Utility Water
For internal applications, more and more utility water is treated and re-used in order to save precious drinking water and reduce costs, so as is often done for example, in the food industry. The efforts for water treatment vary according to the quality of the raw water.
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.
