JSYA-PQ Polyquaternary Ammonium Biocide is a cationic polymeric quaternary ammonium compound (polyquat) designed for microbial control in circulating water and recirculating cooling water systems. As a non-oxidizing biocide, it carries positively charged quaternary ammonium groups along the polymer chain that strongly adsorb onto negatively charged bacterial cell walls, algae cells and fungal membranes. This adsorption changes membrane permeability, causes intracellular leakage and suppresses re

Product Detail

Product Details

JSYA-PQ appears as a light yellow to amber water-soluble liquid polymer. It mixes freely with water and can be dosed directly into cooling tower basins, circulating water lines or process water systems through continuous feeding or periodic shock dosing. The polymeric backbone provides good penetration into accumulated slime and a moderate stripping effect on attached biofilm. It is typically used as part of a rotating biocide program alongside oxidizing agents such as chlorine or bromine, and may be combined with scale inhibitors and corrosion inhibitors under a compatible dosing sequence. Because it is cationic, dosing should be separated from anionic deposit control polymers to avoid electrostatic complexing and precipitation.

Main advantages:

Dual function: sterilization and algae control for circulating water
Broad-spectrum activity against bacteria, algae, fungi and slime organisms
Non-oxidizing chemistry, suitable for rotation with oxidizing biocides
Cationic polymer structure with strong cell-surface adsorption
Good penetration and biofilm stripping performance
Fully water-soluble, low foam and easy to dose
Suitable for continuous feed and periodic shock treatment
REACH / TSCA compliant for industrial water treatment export

Typical applications:

Open recirculating cooling water systems and cooling towers
Industrial circulating water sterilization and algae suppression
Heat exchanger and process water circuit microbial control
Slime and biofilm removal in water treatment systems
Complementary biocide in scale and corrosion inhibitor programs
General industrial fresh water microbial control

JSYA-PQ polyquaternary ammonium biocide provides a reliable cationic polymer option for circulating water treatment. It helps operators keep bacterial counts and algae growth under control, reduce slime fouling on heat exchange equipment and support stable, efficient operation of industrial water systems.
