The concept of smart water supply grids has emerged as a promising response to the evolving challenges faced by traditional systems. Traditional systems are grappling with sustainability such increasing main breaks, diminishing freshwater resources, untraceable non-revenue usage, and escalating demand. condition worsens in arid- or semi-arid regions which also suffer from scarcity due harsh climate effects, surface inaccessibility, loss, over-exploitation. Smart infrastructure consists...
TFN-NF membranes prepared by<italic>in situ</italic>interfacial polymerization of branched polyethyleneimine and trimesoyl chloride, with simultaneous impregnation as-synthesized hexagonal wurtzite nano-ZnO either through aqueous or organic phase.
A novel polysulfone–cerium oxide (Psf–ceria) mixed-matrix membrane (MMM) with enhanced γ radiation resistant property was developed. Ceria nanoparticles were synthesized by gel-combustion route and then various concentrations of ceria (0.1–2% Psf) incorporated in the polysulfone matrix to synthesize Psf–ceria MMMs. Radiation stability membranes checked doses 100, 500, 1000 kGy. characterized X-ray diffraction (XRD), photoelectron spectroscopy, small-angle scattering (SAXS), transmission...
Thin film composite (TFC) type positively-charged nanofiltration membranes, bearing fixed quaternary ammonium moieties, have been developed and studied. Branched polyethyleneimine (PEI) was functionalized by reaction with glycidyl trimethyl chloride (GTACl) to introduce chloride. Positively-charged TFC membranes were prepared in situ interfacial polymerization of PEI terephthaloyl The effects variation chemical compositions other experimental conditions such as curing temperature duration on...
Uranium and vanadium are valuable trace metals in seawater. The economic viability of recovery these depends on development efficient sorbents. radiation induced graft polymerization technique was adopted this study to prepare metal chelate embedded polymers sheet form order investigate the heavy from seawater, using different nonwoven substrate materials. In obtain more direct information grafting levels, parametric studies see influence cumulative dose, retention time air, surrounding...
Nanotechnology is a potential augmentation to the existing water purification technologies. Four different types of functional nanomaterials, like carbon nanotubes, metal/metal oxide nanoparticles, dendrimers and zeolites, are currently under evaluation for application. Nanomaterials offer excellent opportunities because high surface area (surface/ volume ratio), but challenge build up an integrated scalable system. Membranes, being energy-economic having ability get associated processes as...
<italic>In situ</italic>impregnation of nanostructured reduced graphene oxide (nRGO) in Ps matrix leads to Ps–nRGO composite UF membranes with promising attributes such as improved flux, optimum selectivity along reasonable thermal and mechanical stability.
Crosslinked polyacrylamides were synthesized by solution polymerization using benzoyl peroxide as the radical initiator. The water–insoluble polymer obtained was functionalized reacting with hydroxylamine to convert amide group into hydroxamic acid group. resultant characterized in terms of moisture uptake, elemental composition, IR spectra, thermal stability, exchange capacity and heavy metal sorption. sorbent, particulate form, investigated for its sorption properties respect uranium from...
