TLDR
In this article, Humic substances were isolated from Penwhirn Reservoir (PR) and Esthwaite Water (EW) and their removal from solution by centrifugation was studied as a function of pH, humic concentration and molecular weight, and CaCl 2 concentration.About:

Adsorption of aquatic humic substances on hydrophobic ultrafiltration membranes
Catherine Jucker,Mark M. Clark +1 more
TL;DR: In this article, the interaction between Suwannee River humic and fulvic acids and ultrafiltration membranes is characterized by direct adsorption measurements, and the results show that the adsorbing capacity is smaller for fulvic acid than for humic acid.
Journal ArticleDOI
Mass transfer mechanisms and transport resistances in direct contact membrane distillation process
TL;DR: In this paper, the authors investigated the mass transport and fouling mechanism of direct contact membrane distillation (DCMD) process and found that molecular diffusion was the most suitable model for predicting fluxes of both laminar and turbulent flow.
Journal ArticleDOI
Ultrafiltration of natural organic matter
TL;DR: In this paper, the effects of surface water composition on rejection and fouling of two ultrafiltration membranes with different molecular weight cut-offs (10 and 100 kDa) were evaluated in stirred-cells.
Journal ArticleDOI
Microfiltration of colloids and natural organic matter
TL;DR: In this paper, the effect of natural organic matter (NOM) and humic substances (IHSS stream humic and fulvic acid reference material) on the deposition and rejection of inorganic colloids (hematite) by GVWP and GVHP microfiltration (MF) membranes was studied.
Journal ArticleDOI
Humic acid fouling in the membrane distillation process
TL;DR: In this article, the effects of pH, ionic strength, and divalent ion on fouling were studied with a 0.22-μm PVDF flat-sheet membrane in a direct contact membrane distillation unit.

Flocculation of dissolved organic and inorganic matter during the mixing of river water and seawater
TL;DR: In this paper, a new approach to estuarine studies is presented which establishes 1) the extent and salinity dependence of non-conservative behaviour; 2) composition and chemical form of removal products; and 3) abiological removal mechanisms.
Journal ArticleDOI
The adsorption of aquatic humic substances by iron oxides
TL;DR: In this article, the interaction of humic substances from Esthwaite Water with hydrous iron oxides (α-FeOOH, α-Fe2O3, amorphous Fe-gel) have been examined by measuring adsorption isotherms and by microelectrophoresis.
Journal ArticleDOI
Adsorption of natural dissolved organic matter at the oxide/water interface
TL;DR: In this article, it was shown that most of the acidic functional groups of the adsorbed organic matter are neutralized by protons from solution. But the organic coating is expected to have a great influence on subsequent adsorption of inorganic cations and anions.
Book ChapterDOI
Chemical Composition and Physical Properties of Humic Substances
TL;DR: The processes of humification occur mainly under aerobic conditions as mentioned in this paper, where animals that live in the soil may initially reduce the size of the fresh organic residues, and further transformations are promoted by the activity of the enzymes of the bacteria and fungi living in soil.
