Treatment of spent potassium hydroxide alkaline solution
Thread Content
When potassium hydroxide is used as a catalyst, 32% of the resulting waste alkaline solution contains many impurities. May I ask what methods can be used to filter this kind of waste alkaline solution?
What kind of impurities, solid particles or solutions? Is the purpose of separation to discharge them or to recover them? It’s impossible to resolve something that’s not clear
Liquid potassium hydroxide, containing solid particles such as iron
The common filtration method in factories is pressure filtration, while in laboratories it is suction filtration
What is the approximate solid-liquid ratio? How much is this amount? If it’s small, direct filtration by suction can be used; if it’s large, filtering equipment is necessary. What are the properties of the particles as well? Try membrane filtration; it works well. After filtering, rinse the waste residue directly, and take the waste liquid to mix it with other acidic wastewater.
Where is the poster? I can acquire it.
Purchase on behalf? Do you mean you want to buy it? . . . .
I’ll buy it. Where are you? Check if the distance is far.
It is generally an organic compound; I know that in alkyne reactions, potassium hydroxide is used as a catalyst, and the base is washed away with water, and treatment can be carried out through filtration and extraction.
Our company has about 22% sodium hydroxide solution – are you interested in it? ? ? ? ? ? ? ?
How to wash it with water/??????
