What are some good ways to deal with excessive hardness in circulating water!

Discharge waste water in a timely manner; the hardness level indicates that the concentration ratio of the circulating water has become high. When operating at high concentration ratios for extended periods, heat exchangers are prone to scaling. After discharge, the hardness returned to normal levels; it is necessary to add scale and corrosion inhibitors.

You can take a look at my post; we reduce the hardness of the circulating water by using pre-scaling to remove it. Prevent system scaling at the same time

Discussion on solutions to prevent scaling, rusting, bacterial growth, and algae formation in low-carbon, energy-efficient closed-loop water systems – “Rodsel” closed-loop water optimization equipment. Principle of operation: The control board generates low-voltage, high-frequency electrolytic signals; through the electrodes, low-voltage, high-frequency waves are produced, which are 10,000 times stronger than those generated by magnetic electromagnetic coils. This causes electrical decomposition of the water, separating the active oxygen elements from some of the hydrogen elements. While releasing active oxygen, active hydrogen is retained in the water for an extended period. As a result, the redox potential of the water decreases, transforming the originally large-molecule water into small-molecule reduced water. Through continuous processes of dissolving and removing scale, the hardness of the water is reduced, and impurities such as scale, rust, bacteria, and algae in the pipes are removed, thereby fundamentally improving the quality of the water. “Features of the Rodsel circulating water optimization equipment: Physical scale removal – it uses a purely physical method of treating water with water itself (without any chemical agents); its unique mechanism allows for visible results in scale removal within a short time ； Rust removal without disassembly: Unlike existing rust-removal products, it achieves the removal of rust from equipment and pipe walls without the need for disassembly ； Restore the operational efficiency of the system units ； Bactericidal and algicidal action: In addition to being effective at removing scale, this device also differs from similar ones in that it can improve water quality as well; it achieves bactericidal and algicidal effects by taking advantage of the strong oxidizing power of electrolyzed water ； Without the need to stop production, modify pipelines, or carry out frequent water changes for cleaning, it is possible to maintain stable or decreasing levels of various water quality parameters such as TDS, hardness, chloride ions, pH, calcium and magnesium ions, total phosphorus, and more. For more details, simply search for “Rodsel” on Baidu or Google. Easy to operate: With the Rodsel recirculating water optimization system, it is sufficient to clean the collector 2–3 times per month to achieve the desired results. Even if the system is shut down for a month, there will be no interruptions or alarms in the recirculating water system, **reducing the workload and mental stress on maintenance staff. “Product features of the “Rodessel” circulating water optimization equipment: This equipment utilizes a core technology for reducing water electrolysis, developed through Sino-Japanese collaboration, and is currently unique in China. It offers functions such as emission reduction, energy savings, scale prevention, rust removal, sterilization, and algae control. sunshaofeng@hetangsh.com QQ1178100219
