1, clarification and purification;

2. Settlement promotion;

3. Promote filtration;

4. Thickening and other functions.

It can completely meet the requirements of waste liquid treatment, sludge concentration and dehydration, mineral processing, coal washing, paper making and other fields.

Treatment scheme of coal washing wastewater:

Coal preparation plants generally adopt the treatment process of "cyclone-thickener-filter press (slime sedimentation tank)". Generally speaking, it is a polymer flocculant (polyacrylamide) purchased from the machine. Polymer flocculant contacts with coal slime particles or colloid, neutralizes the electrical property of coal slime surface, reduces the surface energy, and makes coal slime particles coagulate and precipitate. The molecular weight of polyacrylamide is generally between one million, and flocculants with different molecular weights should be selected for slime water with different particle sizes. Polyacrylamide can be divided into anionic polyacrylamide, cationic polyacrylamide and nonionic polyacrylamide. When using polyacrylamide for water treatment, it is necessary to ensure that the model is consistent with the pH value of coal slurry. Anionic polyacrylamide is suitable for alkaline coal slime, cationic polyacrylamide is suitable for acidic coal slime, and the flocculation and sedimentation effect of coal slime is better when anionic polyacrylamide and cationic polyacrylamide are mixed.

Features:

1 has good water solubility and can be completely dissolved in cold water.

2. Good flocculation effect can be obtained by adding a small amount of this anionic polyacrylamide product. Generally, it only needs to add 0.01~10ppm (0.01~10g/m3) to give full play to its functions.

3. Use anionic polyacrylamide products and inorganic flocculants (polymeric ferric sulfate, polymeric aluminum chloride, iron salt, etc.). ) at the same time can show greater effect.
