Removal of lead from aqueous solutions by complexation ultrafiltration with chitosan
The removal of lead from aqueous dilute solutions by complexation-ultrafiltration with chitosan was studied. Experiments were performed as a function of aqueous pH, chitosan/Pb2+ ratio, and background electrolyte concentration. The value of pH was found to be the most important parameter to effect the lead removal. The lead removal rate reaches the plateau at almost 100% when the chitosan and ...

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 ...

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 ...

LAUSANNE, Switzerland: Grand Systeme–Elimination of turbidity and microbiological retention
The drinking water production plant in the town of Lutry (Vaud canton), on the edge of Leman Lake, was built in two phases (2000 and 2003). The plant supplies the city of Lausanne and the surrounding towns.Aquasource Ultrafiltration was chosen in order to integrate it in the best possible way into its environment. One final extension is possible for future ...

FROIDEFONTAINE, France: Skid–Elimination of turbidity, microbiological retention and elimination of organic matter.
The Froidefontaine intercommunal drinking water syndicate includes 9 towns and a total population of 1,630 inhabitants. The waters to be treated come from the Froidefontaine source at theedge of the Dessoubre river, at an altitude of 420 m.By nature and its supply basin, this resource of karstic origin has high variations in quality, notably in the organic and turbidity parameters. ...

APIE, France: Grand Systeme–Elimination of turbidity, organic matter, microbiological retention and metals treatment
The Apié Ultrafiltration plant was built to meet essential needs: doubling the consumption of drinking water during the summer period and the development of the region, which entails a greater water requirement.The water is captured at the Tanneron dam and routed to the treatment plant in the town of Peymeinade. This plant supplies the region of ...

GRANDVAUX, France: Ecoskid–Elimination of turbidity, microbiological retention and elimination of organic matter.
The two sources of Gorges and Coupet, with a dry weather flow of 400 m3/day, supply the region of St. Lupicin. The rest is provided by pumping from the “Abbaye” lake.The water has variable characteristics in terms of turbidity, microbiology and organic matter, that is why the Ultrafiltration by membrane process was ...

Biologically active ion exchange (BIEX) for NOM removal and membrane fouling prevention
The natural organic matter (NOM) removal efficiency and regeneration behavior of ion-exchange filters with promoted biological activity (BIEX) was compared to operation where biological activity was suppressed (i.e. abiotic conditions). The impact of BIEX pre-treatment on fouling in subsequent ultrafiltration was also investigated. Biological operation enhanced NOM removal by approximately ...

Influence of particle size and operating parameters on virus ultrafiltration efficiency
In water treatment, virus removal using ultrafiltration is a major step towards better water quality. In this paper, we study virus filtration efficiency using surrogate virus particles and via statistical surface-response approach. We focus on the effect of particle size (20–100 nm range) as a key factor along with the effects of transmembrane pressure (20–60 kPa range) and feed flowrate ...

All about ultrafiltration system, its mechanism, process, and application
An ultrafiltration system is based on numerous membrane filtrations, where pressure causes screening through a semipermeable membrane. In this method, the submerged solid particles and the solutes of greater mass are reserved within, and particles of low mass escape through membrane within the filtrate. Ultrafiltration system is widely used in various industries for water purification. These are ...

UF Membrane Technology
UF Membrane Technology Ultrafiltration (UF) is a variety of membrane filtration in which forces, such as pressure or concentration gradients, cause separation through the semi-permeable membrane. High molecular weight suspended solids and solutes remain in the so-called retentate while water and low molecular weight solutes pass through the membrane in the permeate (filtrate). The pore size of ...

Hybrid TiO2 photocatalytic oxidation and ultrafiltration for humic acid removal and membrane fouling control
Hybrid UV/TiO2 photocatalytic oxidation (PCO) and ultrafiltration (UF) process (PCO-UF) were used to remove humic acid (HA) and control membrane fouling. The PCO-UF process showed advantages in terms of higher removal rate of HA, higher permeate flux and less membrane fouling over UF alone and PCO alone on HA removal and membrane fouling control. Membrane material and pH of feed water were shown ...
