A model of a waste treatment-water reuse system predicts the maximum build-up of organic carbon and total dissolved solids in recycled water at a large number of recycle passes and the predictions are validated experimentally. A toxicity and irritancy (dermal, ocular, and oral) study on mice and rabbits with various concentrated ultrafiltrates and feed solutions showed that the recycle water can be reused for human contact purposes with a large safety factor (100:1), even at a very high number of recycle passes. The animal studies are validated by human skin irritancy tests.
