Two Bacterial Isolates i.e. LT-5 and LT-6 Isolates Had High Flocculation Activity, With Activity of 68.92 and 71.38% Respectively. The Flocculation Activity of LT-5 Isolate Increased at PH 2.0-4.0 (acidic condition), However the Activity of LT-6 Increased at PH 6.0-8.0 (neutral). Addition of 0.05% of AlCl</span><span style="font-size:5pt;line-height:115%;">3 </span><span style="font-size:9pt;line-height:115%;">as Cation Was the Most Effective and Had Important Role in Flocculation Activity. Based on the Morphological Properties, LT-5 Isolate Was Identified As <em>Chromobacterium violaceum</em> and LT-6 Isolate Was Identified As <em>Citrobacter koseri.</em></span></Strong&gt;”.
