Figure 3 shows the SS concentrations during each
treatment process for the four sampling days. Analytical
results indicated that the SS concentration 0.4–
407.2 mg/L. Wastewater samples A3 and A5, which
came from the bottom of concentrated liquid wastewater,
had a high SS concentration and large
variation. Sample A3 and A5 in the latest three and
two samplings exceeded effluent standards for SS
concentration. Based on effluent standards for water
treatment plants in Taiwan, the SS concentration
should be
