Homogeneous Cation Exchange Membrane (HP-CM Series)

High Selectivity Cation Membrane for Industrial Desalination, Concentration & Valuable Metal Recovery

HP-CM homogeneous cation exchange membranes feature uniformly grafted sulfonic acid cation exchange groups. The homogeneous structure delivers high cation retention rate, low resistance and robust mechanical strength. Widely used in electrodialysis desalination, lithium extraction from salt lakes, heavy metal recovery, acid & alkali concentration and zero liquid discharge wastewater systems.

Common Industry Challenges

Low Recovery Rate of Valuable Metals

Poor cation selectivity causes severe loss of lithium, nickel, copper and zinc, wasting high-value raw materials and cutting project profit.

Tech: Cation permselectivity ≥98%, metal recovery rate 95%-98% for salt lake and metallurgy projects.

Irreversible Fouling from Hard Water

Divalent metal ions adhere to membrane surface, leading to permanent flux drop and premature membrane scrapping.

Tech: HP-CM-200 anti-scaling formula slows irreversible flux decline under hard water conditions.

Short Service Life Under Strong Acid & Alkali

Ordinary cation membranes degrade rapidly in acid/alkali recycling and high-corrosion production lines, raising frequent replacement costs.

Tech: HP-CM-300 reinforced substrate, full pH 0–14 corrosion resistance for harsh corrosive working conditions.

Membrane Breakage During Transit & Installation

Low mechanical strength leads to breakage during sea freight vibration and field assembly, causing cargo rejection and project delay.

Tech: Composite fiber reinforced frame, burst strength ≥1.0MPa to avoid breakage and returned goods.

Types of Homogeneous Cation Exchange Membranes

The Advantage Of Homogeneous Ion Exchange Membrane

Due to the uniform distribution and high content of ion exchange groups, the homogeneous ion exchange membrane has a high ion exchange capacity, which can effectively carry out the exchange reaction with the ions in the solution, and can be used for efficient ion separation and enrichment.

Good selectivity:

Good selectivity for different ions, based on the differences in charge, size and hydration radius of ions, it can preferentially select specific ions to pass through the membrane, and realize accurate ion separation in mixed ion system.

Low resistance:

Uniform structure, low resistance to ion transport within the membrane, low membrane resistance, which can reduce power consumption and improve energy efficiency in electrochemical processes such as electrodialysis.

Good chemical stability:

Stable in a wide pH range and a variety of chemical environments, not easy to chemical degradation or structural damage, resistant to strong acids, strong bases and a variety of organic solvents, suitable for dealing with a variety of complex chemical systems.
