Feasibility study of polyetherimide membrane for enrichment of carbon dioxide from synthetic biohydrogen mixture and subsequent utilization scenario using microalgae
Bakonyi, Péter; Peter, Jakub; Nemestóthy, Nándor; Malý, David; Kumar, Gopalakrishnan; Koter, Stanislaw; Kim, Sang-Hyoun; Kujawski, Wojciech; Bélafi-Bakó, Katalin; Pientka, Zbynek (Peer reviewed; Journal article, 2020)In this work, the potential of utilizing a polyetherimide (PEI) hollow-fiber membrane to separate synthetic biohydrogen mixture (H2/CO2) was studied. From the gas separation experiments, where the effects of feed to permeate ... -
A review on energy and cost effective phase separated pretreatment of biosolids
Rajesh Banu, Banu; Poornima Devi, T.; Yukesh Kannah, Kannah; Kavitha, S.; Kim, Sang-Hyoun; Muñoz, Raul; Kumar, Gopalakrishnan (Peer reviewed; Journal article, 2021-06)Extracellular Polymeric Substances (EPS) existent in anaerobic sludge proves to be a barrier for sludge liquefaction and biomass lysis efficiency. Hence EPS deaggregation heightens the surface area for the subsequent ...
