been reported to be a proven technology for biological biogas upgrading in recent studies. However, the preparation of enriched hydrogenotrophic methanogens in a separate reactor prior to b

Hydrogenotrophic methanogenesis is a power-to-gas method, biologically converting CO 2 to CH 4 using H 2 generated from electrical power. However, the low rate of gas-liquid mass transfer of H 2 limits the hydrogenotrophic methanogens biocatalyst. We

Secondary settling tanks (SSTs) are the most hydraulically sensitive unit operations in biological wastewater treatment plants. The maximum permissible inflow to the plant depends on the efficiency of SSTs in separating and thickening the activated s
