The performance of restaurant wastewater treatment by using zeolite nanofiltration membrane

Zeolites are commonly used as membrane material because they are easily available as natural form. Many zeolites are found in volcanoes. Zeolite can be used as a nanomembrane material with pore size about 0.001µm. The purpose of this study is to find the rejection value and the best flux value that can be produced used restaurant wastewater. Variation of concentration that used were pure wastewater mixed with tap water using ratio 100%, 75%: 25% and 50%: 50%. On restaurant wastewater, the highest flux value on each variation of concentration 100%, 75% and 50% are 7,64 L/m². hour, 11,89 L/m². hour and 13,59 L/m². hour. The highest rejection value of turbidity was reached 88,84% for 100% concentration, 70,00% for 75% concentration and 77,50% for 50% concentration.
