Hello,

 

I need to design a slurry filtration line, operated in batches.

There's some optimization work to reduce the total cycle time of the batch, if possible reduce/combine steps (ex.: oxidation and pH adjustement tank) and reduce number and volume of tanks.

 

Are there any approaches or tools I can look into?

 

Many thanks,

 

Quang-Danh

Hi,

Consider this paper about cycle time .

note : I don't think it's relevant to squeeze time during the chemical reaction process  . Kinetic and residence time are keys .

yes it's possible to have steps reduced with compact reactor where the stream overflows from one compartment to the other , basically a rectangular reactor. Ph adjustment , Fenton reaction and decantation  .

Lamellar decanter is also an option to reduce the size of the sludge compartment .

My view.

Good luck.

Thank you Breizh.

 

I agree that the kinetics will be one of the constraints for time.

In my case, I have holding tanks upstream of filter presses and before transferring to another precipitation/filtration step, so I think there's room for reduction.
