Recycled reverse osmosis membranes for forward osmosis technology
Desalination, 2021 An alternative use of end-of-life reverse osmosis (RO) membranes is proposed for forward osmosis (FO) application as recycled FO (RFO) membranes and transformed recycled FO (TRFO) membranes. Different passive cleaning protocols in pilot plant and laboratory scale were followed using sodium hypochlorite (NaClO) at different concentrations and exposure ...

Eco-friendly forward osmosis membrane manufacturing using dihydrolevoglucosenone
Results in Engineering, 2022 Semipermeable membranes are generally synthesized using solvents which harm the environment and human health. Common organic solvents like n-methyl-2-pyrrolidone (NMP), dimethylformamide (DMF), dimethylacetamide (DMA), and dimethyl sulfoxide (DMSO) have ...

On the potential of forward osmosis to energetically outperform reverse osmosis desalination [PDF]
, 2014 We provide a comparison of the theoretical and actual energy requirements of forward osmosis and reverse osmosis seawater desalination. We argue that reverse osmosis is significantly more energy efficient and that forward osmosis research efforts would ...

Exploring the differences between forward osmosis and reverse osmosis fouling [PDF]
, 2018 A comparison of alginate fouling in forward osmosis (FO) with that in reverse osmosis (RO) was made. A key experimental finding, corroborated by membrane autopsies, was that FO is essentially more prone to fouling than RO, which is opposite to a common ...

Forward Osmosis: A Critical Review [PDF]
Processes, 2020 The use of forward osmosis (FO) for water purification purposes has gained extensive attention in recent years. In this review, we first discuss the advantages, challenges and various applications of FO, as well as the challenges in selecting the proper draw solution for FO, after which we focus on transport limitations in FO processes.
