Assessment of Dissolved Oxygen in SewageContaining Camphor
2016
Camphor is widely used for odor eradication in
eateries and homes. The health of the sewage tank is paramount
to the environmental engineer as bacteria aid in sewage
degradation. This research is geared towards investigating the
effects of camphor on aerobic and anaerobic sewage degradation
due to its constant usage.
Ten 4 liters clean containers having 2 liters sewage where
prepared. To one set of four 4 liters containers which was not
covered (Aerobic), crushed camphor weighing (7.38g, 14.25g,
21.91g, and 25.75g) were added and the other four 4 liters
containers which was not covered (Anaerobic), camphor in solid
form (2No., 4No., 6No., and 7No.) with the same weight as
described above to check the effects of surface area and two
control containers having sewage alone. The pH, Total Dissolved
Solid (TDS), Dissolved oxygen (DO) and temperature was
observed and compared with a control solution which had no
camphor. From the research, dissolved oxygen level showed
significant decrease as the weight and number of camphor
increased. This could imply that the presence of camphor creates
a film over sewage thereby reducing oxygen exchange rate as it
was observed during the experimental process. This finding
could emerge as one of the reasons for septic tank failures which
may arise as a result of increased organic loadings over time.
However, the physio-chemical properties which include pH, TDS
and temperature
