1. Techno-Economic Analysis of Dye Separation in Textile Recycling
University essay from Lunds universitet/Avdelningen för Teknisk vattenresursläraAbstract : This study determines the technical and economic feasibility of separating dye from a process filtrate in industrial textile recycling using electrocoagulation or sequences of membrane filtration with microfiltration, ultrafiltration, nanofiltration and reverse osmosis. The lower requirements for treating this stream, compared to previously researched dyehouse effluents, left treatments not good enough for dyehouses viable for this process filtrate. READ MORE
