Popis:	El-Salaam canal water in Sinai, Egypt is a mixture of agricultural drainage water and Nile water. The canal water is characterized by remarkable monovalent, divalent and trivalent ions and moderate total dissolved solids (TDS) (1300–2400 mg/L). Biologically the raw water is characterized by the existence of total coliformand pathogenic bacteria. The present study is concerned with the treatment investigation of El-Salaam canal water by using pilot plant low pressure nanofiltration (LPNF) and low pressure brackish water reverse osmosis (LPBWRO) membrane separation units to produce water for irrigation and drinking purposes. Hence, the raw water is allowed to be pretreated by using 2.5 mg/L nonionic polymer for coagulation then followed by nanofiltration (NF) separation to produce water of quality suitable for irrigation or followed by brackish water reverse osmosis (BWRO) to produce water of quality suitable for drinking purposes. The LPNF treatment system removed 82% of the TDS, 71–74% monovalent ions and...
