This project led to the development of the proprietary high surface area electrode, the Multilayer Mesh electrode (MLM). The MLM electrode overcame some of the restrictions of limiting current density on mass transfer. It also led to the development of the ETC 48 electrolyzer. This essentially marked the beginning of the Electrolytic Organic Destruction (EOD) technology.
Sixteen skid-mounted ETC 48 electrolyzers were installed in the Czech Republic for the Diamo project. These electrolyzers were the foundation of the ETC cell design that would be used later for organic destruction. A picture of three ETC-48 on one skid is shown above.
Two systems, each capable of oxidizing 4 lb/hr of formate and 2 lb/hr of oxalate at 2 and 1 wt% respectively, were supplied. Field performance verified the lab and pilot testing.
Pictures of skid-mounted EOD units for DuPont are shown below.
