A hybrid nf-fo-ro process for the supply of irrigation water from treated wastewater: Simulation study
Hafiz, MhdAmmar; Alfahel, Radwan; Hawari, Alaa H.; Hassan, Mohammad K.; Altaee, Ali ( MDPI AG , 2021 , Article)Municipal treated wastewater could be considered as a water source for food crop irrigation purposes. Enhancing the quality of treated wastewater to meet irrigation standards has become a necessary practice. Nanofiltration ... -
Assessment of different pedestrian communication strategies for improving driver behavior at marked crosswalks on free channelized right turns
Abdulkarim, Almukdad; Muley, Deepti; Alfahel, Radwan; Alkadour, Firas; Ismail, Reem; Alhajyaseen, Wael K.M.... more authors ... less authors ( Elsevier , 2023 , Article)Introduction: Previous studies have indicated low driver yielding rates to pedestrians in various countries. This study analyzed four different strategies to improve driver yielding rates at marked crosswalks on channelized ... -
Comparison of nanofiltration with reverse osmosis in reclaiming tertiary treated municipal wastewater for irrigation purposes
Hafiz, MhdAmmar; Hawari, Alaa H.; Alfahel, Radwan; Hassan, Mohammad K.; Altaee, Ali ( MDPI AG , 2021 , Article)This study compares the performance of nanofiltration (NF) and reverse osmosis (RO) for the reclamation of ultrafiltered municipal wastewater for irrigation of food crops. RO and NF technologies were evaluated at different ... -
Developing sustainable draw solute for forward osmosis process using poly(amidoamine) dendrimer coated magnetic nanoparticles
Hassanein, Amani; Hafiz, Mhd Ammar; Hassan, Mohammad K.; Ba-Abbad, Muneer M.; AL-Ejji, Maryam; Alfahel, Radwan; Mahmoud, Khaled A.; Talhami, Mohammed; Hawari, Alaa H.... more authors ... less authors ( Elsevier B.V. , 2023 , Article)Forward osmosis is the least energy intensive water treatment membrane process, however, designing a sustainable draw solute is still a critical research necessity. In this work, we developed Poly(amidoamine) dendrimer ... -
Empirical evaluation of drivers’ start-up behavior at signalized intersection using driving simulator
Almallah, Mustafa; Alfahel, Radwan; Hussain, Qinaat; Alhajyaseen, Wael K.M.; Diasc, Charitha ( Elsevier , 2020 , Article)Start-up behavior at signalized intersection mainly depends on perception reaction time of drivers to the green phase. This study investigated the start-up behavior at signalized intersections by considering reaction time, ... -
Evaluation of ultrafiltration and multimedia filtration as pretreatmeprocess for forward osmosis
Hawari, Alaa H.; Hafiz, Mhdammar; Yasir, Ahmed T.; Alfahel, Radwan; Altaee, Ali ( 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 ... -
Impact of high turbidity on reverse osmosis: Evaluation of pretreatment processes
Hafiz, Mhd Ammar; Hawari, Alaa H.; Yasir, Ahmed T.; Alfahel, Radwan; Hassan, Mohammad K.; Altaee, Ali... more authors ... less authors ( Desalination Publications , 2020 , Article)This study evaluates the performance of sand filtration (SF) and ultra-filtration (UF) as pretreat-ment processes for reverse osmosis (RO) for seawater with turbidities of 4.8, 23.2, and 99.7 NTU. For seawater with a ... -

Techno-economic assessment of forward osmosis as a pretreatment process for mitigation of scaling in multi-stage flash seawater desalination process
Hafiz, MhdAmmar; Alfahel, Radwan; Altaee, Ali; Hawari, Alaa H. ( Elsevier , 2023 , Article)Thermal desalination processes suffer from the formation of scalants on the heat exchangers of the evaporator unit which negatively affect the process efficiency. This study evaluated the technical and economic feasibility ... -
Unlocking the application potential of electrocoagulation process through hybrid processes
Almukdad, Abdulkarim; Hafiz, MhdAmmar; Yasir, Ahmed T.; Alfahel, Radwan; Hawari, Alaa H. ( Elsevier , 2021 , Article Review)Electrocoagulation (EC) has attracted attention during the recent years due to its ease of use and high removal rate of organic and inorganic pollutants. It was found that using EC as a pretreatment process can decrease ...
