In the study ...

  • Thermophilic sludge digestion pilot for Durban (SA)

    Thermophilic digestion of sewage sludge can increase the energy recovery at waste water treatment works (WWTW) to reach energy self-sufficiency. By increasing the digestion temperature to 52 – 55°C, higher efficiencies can be achieved. For a utility, this translates in potential additional income from electricity production by a CHP, lower polymer consumption and lower sludge disposal ...

  • Ammonia stripper pilot for digestate treatment AMFER in operation

    A system has been developed which facilitates removal and ammonia recovery from manure digestate. The digestate is heated and aerated batch wise in a process tank. The air which has become rich in ammonia is removed from the reactor, led through a condenser and further treated in an acid washer. In this washer the ammonia containing air is brought into contact with an acid washing liquid. During ...
