Solar Drying of Effulent Treatment Plant (ETP) Sludge


  • Slow drying and putrefying of sludge at ETP plant.
  • High amount of wetness in sludge.
  • Dried sludge getting wet in monsoons

  • Design and construction of Solar Drying based on green house principles.
  • Enhance the rate of evaporation due to increased area for heat capture.
  • Vents and Turbo-ventilators to exhaust saturated air.
  • Use of forced draft to increase the rate of evaporation.
