How is calcium sulfate precipitated?
Thread Content
Which precipitation method is best for the calcium sulfate produced as a result of neutralization? We are currently using the inclined-tube method, but it’s not effective – it gets clogged within a few days. I’ve heard that increasing the taper of the radial-flow type can yield better results Which TX would you like to introduce?
Calcium sulfate should form scale on the components; it is advisable to use precipitators and clarifiers with simple structures! ! !
The second floor is the correct choice; air flotation can also be used. Of course, radial flow sedimentation tanks work well as well, but air flotation provides a better sedimentation effect.
Air flotation won’t work, right?! I asked those who manufacture air flotation equipment – calcium sulfate has too high a specific gravity, so it can’t float. Right?
The inclined tube sedimentation system on the upper floor needs to be cleaned; if it tends to get clogged, cleaning it more frequently will be necessary. You can try using a vertical flow sedimentation tower – such systems are less likely to experience clogging
What is a good taper for a radial flow design?
Do not use inclined tubes; make the sedimentation tank have a shallower gradient, and a sludge scraper can be installed.
Thick + filtered – a great way to handle it
The compressive density of calcium sulfate is very low, at around 20% only; therefore, it is not suitable for treatment with adhesive tape after being compacted A large area of tape filtration is required, which makes it uneconomical; moreover, the moisture content of the filter cake is very high, exceeding 50%. There is currently no good treatment method or process available!
