Full textUltrafiltration (UF) of skim milk for standardization of the protein content for cheese making is a very common membrane process at industrial scale. However, fouling of the membranes with skim milk proteins causes a drop in productivity and constitutes a barrier to this process. Thus, the twice-daily cleaning/disinfection step is essential to restore the performance of the membrane and ensure health safety and product quality. It is generally carried out with alkaline and acidic formulated detergents, but it is also possible to use formulated enzymatic detergents which enjoy the reputation of being more effective. However, few fundamental studies exist on this subject, which this thesis aims to contribute to fill. The objective of this thesis was to develop new enzymatic detergents that are are effecient and compatible with the PES/PVP membrane widely used for skim milk UF. The target of the cleaning is a protein deposit. The approach was based on a methodology to aid the formulation of detergents based on the measurement of residual deposits on the membrane by ATR-FTIR: whether proteins, enzymes or other constituents of the detergents studied. Mutliple prototypes were formulated in collaboration with Kersia Company. Their evaluation followed 3 steps: i) rapid tests in a batch reactor (14 cm²) to select promising detergents according to their effectiveness in eliminating protein fouling, their cleanability and the integrity of the membrane in the short term, ii) transposition of promissing results under filtration conditions (127 cm²) also validating the filterability detergents, iii) finally, validation of detergent/membrane compatibility over the long term thanks to accelerated aging under microwave (3 cm²) and cleaning of the spiral wound membrane (6.8 cm²) for 52 hours

Full textMotivated by drinking water production plants reporting membrane failure issues, this study investigates the ageing of a commercially available PES / PVP UF hollow fiber. Proof is given that membrane degradation is mainly induced by sodium hypochlorite exposure. The effects on the PES chemical structure are limited, very low extend of chain scission occurs and the formation of an ortho-substituted phenol is observed as the main modification. Experiments show that the presence of PVP and/or PVP degradation products is a required condition for the PES oxidation to occur. On the other hand, PVP appears to be very sensitive to hypochlorite exposure. PVP radical oxidation mechanisms are identified presenting a maximal reaction rate for neutral to slightly basic pH and leading to the partial removal of the PVP degradation products from the membrane structure. Correlation of macroscopic and molecular characterizations demonstrates that PVP degradation is responsible for the membrane integrity loss (impairing selectivity and mechanical performance), while hypochlorite exposure also induces enhanced membrane / solutes interactions, leading to an accentuated fouling. The representativeness of static continuous hypochlorite exposure regarding the actual on-site membrane ageing is confirmed by the analysis of membranes extracted from an industrially operated module. Nevertheless, the hypochlorite dose parameter, widely used in the literature, is demonstrated to be inappropriate to describe the degradation rate: the hypochlorite concentration impact is shown to be dominating the exposure time impact on the degradation rate
