NEWS AND EVENTS

Industrial circulating water filtration is designed to help industries maintain clean and consistent water quality in circulating cooling water and process systems. The filtration system removes suspended solids, rust and other impurities found in the water as it recirculates through the system. By eliminating fouling, scaling and corrosion, circulating water filtration can increase heat transfer capabilities, prevent equipment fouling on pumps and heat exchangers, and decrease maintenance and operating costs. Self-cleaning filters, sand filters, and side-stream filtration systems are just a few examples of popular circulating water filtration technology. These systems are used in a variety of applications including HVAC, cooling towers, power plants and manufacturing facilities. Implementing proper filtration into a circulating water system can improve process reliability and increase equipment longevity.

Water treatment is essential for HVAC systems to ensure efficient, reliable, and safe operation. Untreated water can cause scale buildup, corrosion, and biological growth, all of which reduce heat transfer efficiency, increase energy consumption, and damage equipment. By controlling water quality through proper treatment, systems can maintain optimal performance, lower operating costs, and extend equipment lifespan. Additionally, water treatment helps meet regulatory requirements and prevents health risks associated with microbial contamination. Overall, it is a critical component in maximizing HVAC system efficiency and long-term stability.
 

Circulating water system treatment is a process for keeping water circulating through a HVAC system or industrial cooling system in a pure and usable condition. Water treatment inhibits scaling, corrosion, biological growth, and fouling which can diminish efficiency, capacity and damage pumps, cooling towers and associated equipment.
Treatment methods include chemical injection, filtration, water softening, blowdown optimization, and system monitoring. Water treatment improves heat transfer efficiencies, cuts energy consumption and operating costs and increases the life expectancy of equipment.
Well treated circulating water systems will operate reliably and have long equipment lives.

This guide explains how to effectively remove and prevent corrosion in pipelines used across industrial, municipal, and commercial systems. It outlines the main types of corrosion—electrochemical, chemical, microbial, and scale-induced—along with their causes and impact on pipeline performance. The article details both mechanical removal methods, such as sandblasting, high-pressure water jetting, and rubber ball cleaning, and chemical approaches including acid pickling, passivation, and chelation. It also emphasizes the importance of post-cleaning strategies like electronic descaling, precise chemical dosing, and regular inspection to ensure long-term pipeline integrity, improved efficiency, and reduced maintenance costs.
 

HVAC water treatment is critical for ensuring system efficiency, reliability, and safety by controlling corrosion, scale, and microbiological growth. Untreated water can damage equipment, reduce heat transfer, increase energy costs, and create health risks such as Legionella contamination. Effective treatment combines chemical methods—like corrosion inhibitors, scale inhibitors, biocides, and pH adjustment—with non-chemical solutions such as filtration and electromagnetic treatment. Closed-loop systems focus on corrosion and microbial control, while open-loop systems require stronger scale management. Proper water treatment can reduce energy consumption by 15–30%, extend equipment lifespan, improve indoor air quality, and ensure regulatory compliance, making it a cost-effective and sustainable investment for HVAC systems.
 

Maintaining stable water quality is essential for ensuring efficient system operation and extending equipment lifespan. Key parameters such as pH, hardness, dissolved oxygen, total dissolved solids (TDS), chlorine, turbidity, and alkalinity all play a role in influencing scaling, corrosion, and fouling. Rather than focusing on a single factor, effective water management requires continuous monitoring and balanced control of these indicators. By keeping these parameters within reasonable ranges, industrial and HVAC systems can achieve more reliable performance, lower maintenance costs, and longer service life.
