Lime dosing issue
Thread Content
I am handling a wastewater treatment project, and I plan to use coagulation and sedimentation as the main treatment process. Lime and ferrous sulfate will be used, in a ratio of 1:1, with relatively large amounts being added. Due to the severe dust emission that occurs during the dissolution, curing, and addition of lime powder, it can easily cause health hazards to the workers involved, as well as pollute the environment, which is contrary to the basic principles of environmental protection. I would like to ask my fellow water treatment professionals: are there any good methods for dissolution and addition?
Using slaked lime can solve this problem; if lime milk is available in the vicinity, there will be no dust at all.
Just make a dumping hopper; the reactor needs to be completely sealed.
Conditionally, add a feeding bin, and equip the feeding bin with a bag filter for dust removal.
It can also reduce lime slag, as quicklime contains many stones and such things.
Our equipment has also recently seen the use of lime powder in some applications. Thank you to everyone above for their suggestions.
Yes, now there are machines for adding it, so there’s no need for manual addition
If you are using slaked lime, it is recommended to install a storage bin along with a screw conveyor for automatic dosing; if you are using quicklime, a storage bin together with a hydraulic inclined screen can be used to prepare a sodium hydroxide solution for use
I have installed several lime systems recently, but your question is too vague
