Product Detail

Leather waste water mainly contains animal oil, collagen, animal fiber, plant fiber, no solid and other organic matter concentration, sulfur, chromium and other harmful ions, is a more difficult to deal with light industrial wastewater, the general use of physical and chemical - biochemical combination process .

The process of sludge dewatering in the post-treatment of leather sewage is to use flocculant polyacrylamide as a sludge dewatering agent. It is recommended to use strong cationic polyacrylamide. Ion degree is generally between 60-70, the molecular weight of about 9 million can be.

Solid polyacrylamide per ton of dry mud consumption is generally 3-8 kg, emulsion polyacrylamide in 6-12 kg. The specific amount of dry mud to be based on the beaker experiment, the machine on the medium-sized experiment or cycle to run the test to determine the muddy of each plant are not the same, different sludge, different agents, different equipment, different management level difference in consumption great.

Product Description: BoYuan water purification laboratory for tanning wastewater in the high protein content, high concentration of organic wastewater, large smell, high color, difficult to deal with the characteristics of multiple experiments to detect and found that it contains a lot of lime, Protein, salt, grease, ammonia nitrogen, sulfide, chromium salt and hair, skin residue, mud and other toxic and hazardous substances

Xinxiang Boyuan Water-purifying Materials Co., Ltd.has many successful cases of tanning wastewater purification.High-level organic wastewater, large odor, high chroma, difficult to deal with the characteristics of many experiments to detect and found that it contains a lot of lime, dyes, protein, salt, salt, water, Class, grease, ammonia nitrogen, sulfide, chromium salt and wool, skin residue, mud and other toxic and hazardous substances. CODCr, BOD5, sulfide, ammonia nitrogen, suspended solids, etc. are very high. There are many tanneries through the conventional aeration aerobic activated sludge process, the process produces a lot of foam, activated sludge will run away with the bubble. The process should be adjusted accordingly. The waste to be used to treat the waste water is ferrous sulfate or basic aluminum chloride, polyacrylamide. In the experiment mainly for waste water in the chromium, ammonia nitrogen, total nitrogen, chloride ions, COD, etc. to remove.

Sludge dewatering experiment Conclusion: Strong cationic polyacrylamide products, such as the source of cationic polyacrylamide 50, are generally used. Molecular weight of about 10 million. Can achieve the best sewage purification effect.

Bo Yuan Water Purification Technology Services Department specifically for your custom leather sewage purification agent cationic polyacrylamide, according to your leather sewage test indicators, targeted formulations, so you in the leather sewage treatment handy.
