Future Trends

Emerging reverse osmosis applications in the food industry are reported to be in dairy processing, sweetener concentration, in juice and beverage processing, production of low-alcohol beer and wine, and waste stream processing [35]. For ultrafiltration, the prospect of future applications in the food industry is excellent according to Eykamp [36], who states that many applications in broad food areas are based on the ability to change protein and starch/sugar, salt and water ratios. Longer term prospects include refining of oils. Applications will be widespread and increase with technical progress and customers' acceptance. Future applications for microfiltration appear also to be excellent [37]. Many applications in broad food areas are based on the ability of microfiltration to retain micro-organisms without affecting desirable properties. Applications are predicted to be large, but the growth rate slow.
