Table 5 collects some characteristic parameters of the semi-continuous activated sludge test. The Total Suspended Matter of the mixed liquor (MLTSM) largely exceeded the target value of the test guideline [8 ] on day 0 and day 1 (7.74 and 7.02 ). This was corrected by removing additional settled sludge. From day 2 until day 17, the MLTSM remained in the range of 2.11 g/1 (day 2) to 1.47 g/1... [Pg.174]

Samples of activated sludge efBuent were prepared in semi-continuous activated sludge (SCAS) units Blank = effluent from the SCAS unit Intermediate = feed to the SCAS unit containing 20 ppm C alkyidiphenyl oxide disulfonate (the effluent was confirmed to contain the previously identified major intermediate) alkyidiphenyl oxide disulfonate = effluent from the SCAS unit which was amended with surfactant at known concentrations. [Pg.163]
