As an indicator of the acidity and alkalinity of a solution, pH value has a multi-faceted and important impact on industrial water, which is mainly reflected in the following aspects: Impact on equipment Corrosion and scaling Corrosion: When the pH value is too low, the water is acidic and will corrode metal pipes and equipment. For example, acidic water will react chemically with metals, accelerate the dissolution of metals, shorten the service life of equipment, and increase equipment replacement and maintenance costs. For example, in acidic water, iron will react with hydrogen ions and continue to corrode steel pipes. Scaling: When the pH value is too high, the water is alkaline, which may cause calcium, magnesium and other ions in the water to form insoluble precipitates and scale on the surface of pipes and equipment. Scaling will reduce the heat transfer efficiency of equipment and increase energy consumption. For example, scaling in a boiler will affect heat transfer, waste fuel, and in severe cases may cause safety accidents. Affecting the effect of metal corrosion protection Industrial water with excessive pH value will affect the effect of metal corrosion protection measures. For example, some anti-corrosion coatings can only work best within a specific pH range. When the pH value of water exceeds this range, the protective performance of the coating will decrease, making the metal more susceptible to corrosion. Impact on production process Affecting the progress and quality of chemical reactions In the chemical industry, many chemical reactions are very sensitive to the pH value of water. Changes in pH will directly affect the rate, direction and quality of the reaction. For example, in some acid-base neutralization reactions, if the pH value of water does not meet the reaction requirements, it may lead to incomplete reactions or the generation of by-products, thus affecting the purity and performance of the product. Impact on water treatment process During the presentment and purification of industrial water, the pH value will affect the effects of processes such as accumulation, precipitation, and filtration. For example, in the accumulation process, the appropriate pH value can make the coagulant work better and remove suspended matter and impurities in the water. If the pH value is not appropriate, the accumulation effect will deteriorate, resulting in substandard water purification. Impact on product quality Change product properties For some industrial products that use water as raw material or participate in the production process, the pH value of water will directly affect the properties and quality of the product. For example, in the paper-making industry, the pH value of water will affect the strength, color and durability of paper; in the food and beverage industry, the pH value will affect the taste, shelf life and stability of the product. Impact on product purity If the pH value of industrial water is unstable or does not meet production requirements, impurities may be introduced or the ingredients in the product may change, thus affecting the purity of the product. For example, in industries such as electronic chip manufacturing that have extremely high requirements for water quality, small changes in pH value may cause product defects and reduce the yield rate. Impact on microbial growth Promote or inhibit microbial growth Different microorganisms have different adaptability ranges to pH values. Changes in pH value in industrial water can affect the growth and reproduction of microorganisms. For example, in some industrial circulating water systems, if the pH value is appropriate, microorganisms may multiply in large numbers, leading to problems such as deterioration of water quality, pipe blockage and equipment corrosion. On the contrary, inappropriate pH values ​​may also inhibit the growth of beneficial microorganisms and affect the effectiveness of biological treatment processes. https://www.renkeer.com/what-is-the-water-ph/
