Abstract

The results of the study of water disinfection using UV radiation in combination with other physical and chemical methods are shown in the article.

Combined use of the different decontamination methods is expedient in cases where one of the methods hasn’t the requisite properties.

In assessing the effect of the combined action of chlorine and UV disinfection it is shown no disinfection enhancement. Also, photolysis of chlorine compounds is not accompanied by the formation of undesirable byproducts.

Combined use of US and UV treatment is characterized by high energy consumption, which makes this method not competitive for industrial use.

Using high frequency currents entails higher costs in comparison with traditional method and therefore this method is not practical for widespread use.

Using water ozonation provides the primary barrier against microbial contamination and reduces the amount of reagent that enables the use of the method for decomposition of complex organic compounds.

Combined methods of UV radiation and other physical and chemical techniques (ultrasound, chlorination, microwaves) make it possible to solve complex and specific problems on a laboratory scale. Ozonation with UV radiation can be used for industrial purposes.

The effectiveness of each of the studied techniques is based on the results of bacteriological analysis and characteristics of the object. The proposed UV combined methods for germicidal disinfection can be used for disinfection of not only drinking water and wastewater, and for a variety of objects of agriculture, food and medical industries.
