Solutions for (bio)ethanol / distilleries

The waste (water) streams from the production of (bio)ethanol or ethanol spirits are generally very suitable for anaerobic treatment, due to their organic compounds.

The effluent streams produced by the different production processes are influences by a great number of parameters such as, process design, milling process, type of raw material, etc. This requires special attention in the design of the treatment plant for this type of industry.

Typical streams from these industries that can be treated are:

• Whole stillage
• Thin stillage
• Spent wash
• Vinasse
• Condensate from evaporator.
The Upflow Anaerobic Sludge Blanket (HydroThane STP® UASB) process and the External Circulation Sludge Bed (HydroThane STP® ECSB) process from HydroThane are worldwide proven processes for the treatment of this type of waste water.
