scrubber for water

[PreciousMexpert]

Now that we have made a scrubber for acid fumes the idea to make a scrubber for the treatment of water must be similar

I saw a company doing this
Can anyone tell me how this is done

air and water quality control systems for the treatment of odors, corrosive
fumes and toxic gas in industrial and municipal applications.

Since these scrubber balls are used by fish farms than I guess you can make it happen
I am not an expert
I dont know how
