The numbers I gave you were tested without polymer. I used a commercial sand filter after a clarifier which used polymer for removing heavy metals like Cu. In that project, Cu was tested as ND. However, we did not test for SDI or TSS. Therefore, you must test your theory before concluding that it does not work.
