Technical Definition Homogeneous diffusion dialysis membranes are electricity-free separation membranes based on concentration difference principles, designed to recover inorganic waste acids while retaining metal ions, serving as core components for industrial waste acid resource utilization . Main Categories To meet diverse industry needs, our product line includes customizable solutions:

- Regular Acid Recovery Membrane (DD): Standard series for hydrochloric/sulfuric acid recovery, featuring high acid permeability

- Phosphoric Acid Recovery Membrane (PD): The only domestic membrane for phosphoric acid recycling, filling market gaps

- Monovalent Acid Recovery Membrane (MD): Suitable for complex mixed acid scenarios with precise ion separation

Design Concept Our products adhere to the core design concept of high recovery efficiency, low energy consumption, long service life, and adaptability to harsh working conditions, ensuring stable, low-maintenance, cost-effective solutions for industrial scenarios .

Technical Principles

The core working principle relies on concentration difference: acid ions permeate through the membrane from the waste acid side to the freshwater side, while metal ions are retained in the original waste liquid, requiring no external power supply .

Core Architecture & Innovative Design

- Homogeneous Membrane Matrix: Dense uniform structure enhances ion selectivity and membrane lifespan, reducing performance decay

- Ion Exchange Groups: Precisely regulated to improve acid permeability while blocking metal ions, ensuring high separation efficiency Comparison with Traditional Schemes Unlike traditional neutralization methods that produce large amounts of waste salt and incur high costs, our membranes achieve 2 times higher treatment efficiency than domestic similar products, reducing fresh acid consumption by 51% and alkali costs by 62% annually .

Technical Parameters & Specifications

All parameters are tested strictly per ISO standards, with clear test conditions and tolerance control. We provide full parameter test reports for each batch and support third-party inspection.
