2.3. Suspended solid settling experiment
Batch tests to investigate TSS settling characteristics
of starch factory wastewater under quiescent condition was carried out in a settling column of 10.0 cm diameter
and 2.0 m height for different TSS concentrations.
Wastewater of a desired TSS concentration for settling
experiment was prepared by diluting the concentrated
wastewater with tap water. The wastewater was poured
into a settling column after stirring thoroughly. Samples
from top of column were collected at different time
intervals ranging from 2 to 60 min and analyzed for TSS
concentration.
