Avivid Water Technology has developed a revolutionary stand-alone water purification technology called Turbo-Coag©. Our breakthrough process unlocks the true potential of a proven 100+ year old idea known as Electrocoagulation (EC). EC should become the system of choice to treat many types of waters contaminated with emulsified oils, heavy metals, poorly settling solids and poorly soluble organisms that add turbidity, odor and color the water.
In Electrocoagulation systems, contaminated liquids pass over electrically charged plates creating a reaction which causes the contaminants to be precipitated as solid sludge. EC can treat water contaminated with emulsified oils, poorly settling solids, water suspended clays, and poorly soluble organisms that add turbidity, odor and color to water. Microorganisms are killed in the process of EC treatment. Heavy metals and soluble organic compounds are removed. The effluent will be substantially free of suspended solids odors, turbidity, heavy metals, microorganisms, particulates, volatile organics, polymers, pharmaceuticals and other such contaminants. The treated water can frequently be used with no further processing.
Electrocoagulation has been an "emerging technology" since the late 19th century, when many electrical and magnetic treatments were attempted. The first US patents on electocoagulation were awarded about 1909. Significant, ongoing worldwide work on the science of EC consistently support the potential efficacy of the process. EC is not widely used however since developing an EC reactor into a robust industrial process requires resolving serious issues of electrochemical cell design, electrode fouling, power supply and operating conditions. Avivid Water Technology has a solid technical response to these challenges.
A typical EC reaction is diagrammed below.
Current is passed through a metal electrode (typically iron or aluminum) oxidizing the metal to its cation (here Al+++ but iron may also be used in the form of Fe+++). Simultaneously, water is reduced to hydrogen gas and hydroxl ions (OH-). The process introduces the metal cations directly into the water electrochemically using sacrificial anodes. This reaction replaces common chemicals used for purifying water. A strong floc is produced creating a concentrated sludge which will settle or float that is easily removed with various proven technologies.
