Execution standards for chemicals used in water treatment
Thread Content
I would like to ask everyone: for the chemicals used in circulating water, such as sulfuric acid and sodium bisulfite, should the standards applied be those for chemical reagents or those for industrial-grade products? Thank you!
It is generally at the industrial grade standard. Food-grade ones are too expensive; the cost is too high. Unless there are other special requirements.
Industrial-grade standards are sufficient to meet the requirements; chemical reagents of analytical purity are generally used in research fields in small quantities. As for food-grade chemicals, they are generally used in the food industry and are added directly to the production line
They are generally industrial-grade. However, sometimes it is necessary to take into account the water treatment requirements as well as the specifications of the chemicals, and consider them together.
