How could a biologically engineered body dump toxins from the blood stream?

Through a short amount of research it seems most blood is cleaned in the liver and most toxins are neutralized before being passed into urine or the bowels. If this is how most toxins are excreted from the body then what are some other ways of dumping toxins the liver can't destroy, assuming a race's technology has reached the point that modifying biology can be done relatively successfully? There are a few restrictions I'd like to put on answers if allowed:

• Since we know that most toxins are already dumped through the liver let's refrain from any answers using this method. We can just assume that doing this would over-work the liver or would otherwise be untenable.
• Secreting them out of the skin with sweat is acceptable but lets keep these types of answers to the minimum.
• In general I'm looking for answers that the body can not already do on its own, I'm looking for a creative or otherwise interesting new way to do it

I'm aware I'm asking more than one question here but I'd also like some input on a way I think would be quite theatrical but am not sure if it is anywhere near realistic. Tissues in the nose are rather thin, so would it be realistic for the bio-engineers to add a new organ near the nasal cavity that filters blood for toxins that the liver can't sift out and then eject these toxins through the membrane with mostly plasma and maybe a few red blood cells and hemoglobin? Or is this completely ridiculous/unnecessary? Tearing the membrane in the nose causing minor bleeding is acceptable in this case. To clarify the point of this question revolves around neutralizing toxins in a humans body through biological engineering, not through other things such as nanobots. If I haven't been clear enough I will be sure to come back and clarify.
