Patent ID: 7947170

Claim:
An apparatus for treating a waste chemical mechanical polishing (CMP) fluid or a waste electrochemical mechanical polishing (ECMP) fluid used in a substrate processing system, comprising: a conduit system configured to be coupled to the substrate process system to received the waste CMP fluid or ECMP fluid from the substrate process system; a holding tank containing a supply of waste CMP fluid or ECMP fluid coupled to the conduit system; an oxidizing agent cell coupled to the conduit system and in fluid communication with an oxidizing agent source, wherein the oxidizing agent cell is configured to provide an oxidizing agent to the waste CMP fluid or ECMP fluid from the oxidizing agent source to break down chelated metal complexes in the waste CMP fluid or ECMP fluid and to remove organic materials from the waste CMP fluid or ECMP fluid; an organoclay filter cell coupled to the conduit system and comprising an organoclay media, wherein the organoclay filter cell is configured to remove carbon containing material from the waste CMP fluid or ECMP fluid; an active carbon filter cell coupled to the conduit system and comprising an active carbon media, wherein the active carbon filter cell is configured to remove carbon containing materials and halogen species from the waste CMP fluid or ECMP fluid; and a resin column coupled to the conduit system and comprising an anion exchange resin, wherein the anion exchange resin is configured to remove metallic ions from the waste CMP fluid or ECMP fluid.
