  • Client: Beijing Drainage Group
  • Solution: CambiTHP - B12

On 1st September 2014, Cambi was awarded the initial Beijing project, Gao Bei Dian, from Beijing Drainage Construction Company, a flagship for large-scale sludge projects with Cambi Thermal Hydrolysis Process (Cambi THP). The project finished in December 2016. The full sludge amount 99,100 tDS/y be treated in Cambi THP with subsequent advanced digestion in the existing 8 digesters (62,400m³) and the final dewatered cake (40%DS) to be used for land application. The biogas production is 67,000 m³ per day, generating green electricity around 56,000 Kwh/d. The plant serves a population of three million residents

  • Upgrading
  • 99,100 tDS/
  • New Cambi THP system with four lines, 20 Cambi THP reactors
  • Double Capacity of Existing 8 Digesters (62,400m³), 16 digesters original
  • Biogas Production of 67,000 m³/d
  • Start-up in Winter 2016
  • Mixed sludge organic content: 45-65%
  • Except biogas production of 60,000 m³/d (autumn) – PLAN
  • System output power generation: 56000 Kwh/d (after balance internal energy consumption)
  • Dehydration dryness content: > = 40%
  • Designed scale of Anammox: 800 m³/d
  • Adopt Sludge Concentration + Sludge Pre-dewatering + Cambi THP® + Anaerobic Digestion (medium temperature) + Filter Press Machine for sludge dewatering + Anammox
