The present work aimed at exploring viable performance and cost effective treatment for upgrading secondary treated wastewater (STWW) for potential reuse in numerous applications. The results of the field survey targeting some selected wastewater treatment plants in Egypt indicate a total potential for wastewater reuse approaching 5.2 million m 3/d. Moreover treatment efficiencies ranged from (86.9 % 92.8 %) , (87.3 % - 96.5 %) and (89.5 % - 96.9 %) for BOD, COD and TSS, respectively. In this thesis, a short cut prediction model enables estimation of the NF membrane rejection (removal values) for each specific membrane cut - offs (200 1000 Dalton). The results of these empirical models have been validated using reported data from pilot and large NF wastewater upgrading systems which qualifies the empirical functions for planning and feasibility studies and also as an integral part of decision making process
