Circulating Water Treatment Chemicals

The cooling water system is an essential component of industrial and commercial facilities, widely used in cooling, heating, and production processes. As the system operates over time, the water quality deteriorates, which can lead to scaling, corrosion, microbial growth, and other issues, severely threatening the efficiency and lifespan of the equipment. By using professional cooling water treatment chemicals, it is possible to effectively control deposition, corrosion, and biological contamination within the system, improve energy efficiency, extend equipment lifespan, and reduce overall operation and maintenance costs.

What Success Stories Can We Share?

Discover how our products are applied in real-world scenarios through our case studies.

Case 1: Cooling Circulating Water System Scale and Corrosion Control Optimization Project for a Power Plant

Project Background

A large power company’s cooling circulating water system faced severe calcium carbonate scaling and reduced heat exchange efficiency over time. Additionally, localized corrosion was detected in the system's pipes, affecting equipment safety and operation.

Solution

Our technical team conducted a thorough water quality analysis and identified high hardness and alkalinity levels, which led to strong scaling tendencies, as well as an excessively high concentration factor.

To address these issues, we recommended using our proprietary organic phosphonate-based scale and corrosion inhibitor, integrated with an intelligent dosing control system for precise chemical management.

Implementation Results

Scale thickness on pipes and heat exchangers reduced by over 85%.
Heat exchange efficiency improved by 15%, with energy consumption decreasing by approximately 8%.
Corrosion rate dropped from 0.18 mm/a to 0.05 mm/a, meeting national standards.
The system operated continuously and stably for 12 months without the need for major cleaning.

Case 2: Biological Contamination Control Project for Cooling Towers in a Commercial Complex

Project Background

A large commercial complex experienced frequent microbial contamination in its cooling tower system during summer, leading to biofilm accumulation, reduced cooling efficiency, and odor complaints, which negatively impacted customer experience.

Solution

Based on on-site testing, we found that microbial counts exceeded the limits, and conventional chlorine-based disinfection was insufficient.

We implemented a comprehensive control strategy:

Combined non-oxidizing biocides (Isothiazolinone series) with low-dose oxidizing biocides.
Weekly water quality testing to adjust chemical dosing.
Use of highly efficient dispersants to disrupt biofilm structure and improve bactericidal efficacy.

Implementation Results

Microbial count decreased to below national standards within 2 weeks.
No visible biofilm in the cooling tower, with cooling efficiency improving by 12%.
Significant reduction in odor complaints and a noticeable increase in customer satisfaction.
Maintenance workload decreased by more than 30%.

Case 3: High-Salinity Water Treatment Project for a Steel Mill Cooling Circulating Water System

Project Background

A steel mill’s cooling circulating water system used high-concentration water to meet process requirements, resulting in very high salinity levels. The system frequently faced scaling and corrosion issues, with traditional chemicals proving ineffective and maintenance costs soaring.

Solution

For the high-salinity, high-hardness water quality, we recommended:

Special high-salt tolerance scale inhibitors specifically designed to suppress inorganic scale formation in high ion-strength environments.
Organic corrosion inhibitors to stabilize the film-forming process in high-salinity conditions, protecting metal surfaces.
Lowering the concentration factor and using dispersants to maintain the stability of suspended solids.

Implementation Results

Scaling rate reduced by 70%, with cleaning intervals extended from 3 months to 9 months.
Corrosion rate was controlled to industry best standards (less than 0.05 mm/a).
The overall system efficiency increased by 9%, saving over ¥500,000 per year in operational costs.

Frequently Asked Questions (FAQ)

What chemicals should be used during the initial startup of a cooling water system?

It is recommended to use a combination of corrosion inhibitors and biocides to quickly stabilize water quality and protect equipment surfaces.

Can cooling water treatment chemicals be used with automatic dosing systems?

Absolutely, all of our chemicals are fully compatible with automated dosing management systems.

How should the chemical dosing amount be adjusted when water quality fluctuates?

The dosing amount should be dynamically adjusted based on water quality data and changes in system load.

How is the dosage of scale inhibitors determined for a cooling water system?

The dosage of scale inhibitors should be evaluated based on system water quality, concentration ratio, flow rate, and scale type. We recommend detailed water quality analysis, including concentrations of calcium ions, bicarbonates, and sulfates.

How do corrosion inhibitors ensure compatibility with different metal materials and maintain consistent effectiveness?

The choice of corrosion inhibitors should consider the types of metals in the system, such as carbon steel, stainless steel, and copper alloys. We use multi-component formulations to generate effective protective films for each metal type, preventing selective corrosion. Molecular design enhances compatibility with different metals to ensure comprehensive protection. For special conditions, on-site testing is recommended to optimize the chemical formulation.
