2.3 Experimental procedures
2.3.1 Optimal media ratio in a modified grease trap
Proportion of media in a modified grease trap was
set from bottom to upper layers. The arrangement of
media was 5 cm diameter of Mon brick, 1 cm diameter
of gravel and 3 cm diameter of Mon brick,
respectively. The arrangements of media ratio were
1:1:1, 1:1:2, 2:1:1, 1:2:1, 2:2:1, 2:1:2 and 1:2:2. The
thickness of media arrangement (three layers) was
calculated at 30% of the modified grease trap’s height.
A 600 L of domestic wastewater was filled into the
modified grease trap which fixed with specific
arrangement of media ratio. The flow rate was
controlled at 2 L/min and 6 hrs of HRT. The
experiment was conducted in triplicate for each
arrangement of media ratio.
