Title: Method and apparatus for fluid treatment by reverse osmosis under acidic conditions
Inventor: MUKHOPADHYAY DEBASISH
IPC: B01D61/04
Filed: 2002-11-06
Abstract: A process for treatment of water via membrane separation equipment (Fig.2). A feedwater (10) is maintained or adjusted to a pH of 4.3 or lower, and fed to a membrane separation system. In this manner, species such as TOC become more ionized, and (a) their rejection by the membrane separation process is significantly increased, and (b) their solubility in the reject stream from the membrane process is significantly increased. Passage of TOC through the membrane is significantly reduced. A recovery ratio of eighty percent (80%) or higher is achievable with most feedwaters, while simultaneously achieving a substantial reductio in cleaning frequency of the membrane separation equipment. The method is particularly useful for the preparation of high purity water (54).
