Aquapure I-200 is a sulfated, liquid, ferrous/aluminum cationic coagulant. It is superior in settling suspended solids. It is generally used in conjunction with an anionic flocculant but in some cases can work without the use of a flocculant. Aquapure I-200 may be used in an alkaline precipitation of metals or in combination with a metal precipitant like Aquapure P 601 or Aquapure T-500. Aquapure I-200 works particularly well precipitating out zinc to very low levels.
