Fouling

Interest in desalination using membrane processes has increased with the growth of membrane science and technology. Fouling of ion exchange membranes is one of the most significant considerations in the operation of the electrodialysis desalination process. The influence of the adsorption capacity o

Scaling and fouling of membranes are an on-going performance issue for most plants This presentation outlines innovations in speciality chemicals designed to inhibit membrane scaling and fouling and to clean membranes where deposition has occurred. There is an increasing trend to treat recycled wast

Fouling and scaling are the most serious problems in membrane processes. In sea/brackish water applications, pretreatment of RO feed water is the key step in designing the plants to avoid membrane fouling and scaling. Recent developments in pretreatment processes are more adapted to raw water qualit

The characterization of the flow inside an experimental flat membrane module with a smooth rotating disk was performed. The module consists of a disk rotating at speeds up to 3000 rpm inside a cylindrical housing equipped with a stationary circular flat membrane. The characterization was carried out

The main objective of this work was to determine the impact of various backwash scenarios on fouling in a pilotscale submerged membrane bioreactor (MBR) aerobically treating domestic wastewater. A total of seven different backwash scenarios were tested. The degree of membrane fouling was determined

This study investigated effects of the concentration of ball clay suspensions and different filtration modes on the fouling of a submerged module (YEF; Yonsei End Free). In a crossflow filtration mode, short filtration time could reduce the membrane fouling at the one-minute stop duration. In order

Membrane-based virus filtration is used in biotechnological processes due to advantages such as easy scaleup but is currently lacking standardized validation protocols. Thus, ultrafiltration (UF) of a rod-shaped virus was assessed to contribute to the body of knowledge regarding the characterization

This study aims to find a new die purification for wastewater reuse. It consists of the filterability of biological sludge exits of the wastewater treatment plant at Staoueli (Algeria) on porous membranes. The membrane used is a mineral membrane M2 Carbosep (15 Kg/mol). we are interested for the fir

Premix membrane emulsification (ME) is a specific ME process that combines low energy requirements with high permeate fluxes. Process conditions such as membrane type (polycarbonate, Nylon, polyethersulfone and cellulose mixed esters), transmembrane pressure (1–9 bar), number of emulsification cycle

Data are presented from a series of laboratory experiments designed to evaluate separation performance and humic acid fouling for two RO membranes treating brackish water at temperatures of 15, 25, and 35°C. A model is proposed that considers changes only to solute and solvent properties. Model resu
