In the process of leather production, a large amount of wastewater will be generated after chromium tanning and retanning processes using chromium tanning agents. This waste water will form sludge and residue during the treatment process, that is, leather sludge. Leather sludge not only contains a lot of water, but also often contains toxic and harmful substances such as heavy metal chromium, which brings great challenges to environmental treatment. In order to effectively deal with this challenge, sludge enhancer, as a highly efficient chemical agent, is gradually becoming a useful assistant in the treatment of leather sludge.

Leather sludge treatment problems

Leather sludge has the characteristics of high moisture content, high viscosity, difficult to dehydrate, etc., and it often faces many problems in the treatment process. Traditional treatment methods are often ineffective and difficult to meet the requirements of environmental protection. At the same time, because the leather sludge contains harmful substances such as heavy metal chromium, improper treatment may also cause secondary pollution to the environment.

Application advantages of sludge synergists

Sludge enhancer is a chemical agent specially designed to improve sludge dewatering performance, which shows unique advantages in the treatment of leather sludge:

Efficient dehydration: The sludge synergist can destroy the colloidal structure in the leather sludge, reduce the viscosity and surface load of the sludge, and make the sludge particles easier to separate and dehydrate. This helps to significantly reduce the moisture content of the leather sludge and reduce the volume and weight of the sludge.

Removal of heavy metals: In the process of treating leather sludge, the sludge synergist can also effectively remove or immobilize harmful substances such as heavy metal chromium, reduce the toxicity of the sludge and reduce the impact on the environment.

Improve treatment efficiency: After the use of sludge enhancer, the dewatering efficiency of leather sludge is significantly improved, and the dewatering time is shortened, thus reducing the treatment cost. At the same time, the dehydrated sludge is easier to transport, store and dispose of later.

Environmental protection and economy: The sludge enhancer does not need to add auxiliary agents such as lime during use, avoiding problems such as equipment corrosion and clogging of filter cloth. At the same time, the treatment effect is stable and reliable, meets the requirements of environmental protection, and brings significant economic and environmental benefits for the tannery.

Application of sludge enhancer

A tannery introduced sludge enhancer to dehydrate the leather sludge when treating it. After a period of trial, the plant found that the dehydration efficiency of the sludge was significantly improved, and the water content of the dehydrated sludge was reduced from more than 80% to less than 60%. This not only reduces the volume and weight of the sludge, reduces the transportation and disposal costs, but also effectively removes harmful substances such as heavy metal chromium in the sludge and protects the environment.

In the face of the treatment problems of leather sludge, sludge enhancer has become the effective assistant for the treatment of leather sludge with its advantages of efficient dehydration, removal of heavy metals, improvement of treatment efficiency and environmental protection and economy. With the increasingly stringent environmental requirements and the continuous development of the leather industry, sludge synergists will play a more important role in the field of leather sludge treatment. For tanneries, the selection of sludge enhancers for sludge treatment not only helps to enhance the environmental image of enterprises, but also reduces treatment costs and achieves sustainable development.
