This video demonstrates the power of Electrocoagulation and the ability to destruct hexavalent chromium without using reducing chemicals. Eletro-coagulation is able to treat hexavalent chromium directly. This process also offers the advantage of producing very little sludge compared to conventional method of treatment. The sludge produced is also non-leachable.
This type of wastewater contains a fluorescent dye that is commonly used during nondestructive testing. A type of inspection process commonly used in the Automotive and Aerospace industries. This process is used to detect small cracks in critical components. The water shown in the video is water from the rinsing process. This water contains the fluorescent dye which is commonly removed by filtration or encapsulation by bentonite clay to absorb the dye penetrant oil.
