Siemens to install water treatment plant at ethanol facility in Thailand

• 

Siemens has been awarded a $10 million contract from Advance Agro Ethanol, a subsidiary of Advance Agro Public Co. Ltd., to provide process and electrical equipment for a wastewater treatment plant at AAE's ethanol plant in Thailand. The system includes pretreatment, using filter press technology to remove suspended solids; pre-acidification; anaerobic digestion; aeration; secondary clarification; dewatering; chemical dosing units; and a biogas flare stack. Biogas generated from the wastewater is expected to save AAE more than $5.5 million per year for a three-year return on investment.
