Cation Dependence, pH Tolerance, and Dosage Requirement of a Bioflocculant Produced by Bacillus spp. UPMB13: Flocculation Performance Optimization through Kaolin Assays

Table 3

Statistical analysis for flocculating activity at 0–20% cation dosage.

Dosage; (%)	Flocculating activity; (%)	𝑃 value*	Homogenous subset**
0%	63.9 ± 0.98	𝑃≤0.05	a
5%	83.5 ± 1.86	𝑃≤0.05	b
10%	86.8 ± 1.81	𝑃>0.05	c
15%	86.7 ± 1.91	𝑃>0.05	c
20%	89.6 ±0.70	𝑃>0.05	c

* The mean difference between groups is significant at 0.05 level.
** Homogenous subset is in ascending manner from lowest to the highest mean value.
