Advantageous sorption/Capillary rejection– membrane layer is heterogeneous as well as mini permeable, as well as electrostatic repulsion happens as a result of different electrostatic constants of solution and membrane. Option diffusion– NF system is uniform as well as non-porous, and solute as well as solvent liquify in the active layer of the membrane and also the transportation of the solvent happens because of the diffusion through the layer. Billed capillary– electrical double layer in the pores determines denial. Ions of same charge as that of membrane layer are brought in as well as counter-ions are rejected due to the streaming possibility. NANOFILTRATION FOR TEXTILE EFFLUENT TREATMENTFabric wastewater treatment for industrial reuse stays as a challenging issue because of numerous factors. Among them, Biological Oxygen Demand (FIGURE), Chemical Oxygen Need (COD), Total Dissolved Solids (TDS) content of the wastewater and also Nonbiodegradable nature of natural dyestuffs existing in the effluent are the main obstacles.
