Abstract
A generalized approach to reverse osmosis process design is presented for solution-membrane operating systems characterized by the membrane parameters: hydraulic permeability L p, solute permeability ω 0, reflection coefficient σ, solute induced compaction coefficient β v, plasticizing coefficient of solute permeability β s; and mass transfer coefficient k on the high pressure side of the membrane and the properties of the solutions. Examples of reverse osmosis process design are carried out for ε-caprolactum concentration and sea-water desalination using PEC-1000 spiral wound modules and compared with the experimental data reported from TORAY and 800 m 3/day reverse osmosis seawater desalination plant at Chigasaki Beach by Water Reuse Promotion Center Japan.
