The reaction to make polycarbonate generates a byproduct brine stream. The byproduct stream has retained value that can only be claimed if its quality is improved via the removal of various compounds including TOC (Total Organic Carbon). The current study investigates the treatment of such brine streams containing high ppm levels of organics. Examples of these compounds include sodium gluconate, BPA, TEA, sebacic acid, methylene chloride, and others.

The purification of the brine samples is done via the introduction of the solution on NORIT GAC 830R activated carbon bed.

Both batch and continuous modes of operation are presented in this work. The resulting brine stream is suitable for use in an electrolysis reaction to produce chlorine and caustic soda
