Chromic acid is a strong oxidizing agent and plays an important role in metal finishing and plating industry. Chromate containing waste effluents are toxic and carcinogen and their treatment is chemical, energy and cost intensive. Therefore, waste prevention and waste treatment are in the focus of attention since many years. However, recycling systems and alternative treatment methods have not gained general acceptance. This thesis investigates three technologies for the treatment of chromic acid solutions, which could combine economical and practical aspects with conservation of nature and natural resources.
