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 ...

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 ...

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 ...

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 ...

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 ...

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 ...
