1. A system for processing industrial waste water contaminated by volatile compounds and non-volatile salts and metal ions, comprising:
a) a regenerative thermal oxidation (RTO) unit, comprising a waste water inlet, a process air inlet, an RTO steam exhaust, an oxidizer, and heat exchangers disposed on the inlet and outlet sides of said oxidizer, adapted for pre-heating process air that enters said oxidizer with heat generated in said oxidizer; wherein each of said disposed heat exchangers reversibly operates as a hot heat exchanger for transferring heat to said process air entering said oxidizer and as a cool heat exchanger for being heated by hot exhaust exiting said oxidizer; and b) a vapor compression (VC) unit, coupled to said RTO unit steam exhaust, and comprising a steam inlet, a brine inlet, and a flash chamber; wherein said RTO steam exhaust is directly connected to and in fluid communication with said VC unit steam inlet, such that when operating, said RTO exhaust directs steam from said RTO unit into said VC unit steam inlet to provide energy for operating said VC unit to separate solids from incoming brine. |
