Water quality analysis: Alter operation criteria, after the
system stabilized, water samples were taken from the
equilibration tank, and from the discharge outlet of each tank.
Analysis was conducted to obtain the pH, the temperature and
the concentrations of BOD5,
K 2C r2 O 7
COD , SStotal, NH4
+
-N, O
and G, and the true color, to demonstrate the treatment
efficiency of the proposed system.
