In an early video Lee Pryor made back in the beginning of 2012 he said that he used a Robak (spelling) which recycled about 50% of his waste water. He also uses a water softener.

I did ask him for some more detail but never got a reply.

There was also another post from someone who produces a massive amount a water daily. His system also recycles waste but he had to replace his 4040 membranes every 6 - 8 months (?). I can't find the post but it was an all in one portable trolley system.
