A hybrid forward osmosis/reverse osmosis process for the supply of fertilizing solution from treated wastewater
Hafiz M.A.; Hawari A.H.; Altaee A. ( Elsevier Ltd , 2019 , Article)This work investigates the application of a hybrid system that combines forward osmosis (FO) and reverse osmosis (RO) processes for the supply of a fertilizing solution that could be used directly for irrigation purposes. ... -
Dilution of seawater using dewatered construction water in a hybrid forward osmosis system
Hawari A.H.; Al-Qahoumi A.; Ltaief A.; Zaidi S.; Altaee A. ( Elsevier Ltd , 2018 , Article)In this study, dewatered construction water was used for the first time as the feed solution in a combined pretreatment-forward osmosis process to dilute seawater (i.e. draw solution) for further desalination. It was found ... -
Forward osmosis feasibility and potential future application for desalination
Altaee A.; Alanezi A.A.; Hawari A.H. ( Elsevier , 2018 , Book chapter)Forward Osmosis has been intensively investigated for seawater desalination in the past decade. However, the application of technology is still limited apart from a number of pilot and small commercial plants. Initially, ... -
Fouling suppression in submerged membrane bioreactors by obstacle dielectrophoresis
Du F.; Hawari A.H.; Larbi B.; Ltaief A.; Pesch G.R.; Baune M.; Th?ming J.... more authors ... less authors ( Elsevier B.V. , 2018 , Article)Submerged membrane bioreactor (MBR) is currently believed to be an efficient biological treatment for reusing and recovering wastewater to extenuate the ever increasing water scarcity crisis. To mitigate the main problem, ... -
Impact of aeration rate and dielectrophoretic force on fouling suppression in submerged membrane bioreactors
Hawari A.H.; Larbi B.; Alkhatib A.; Yasir A.T.; Du F.; Baune M.; Thöming J.... more authors ... less authors ( Elsevier B.V. , 2019 , Article)Membrane bioreactors (MBRs) present a unique opportunity in waste water treatment by combining the activated sludge process with membrane filtration. Although MBRs require less area, produce less volume of sludge and have ... -
