Add ferric chloride for precipitation in the sedimentation tank

I have a question: When ferric chloride is added to the sedimentation tank to adjust the pH to 5-6, the sludge becomes fine and settles very slowly. Is there any way to solve this problem? Would it be better to add pam?

For this, one can only try adding more. . You’re asking really tough questions—no mention of water at all.
