What additives are used for flue gas desulfurization water treatment
Thread Content
What additives are used for flue gas desulfurization water treatment? We currently use solid polyaluminum chloride and polyacrylamide, which are then mixed into a liquid form before being injected. I’ve heard of liquid additives as well; the effects of these two types of additives combine in such liquids. Which one do you use, and what are its advantages and disadvantages?
Using a specialized flocculant gives very good results!
Just like here, it’s these two types of solid treatment agents; the treatment effect is fairly good, and there’s a noticeable difference whether they are used or not
Mainly flocculants and coagulant aids. For liquids, the manufacturer prepares the mixture in advance, so it can be simply poured in – this saves labor involved in mixing and reduces mixing errors. The principle is the same in all cases.
At present, we still use aluminum chloride polymer and flocculants that are added separately; they are in powder form. Some companies have started using liquid additives that combine aluminum chloride and flocculants together, and the results obtained with these are better than those achieved with powders. However, their price and the amount required for application are higher than before
