The Key Role of Industrial Filter Cloth: The Dual Application of Drum Vacuum Filters in Wastewater Treatment and Lithium Extraction
In “ Double Carbon ” Against the backdrop of the strategic promotion of "Double Carbon" and the rapid development of the new energy industry, how to efficiently carry out wastewater resource treatment and achieve high-value extraction of lithium resources has become a core issue that balances industrial manufacturing and environmental governance. Drum Vacuum Filter with its continuous and efficient separation capabilities, plays an irreplaceable role in both fields. As one of the core components of this equipment, the quality of the industrial filter cloth directly determines the efficiency and quality of the entire separation process. 。
Drum Vacuum Filter: A Bridge Connecting Environmental Protection and Resource Extraction
A drum vacuum filter is a typical continuous operation equipment. The filter drum is semi-immersed in the slurry. As the drum rotates, the filter cloth uses vacuum to achieve solid-liquid separation, and then the filter cake is removed by backblowing or a scraper. It is widely used in metallurgy, chemical industry, environmental protection, and new materials industries, especially suitable for the following two scenarios:
1. Industrial Wastewater Treatment
In wastewater treatment in the metallurgical, electroplating, and chemical industries, drum filters can be used for:
- Removing suspended solids and heavy metals;
- Recovering valuable metal particles;
- Concentrating sludge and dewatering to reduce volume;
- Achieving pretreatment or compliance discharge of water;
2. Lithium Resource Extraction
In processes such as spodumene roasting and salt lake brine lithium extraction, drum filters are used for:
- Filtering acid-leached slurry;
- Separating precipitated lithium salt mother liquor;
- Washing lithium-containing filter cakes to reduce product loss;
- Dewatering intermediate product solid-liquid to improve process closed-loop efficiency;
In these applications, the advantages of drum filters lie in their large processing capacity, stable operation, and continuous operation, especially suitable for process sections with moderate slurry solid content and high requirements for filtrate clarity.
Filter Cloth: The “ Final Interface that Determines Success ”
Whether it is fine suspended solids in wastewater or solid residue in the lithium extraction process, efficient capture and rapid dehydration can be achieved depends on whether the performance of the filter cloth precisely matches the target operating conditions.
