Comparison of nanofiltration and tight ultrafiltration membranes in the filtration of paper mill process water
... permeability. These data were used to explain the experimental results with effluents and to choose the possible membranes for the paper mill process waters. Comparison of different membranes in the constant pressure filtrations showed that usually the membranes with high pure water permeabilit ...

Treatment of dairy process waters by membrane operations for water reuse and milk constituents concentration
... to a purification station or collected to be spread on land. The very few works, that have been dedicated to the treatment of the so-called process waters (flushing waters, first rinse waters or “white waters”), show that nanofiltration (NF) or reverse osmosis (RO) is adequate for th ...

... large water consumption. The present work was related to investigations about practices of water management of 11 dairy plants. Treatment of the process water produced in the starting, equilibrating, stopping and rinsing processing units was proposed to produce water for reuse in the plant and t ...

Nanofiltration and reverse osmosis of model process waters from the dairy industry to produce water for reuse
In dairy plants the process waters generated during the starting, equilibrating, interrupting and rinsing steps contribute to the production of effluents. They correspond t ...

Application of forward osmosis for reducing volume of produced/Process water from oil and gas operations
... of the key challenges faced by the oil and gas industry globally. Speciﬁcally, the gas industry in Qatar is challenged to minimize the produced/process water (PPW) volumes injected into disposal wells to ensure long term sustainability of the reservoirs. This research evaluated a novel applicatio ...
