Strongly polluted water needs to be first filtrated, possible bio mass must be separated in a bio reactor, then reverse osmosis is often applied. Additionally, the water must be sterilized. For this purpose Chlorine dioxide is often used which, with its remanence effect, prevents quick re-germination.
For less contaminated water or the lower requirements of utility water, sole disinfection with Ozone or Chlorine dioxide may be sufficient. The latter is a very appropriate and cost-effective solution, for example the treatment of exhaust vapors. The treatment and re-use of utility water enables substantial cost savings amortizing the investment in record time. |
