A continuous process is described in which a combination of low and high retention membrane modules is applied. Such a combination can give higher production rates and lower product losses than conventional hyperfiltration processes. Moreover it gives the possibility to concentrate solutions to osmo

## Abstract We propose simple expressions $\Pi /\Pi \_0 = 1 + (\varphi /\varphi \_{{\rm ex}} )^{3\alpha - 1}$ and $(\delta \_0 /\delta )^2 = 1 + (\varphi /\varphi \_{{\rm ex}} )^{2\alpha }$ for the osmotic pressure ฮ and the depletion thickness __ฮด__ as a function of the polymer concentration __ฯ__
