Pulp & Dyeing
When employing bipolar membrane electrodialysis (BMED) technology to treat wastewater from the paper and printing industry, several benefits are realized:
Environmental protection: Efficiently removes salts and pollutants, preserving water resources and ecological balance.
Resource recovery: Separates salts for production of acids and bases, facilitating recycling and reducing costs.
Cost reduction: Integrates produced acids and bases directly into processes, minimizing procurement expenses and legal liabilities.
Corporate image: Demonstrates eco-friendly practices, enhancing brand reputation and sustainability efforts.
Regulatory compliance: Ensures adherence to environmental regulations, avoiding penalties and legal issues
