Removal of trace organic contaminants by melamine-tuned highly cross-linked polyamide TFC membranes

Reduction of the Structure Parameter of Forward Osmosis Membranes by Using Sodium Bicarbonate as Pore-Forming Agent

“…9 In this process, solvent molecules spontaneously diffuse through a semipermeable asymmetric FO membrane from the feed solution (with high solvent chemical potential) to the draw solution (with low solvent chemical potential) while impeding the exchange of solute. 10 FO has prominent features in contrast to all of the pressure-driven separation processes, including alleviated membrane fouling tendency, low operating cost, low energy consumption, and higher water recovery rate. 11,12 The conventional RO membranes are insufficient for the FO system due to the significantly different desalination mechanisms in the FO and RO processes.…”

“…The forward osmosis (FO) process, as a promising membrane purification method for desalination and wastewater treatment, has attracted more attention in recent years . In this process, solvent molecules spontaneously diffuse through a semipermeable asymmetric FO membrane from the feed solution (with high solvent chemical potential) to the draw solution (with low solvent chemical potential) while impeding the exchange of solute . FO has prominent features in contrast to all of the pressure-driven separation processes, including alleviated membrane fouling tendency, low operating cost, low energy consumption, and higher water recovery rate. , …”

Water Purification of Classical and Emerging Organic Pollutants: An Extensive Review

“…In this way, they achieved an almost complete rejection of the endocrine disrupter by using polyamide-based RO membranes (BW30, XLE BWRO and AD SWRO). Rastgar et al [120] selected forward osmosis thin film composite (FOTFC) membranes to eliminate 97.3% of atrazine present in aqueous solution at 50 mg/L.…”

Aerogels in passive solar thermal desalination: a review

“…In this context, developing robust and effective desalination techniques with minimal energy input and environmental footprint for pure water production from abundant seawater has always been the subject of intense research. [6][7][8][9] Luckily, water stress countries benet from ample solar energy; thereby, applying thermal desalination powered by sunlight seems a rational solution. 10 The poor solar absorption and huge heat loss cause a dramatic reduction in the rate of solar vapor generation in traditional systems.…”
