Disinfection for the product water of a reverse osmosis unit

摘要

In a process for operating a very small osmosis unit which can produce approximately 10-50 l/d of product water from feed raw water in a reverse osmosis module in a virtually constant product water stream, the virtually constant product water stream is heated to approximately 70 DEG C-90 DEG C. By this means the product water of the very small osmosis unit can be inexpensively disinfected and without hazardous by-products in a technically simple and yet reliable manner.
