- In the modified granular activated carbon (modified AC) hydrogen peroxide as a catalyst.
- Resistant to acid, the reaction rate, without adjustment of pH, low system cost of implementation.
- Compared to current methods, without adding chemicals such as HCl, Cl2 and so there will not be a by-product.
After Piranha Clean (SPM) cleaning process emissions of sulfuric acid containing hydrogen peroxide recovered after use
