Can an electrodesalination and dehydration system remove the ash contained in oil products?

Can an electrodesalination and dewatering unit remove the large amount of ash contained in crude oil? Of course, it’s the type with an extremely high ash content, and it cannot be removed through filtration
From a practical application perspective, electrodialysis is very ineffective at removing ash; based on observations on site, ash particles smaller than 100 microns basically do not get removed.
Are there any good ways to remove the ash content?
The option is centrifugation, but the cost is high. I think using filtration could also be a solution; however, cleaning the filters is an issue that is still under investigation. If it’s really urgent, I believe using a filter after the primary separation step could work – pressurized steam condensate can be used to backwash the filter at the bottom of the secondary tank. Under normal conditions, a new filter lasts for 2 hours; if it is rinsed thoroughly, it should last for 1 hour
