• Innovative process for sewage sludge disintegration and volume reduction:
  • 85% reduction of organic dry matter
  • Significant improvement of dewatering properties
  • Cost-efficient alternative to incineration

• Destruction of persistent organic compounds (e.g. pharmaceuticals, pesticides, PAH, phenols, ...) and wastewater detoxification
• Autothermic operation possible for most applications
• Cheap and environmentally friendly catalyst
• Salt concentration up to 20 % allowed
• Proven reliability and mastery of materials and corrosion questions (reaction columns with up to 18 years running time without replacement)

This diagram illustrates the typical course of reaction within the LOPROX® process applied to a poorly biodegradable wastewater containing chlorinated aromatic compounds. Chemical oxygen demand (COD) and adsorbable organic halogens (AOX) are used as parameters indicating the degree of pollution. With increasing reaction temperature, both parameters are greatly decreased, AOX even more so than COD.

Simultaneously, biological oxygen demand (BOD) rises and thus the BOD/COD ratio increases drastically from its initial value of < 0.1 to values noticeably higher than 0.5.

The BOD/COD ratio gives an indication of the biodegradability of a wastewater. Wastewater with a BOD/COD ratio > 0.5 can usually be cleaned well in biological treatment plants.
