Application of laser-induced breakdown-detection as a sensitive detector for UF membrane surrogate challenge tests
Characteristics of ultrafiltration membranes with respect to the removal of nanoscale particles can be determined by surrogate challenge tests (SCTs). Key elements of a successful SCT are the selection of a suitable surrogate and a reliable quantification method. A major challenge when using nanoparticles as surrogates is their quantification in the filtrate, since commonly used particle ...

Development of antifouling ultrafiltration membranes by surface modification
Poly(vinylidene fluoride) (PVDF) membranes were prepared by phase inversion technique. The effects of polystyrene (PS) concentrations on the blend membrane performance were investigated. The membranes were characterised in terms of shrinkage ratio, pure water flux, and porosity. The hydrophobicity of the membrane was modified by poly(vinyl alcohol) (PVA) through adsorption and crosslinking. The ...

AMONCOURT, France: Skid–Elimination of turbidity and microbiological retention
In 1988, the town of Amoncourt fitted out with first drinking water treatment plant using Ultrafiltration membrane process: the world first. The plant's planned operational life was 7 years. It will haveoperated to full satisfaction for 15 years. The site was specially monitored by the Ministry of Health. On the basis of these results, it gave sanitary approval to the clarification-disinfection ...

Fouling analysis of polysulfone ultrafiltration membranes used for drinking water treatment
Natural organic matter (NOM) plays a significant role in the fouling of ultrafiltration membranes in drinking water treatment processes. For a better understanding of the interaction between fractional components of NOM and polysulfone (PS) ultrafiltration membranes used for drinking water treatment, fouling and especially the physically irreversible fouling of natural organic matter were ...

Micellar-enhanced ultrafiltration for the solubilization of various phenolic compounds with different surfactants
Micellar-enhanced ultrafiltration (MEUF) was applied to the separation of phenolic compounds p-nitrophenol (PNP), p-chlorophenol (PCP), p-cresol (PC) and phenol (P) from effluents using a hydrophilic polyethersulfone ultrafiltration membrane. Cationic cetylpyridinium chloride (CPC), nonionic TX-100 and anionic sodium dodecyl benzene sulfonate (SDBS) were chosen as the surfactants. Several ...

Improvement of polyacrylonitrile ultrafiltration membranes' properties using decane-functionalized reduced graphene oxide nanoparticles
The effect of decane-functionalized reduced graphene oxide (decane-rGO) was studied on the performance of polyacrylonitrile (PAN) ultrafiltration membranes. The results showed that the decane-rGO/PAN membranes had greater salt rejections relative to their corresponding GO/PAN membranes, confirming superior performance of modified decane-rGO particles. Also, the membrane with 0.2 wt% ...

Effect of functionalisation on polysulfone-based ultrafiltration membranes
Polysulfone membranes possess excellent mechanical, biological and chemical stability but they suffer from fouling which leads to flux decline. Fouling can be minimised by functionalisation. In an attempt to overcome this limitation, the polysulfone was both sulphonated and carboxylated. The presence of sulphonic and carboxylic groups was confirmed through IR and NMR studies. Incorporation of ...
