Hydrogen Peroxide Removal Technology｜Modified Granular Activated Carbon Catalytic System
This technology utilizes modified granular activated carbon (modified AC) as a catalyst for hydrogen peroxide (H₂O₂) decomposition. It offers high chemical compatibility, fast reaction kinetics, and low system implementation cost. The system is well suited for treating H₂O₂-containing waste streams in advanced semiconductor, TFT-LCD, optoelectronic, and chemical manufacturing processes, effectively reducing downstream treatment load and improving overall water recycling efficiency.
Technical Features
- Modified granular activated carbon catalysis: Uses modified AC as a highly efficient and stable catalyst for rapid H₂O₂ decomposition.
- High acid resistance: Capable of direct operation in strong acid environments, including high-concentration sulfuric acid, without pH adjustment.
- No additional chemicals required: No need for additives such as HCl; no generation of chlorine gas (Cl₂) or other hazardous by-products, ensuring safe and environmentally friendly operation.
- Low system cost: Simple process flow with minimal equipment requirements, making it ideal for retrofitting and upgrading existing process lines.
Applications
- Piranha Clean (SPM) recycling systems: Suitable for sulfuric acid recovery and regeneration after SPM cleaning processes containing residual H₂O₂, significantly improving chemical utilization efficiency.
- CMP / wet etching wastewater treatment: Effectively removes hydrogen peroxide, reduces biological toxicity, and enhances wastewater recycling performance.
