| Abstract |
The purpose of the research was to observe the behavior of organic colloids in the presence of polymeric flocculants and the ionic salts NaCl, NaClO4, and Ca(ClO4)2. The study was defined in terms of the flocculation kinetics and the absolute turbidity. In the flocculations of corn starch, and tannic acid the presence of the calcium ion greatly accelerated the rate of flocculation, and chloride ion had a slight disruptive effect on floc formation. The flocculation studies were confirmed by refiltration rate experiments where the floc sizes were determined. The flocs with calcium ion were the largest and those with chloride the smallest.
