Catalytic Ozone Oxidation: Breaking Down Refractory COD Without Iron Sludge — the Hydroxyl Radical Factory for Industrial Wastewater Advanced Treatment
Catalytic Ozonation
Catalytic Ozone Oxidation: Breaking Down Refractory COD Without Iron Sludge — the Hydroxyl Radical Factory for Industrial Wastewater Advanced Treatment
Nationwide (coal chemical, coking, petrochem, pharma, dyeing)
Pilot to full-scale (10s–10,000s m³/d)
Catalytic ozonation (HCOP) uses ozone plus metal catalysts to generate hydroxyl radicals that break down refractory COD without iron sludge. Covers ozone utilization, the O₃/COD ratio and catalyst life.

Electro-Fenton: On-Demand Hydrogen Peroxide Generation at the Cathode — an Advanced Oxidation Tool for Recalcitrant Industrial Wastewater
Electro-Fenton
Electro-Fenton: On-Demand Hydrogen Peroxide Generation at the Cathode — an Advanced Oxidation Tool for Recalcitrant Industrial Wastewater
Nationwide (dyeing, pharma, petrochem, coking, leachate)
Pilot to full-scale (10s–10,000s m³/d)
Electro-Fenton (EF) generates H₂O₂ in-situ via cathodic O₂ reduction and electrochemically regenerates Fe²⁺, upgrading the classic Fenton reaction into a self-sustaining oxidation loop.

Persulfate-Activated Advanced Oxidation (PS-AOP): Sulfate Radical SO₄·⁻ Tears Apart “Recalcitrant” Organics — One More Tool for Industrial Wastewater Advanced Treatment
Persulfate AOP
Persulfate-Activated Advanced Oxidation (PS-AOP): Sulfate Radical SO₄·⁻ Tears Apart “Recalcitrant” Organics — One More Tool for Industrial Wastewater Advanced Treatment
Nationwide (coking, petrochem, dyeing, electroplating, paper, leachate)
Pilot to full-scale (10s–1,000s m³/d)
Persulfate (PDS/PMS) activated by heat, Fe²⁺, Co²⁺, UV or carbon generates sulfate radicals (SO₄·⁻) that oxidize recalcitrant organics over a wider pH range than hydroxyl radicals. Covers mechanisms, removal rates and comparison with Fenton/ozone.
