LOPROX®‚ (Low-Pressure Wet Oxidation) process for the treatment of industrial wastewater and sludge.

Typical fields of application include:

• Pre-treatment of highly polluted industrial wastewater streams (e.g. before being discharged into a biological treatment plant)
• Sludge treatment (e.g. sewage sludge)

Key element of the process is the homogeneous catalytic oxidation of organic matter with oxygen at elevated temperature and pressure. Characteristics are:

• Reaction in fluid phase (bubble column)
• Pressure range: 3-25 bar
• Temperature range: 120-220°C
• Oxidation with air or oxygen
• Catalyst: iron + co-catalyst
