... the real conditions of membrane use during filtration process. Desalination 146 (2002) 149–154 Adsorption of lysozyme on membrane material and cleaning with non-ionic surfactant characterized through contact angle measurements M.C. Kaplana, A. Jégoua, B. Chaufera*, M. Rabiller-Baudrya, M.C.
Desalination 146 (2002)

The cleaning of an ultrafiltration polyethersulfone (PES) membrane fouled by skimmed milk was studied by ATR–FTIR showing the functional groups of foulin ...

... units, particularly when raw water is drawn from an open sea intake. Membranes tend to foul slowly, which makes it necessary to perform periodic cleanings with physical and chemical products, which in turn produce a decrease in the useful life of the membranes. The specific objective of the researc ...
Desalination 139 (2001)

... and the development of a new system. During this period, the RO research program evaluated the performance of ten different seawater membranes, cleaning and restoration techniques and procedures, using various potential agents. Furthermore, computer aided design program and process design an ...

... during time. Fouling is the most important problem associated with the application of membranes. A strategy for membrane regeneration is chemical cleaning of the fouled membranes. One of the major applications of reverse osmosis membranes is processing of water from different resources or for variou ...

... in solution concentration is observed to have a varying impact on the permeate flux. 0.2 wt% caustic solution gives the best performance for cleaning the fouled membranes. The performance of 30 kDa ultrafiltration membranes was investigated during the process- ing of whey protein concentrat ...

... resides. In this paper clean water flux results were combined with dye tests (Amido black) to reveal how clean the membranes really were after cleaning with both formulated and industrial cleaners. The dye tests not only identified the remains of protein foulant on the membrane after cleaning bu ...
Desalination 214 (2007)

... this autopsy. In-depth study was achieved at 50°C for PES membrane ageing in alkaline, acid, alkaline chlorine oxidant and a commercial alkaline cleaning solution (Ultrasil 10). The PES membrane appeared stable in all solutions except those containing chlorine. It was shown by FTIR-ATR that the C ...

... and cleaned with sodium hydroxide and Ultrasil 11 (Henkel Ecolab) over several operational cycles until a steady-state was reached. Fouling and cleaning mechanisms were evaluated using Fourier Transform Infra Red (FTIR) spectral peak heights, zeta potential and contact angle measurements.
Desalination 175 (2005)

... approaches to slow down the membrane fouling rate. Two such approaches were discussed in this study, namely: (1) off- site chemical and mechanical cleaning, and (2) air scouring. A longer subsequent operation time was observed after a membrane was cleaned chemically compared with mechanically. For ai ...
