“…16,17 Among them, polyelectrolyte solution can provide high osmotic pressure similar to salt solution and could be recovered by various means. The FO performance of many polyelectrolyte solutions has been explored in detail, including poly(sodium acrylate) (PAA-Na), 12 polyacrylamide (PAM), 18 poly(sodium 4-styrenesulfonate) (PSS), 19 poly N-isopropyl poly(aspartic acid sodium salt) (PAspNa), 20 poly(ethylene glycol) (PEG), 21 poly-(ethylenimine) (PEI), and so on. 22,23 Among these studies, polyelectrolytes with different molecular weights and func-tional groups endowed them with varied water flux of 1.0 to 12 LMH, when using DI water as feed and testing with the CTA FO membrane.…”

The physicochemical property of polyelectrolyte solutions has a great effect on their FO water flux; thus, it is of theoretical and practical importance to explore their relationship for the selection of efficient polyelectrolyte draw solutions.…”

In this study, four poly(diallyl dimethylammonium chloride) (PDDA) with different molecular weights are applied for forward osmosis concentration of high-salinity wastewater; meanwhile, the quantified effect of osmotic pressure and viscosity on the FO water flux is studied systematically. The 35 wt % PDDA (<100 kDa) solution could provide a water flux of 8.8 LMH with DI water as feed, and a water flux of 8.0 LMH with 15,400 ppm synthetic high-salinity wastewater as feed. Osmotic pressure plays a major and positive role in the FO water flux, while viscosity plays a secondary and negative role. Specifically, the FO water flux exhibited a variation of 115% using four PDDA draw solutions with the same viscosity and different osmotic pressures, while it showed a variation of 11.5% with the same osmotic pressure and different viscosities. The relationship of solute diffusion resistivity K and viscosity η was formularized for detailed discussion. The data of 28 polyelectrolyte solutions are summarized and demonstrate similar inference.

“…Based on the charge of the groups on the hydrophilic head, surfactants are mainly categorized as anionic, cationic, nonionic, and zwitterionic 9 . The hydrophilic part can improve the interaction with an aqueous phase, while the hydrophobic fragment can interact with a relatively hydrophobic membrane to create a hydrophobic layer on the membrane surface that avoids salt transmission, and therefore decreasing reverse solute flux 10 .…”

“…Various micellar draw solutions have been recently developed due to their unique features which affect the FO performance 10 , 15 , 16 . Among the different surfactants used as draw solutions, nonionic surfactants have not been investigated probably due to their low osmotic pressure and consequently low water flux.…”

Forward osmosis (FO) process has been extensively considered as a potential technology that could minimize the problems of traditional water desalination processes. Finding an appropriate osmotic agent is an important concern in the FO process. For the first time, a nonionic surfactant-based draw solution was introduced using self-assemblies of Tween 80 and choline chloride. The addition of choline chloride to Tween 80 led to micelles formation with an average diameter of 11.03 nm. The 1H NMR spectra exhibited that all groups of Tween 80 were interacted with choline chloride by hydrogen bond and Van der Waals’ force. The influence of adding choline chloride to Tween 80 and the micellization on its osmotic activity was investigated. Despite the less activity of single components, the average water flux of 14.29 L m‒2 h‒1 was obtained using 0.15 M of Tween 80-choline chloride self-assembly as draw solution in the FO process with DI water feed solution. Moreover, various concentrations of NaCl aqueous solutions were examined as feed solution. This report proposed a possible preparation of nonionic surfactant-based draw solutions using choline chloride additive with enhanced osmotic activities that can establish an innovative field of study in water desalination by the FO process.

“…The rapid growth of human population, urbanization, and industrialization have stimulated the over-extraction of water from the freshwater sources (e.g., river, lakes) for various purposes of the daily demands of water ( Mishra et al, 2016 , Misaghi et al, 2017 ). Moreover, the untreated waste water containing organic and inorganic compounds are generated from the domestic households, industries, agricultural runoffs, and are being discharged in the surrounding water bodies ( Sharma et al, 2016 , Cao et al, 2020 ) resulting in deterioration of water quality (WQ). The shortage of freshwater availability and deterioration of WQ has assisted in extinction of biotic communities and put excess pressure on ecology leading to disturbing the ecosystem ( Singh et al, 2019 , Singh et al, 2020a ).…”

The deteriorating water quality (WQ) of the sacred north-flowing perennial Indian River, Ganga was a serious concern in recent decades for population adjoining to the river and policy planners. The present evaluation attempts to assess the long-term (1989–2016) physiochemical characteristics of WQ of river Ganga at five upstream locations (Uttarkashi, Tehri, Rudraprayag, Devprayag, and Rishikesh) of Uttarakhand, India using comprehensive pollution index (CPI) and environmetrics (PCA and CA). These methods were used to categorize, summarize expensive datasets, and grouping the similar polluted areas along the river stretches. The WQ of river at all the locations were within the good category and most of the physiochemical parameters were well within their acceptable limit for drinking WQ. Considerably, CPI demonstrated the river WQ was in slight pollution range (CPI: 0.40–1.00) in the year 2007 and 2015 at all the five locations. The positive correlation coefficient (R 2 > 0.50) among NO 2 NO 3 , Ca, Na, B, and K indicates the significant contribution of organic and inorganic salts through runoffs from catchments due to weathering of rocks. PCA confirmed the input source of nutrients in the river from both natural and anthropogenic sources. Moreover, the upstream WQ assessed was found to be good as compared to the severely polluted downstream region. Due to COVID-19 and shutdown in the country, reduction of pollution load in the river was observed due to the rejuvenation capability of river Ganga. This information can assist the environmentalist, policymaker, and water resources planners & managers to prepare strategic planning in advance to maintain the aesthetic and cultural value of Ganga river in future.
