PERFORMANCE ANALYSIS OF SMALL SCALE DESALINATION PLANT BASED ON MULTI TRAY AERATOR, MEDIA FILTER, AND SEAWATER REVERSE OSMOSIS

Seawater as abundant source for clean water is deemed impossible task, particularly in developing country. Therefore, the feasibility of applying reverse osmosis technology, coastal area drinking need further investigation. This paper aims to design and analyze performance small-scale desalination plant using combination multi tray aerator, media filter, multiple membranes consisting ultrafiltration, brackish, seawater membranes.Parameters used verify small are salinity total dissolved solid membranes, while parameters examining pre-treatment Fe Mn. The test results will be evaluated under regulation minister health, Permenkes No. 32/2017. influence pump pressure on flow also analyzed.The result shows that can reduce concentration significantly from 10,200 ppm 16 ppm, or 99.84%. ratio rejected 36%. However, bacteria E. Coli still found water, which probably caused by biofouling.
