Abstract

Laundry waste is often thrown into the environment without going through previous processing. While the content in laundry wastewater can pollute the environment. One way to minimize the content in laundry water is to use membranes from zeolite and PVA (polyvinyl alcohol). We can know the performance of the membrane by looking at the value of flux and rejection. The use of membranes as filters still has fouling problems. Fouling occurs because of the accumulation of material that is stuck on the membrane. This research was also conducted to determine the levels of COD and BOD in laundry wastewater after filtration using PVA membranes. In the application process carried out with a variation of pressure 3,4,5 bar and the concentration of laundry wastewater 100%, 75%, 50%, 25%. The results showed that the type of PVA membrane was ultrafiltration with a permeability value of 47.31%, density 1.8 gr / cm3, porosity of 32.2% and water absorption of 17.91%. Flux decreases with increasing operating time and the rejection value ranges from 86% - 97%. The type of fouling at the concentration of laundry wastewater 100%, 50% and 25% is the cake / layer formation while the concentration of laundry wastewater 75% is complete blocking. PVA membranes can reduce the COD and BOD content in laundry water with a decrease in COD ranging from 83.10% - 93.90%; BOD ranges from 72.75% - 92.06%
