sludge treatment

CEIT has wide experience in the design of WWTP sludge treatment with the following features:

  • Analysis of new technologies
  • Capacity and stability improvement of sludge digesters


    Automatic control strategies

  • Co-digestion with industrial sludge
  • Sludge valorisation

    Biological methane production

    Soil restoration

It is worthwhile to mention that CEIT employs a methology based on the following points:

  • Experimentation (pilot and full-scale)
  • Mathematical modelling and simulation
  • Optimisation of process design and operation

Examples of R&D projects

  • Mesophilic and thermophilic anaerobic digestion
  • Autothermal Thermophilic Aerobic Digestion (ATAD)
  • DUAL digestion (TAD+AD) for sludge treatment in Navarra
  • Pretreatments for increasing the capacity of anaerobic digesters
  • Automatic control of aerobic and anaerobic digestion
