Water treatment and disinfection in outdoor conditions
 Hrušková, Barbora ; Načeradská, Jana (advisor) ; Petříček, Radim (referee)
Travel to countries with inadequate sanitation facilities or to the wild involves the risk of contracting pathogenic organisms. There are several options for providing hygienic drinking water in field conditions. The main objective of this paper is to present these options to the reader, to evaluate the advantages and disadvantages of different types of water treatment and disinfection in the field, and to assess the health risk of consuming water treated in field conditions. For while there are a large number of studies on water treatment in water treatment plants, there are few studies on water treatment under field conditions, and in particular the generation of disinfection by-products (DBPs) during field water disinfection. One method to treat water in the field is the use of filtration. Filters can remove suspended solids and bacteria from water due to membranes with pore sizes of about 0.2 μm. The advantage of filters is that they do not encourage the formation of DBPs. On the other hand, 0.2 μm pore sizes may not stop all pathogens. Disinfection with UV light has been shown to be effective, but in turbid water the effectiveness decreases. It is recommended to stir the water with a UV lamp to improve the disinfection results. UV does not produce DBPs, which is an undeniable advantage of this...
