Disinfection in water treatment

There are several methods for a proper disinfection of wastewater. It's good to know the characteristics of each of these technologies in order to choose the one best suited to treatment of water we want to perform.

The Ozonation
One option for disinfection is ozonation. Ozone, may spread in the air of wastewater directly reacting with organic matter. As a result, generated a series of chemical reactions involving radicals. Some of these reactions, have the ultimate effect of water disinfection. Generally, ozonation is effective in removing bacteria and virus groups. It also includes a number of advantages: eliminates odors, does not produce other dissolved solids, and has the ability to increase the oxygenation of the effluent without affecting its pH. The technique is performed in situ, using commercial kits. When the content of organic matter in water is very high, it takes comparatively high ozone dose to achieve a successful disinfection.
