Metal Recovery Membrane
What is a Metal Recovery Membrane?
An Overview of YIME Metal Ion Recovery Membranes
Metal Recovery Membrane
Metal ion recovery membranes are a type of specialty membrane designed specifically for the separation and recovery of metal ions. Depending on different application requirements, they can be categorized into copper ion concentration membranes, nickel ion concentration membranes, gold ion concentration membranes, and silver ion concentration membranes.
The common feature of these membranes is their ability to efficiently separate and concentrate metal ions in solution while also partially removing dissolved salts. They are widely used in industries such as electroplating wastewater treatment and hydrometallurgy.
Working principle
The basic principle of metal ion recovery membranes is selective permeation, which enables the separation of different components in a mixed solution through molecular and ionic screening. These membranes can selectively separate monovalent or divalent metal ions to obtain the desired enriched solution.
In a complete metal recovery process, a single membrane is usually not sufficient. Instead, multiple membrane systems are required to work in combination. Through step-by-step concentration, metal ions are enriched to a level suitable for recovery and extraction by electrolysis equipment.

Is this product reliable?
Yes, it is reliable. The product has been operating stably for more than three years in multiple real-world projects and has applied for related patents. In addition, an experienced engineering team provides full-process project guidance to ensure long-term stable operation and efficient recovery performance.
Is this project limited by region?
There are no regional limitations. However, the prerequisite for metal recovery is that the feed water must contain recoverable target metal elements. The specific water quality needs to be professionally analyzed to ensure it meets the inlet requirements of the metal recovery membrane system.
Can the equipment and membranes be purchased together?
Yes. The equipment can be fully assembled and tested in China before shipment, but membranes will not be pre-installed. The storage tank must be prepared by the buyer. If on-site installation is required, an additional fee will be charged.
What is the service life of the metal recovery membrane?
Typically one year. The metal recovery membrane needs to be replaced annually and maintained with regular chemical cleaning cycles. Due to the complex feed water quality and high precision requirements, long-term use without replacement will reduce metal recovery efficiency and system stability.
How to select a metal recovery membrane?
Selection is generally based on feed water quality to determine the required number of membrane stages. If the metal ion concentration is high, a single-stage system can be used. If the concentration is low (e.g., in electroplating wastewater), a multi-stage system is required to gradually concentrate the solution and improve recovery efficiency.

product key technologies
Nano-Treated Membrane Sheet Enhancemen
During membrane sheet production, a nano-scale treatment is applied to enhance the mechanical strength and overall durability of the membrane material. This process improves the internal structure, increasing resistance to pressure and long-term operation. At the same time, the winding process is carefully controlled to ensure uniform layer distribution and stable structural integrity of the final membrane element.
Pressurized Chemical Reprocessing & Protection
After the semi-finished spiral-wound element is formed, integrity testing is carried out to ensure reliable sealing performance and eliminate potential defects. According to the type of metal recovery membrane required, the element then undergoes a secondary treatment using a specialized pressurized chemical dosing system, which further optimizes its performance and stability. Finally, the element is reinforced with fiberglass wrapping to provide additional protection, improve durability, and extend service life during operation.
Metal Recovery Membrane Product Advantages
The metal recovery membrane features high selective separation capability, enabling efficient enrichment and extraction of target metal ions while maintaining stable performance and high recovery efficiency in complex wastewater systems.
The system supports continuous online operation, allowing simultaneous wastewater treatment and metal recovery, reducing batch processing steps and improving overall process efficiency and production continuity.
By integrating metal resource recovery with water recycling, it effectively reduces wastewater treatment costs and raw material consumption, enhancing overall economic benefits and resource utilization.
After metal ions are recovered from metal-containing wastewater, the treated water can be directly discharged up to standard, or further directed to an RO membrane system for advanced treatment and reuse, maximizing water resource utilization.
