Usually hot lime softening is employed for this application for influent clarification. It does an excellent job of macro silica removal down to 1-3 ppm in the treated effluent, if the pH is maintained in the specified range. Hot lime softeners, however, are notorious for having to be maintained quite a bit. Hope this helps. Thanks, Sean

If you need to get to lower silica, then I would recommend RO. There really isn't an effective chemistry for precipitation for filtration until you get into the RO membrane micron size.
