Textile water recycling by means of bio-flotation and uv irradiation treatments


The European finishing industry produces 6 million tons per year of textile materials, with a consumption of 100 litres of water per kg of product. This industry is an high consumer of waters. Water is reducing and its availability will be the key-factor of success for many sectors. Moreover, higher and higher environmental standards about the textile effluents reflect on increasing management costs for water treatment. So, the water recycling has to become a versatile and efficient process. Biological treatments are insufficient to attain the requested quality for water. Boil-UV studies a new process composed by a bio floatation treatment of dyeing waters, followed by a oxidative process employing hydroxyls obtained via UV proteolysis of the hydrogen peroxide. The project aims to investigate the decolouring process, to develop UV energy-saving sources, to provide an expert system controlling the decolourisation process. A prototype will be set up to test technologies and attain 75% in recycling of wastewaters of textile finishing mills.
