| dc.description.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. | en_US |
