Abstract (en)
[origin: EP1052004A1] Waste waters are sprayed (4) over perforated panels (3). Warm air at 25 to 45 degrees C (5 and 5') is drawn through the perforations, and facilitates evaporation. The warm air is produced by combustion of biogas produced during waste degradation. Effluent is recycled (9) until it reaches the desired concentration. An independent claim is included for equipment to carry out the process.
