Modeling and sensitivity analysis of the forward osmosis process to predict membrane flux using a novel combination of neural network and response surface methodology techniques
( MDPI AG , 2021 , Article)The forward osmosis (FO) process is an emerging technology that has been considered as an alternative to desalination due to its low energy consumption and less severe reversible fouling. Artificial neural networks (ANNs) ... -
Integrated sensing technologies for detection and location of leaks in water distribution networks
( IWA Publishing , 2017 , Article)Water distribution networks (WDNs) are infrastructure systems that have high socioeconomic values, for which efficient operation and management are required to ensure minimal amounts of waste which can be represented in ... -
Evaluation of ultrafiltration and multimedia filtration as pretreatmeprocess for forward osmosis
( Desalination Publications , 2020 , Article)In order to reduce scaling in a multistage flash (MSF) desalination plant, the brine reject can be diluted using forward osmosis (FO) before recycling. In this FO process, the brine is used as the draw solution (DS) and ... -
Steel slag promoted electrocoagulation process for the treatment of produced water
( Desalination Publications , 2020 , Article)Produced water is a by-product produced from the oil and gas industry. It poses a significant threat to the environment due to its high salinity and high pollutant concentration. In this paper, steel slag was used to enhance ... -
Defect based deterioration model for sewer pipelines using bayesian belief networks
( Canadian Science Publishing , 2017 , Article)A defect based deterioration model to determine the condition ratings in a probabilistic manner for sewer pipelines is presented in this paper. Bayesian belief network (BBN) is used to develop a static model using probabilities ... -
The influence of aeration scheme and aeration rate on the permeate flux for wastewater treatment using membrane bioreactors: Experimental and artificial neural network modeling
( Desalination Publications , 2021 , Article)In this paper, the effect of time, aeration scheme, aeration rate, and mixed liquor suspended solid (MLSS) concentration on the permeate flux in membrane bioreactors have been studied. Aeration rates of 0.5, 1.0, and 1.5 ... -
An analytic network process condition assessment model for sewer pipelines
( Civil-Comp Press , 2015 , Conference)As sewer pipelines age, the need for their upgrading, maintaining, and repairing arises. Simultaneously, inadequate sewer pipelines might lead to catastrophic failures. Thus, decision makers must have a detailed knowledge ... -
Examining engineering students' perceptions of learner agency enactment in problem- and project-based learning using Q methodology
( John Wiley and Sons Inc , 2022 , Article)Background: Few studies have reported how students enact learner agency in a team setting or examined what elements of team settings students perceive as more supportive of their learning in problem- and project-based ... -
A novel electrocoagulation electrode configuration for the removal of total organic carbon from primary treated municipal wastewater
( Springer , 2020 , Article)In this paper, the removal of total organic carbon (TOC) from a primary treated municipal wastewater using a new electrode configuration in electrocoagulation was evaluated. The used electrode configuration induces a ... -
Efficient extraction of lipids from microalgal biomass for the production of biofuels using low-cost protic ionic solvents
( Elsevier , 2023 , Article)The valorization of lipids available in microalgal biomass supports the indispensable transition from fossil fuels to renewable energy systems such as biofuels. Ionic liquids have been long investigated for the effective ... -
Comparison of dual stage ultrafiltration and hybrid ultrafiltration-forward osmosis process for harvesting microalgae (Tetraselmis sp.) biomass
