Oil & Grease Removal Using Human Hair Waste (HHW)

'Oil and Grease Removal Using Human Hair Waste (HHW)'. Oil and grease can
give serious impact towards envirofifiient like ilfioXic water, which cause damage to
the aquatic life due to depleting in oxygen content in water. The objective of this
research was to determine the feasibility of human hair waste (HHW) to remove oil
ilfid grease from oil tefiliety wastewater. HHW was collected from hili saloon at
Pusing, Perak while the wastewater was collected from oil refinery at Kerteh,
Terengganu. The effect of various dosages of HHW and contact time on removal of
oil and grease from oil refinery wastewater were evaluated by batch studies. 100 mL
of prepw-ed WMteWI!ter s!Jmple was filled illto cortical fiasks. HHW wa& added into
each conical fiask at various dosages ranging from 10000 mg!L- 50000 mg!L. The
samples were then agitated using the orbital shaker at various contact times of 3, 6,
9, 12, 15, 18, 21, 24, 48, 72, 96 l!lld 120 hours. After end of each contact time, those
samples were filtered and test for oil and grease concentration. The highest oil and
grease removal of 78 % was achieved at 30000 mg!L dosage of HHW at 24 hours
contact time, while the maximum removal was achieved by 71 %with 50000 mg!L
dosage ofHHW at 21 hours of contact time. The adsorption isotherm yield by HHW
is Freundlich isothertii ili1d Pseudo second order kinetic model HHW proved to be
fea&ible in removing oil and grease.
