Title
Geopolymers for hazardous cations and anions inertization
Conference Dates
May 27-June 1, 2018
Abstract
Several waste liquors are classified as toxic or hazardous waste and represent a real burden for companies in terms of costs and treatment time. One of the most difficult to treat is the tannery waste water that represent a high pollution risk if not treated and collected properly.
Geopolymeric matrix based on metakaolin has been used to treat tannery waste water without any post use treatment. The as received waste water containing tannins, chromium soluble salts, phenols, bicarbonates, and a mixture of organic compounds have been added to a geopolymeric formulation which was optimized for Cr+3 liquor [1].
