Polyquaternium-7 Cationic Modifier for Monovalent Selective Separation Membranes and Cationic Flocculant Non-Oxidizing Disinfectant

Polyquaternium-7 as Cationic Modifier for Monovalent Selective Separation Membranes

INCI name : Polyquaternium 7

Appearance :Colorless transparent and viscous liquid

Description:

Quaternary ammonium salt-7 plays a crucial role in industry as a surface modifier for special separation membranes, an efficient cationic flocculant, and a non-oxidizing disinfectant. The following are its detailed applications in various industrial fields.

Applications:

• Special separation membranes (such as electrodialysis membranes):A one-component cation-selective separation layer, used in lithium extraction from salt lakes, seawater desalination, etc.

Its molecules are firmly bound to the membrane surface through sulfonamide bonds, forming a positively charged dense layer that efficiently filters Na⁺, K⁺, and Li⁺ while blocking Ca²⁺ and Mg²⁺, preventing membrane fouling and enhancing purity and efficiency.

• Sludge Dewatering and Wastewater Treatment:Cationic sludge conditioning agent (coagulant), used for deep sludge dewatering.

As a polymer flocculant, it neutralizes charges and promotes adsorption bridging to disrupt the hydrophilic structure of the sludge, releasing internal water, thereby significantly improving the dewatering performance (reducing specific resistance and capillary water absorption time).

• Industrial water treatment system:Non-oxidizing bactericidal and algicidal agent, used for cooling water, swimming pools, etc.

As a strong cationic polymer, it adsorbs and damages the negatively charged cell membranes of bacteria/algae, achieving broad-spectrum sterilization and also having a sludge stripping function.
