Electrocoagulation:
Electrocoagulation (EC) is an electrical process and has the capacity to destabilize emulsified oils, contaminants, metals, sub-micron particles. When contaminated water passes through the EC cells, the primarily negatively charged particles, combine with a positive charge from the cell plates, which initiates the coagulation process. The particles agglomerate into larger particles and either rise to the top or settle to the bottom of the water column.
The process is reported to be able to reduce or remove:
1. Heavy metals (including but not limited to: Copper, Zinc, Lead, Arsenic, and Hexavalent Chromium)
2. Turbidity, TSS, Bacteria, Phosphorus, Oil De-Emulsification, COD (Chemical Oxygen Demand)
3. BOD (Biochemical Oxygen Demand), PCB's, Sulfides
Pressurized versions of the EC process may also keep O2 and H2 gasses contained in the treating cell where they contribute to the water cleaning process and then when discharged from the cell help to cause the flocculants to float to the top of the water. These are the cells currently used by Water Cleaning Services LLC.
