Because of ITO (Indium Tin Oxide) related metal and metal oxide coating, it must be regularly asks equipment materials maintenance vendors implemented surfaces of equipment components washing of regeneration work. However, before the cleaning of regeneration operations, attached metal and metal oxide coating on the equipment components must be removed and clear; while in waste clearing the way there are six major types, namely: enterprise has cleared and re-use self-clearing agency, undertakings entrusted clear legal transportation, reuse agency entrusted legal transport Clear, utilities commission licensed waste clearance permits public and private institutions clear, reuse agency entrusted licensed waste clearance permits public and private institutions clear. Traditional way is to soak by acid treatment, referred to it as “liquid” with indium tin waste, but its derivative acidification and corrodes surface of aluminum or stainless steel body components, resulting in shortening the life of the work piece is costly problem, and its due aluminum, iron, chromium, nickel and other heavy metals that generate additional corrosion of the body, the section also causes the high cost of processing and disposal problems; less injury to the body development, but also effectively remove physically coating, for percussion (high-pressure water jet) and sandblasting the surface of metal or metal oxide falling; waste sources will therefore be incurred as follows: indium tin oxide sputtering regular maintenance of equipment components renewable surface cleaning operations before blasting through percussion and outputs " wastes containing high concentrations of indium tin “and the acid output via the wastewater treatment sludge is also rich in indium-tin compounds, referred to as” solid “with indium tin waste. This method produces indium-tin-containing waste, able to handle recycling technology has been developed through the use of, and the terminal waste sludge treatment due to improvement in the source, you can avoid waste containing indium tin copper in the TCLP control , chromium, cadmium, lead, barium, mercury, arsenic, selenium, hexavalent chromium, its treatment standards since the “hazardous waste”, promoted to “general industrial waste”, to increase the competitiveness of enterprises to reduce costs, but also To fulfill its corporate environmental responsibility.
