Wastewater from paper mills

 ‌                                                                             Paper mill wastewater treatment case

PAC gel breaking and decolorization - clear in 15 minutes

Adding highly alkaline polyaluminium chloride (PAC):

✅ Disintegrate colloids:  Multi-nuclear complexes neutralize the negative charge of lignin and break the "colloid protective layer"

✅ Deep decolorization: Exclusive formula adsorbs dye molecules, chromaticity removal rate> 85%

✅ Widely suitable pH: resistant to acid and alkali shock (pH 4-10), eliminating the cost of regulators

Case of a packaging paper mill: After PAC was added, the chromaticity of the black liquor dropped from 500 times to 50 times, and the flocs increased by 3 times.

PAM net captures fibers - sedimentation rate doubles

Precisely match anionic polyacrylamide (APAM):

    Ultra-long molecular chain: bridges and captures fine fibers, and the density of flocs is increased by 60%

    Anti-shear formula: high-speed stirring does not break flocs, and the sedimentation tank load is halved

    Low-temperature efficiency enhancement: the sedimentation rate at 5℃ is still 1.2m/h

    Measurement of cultural paper production line: fiber removal rate is 98.7%, and the clean water reuse rate is increased to 80%

 Sludge becomes "dry cake" - the disposal cost is reduced by 65%

Use cationic polyacrylamide (CPAM) to dehydrate:

 Charge neutralization: cationic groups break the viscosity of sludge and release bound water

 Sludge moisture content ≤75%: after plate and frame filtration, the sludge is in blocks without dripping, and the volume is reduced to 1/3

 Save 40% of the reagent cost per ton of sludge: the dosage of high-activity CPAM is only 0.3kg/ton of sludge

Why do paper mills choose us?

Exclusive advantages:

✅ Fiber recovery system: PAM flocculated pulp fibers can be reused, saving more than 7000USD  in raw material costs annually。

✅ Anti-interference formula: Tolerant to high salt content in pulping wastewater (such as kraft pulping)

✅ Intelligent dosing system: Linked with influent COD to automatically adjust PAC/PAM dosage to eliminate waste
