Introduction of Electrocoagulation
Electrodes (Aluminum, Iron, Stainless Steel)
The largest benefit of electrocoagulation is the environmental. The process limits the amount of waste and hazardous materials that are recirculated into ground and surface water.
The stabilized waste and processed water can be repurposed within the operations of the industry.
The process limits the amount of steps within the treatment process along with additives which increase operational efficiency while lowering cost.
Process can handle a wide variety of waste and particle sizes which might otherwise cause issues (wear/tear) during other processes.

The electrocoagulation of vegetable oil refinery wastewater (VORW) in a batch reactor with aluminum electrodes.
The operating parameters of the study were pH, current density, PAC (poly aluminum chloride) and Na2SO4 concentration.
Determine an efficient method to process organic waste, oils and greases, sulphates, and phosphates due to vegetable oil processing.

Goal of the study was to evaluate the removal of sulfate and COD from petroleum refinery wastewater using electrocoagulation.
Three types of electrodes were used for the study: aluminum, stainless steel, and iron.
The variables of the experiments were current density, electrode arrangement, electrolysis time, initial pH, distance between the electrodes and temperature.
The study also used two wastewater samples with varying levels contaminants. (WW-A and WW-B)
