with set A, only added air-flow is best treatment way when
compared with water sample after treatment with set B and C
in all parameter except BOD parameter that the water sample
after treatment with set B had efficiency more than set A and
C. Although the water sample after treatment with set B and C
had trend to same direction, the water sample after treatment
with set B had efficiency more than the water sample after
treatment with set C in all parameters. Moreover, the odor,
clarity and color were observed. It can be seen clearly after
treatment in two weeks such as odor was disappeared, color
starts to clear and more transparent through the second week
of the trial
