Abstract:

An earlier paper by the authors (1988) introduced a correlation between the Vesilind settling parameters, V_o and K, and SVI performed in a stirred, 1-L graduated cylinder even though SVIs also were determined in more commonly used containers such as an unstirred, 1-L graduated cylinder and an unstirred, 2-L Mallory settlometer. Only the stirred graduated cylinder relationship was given because stirring increases the precision and decreases the variability of the SVI test, and Standard Methods (1975) has included stirring in the SVI test since 1975. Nonetheless, because the SVI test continues to be performed in unstirred containers, the correlations for the other SVI test methods measured during the study are presented herein so that they can be used by the wastewater treatment plant operations community.
