2. Use:
As flocculant in water purification and sewage treatment, with good decolorizing, deodorizing effect. It can remove oil, bacteria, algae and reduce COD, BOD and heavy metal. Suitable for treatment of low-turbidity, low-algae, low-temperature, low-contaminated water.
3. Features: (compared with other inorganic flocculant)
1. High-efficiency inorganic polymeric flocculant.
2. It has better charge neutrality and absorption via bridging mechanism than Polymer Ferric or polysilica flocculant.
3. It is better than Polymer Ferric or polysilica in decolorizing, algae capturing, and COD/BOD reduction.
4. It is better than Polymer Ferric or polyaluminum in treating low-turbidity, low-algae, low-temperature, low-contaminated water.
5. It is non-toxic.
