Laboratory Studies

The following are examples of organic destruction using EOD technology.  The studies were carried out in the
laboratories of ELTECH Systems Corporation, our licensor.  Spartan can carry out similar studies on your wastewater
samples (

Metal Working Fluid Wastewater

An unseparated electrolyzer was used to treat cutting oil wastes.  The pictures below show the reduction in turbidity
achieved with the ETC laboratory cell.  Detailed results can be found in
“Reduction of Biochemical Oxygen Demand and
Chemical Oxygen Demand of Metalworking Fluid Wastewater by Electrochemical Oxidation”, presented May 19, 2004 to
the Society of Tribologists and Lubrication Engineers, STLE Annual Meeting, Toronto, CAN
Electrolytic Organic Destruction Laboratory Cell
PHENOL

A parametric study was completed to determine the effects of current density, temperature, pH and phenol concentration
upon the rate of electrochemical oxidation.  The supporting electrolyte was 0.05M sodium sulfate. The rate of
electrochemical oxidation was monitored by measuring the change in the total organic carbon in the electrolyte as a
function of time.  The results are summarized in the Table below.
Parameter
Result
Temperature (25-50 degrees C)
Increased temperature increased electrooxidation by 50%
Current Density (15-50 ma/cm2)
Increased current density decreased rate of
electrooxidation
Concentration (50-500 ppm)
Increasing concentration increased the rate of
electrooxidation
pH (2-12)
Increasing pH increased rate of electrooxidation
