Cooling water systems commonly face corrosion, scaling, and microbiological fouling. Corrosion weakens metal surfaces such as pipes and heat exchangers, leading to leaks and equipment damage. Scaling occurs when dissolved minerals like calcium and magnesium precipitate, reducing heat transfer efficiency. Microbiological fouling, caused by bacteria and algae, forms biofilms that block water flow and increase energy consumption. HydroGuard’s chemical programs address these challenges by optimizing water chemistry and providing targeted inhibitors and biocides.

Corrosion can be controlled using phosphate-based or molybdate-based corrosion inhibitors, pH adjustment, and regular system monitoring. HydroGuard’s solutions include on-site analysis, custom inhibitor dosing, and routine inspection, ensuring that metal surfaces remain protected and equipment lifespan is maximized.

Scaling is caused by the precipitation of minerals when water evaporates in the cooling tower. HydroGuard combats this with antiscalants and dispersants that prevent mineral deposition and facilitate the removal of small particulates before they adhere to surfaces. Regular blowdown management and water softening also help maintain proper cycles of concentration.

HydroGuard’s programs prevent corrosion, scaling, and microbial fouling, ensuring efficient heat transfer, lower energy consumption, reduced downtime, and extended equipment life. The solutions are customized to each system based on water analysis, operational requirements, and industry standards.

Cycles of Concentration (COC) represent the ratio of dissolved solids in the circulating cooling water to those in the makeup water. A higher COC means water is being reused more effectively before blowdown, improving water conservation and chemical efficiency. However, if COC exceeds the system’s scaling or corrosion limits, it leads to calcium carbonate deposition, silica scaling, and concentration of corrosive ions (chloride, sulfate).

HydroGuard optimizes COC by:

• Analyzing makeup and circulating water chemistry to determine the safe concentration ratio based on Langelier Saturation Index (LSI) and Ryznar Stability Index (RSI).
• Implementing automated bleed and Hydroguard`s Automation chemical dosing controller allow real time Monitoring and maintaining conductivity within set parameters.
• Adjusting antiscalant and dispersant dosing to safely operate at higher COC, reducing blowdown volume and water cost.
