A fouling suppression system in submerged membrane bioreactors using dielectrophoretic forces
( Elsevier , 2015 , Article)A novel method was developed to suppress membrane fouling in submerged membrane bioreactors. The method is based on the dielectrophoretic (DEP) motion of particles in an inhomogeneous electrical field. Using a real sample ... -
A review of fouling mechanisms, control strategies and real-time fouling monitoring techniques in forward osmosis
( MDPI AG , 2019 , Article Review)Forward osmosis has gained tremendous attention in the field of desalination and wastewater treatment. However, membrane fouling is an inevitable issue. Membrane fouling leads to flux decline, can cause operational problems ... -
Ceramic membrane filtration of produced water: Impact of membrane module
( Elsevier B.V. , 2016 , Article)Produced water (PW) generated from oil exploration requires rigorous removal of suspended matter (free oil and particulate solids) as tertiary treatment (downstream of hydrocyclone and gas flotation) if it is to be re-injected ... -
Clogging vs. fouling in immersed membrane bioreactors
( Elsevier Ltd , 2018 , Article)Whilst the fouling of MBR membrane surfaces has been very extensively explored by the academic community, there is an increasingly widespread recognition by practitioners of the issue of clogging of membrane channels with ... -
Effect of membrane fouling on fertilizer-drawn forward osmosis desalination performance
( MDPI AG , 2020 , Article)Fertilizer-drawn forward osmosis (FDFO) has garnered immense attention for its application in the agricultural field and its potential to reuse wastewater sustainably. Membrane fouling, however, remains to be a challenge ... -
Fabrication of fouling resistant Ti3C2Tx (MXene)/cellulose acetate nanocomposite membrane for forward osmosis application
( Elsevier Ltd , 2020 , Article)In this study, Ti3C2Tx (MXene) was used to enhance the fouling resistance of FO flat-thin film membranes. Mixed-matrix Ti3C2Tx (MXene)/ cellulose acetate (CA) membranes with different (wt%) loading of MXene were fabricated ... -
Fouling mitigation strategies for different foulants in membrane distillation
( Elsevier , 2021 , Article)Providing clean water to a rapidly growing population is an issue that is currently getting lots of attention to offer a sustainable solution for water scarcity. Membrane distillation (MD) is one of the latest technologies ... -
Hybrid coagulation-NF membrane processes for brackish water treatment: Effect of pH and salt/calcium concentration
( Elsevier B.V. , 2016 , Article)In order to reduce membrane fouling propensity, membrane technologies in water treatment and desalination processes have been coupled with coagulation process. However, the fouling issues still persisted. It is believed ... -
Impact of aeration rate and dielectrophoretic force on fouling suppression in submerged membrane bioreactors
( 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 ... -
Impact of combined oil-in-water emulsions and particulate suspensions on ceramic membrane fouling and permeability recovery
( Elsevier B.V. , 2019 , Article)The application of crossflow ceramic microfiltration (CFCMF) to the removal of emulsified oil from a simple analogue of raw produced water (PW) arising from oil exploration has been studied. Outcomes relate to surfactant ... -
An investigation into fouling, wetting and their mitigation using commercial Antiscalant in membrane distillation desalination
(2017 , Master Thesis)An experimental investigation into membrane fouling and loss of hydrophobicity was carried out in direct contact membrane distillation (DCMD) desalination of high salinity seawater. The membrane used was a commercial ... -
Magnesium recovery from desalination reject brine as pretreatment for membraneless electrolysis
( Elsevier B.V. , 2022 , Article)Alkali-earth metals pose a significant challenge to water treatment technologies and electrochemical processes due to their propensity to precipitate as metal hydroxides, which can deposit on membranes and/or electrodes ... -
Novel and robust machine learning approach for estimating the fouling factor in heat exchangers
( Elsevier , 2022 , Article)The fouling factor (Rf) is an operating index for measuring an undesirable effect of solids’ deposition on the heat transfer ability of heat exchangers. Accurate prediction of the fouling factor helps appropriate scheduling ... -
Quantifying and reducing concentration polarization in reverse osmosis systems
( Elsevier , 2023 , Article Review)Reverse osmosis (RO) is an efficient water purification technique because of its high selectivity and permeability. During RO operation, rejection of solutes at the membrane surface leads to generation of a concentration ... -
Recent developments in ultrafiltration membrane technology for the removal of potentially toxic elements, and enhanced antifouling performance: A review
( Elsevier , 2023 , Article)The presence of high concentrations of heavy metals (potentially toxic elements) in water bodies generates serious environmental issues and health problems that led to a dramatic increase in wastewater treatment costs. ... -
Reducing flux decline and fouling of direct contact membrane distillation by utilizing thermal brine from MSF desalination plant
