· CMP wastewater. Simulation predicted that 1,000 ppm of ammonia in the waste would cause the treated water to exceed discharge limitation unless a very high pH set point was used. The process simulation software was used to support the development and design of a process to treat Cu CMP wastewater, which was successfully piloted and commercialized.

· In addition, CMP generates 30–50 L of waste slurry per 200 mm wafer [1921, ]. After CMP, the wastewater containing water, various chemicals, and slurry particles is disposed of after removing the particles through electrodecantation and electrocoagulation. Details of the CMP wastewater treatment are described in Chapter 3.

CMP waste water treatment for semiconductor production. During planarization of the wafer surfaces, waste water is generated that contains grinding aids and mostly copper ions from the removed copper coatings. The used slurries and auxiliaries lead to high concentrations of solid particles in the waste water.
