Degermination methods Comparison

Water-disinfection ist the elimination or deactivation of organisms that cause contagious diseases. Degermination is the elimination and seperation of microorganisms – especially bacteria – through physical or chemical procedures.
Usual degermination processes are water-treatment with ozone, chlorine dioxide, chloric gas or dechlorinated chemicals as well as UV-radiation as a physical preparation procedure.
Which procedure is chosen is depended on water-quality, amount and additional preparation methods.
There is a variety of techniques to disinfect water. Every technique has its specific advantages and its own application area. The chart shown below contains advantages and disadvantages of various techniques:
Technology  Environment  Efficiency  Investment  Operating- costs  
Ozone + + + - +
Chlorine dioxide +/ - + + + + +
Chloric gas - - - + + +
Hypochlorite - - - + + +

The best technique is no use if it doesn’t suit the person who handles it. What looks easy in the end is the result of a comprehensive development- and improvement-process.
