2.3. Membranes and modules for forward osmosis: 2.3.1. FO Membranes Generally‚ any dense‚ non-porous‚ selectively permeable material can be used as a membrane for FO. Such membranes have been tested (in flat sheet and capillary configurations) in the past for various applications of FO. In early studies‚ the researchers applied various FO membrane materials‚ including bladders of pigs‚ cattle‚ and fish; collodion (nitrocellulose); rubber; porcelain; and goldbeaters’ skin [36].

For example‚ when you put your instant coffee in boiling water‚ the coffee particles spread out and fill the entire mug‚ this is diffusion. A second way that substances can move through the cell membrane is by osmosis. This is a special type of diffusion where water moves from a high to a low concentration through a ’partially permeable
