Alternative methods of treating hospital wastewater can use a microfiltration membrane, where the results of the study show that the removal of oily wastewater reaches 82.5%, BOD 90%, COD 85% and total Coli up to 70%. In addition, it can remove particles from wastewater measuring 0.04 to 100 microns. The problem faced in the use of microfiltration membranes is the rapid occurrence of fouling / saturation on the surface of the microfiltration membrane causing the wastewater treatment operation time to not be long. The lack of time for this treatment causes the problem of a small amount of wastewater being treated and other problems, membrane replacement is faster. The purpose of this study was to determine the performance of silica sand as a preliminary treatment for microfiltration membranes to reduce the content of parameters pH, BOD, COD, TSS, Ammonia, Fatty Oil and Total Coliform of wastewater. The results of the study are as follows: 1) The average quality of hospital wastewater is temperature 28.8 C, pH 7, BOD 79 mg/l, COD 167.05 mg/l, TSS 68 mg/l, Ammonia 4 mg/l l, Phosphate 0.745 mg/l, Fatty Oil 1.64 mg/l, Coliform 2,200 MPN/100 ml. 2) The efficiency of reducing silica sand to parameters, namely for wastewater temperature 2.94%, pH 2.94%, BOD 78.24%, COD 56.25%, Total Solid Suspended (TSS) 75.85%, NH3 ( Ammonia) 56.49%, Phosphate (PO4) 39.13%, Oils and Fats 34.38%, and Coliform 27.27% MPN/100 ml.
