Treatment of dairy process waters by membrane operations for water reuse and milk constituents concentration
In the dairy industry non-accidental losses of milk or dairy products to sewer amount to 1–3% of the total milk processed. These significantly contribute to the 0.5–6.0 g COD/L of end-of-pipe waste-water. The major part of this polluting charge originate ...

Characterisation of cleaned and fouled membrane by ATR–FTIR and EDX analysis coupled with SEM: application to UF of skimmed milk with a PES membrane
The cleaning of an ultrafiltration polyethersulfone (PES) membrane fouled by skimmed milk was studied by ATR–FTIR showing the functional groups of fouling species and EDX coupled with SEM measuring the atomic composition. Two kinds o ...

Limiting flux in skimmed milk ultrafiltration: impact of electrostatic repulsion due to casein micelles
The variations of the limiting flux during skimmed milk ultrafiltration were studied under various physicochemical environments (pH, ionic strength, chemical nature of added salts). The evolutions wer ...

Nanofiltration and reverse osmosis of model process waters from the dairy industry to produce water for reuse
... waters generated during the starting, equilibrating, interrupting and rinsing steps contribute to the production of effluents. They correspond to milk products (milk, whey, cream) diluted with water without chemicals. The treatment of these dairy process waters by nanofiltration (NF) or revers ...
