PROJECT DESCRIPTION
BACKGROUND
Currently, there is a lot of waste coming from different sources that must be treated in CPT-plants (chemical-physical treatment). The main problem for these plants is the wide assortment of waste. Even if the waste comes from only one supplier it is often composed of different types of waste in small volumes. Today no technology exists which can reduce the organic pollution in waste to be treated in CPT-plants.
OBJECTIVES
The main idea in this project is to treat waste with waste under conditions of electrolysis. The primary issue in this project is the engineering and the development of an additional module for waste treatment plants to reduce the organic content of waste (decrease of the COD-level) by oxidation with chromatic waste as a catalyst under the conditions of electrolysis. This technology will treat the filtrate of CPT-plants and aqueous waste. This would result in a reduction of organic compounds in sewage, a prevention of critical substances in waste waters such as complex building compounds, and a decrease in the use of chemicals.
RESULTS
50% average reduction of COD concentration; Reduction of all Chromium-(VI)Ions to Chroimium-(III)-Ions and separation as Cr-(III)-hydroxid; Improved AOX –reduction; Improved removal of organic compounds in the dewatered anorganic hydroxyd sludge50% average reduction of COD concentration; Reduction of all Chromium-(VI)Ions to Chroimium-(III)-Ions and separation as Cr-(III)-hydroxid; Improved AOX –reduction; Improved removal of organic compounds in the dewatered anorganic hydroxyd sludge
