Design and Development of Composite Nonwoven Filter for Pre-filtration of Textile Effluents Using Nano-technology

摘要

The main aim of this study is to test the feasibility of using composite membrane of nonwovens and Nanofibre for the pre-filtration treatment of reactive dye bath effluent from the textile industry. The results of ultraviolet spectrophotometer of filtered and non-filtered sample show that the cleaning efficiency of effluent water will be achieved in the range of 70-80%. Cleaning efficiency of the Nano-filter filter remains around 70%. But a composite nonwoven filter made up of polyester fibre needle punched nonwoven and Nano-fibre web; the cleaning efficiency can reach as high as 90%.
