Embrace Ultimate Application Challenges of Filtration, Separation, and Purification Technology
Electrolytic Copper Foil Filtration Applications
Copper is widely used in lithium-ion batteries and printed circuit boards for its conductive properties. As copper is developing into thinner, high ductility foils for use in the electronics industry today, electrolyte purification is increasingly important to improve the quality of copper foil. Feature-Tec has various solutions to reduce operational complexity, element change-out frequency and air pollution reduction.
Copper Contaminants
| Contaminants | Sources | Impact |
|---|---|---|
|
Particulates Oil, hydrocarbons, etc |
Feed & pipeline Corrosion contamination |
Pitting, holes in copper foil |
Time Consuming & Complex Maintenance
Strainers, cartridge & bag filters are commonly used today for electrolyte filtration processes. As manual washing and change-out is required, the complicated process exposes technicians to harmful particles. The problem can be solved by using larger housings with more elements, increasing the process working time to reduce duration of contact with harmful materials.
Feature-Tec Filtration System
Fully Automatic, Simple Maintenance, High Precision
Feature-Tec multi-stage filtration system purifies electrolytes by installing filters before and after heat exchangers. The SelfClear automatic filtration system provides efficient, fully sealed performance compared to manual change-out filter housings, effectively controlling the purity of electrolytes.
Filter Applications
Different filters are used at each stage to remove contaminants, ensuring purity of the end product.

Feature-Tec provides filtration solutions according to our clients’ work process and required filtration precision. The micron rating of filters can be adjusted, while oil absorption pillows can be added for increased oil absorption from the process.
Surface Treatment
Bath liquids used for treating copper foils should be filtered to remove contaminants, ensuring high product quality.
As treatment of copper foils requires many complex steps involving circulating washing liquids, the Jumbo filter system extends the service life of the fluids by filtering the fluids before reuse
