Reverse osmosis membrane technology trends

When possible, the intermediates are used for the subsequent manufacture of other intermediates or dyes without drying because of saving in energy costs and handling losses. This trend is also apparent with dyes. The use of membrane technology with techniques such as reverse osmosis to provide pure, usually aqueous, solutions of dyes has become much more prevalent. Dyes produced and sold as liquids are safer and easier to handle and save energy costs.

Focusing on the recent advances and updates, this section addresses new development in chemical and pharmaceutical industries and in the conservation of natural resources. Included in this edition are newer practices and technologies and their applications or trends for future applications with relevant references that have appeared in the literature since the first edition was published. Several new chapters on emerging areas such as membrane separation in petrochemical oil refinery, chitosan as new material for membrane preparation, new membrane material for ultrafiltration (UF) and nanofiltration (NF), and potential application of reverse osmosis (RO) in chemical industry have been added in the second edition.
