| 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 water way system is used for waste water facility; the result of this
makes most of the plants surrounding it found dead Inaddition, with the substandard construction
of water ways for waste water causes the water polluted. The domestic waste using dual filtration
of active carbon and kapok is used in this 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 dual filtration of active
carbon and kapok media.
The research is done using dual bed filtration of active carbon and kapok which has
0.3 meter and 0.15 meter thickness with length and width 25 each, total height 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 of sample taking started from 0, 30, 60, 90, 120 and 150 minutes with
debit 2,25 Lperminute. The sample taking of waste 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 and grease in the water gravitically SKSNIM-68-1990-03.
Based on the result of laboratory analysis, it proves 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 the 90 till 150 thminute. This is because of the kapok hasreachedits highest level.
