Circulating Cooling Water Monitoring & Corrosion Control System | GAIMC

The Critical Role of Water Quality in Circulating Cooling Systems

The circulating cooling water system is a water supply system that is recycled after heat exchange in a heat exchanger and cooling in a cooling tower. As a core technology for industrial water conservation, it can inhibit scaling and corrosion, extend equipment life, and improve circulation efficiency through water quality monitoring and chemical regulation. It can achieve efficient circulation of water resources, reduce pollution emissions, promote closed-loop management of industrial water use and green transformation of high-water-consuming industries, and help save water, reduce emissions and achieve sustainable development.

Essential Monitoring Parameters for System Protection

Continuous monitoring of these key parameters is fundamental to preventing scale, corrosion, and microbial growth in your cooling system.

1. pH Value

An indicator that reflects the pH value in water. It dynamically adjusts the acid-base balance and combines with corrosion inhibitors to synergistically control corrosion and scaling.

2. Conductivity

It reflects the ion concentration in the water and controls the concentration multiple by monitoring the conductivity to avoid scaling or corrosion caused by excessive salt.

3. Suspended Solids Concentration

Monitoring suspended solids can prevent pipe blockage, corrosion and microbial growth, ensure system efficiency, extend equipment life, and reduce energy consumption and maintenance costs.

4. Turbidity

Monitoring turbidity can prevent the deposition of suspended matter, avoid corrosion and reduced heat transfer efficiency, ensure stable system operation and extend equipment life.

5. Residual Chlorine

It refers to the residual amount of free chlorine in water. When the residual chlorine concentration is too low, the bactericidal effect is insufficient; if it is too high, it may aggravate the corrosion of metal equipment.

6. Hardness

By monitoring the hardness, the softening process can be adjusted in time to avoid the formation of scale layers caused by the combination of calcium and magnesium ions with acid radicals, which leads to reduced membrane flux and thus prolongs the membrane life.

Intelligent Cooling Water Management & Optimization System

GAIMC's integrated solution utilizes online water quality analyzers to continuously monitor key parameters such as pH, conductivity, and residual chlorine throughout the entire circulating cooling water system. Real-time data is reliably transmitted via RS485 to a central platform, where advanced big data models and AI algorithms perform multi-dimensional analysis. This enables intelligent early warnings, automated chemical feed control, and process optimization. The result is sustained water quality compliance, significantly extended equipment lifespan, reduced energy consumption, and a comprehensive, safe, and economical lifecycle management solution for your industrial cooling operations.

Additional Critical Parameters for Pretreatment & Membrane Protection

For systems incorporating reverse osmosis or ion exchange, these additional parameters are vital for protecting sensitive membrane and resin components.
