Can lime neutralization be carried out by adding dry powder directly in the neutralization tank? Is there any problem with that?
It’s possible, but the neutralization tank needs to be cleaned regularly; lime powder contains a certain amount of stones and debris.
It’s fine to use it as a makeshift solution. It is best to use a mixing tank: 1. Mixing is necessary, otherwise precipitation will occur. 2. Waste discharge must be taken into account; impurities and undissolved substances need to be removed to prevent pipe blockages. 3. Heating is important, as the solubility of lime depends on temperature.
Yes, it’s better to have a mixer, with a plate and frame filter press at the back end
If something that causes precipitation, such as sulfuric acid, is involved, it is necessary to not only stir but also calculate the solid content; when the solid content is too high, discharging the material becomes a problem
