Sales Hotline:


Leather industry is an industry which easily produces toxic and hazardous substances, especially Cr and other hazardous substances. Leather is denatured and nonperishable animal skin produced through dehairing, tanning, physical and chemical processing procedures. Leather is composed of natural protein fibers tightly woven in a three-dimensional space. Its surface is with a special particle surface layer featured in natural grain line, gloss and comfortable hand feel. Leather is an indispensable item in modern social life. However, leather industry also produces a large amount of waste water and sludge, which requires deep treatment. Leather sewage treatment produces a large amount of leather sludge. Materials used in leather processing process are mostly additives, lime, sodium sulfide, ammonium salts, vegetable tanning agents, acids, alkalis, proteases, chrome tanning agents, neutralizing agents and etc. Therefore, COD content is large, which seriously affects the environment. According to relevant national regulations, leather sludge needs to be uniformly recycled by qualified companies. For large-scale leather companies, expense caused by leather sludge treatment is a heavy burden. TAEDA recommends leather sludge disposal units use leather sludge dryer to reduce sludge quantity, moisture content and weight so that to control recycling costs.
At present, main treatment method is to remove toxic and harmful ingredients after drying and then use them as resources. TAEDA can design drying plan according to customers’ resource-recycling technology route. In terms of leather sludge drying and quantity reduction, Zonelion Taeda recommends following drying technologies and equipment that have been optimized for many years and have enjoyed great popularity: low temperature belt drying system, low-temperature exhaust heat drum drying system, steam rotary drum drying system, drum sludge drying system and air swept rotary wing drying system.
