Materials of equipment for softening water

The material selection for soft water storage tanks typically takes the following factors into consideration: 1. Water quality inside the tank: Soft water reduces the formation of scale by removing hardness components such as calcium and magnesium ions. Softened water will be purer, but it may also be more corrosive. 2. Working environment: Consider the chemicals and potential corrosive substances that may be present in the factory environment. 3. Cost issue: Stainless steels made of different materials have varying prices; generally, the higher the grade of the steel, the better its corrosion resistance, and the higher its price as well. 4. Corrosivity: Different stainless steel grades have varying resistance to corrosion. Generally speaking, 304 stainless steel already possesses good corrosion resistance, making it suitable for storing softened water in most ordinary environments. It contains high levels of nickel and chromium, and can meet the requirements of most water softening systems. 316 stainless steel offers better corrosion resistance than 304, as it contains molybdenum, which provides enhanced corrosion resistance. If the chloride content in the softened water is high, or if the storage tank operates under more severe conditions such as higher temperatures or in an environment with other corrosive chemicals present, then 316 stainless steel would be a better choice. In summary, the choice between 304 and 316 stainless steel depends on the specific application environment and cost budget. If the environmental conditions are not particularly harsh or the budget is limited, 304 stainless steel is generally sufficient. However, if the environment in which the demineralized water is used is particularly corrosive, or higher durability requirements are placed on the storage tanks, it may be necessary to choose the more expensive 316 stainless steel. It is advisable to consult professional water treatment engineers or tank manufacturers for advice before making a decision. .

Industrial boilers and desalination tanks for process water generally use steel-lined fiberglass or steel-lined rubber. Secondary deionized water is used in 304 stainless steel water tanks, while 316 stainless steel is used in the food and pharmaceutical industries, right? The water storage tank can be quite large, and using all stainless steel makes it expensive to construct. It is sufficient as long as it meets the requirements for the quality of demineralized water.
