Treatment of Textile Industry Wastewater by Sequential Hybrid Processes Photo-Fenton, Ultrafiltration (UF), Reverse Osmosis (RO) and Recovery of some Dyes, Salt and Perfluoroalkyl Sulfonate from the Retentate
Author(s): Delia Teresa Sponza*
Textile industry waste water should be treated by best available and economical hybrid treatment techniques (BAT) to achieve the discharge limits (ELV) set by European Union, and reuse them as process or irrigation waters. Recovery of some valuable materials/chemicals and reuse of treated waste water is a European Union Directive (European Commission). When the industrial wastewaters are not treated by the best available techniques, it is not possible to reuse the water and recover some valuable chemicals. Therefore, in this study a sequential photo-Fenton/UF/RO process was used to treat the COD, COD-dis, DOC, colour salt and reuse of treated textile wastewater and recovery of some economical merits from the retentate of the RO (dyes, salt and perfluoroalkyl sulfonate). The photo-Fenton experiments were carried out in a cylindrical pyrex thermostatic module with a volume of 2,5 L, 1,8.. View more»
