- Metal plating industries generate large amount of wastewater containing heavy metals. Hard chrome process generates large amount of wastewater with high concentration of chrome. Wastewater from observed metal plating home industry contained 311,0914 mg/l Cr and 2,17 mg/l Ni. Chromium and nickel is dangerous metal, has high poison grade and have the character of carcinogenic of cancer cause. An experiment was conducted to separate the chromium and nickel from wastewater with ultrafiltration. Operation to separate of chromium and nickel was done in batch at room temperature. The influence of feed operating pressure and volume to flow rate of permeat, TDS from permeat, and turbidity (NTU) will be studied in this research, ultrafiltration has been observation is a effective process in separate of chromium and nickel. From knowable research that happened transformation of flow rate permeat UF at various dividing valves and happened transformation of turbidity (NTU) in permeat UF. At this research can be concluded that performance rejection of ultrafiltration membrane for reducing chromium is 99% and nickel is 98%. And performance rejection of ultrafiltration membrane for reducing concentration COD is 98%.
