Zooglea can cause foaming and bulking (poor settling) due to their thick polysaccharide (slime) capsules if present at a high enough abundance. Common control strategies zoogleainclude decreasing septicity, step feed, and lowering the F/M ratio. At low abundance, zooglea are not problematic as they are floc forming bacteria. At a high abundance, zooglea can cause foaming, bulking, and poor dewatering of sludge.
