The waste (water) streams resulted from the production of (bio) ethanol / alcohol can be treated by means of anaerobic technology.

The effluent streams produced by the different production processes are influenced by a great number of parameters such as, process designer, milling process (dry or wet milling), raw material.

The condensate, the whole stillage, the thin stillage as well as the spend grain waste (water) streams are ideal substrate for anaerobic treatment. HydroThane UASB, EGSB and SWD are technologies applicable for these industries.
