Paper wastewater mainly comes from pulping and papermaking processes in paper industry. Pulping is the separation of fibers from plant raw materials, making pulp, and then bleaching; Paper making is the dilution, forming, pressing, drying of pulp into paper.
Both processes discharge a large amount of wastewater. Wastewater from pulping is the most polluted. Wastewater discharged during pulp washing is black-brown, which is called black water. The concentration of pollutants in black water is very high. BOD is as high as 5-40g/L. It contains a lot of fibers, inorganic salts and pigments. The waste water from bleaching process also contains a lot of acid-base substances. The waste water discharged from paper machine is called white water, which contains a lot of fibers and fillers and adhesives added in the production process.
Paper industry wastewater treatment should focus on improving the recycling water rate, reducing water consumption and wastewater discharge. Meanwhile, various reliable, economical and effective treatment methods should be actively explored to make full use of the useful resources in wastewater. For example, flotation method can recover fibrous solid substances in white water, the recovery rate can reach 95%, clarified water can be reused; combustion method can recover sodium hydroxide, sodium sulfide, sodium sulfate and other sodium salts combined with organic matter in black water.
The application of polyacrylamide flocculant in papermaking wastewater treatment and fiber recovery is conducive to meeting the discharge standards. Anionic flocculant for air flotation, settling and cationic flocculant for mud compaction.
Usage:
When using this PAM concentration should be controlled in 0.1-0.2%,do not use the equipment and matching dissolved dosing system,shell be equipped with dilution tank. The use of screw pump to add,the amount of adjustment according to the actual situation.
Polyacrylamide is used widely , should be selected according to different industry .
Packaging:
25KG Kraft paper packing bag,or as orders.
Dry powder Polyacrylamide long exposure will absorb moisture,should be stored in a cool ventliated dry place,the effctive storage period 24 months
