Membrane And Industrial Circulating Cooling Water Chemicals

With increasingly stringent environmental regulations and escalating water shortages, the water treatment chemical industry has experienced rapid growth, becoming an indispensable core component in membrane systems and industrial circulating cooling water systems. Membrane scale inhibitors, through chromatic aberration and complexation solubilization mechanisms, can reduce the risk of RO membrane scaling by 35%-50% in typical applications under Ca²⁺ concentrations ≤200 mg/L. Combined with intelligent dosing systems (turbidity <1 NTU), the cleaning cycle can be extended from 3 months to 6-9 months. Non-oxidizing bactericides achieve a >99% kill rate against E. coli within 24 hours and are suitable for polyamide membranes sensitive to residual gas (requiring residual gas <0.1 mg/L). Reducing agents are primarily used to eliminate residual gas and protect oxidation-sensitive membrane materials. Flocculants and coagulants remove suspended solids and colloids through charge neutralization and adsorption, reducing membrane fouling load. Industrial circulating cooling water scale inhibitors prevent metal corrosion and scaling by forming a precipitate film, exhibiting significant differences in mechanism of action and dosage compared to membrane scale inhibitors. The synergistic effect of antimicrobial agents and bactericides controls microbial growth, preventing biofilm and under-deposit corrosion. The pre-filming agent forms a film rapidly within 48 hours, reducing the corrosion rate to <0.1 m/year. The rich membrane technology offers a full range of agents covering UF/RO membranes and industrial circulating water systems, including high-efficiency scale inhibitors and biodegradable bactericides. Through intelligent dosing systems linked to real-time water quality monitoring, it helps customers meet their treatment needs for reduced costs and compliance with water quality standards.
