Electro Coagulation offers on alternative to the use of metal salts or polymers and poly electrolyte addition for breaking stable emulsion and suspensions. The technology remove metals, colloidal solids and particles, and soluble inorganic pollutants from aqueous media by introducing highly charged polymeric metal hydroxide species. These species neutralize the electrostatic charges on suspended solids and oil droplets to facility agglomeration or coagulation and resultant separation from the aqueous phase. The treatment prompts the precipitation of certain metals and salts.
Electro Coagulation:
In its simplest form, on electro coagulation reactor is made up of on electrolytic cell with one anode and one cathode. When connected to on external power source. The anode material will electrically corrode due to oxidation, while the cathode will be subjected to passivation.
The CAK ECG system essentially consists of pairs of conductive metal plates in parallel, which act as monopole electrodes. It furthermore requires a DC power source, a resistance box to regulate the current density and a ammeter read the current values. The conductivity metal plates are commonly known as �Sacrificial electrodes�. The sacrificial anode lowers the dissolution potential of the same different materials.
Electro coagulation has successfully treated a wide range of effluents streams.CAK has focused on the application of electro coagulation to a particular situation. On-site optimization and process tuning had unlimited success.
