Confirmation of the correlation between membrane fouling in microfiltration and biopolymer concentrations in various Japanese surface waters

by IWA Publishing  (Apr. 8, 2015)

A variety of surface waters used for drinking water sources were collected from different parts of Japan to investigate a correlation between the concentration of hydrophilic biopolymer (e.g. proteins and polysaccharides) in the feed water and membrane fouling in microfiltration. Hollow-fiber membranes made from polyvinylidene fluoride with a ...

Application of laser-induced breakdown-detection as a sensitive detector for UF membrane surrogate challenge tests

by IWA Publishing  (Apr. 8, 2015)

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 study on chemical adsorption of dissolved oxygen on naturally formed co-oxides filter film in aqueous solution: combined characterization of XPS and TPD

by IWA Publishing  (Apr. 8, 2015)

The chemical adsorption of dissolved oxygen (DO) by co-oxide filter film-coated sands, formed through the filtration of ground water containing high concentrations of ammonia, manganese and iron, were studied. The results showed that the filter film consisted of silicates, carbonates, manganese and iron oxides and was constructed in a ...

Characterization of modified PVDF membrane by gamma irradiation for non-potable water reuse

by IWA Publishing  (Mar. 27, 2015)

Poly(vinylidene fluorine) (PVDF) membranes were grafted by gamma-ray irradiation and were sulfonated by sodium sulfite to modify the surface of the membranes. The characteristics of the modified PVDF membranes were evaluated by the data of Fourier transform infrared (FT-IR), X-ray photoelectron spectroscopy (XPS), field-emission scanning ...
