Research of technology treatment of Zn-Fe sludges coming from zinc chloride production

Project goals

Zn-Fe sludges originating in the production of zinc chloride (by recycling of waste dezincing bath from hot dip galvanizing plants) are nowadays unworkable wastes and their disposal as an hazardous waste must be performed. This procedure endangers environment as well as whole waste baths recycling system. Some solution consists in the development of new treatment technology of treatment of the sludges to obtain useful product.

    Výzkum technologie zpracování Zn-Fe kalů z výroby chloridu zinečnatého

  • Annotation in Czech

    Zn-Fe kaly vznikající při výrobě chloridu zinečnatého (recyklací odpadní odzinkovací lázně z žárových zinkoven) jsou v současné době nezpracovatelný odpad a musí se vyvážet na skládku nebezpečných odpadů, což ohrožuje jednak životní prostředí a jednak celý systém recyklace odpadních lázní. Řešením je proto vyvinout novou technologii zpracování těchto kalů tak, aby bylo možné jejich další efektivní využití.
