CPM

Acid-resistant cation membrane

CPM (Product Model) is a breakthrough product
developed by LANRAN Tech to improve upon traditional heterogeneous membrane structures. Utilizing a semi-homogeneous membrane fabrication process and the introduction of a third
monomer, CPM features a unique “sea-island” structure that enhances its microscopic morphology. This innovation results in lower resistance and improved chemical stability, delivering a high-performance ion exchange membrane for a wide range of applications.

Characteristics：

  • Compared to standard semi-homogeneous cation exchange membranes, it performs reliably under more acidic conditions, offering enhanced durability and performance.
  • Higher selectivity permeability enhances current efficiency
  • NaCl solution can be efficiently concentrated to over 15%, while Na₂SO₄ can be concentrated to over 18%, offering a cost-effective solution for high-concentration applications.
  • Its cost-effective pricing makes it highly competitive in the market.

Application field：

  • Widely used across industries for concentration and desalination, its affordable pricing makes it especially ideal for handling high-pollution liquids with frequent replacement cycles.
  • Efficient desalting of materials in industries such as food, pharmaceuticals, chemicals, and biotechnology, as well as zero wastewater discharge in sectors like papermaking, coal chemicals, pesticide manufacturing, dyeing, hydrometallurgy, steel, thermal power generation, petroleum refining, and waste management, promoting sustainability and environmental responsibility.
  • In the food industry, optional control of extractable substances (DOP) ensures safety and quality compliance.
