Andrew, I do know that the zinc (Galvanizing) will rapidly dissolve in mild caustic or acid. It may be safe enough for clarifier use if the entire solution is between a pH of about 6 to 9, but I would use extreme caution as any unreacted acid or base will dissolve the zinc and contaminate the batch. Perhaps someone else can advise you on the pH's of the phases at the clarification stage, or if they have tried this before.
