Study on Turbid Water from the Grand Canal by Flocculation

Flocculation is a simple and inexpensive means of water treatment. Combination of the inorganic flocculant as polyiron sulfate and the organic polymer flocculant as AN934SH 、FO4440SH 、FO4498、FO4650SH is utilized. The results show that it remarkably improves the flocculating ability of suspensoids compared with adding flocculant separately and the sequence of adding flocculants is important to the process of flocculation.
