Fouling is the accumulation of unwanted material on solid surfaces. The fouling materials can consist of either living organisms (biofouling, organic) or a non-living substance (inorganic).

Fouling mechanism is generally defined as the deposition of undesired materials (solid particles in the feed stream, ions, and biological materials) on the membrane surface and inside the pores, resulting in lowering the permeate flux over time [143] which increases the cost of produced water [144].

In the present study, we propose a simple and straightforward multiple linear regression model to describe the piecewise succession of five pore-blocking/cake-filtration fouling mechanisms during the full filtration process, based on the idea of the linear additivity of filtration volumes under different fouling mechanisms.

This paper aims at summarizing the new research progress of membrane fouling mechanism, control, prediction and detection in the MBR systems. Classification, mechanism, influencing factors and control of membrane fouling, membrane life prediction and online monitoring of membrane fouling are discussed.

Membrane fouling is a process whereby a solution or a particle is deposited on a membrane surface or in membrane pores in a processes such as in a membrane bioreactor, [1] reverse osmosis, [2] forward osmosis, [3] membrane distillation, [4] ultrafiltration, microfiltration, or nanofiltration [5] so that the membrane's performance is degraded.

Fouling is a membrane separation phenomenon resulting from several mechanisms: precipitation of sparingly soluble salts, adsorption, cake or gel formation, and pore blockage. Fouling is often divided into external and internal fouling, depending on where the foulant is deposited.

Apr 4, 2019 · Hereby, we attempt to review the different types of fouling in forward osmosis, cleaning and control strategies for fouling mitigation, and the impact of membrane hydrophilicity, charge and morphology on fouling.

In the current work, we critically reviewed the fouling mechanisms affecting factors of fouling such as the size of particle or solute; membrane microstructure; the interactions between membrane, solute, and solvent; and porosity of the membrane and also examined cleaning methods of microfiltration (MF) membranes such as physical cleaning and ch...

Aug 11, 2022 · Fouling is the deposition of material on the heat transfer surface which reduces the film heat transfer coefficient. The impact of fouling on the heat exchanger is manifested as...

This phenomenon is commonly termed as membrane fouling, which refers to the blockage of membrane pores during filtration by the combination of sieving and adsorption of particulates and compounds onto the membrane surface or within the membrane pores.
