Among membrane separation processes [Crespo, 1994; Li, 2008; Field, 2017] osmotic driven techniques are considered as innovative potential industrial methods, although the principle of these procedures has been known for long. Their wide industrial application is, however, hindered by mainly technical difficulties (e.g. the lack of proper membrane materials). In this chapter two promising osmotic membrane processes are presented, where forward osmosis and membrane osmotic distillation were applied for up-concentration of a coconut milk solution and juices obtained from various colourful wild fruits, respectively.
