Artificial neural network modeling of wastewater treatment and desalination using membrane processes: A review
( Elsevier , 2021 , Article Review)The freshwater scarcity is causing a major challenge due to the growing global population. The brackish water and seawater are the biggest sources of water on the planet. Therefore, using desalination and water treatment ... -
Automated detection of anomalies in sewer closed circuit television videos using proportional data modeling
( International Society for Trenchless Technology , 2016 , Conference Paper)Sewer pipeline condition information is usually collected using closed circuit television (CCTV). Moreover, in order to evaluate the condition of pipeline, data should be processed by a certified operator, which is time ... -
Biocrude oil production from a self-settling marine cyanobacterium, Chroococcidiopsis sp., using a biorefinery approach
( Elsevier , 2023 , Article)Although the whole microalgal biomass is typically used as a feedstock for hydrothermal liquefaction (HTL), the conversion of a primary metabolite (i.e., carbohydrate) to biocrude is very low. In this study, a self-settling ... -
Combined influence of temperature and flow rate of feeds on the performance of forward osmosis
( Elsevier , 2016 , Article)The effect of the membrane orientation, feeds flow rate, feeds temperature, and combining effect of both temperature and flow rate on the membrane flux was investigated in order to enhance the performance of forward osmosis ... -
A comparison of bio-crude oil production from five marine microalgae – Using life cycle analysis
( Elsevier , 2022 , Article)Marine microalgae biomass could offer a viable feedstock for sustainably producing biofuel by hydrothermal liquefaction. In this study, five promising marine microalgae (i.e., Tetraselmis, Picochlorum, Synechococcus, ... -
Comparison of dual stage ultrafiltration and hybrid ultrafiltration-forward osmosis process for harvesting microalgae (Tetraselmis sp.) biomass
( Elsevier , 2020 , Article)In this study, a hybrid ultrafiltration-forward osmosis system was compared with a dual stage ultrafiltration process for the harvesting of marine microalgae. To the best of the author's knowledge none of the previous ... -
Comparison of nanofiltration with reverse osmosis in reclaiming tertiary treated municipal wastewater for irrigation purposes
