  • 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 ...

  • NuReSys-P applied DIRECTLY on Digested Sludge

    While up to now NuReSys-P has been applied on the centrate line, a test-run directly on the digested sludge line, showed an interesting extra ROI. The removal of PO4-P prior to hydro extraction, seems to show an improved dewater ability together with a decreased consumption of poly electrolyte. During the test-run on 5m³/h of digested sludge the original DM of 22% increased to ...

  • Using Dry Anaerobic Digestion to Break Down Food Waste

    The United State Environmental Protection Agency (USEPA) has a goal of 50% reduction in food waste to landfill by 2030. This means that of the 53 million tons of food waste disposed of in landfills, 26.5 million tons must be diverted. Compost and Anaerobic Digestion (AD) together process 2.7 million tons/year food waste – and most of composted tonnage is yard waste. This means that food ...
