Membrane fouling in osmotically driven membrane processes: A review
TL;DR: A comprehensive review on membrane fouling in ODMPs with a focus on the elaboration of the factors and mechanisms governing the fouling behavior is provided in this paper, where a general osmotic-resistance filtration model is presented to assist in the interpretation of the intrinsic interrelationships among those fouling factors and mechanism.

Colloidal interactions and fouling of NF and RO membranes: A review
TL;DR: The mechanisms and factors controlling colloidal fouling of both RO and NF membranes are reviewed and major colloidal foulants (including both rigid inorganic colloids and organic macromolecules) and their properties are summarized.

Biofouling in reverse osmosis membranes for seawater desalination: Phenomena and prevention
TL;DR: In this paper, the causes, consequences and control of biofouling in RO membranes used for seawater desalination are discussed in some detail: biofilm formation, role of EPS, and sequence of events leading to bio fouling.
Journal ArticleDOI
Role of extracellular polymeric substances (EPS) in biofouling of reverse osmosis membranes.
TL;DR: Control fouling experiments with EPS in sodium chloride solutions supplemented with 0.5 mM calcium ions indicate that calcium increases the adsorption efficiency of polysaccharides and DNA by 2- and 3-fold, respectively, which resulted in a significant decrease in permeate water flux.

Biofouling of spiral-wound nanofiltration and reverse osmosis membranes: A feed spacer problem
Johannes S. Vrouwenvelder,D.A. Graf Von Der Schulenburg,Joop C. Kruithof,Michael L. Johns,M.C.M. van Loosdrecht +4 more
TL;DR: In both spiral-wound nanofiltration and reverse osmosis systems biofouling is dominantly a feed spacer problem and control should be focused on the development of low fouling feed spacers and hydrodynamic conditions to restrict the impact of biomass accumulation on the feed channel pressure drop increase.

Colorimetric Method for Determination of Sugars and Related Substances
TL;DR: In this article, a method was developed to determine submicro amounts of sugars and related substances using a phenol-sulfuric acid reaction, which is useful for the determination of the composition of polysaccharides and their methyl derivatives.

Critical flux concept for microfiltration fouling
TL;DR: The concept of critical flux is introduced in this article to identify the critical flux and the desirability of starting filtration operations at a low flux, where a flux below which a decline of flux with time does not occur.
