Filtration by suction problem
Thread Content
I have a question for everyone. In our factory, wastewater desalination is carried out using a filtration tank, where a vacuum pump is used to remove the filtrate, and the remaining salts are extracted. The problem is that when using the vacuum pump on the vacuum tank to create a vacuum and draw out the filtrate, the filtrate is discharged through the vacuum pump. What is the principle behind this? In previous vacuuming processes, a vacuum buffer tank was used for discharging the liquid; so what is the principle behind discharging it directly through the vacuum pump now?
Is a jet vacuum pump being used?
It’s not a jet vacuum pump; it can also absorb liquids and discharge them together
Reply to 2# smlx1978: It uses a jet-type pump; I couldn’t see how it manages to discharge the liquid!
Reply to 3# zwm6666: It is a jet vacuum pump. What is the principle behind it? How is the liquid after filtration removed?
Reply to 5# smmfy: It’s very simple; the filtrate is discharged together with water and ends up in the water.
