Industrial Acid Purification Specialty Membrane
What is an Industrial Acid Purification Specialty Membrane?
In many industrial processes such as surface treatment, titanium dioxide production, steel manufacturing, and hydrometallurgy, large volumes of acidic solutions are generated containing valuable metal ions and impurities. Direct discharge or simple treatment of these acids leads to resource loss, environmental burden, and high chemical costs. Therefore, an efficient separation and recovery solution is essential.
The Industrial Acid Purification Specialty Membrane is designed to address this challenge. It is mainly used to separate divalent and multivalent metal ions from acidic solutions, enabling effective acid purification and resource recovery. It can operate in harsh acid environments such as 15% phosphoric acid, 5% nitric acid, and 20% sulfuric acid, maintaining stable separation performance.
By selectively removing metal ions while retaining acid components, the membrane not only improves acid reuse efficiency but also reduces wastewater treatment load. This makes it a necessary technology for modern industries aiming at cost reduction, environmental compliance, and sustainable production.
why choose us
China One-Stop Water Treatment Solution Provider
Founded in 2006, the company has extensive engineering experience and has undertaken provincial-level government projects. It is now focused on the R&D of core membrane technologies, providing customized water treatment solutions for global clients.
From membrane selection to system design and project implementation, we tailor solutions to specific water conditions, delivering reliable performance and professional technical support to address complex water treatment challenges.
In the surface treatment industry, the membrane is applied to purify spent pickling acids by removing accumulated metal ions such as iron and copper, allowing the acid to be reused and reducing chemical consumption and discharge.
In titanium dioxide production, it is used to separate and remove metal impurities from sulfuric acid systems, improving product quality while enabling acid recycling within the process.
In hydrometallurgy, it is widely used to separate multivalent metal ions from acidic leaching solutions, supporting metal recovery while maintaining acid stability for continuous reuse.
Structure of Industrial Acid Purification Specialty Membrane
The structure of the Industrial Acid Purification Specialty Membrane is similar to YIME’s RO membranes, featuring a spiral-wound configuration composed of three main components: membrane sheets, permeate carrier, and feed spacer.
The key difference lies in its post-treatment at the semi-finished stage, where a specialized chemical solution is applied to enhance acid resistance, enabling stable operation in highly acidic environments.
In addition, the membrane is designed with selective separation properties, allowing it to effectively separate divalent and multivalent metal ions from acid solutions, ensuring efficient purification and recovery performance.

Acid Purification Membrane – Frequently Asked Questions
What is the common application of an acid purification membrane?
It is mainly used to purify and recover acid solutions containing divalent or multivalent metal ions, enabling acid reuse. It is widely applied in surface treatment and metallurgy. It can also be implemented in small-scale systems for laboratory testing to verify operational feasibility, providing a reliable basis for large-scale engineering projects.
How to select a suitable acid purification membrane?
Selection depends on your requirements and feed water quality, including acid type, concentration, and metal ion composition. It is suitable for separating metal ions in solutions such as 15% phosphoric acid, 5% nitric acid, and 20% sulfuric acid. Attention should also be given to calcium and magnesium ion concentrations to avoid scaling and ensure stable operation.
What is the service life of the Industrial Acid Purification Specialty Membrane?
The membrane can operate stably for around one year under proper conditions. Due to high working intensity and complex acidic environments, regular cleaning and maintenance are required to ensure consistent performance and extend service life.
How to determine if my water is suitable?
Test key parameters such as suspended solids, oxidants, organics, oil, and hardness. If values meet the required limits and no crystallization risk exists, the system is generally suitable. Pilot testing is recommended for confirmation.
