I’ve worked on an Alfa Laval EcoStream, which looks to be a really similar piece of equipment.
Cleaning a disk stack is a lot easier than cleaning/replacing a coalescer, or replacing a sand/carbon setup. Don’t have to dispose of drums of OWS waste…
It’s an Alfa Laval manual so it contains nearly everything from rebuild to troubleshooting.
I liked working on that Ecostream a lot more than I like pulling covers and changing paper filters, Brillo pad rolls, sand and charcoal.
