They suggest treating only 5-7% of the blood, which is 250 - 350 ml. It's still going to be an elaborate procedure, but a lot less so than hemodialysis, which moves much larger volumes of blood. You wouldn't even need a large-bore catheter, and keeping the blood pressure stable would be far less of a concern, so you probably don't have to do it 1:1.

Couldn't you treat the blood within the body? Find a high flow, easily accessibly blood vessel and inject a thin fiber optic cable connected to a uv laser?
