Guangzhou Shincci Energy Equipment Co., Ltd.
The low Temperature Sludge Dryer made by Shincci can directly reduce the moisture of sludge from 83% to 10%-30% as per specific requirement, with volume reduction by 67%, weight reduction by 80% and sterilization by 90%. It is energy-efficient and eco-fri
The sludge obtained from the treatment of tannery wastewater, whether it is a biochemical sludge with low chromium content, or a high-concentration chromium sludge obtained by alkali precipitation, can be dried and reduced to help you treat leather sludge in the most economical and environmentally friendly way. electroplating sludge is quite complex, mainly containing chromium, iron, nickel, copper, zinc and other heavy metal compounds and soluble salts.
Electroplating sludge mainly comes from the solid waste generated by various electroplating waste liquids and electrolytic bath liquids of industrial electroplating plants after liquid phase chemical treatment. Due to the different production processes and treatment processes of electroplating manufacturers, the chemical composition of electroplating sludge is quite complex, mainly containing chromium, iron, nickel, copper, zinc and other heavy metal compounds and soluble salts.
The main process units include: industrial park sewage treatment, pending sludge drying reduction, dry sludge Utilization of blending by thermal power plant, industrial park production heat supply, dryer heat source recycle and reuse as well as other process, which formed an industrial chain that has the characteristics of circular economy and can be replicated and promoted, known as Sludge Treatment Demonstration Base in FOSHAN city. This project was rated as "Excellent Case of Chinese Sludge Treatment and...

Overview of leather sludge: There are two types of leather sludge, one is sludge such as leather shavings and minced meat, which can be handed over to the gelatin factory for disposal and must not enter the food chain. The other is the sludge obtained after treatment of tannery wastewater. Biochemical sludge with low chromium content and high-concentration chromium sludge obtained by alkaline precipitation.
Sludge Characteristics: Textile printing and dyeing sludge in Xinlong WWTP, which contains a lot of textile fiber fluff, has been tested that the volatile content of textile printing and dyeing sludge is relatively high (about 40%) when the moisture content is changed from 40% to 30%. To prevent explosions during the drying process, a low-temperature dehumidification drying technology with a drying temperature not higher than 90°C is adopted.
