ELECTROCOAGULATION
Electrocoagulation has reduced contaminated water volume by 98%; and lowered the treatment cost by 90% for bilge water containing heavy metals and oil emulsions
(Gilmore 1993)
The electrocoagulation process marketed by E.A.R.T.H. Company Limited. is based on valid scientific principles involving responses of water contaminants to strong electric fields and electrically induced oxidation and reduction reactions. This process is able to take out over 99 percent of some heavy metal cations and also appears to be able to electrocute microorganisms in the water. It is also able to precipitate charged colloids and remove significant amounts of other ions, colloids, and emulsions. When the system is in place, the operating costs including electric power, replacement of electrodes, pump maintenance, and labor can be less than $1 per thousand gallons for some applications. Potential applications to agriculture and quality of rural life include removal of pathogens and heavy metals from drinking water and decontamination of food processing wash waters.
Key Benefits:
- The reduction of bacteria from 110,000,000 (standard plate count) in sewage waste water to 2,700 bacteria per milliliter;
- Can Be Used To Treat The contaminants in oily waste waters from steam cleaning operations, refineries, rendering plants, and food processors are generally reduced 95 to 99%;
- Dissolved silica, clays, carbon black, and other suspended materials in water are generally reduced by 98%;
- Heavy metals in water such as arsenic, cadmium, chromium, lead, nickel, and zinc are generally reduced by 95 to 99%.

The following well documented lab and field tested results are routinely attained through electrocoagulation. To determine these parameters Hach DR 4000 method was used. These ranges were determined using USEPA and NIST standards.
