Penurunan Kadar TSS (Total Suspended Solid) dan Minyak Lemak (Fatoil) Limbah Cair pada Pengolahan VCO (Virgin Coconut Oil) dengan Filtrasi Menggunakan Bed Karbon Aktif dan Kapuk

Abstract

The water pollution occurs due to the side product or waste produced by the VCO Industry is not properly managed. The waste water as the side product of VCO process happened since it is assumed that the waterway system is usedfor waste water facility; the result of this makes most of the plants surrounding itfounddead Inaddition, with the substandard construction ofwater waysfor waste water causes the water polluted. The domestic waste using dualfiltration ofactive carbon and kapok is used inthis research. The objective of this research is toprove the capability and efficiency of dual media filtration reactor in reducing TSS concentration and oil grease in the liquid waste of VCO Industry. And also to prove if there is any variation change of TSS concentration reduction andoilgrease at each period of time against dualfiltration ofactive carbon and kapok media. The research is done usingdual bedfiltration of active carbon and kapok which has 0.3 meter and 0.15 meter thickness with length andwidth 25 each, totalheight 108 cm. The waste water is kept inthe storage basin which is mixed with lime water. Then, the sample of waste water is run into the reactor which is gravitically dropped on the adsorbent (active carbon) then to kapok media. The variation ofsample taking startedfrom 0, 30, 60, 90, 120 and 150 minutes with debit 2,25 Lperminute. The sample taking ofwaste water was done at the outlet I (active carbon) and outlet II (kapok) then to be analyzed atLaboratory, for TSS parameter is inline with SK SNI M-03-1990-F quality test method of water physics, for grease oil Standard 62 test method of oil content andgrease in thewater gravitically SKSNIM-68-1990-03. Based onthe result oflaboratory analysis, itproves that there is a significant reduction of TSS concentration with average reduction efficiency 47.42% at the 90th minute till the 150th minute. For oil greaseconcentration goes on increasing with increase average efficiency 26.24% at the90 till 150thminute. This is because of thekapok hasreachedits highest level.
