Electrocoagulation Water Treatment Process

Electrocoagulation (EC) technology is based upon a process generally referred at as “adsorption and co-precipitation”.   The electrocoagulation water treatment solution offers an alternative to the use of metal salts or polymers and poly-electrolyte additives for breaking stable emulsions and suspensions in wastewater recovery and wastewater treatment streams.   The electrocoagulation process removes metals, colloidal solids and particles, and soluble inorganic pollutants from wastewater recovery and wastewater treatment streams by introducing highly charged polymeric metal hydroxide materials.   These materials neutralize the electrostatic charges on suspended solids and oil droplets to facilitate coagulation resulting in separation from the wastewater recovery and wastewater treatment streams.  

Electrocoagulation Equipment

Ecolotron’s patented electrocoagulation equipment, the E-FLOC® Electrocoagulation Reactor, consists of a number of heavy solid metal plates serving as electrodes.   Heavy metals cannot be directly induced into a biological reactor because it kills the reactor’s microorganisms.   As the highly pressurized wastewater flows between these electrodes a chemical oxidation-reduction reaction occurs causing the hazardous metals to chemically attach itself to the plates non-hazardous metal.   The result is both metals in their combined state can be removed from the resulting solution.   The removal of these metals through our electrocoagulation equipment allows the remaining wastewater to be processed through a biological reactor for a further reduction in pollutants thereby permitting discharge into the environment. 

Ecolotron developed the E-FLOC® Electrocoagulation Reactor through extensive engineering design and process refinement.   The E-FLOC® Electrocoagulation Reactor applies best engineering practices to a formally outdated process.  These advances take the electrocoagulation process to a “state-of-the-art” technology capable of producing consistent and dependable results in wastewater recovery and wastewater treatment applications.  Electrocoagulation systems are becoming the wastewater recovery and wastewater treatment method of choice due to the many benefits and advantages of our technology.

Ecolotron, Inc.’s patented high-pressure electrocoagulation systems & equipment, the  E-FLOC® , offers the following benefits while overcoming the shortcomings of previous electrocoagulation applications:

Benefits of Electrocoagulation Systems & Equipment for Wastewater Treatment

Reduced Treatment Cost

– utilizes low cost electrolysis to accomplish treatment, eliminating the need to dispose of hazardous by-products of chemical treatment.

Dependable Results

– predictable concentrations of metal in the effluent which are lower than those attainable with chemical precipitation treatment.

Easily Maintained

– designed to be user friendly minimizing both operator attention and costly maintenance downtime.

Eliminates Chemical Reagents

– in most cases, or simply requires pH adjustment and poly-electrolytes to enhance liquid-solids separation.

Lower Capital Costs

– system designed to easily retrofit existing treatment infrastructure while improving performance, reliability and lowering operating costs.

Multiple Contaminates

– electrocoagulation process is capable of treating multiple contaminates of differing  pH simultaneously, eliminating the need to segregate wastewater streams.

Reduced Footprint

– reduced tank capacity requirements and other ancillary equipment for associated mixing and metering of chemical reagents.

Sludge Minimization and Stabilization

– electrocoagulation generates a stable, easily dewatered sludge that routinely passes the USEPA TCLP for RCRA metals.
