For adjusting the pH in applications requiring large volumes of water, a relatively high level of precision is needed. However, building water tanks is too costly and there’s no suitable location for them. Is there any better solution?
To address the issue of adjusting pH for large volumes of water, you can consider using chemical additives or electrochemical methods for adjustment. Among them, chemical additives can be precisely controlled through automatic control systems, but the cost of use and their impact on the environment need to be taken into consideration. Electrochemical methods can adjust the pH of water through electrolysis; their advantage is that they are simple to operate and do not pollute the water quality. However, they require an initial investment in equipment as well as regular maintenance. Depending on the circumstances, choose a method suitable for you to adjust the pH at large volumes. -
What is the volume of water? What is the level of precision? Please specify those conditions clearly.
20,000 tons per day, with the pH adjusted using acid from neutral to 3, requiring a small range of variation
With such a large volume, the only option is to dig a pool and add chemicals there; building storage tanks requires a lot of space, so it’s better to dig a pool instead.
You know, this figure is absolutely absurd 20,000 tons per day is 830 cubic meters per hour. As pH drops from 7 to 3, the molar concentration of hydrogen ions reaches 0.001 mol/L. It is prepared using concentrated sulfuric acid, with 40 tons of sulfuric acid having to be added per hour. Not to mention one’s own property; if buying, an extra load is charged per hour. What is this project?
That’s right, it’s 40 kg. Mol gives the value in grams; I got the unit wrong
Your water volume is too large, and the pH range is also wide; a large amount of acid is required. How can high precision be achieved if it isn’t adjusted in a stable environment?
If the water quality and volume are very stable, it is theoretically possible to precisely add chemicals to the pipeline through an automatic control system (it is advisable to use a pipeline mixer for this purpose).
