【Weekly Topic】- How to manage chemicals used in wastewater treatment
Thread Content
During the operation of wastewater treatment, many chemicals are used, including both solid and liquid forms. Some of these chemicals are ordinary, while others are corrosive (such as acids and bases); there are also those with high water absorption properties (such as PAM and ferrous sulfate). How are these chemicals stored and managed?
Our sulfuric acid and liquid caustic are stored in 30-cubic-meter storage tanks.
We use membrane treatment and biological treatment. No medication needed, hehe
Stored in sulfuric acid and liquid caustic storage tanks. But inspections will be carried out. . . As for PAM and PAC, store them in a cool and dry warehouse. . . Of course, there are also inspections. . . .

Solids and liquids should be stored separately; acids and bases should not be kept together, nor should different products be mixed. Each type of product requires specific handling methods – for example, ferrous compounds should be stored in a dry and cool place. Special attention should be paid to hazardous materials; in fact, different products have various storage requirements. It is recommended that corrosive substances be stored in a way that prevents corrosion, and appropriate hazard labels should be used.
Alkalis, mainly caustic soda； Slow-release scale inhibitors, bactericides, algaecides, etc. should be stored in a cool and well-ventilated place, with labels attached
When storing and using PAM, attention must be paid to its tendency to absorb moisture and undergo hydrolysis; it should not be left exposed to air with its container open, nor should it be left standing after being dissolved – it should be prepared just before use.
For liquids, such as corrosion and scale inhibitors, bactericides and algaecides, as well as corrosive liquids like liquid alkali, they can be stored in a well-ventilated warehouse; of course, proper safety measures must be taken and regular inspections carried out. As for solids that are corrosive, such as bleach, caustic soda, dichlorine, etc., they should be stored in a dry warehouse. These products should not be mixed with agents like polyaluminum chloride and polyacrylamide to prevent problems
Does ferrous sulfate have any other functions besides flocculation?
