The present work aimed to study the efficiency of nanofiltration (NF) and reverse osmosis (RO) membrane for heavy metal removal from wastewater and study the factors affecting the performance of these two membranes: feed concentrations for heavy metal ions, pressure, and flow rate. The experimental results showed, heavy metals concentration in permeate increase with raise in feed concentrations, decline with increase in flow rate. The raise of pressure, heavy metals concentration decreases for RO membrane, but for NF membrane the concentration decrease and then at high pressure increase. The rejection percentage for chromium in NF and RO is 99.7% and 99.9%, for copper is 98.4% and 99.3%, for zinc is 97.9% and 99.5%, for nickel is 97.2% and

The results revealed that adding 0% (than db in the CT) ( treatment A ) control gained high significan different than that of other adding percentages in texture and appearance . And showed that of adding 5% (than db in the CT) (treatment B ) gained high significan different than that of other adding percentages in flavor , colour and overall acceptance. The adding 15% (than db in the CT) ( treatment C) showed that gained high significan different than adding 25 and 35 % (than db in the CT) (treatments D and E ) than all sensory properties .
