Disinfection and Oxidation Systems

Our specialists can thus compose the procedure which is best suitable for the respective application. For the selection of a suitable disinfection and oxidation method, effort and benefits for the specific requirements are to be examined first. Here-fore, among others, the following topics are paid attention to:

• Strength of disinfection or oxidation
• Efforts for the chemical to be used 
• Energy input
• Generation of disinfection by-products

Means of Disinfection

	Chlorine	Chlorine dioxide	Ozone	UV
Depot effect	several hours	several days	several minutes	n.a.
Resources	Chlorine gas, Hypochlorite or Electrolysis (common salt)	HCl & NaClO2	Air or oxygen,electr. energy	electr. energy
Disinfection capacity	medium	strong	strongest	medium - strong
Dependence from pH value	extreme	none	low	none
DBP’s *	Trihalogen methanes, Chlorine amines, Chlorine phenoles a. other AOX, Chloride	Chlorite	Bromate in presence of Bromide	Nitrite in presence of Nitrate at medium pressure lamps

 * DBP’s  =  Disinfection By-Products

Means of Oxidation

		Chlorine	Chlorine dioxide	Ozone	UV
Oxidation	of metals e.g. Iron, Manganese, Arsenic in drinking water	+	+	+++	-
Oxidation	of organic pollutions in drinking water	-	+	+++	-
Oxidation	of malodours in air scrubbers	-	++	+++	-
Degradation	of Chlorine, Chlorine dioxide or Ozone in production waters	-	-	-	+++
