If you're doing it in batches, yes and it's not quite as easy as many people think. There are many stages of degreasing, rinsing, acid etch baths, rinsing and so on, usually several tanks each with a rinse tank after before actually entering the final anodizing tank.
Preparation is the big thing and after polishing to remove the imperfections the many stages before the actual anodizing all take time.
If you're doing it yourself it can be reltively cheap but you'll be limited by what you can get from the mains supply you're using.
