Study of the ultrafiltration rate of a membrane based on polysulfone modified by the OGTAPMDA epoxy resin on colored waters by the indigo and the red cibacrone.

The textile industry is one of the most chemically intensive industries on earth and it is the main polluter of drinking water. This industry generates huge amounts of complex chemical substances in the unused materials including coloring agents in the form of waste waters during the various stages of textile processing.In this work, we prepared the membrane having mechanical properties and improved hydrodynamics. For this task, we modified the polysulfone with synthetic epoxy resin Octaglycidylether tetra-aniline para of methylenedianiline (OGTAPMDA)
