Abstract (English):
The problem of drinking water quality has been and remains one of the main problems not only in Russia, but also throughout the world. At the same time, it is worth noting that the reconstruction and modernization of existing water treatment facilities, the construction of new ones using effective modern water treatment methods, improves the efficiency and productivity of water treatment facilities. At the same time, the deterioration of urban water supply networks leads to repeated contamination of tap water, which leads to the need to use household water treatment plants. The most common methods of additional purification of tap water today are the use of household jug-type filters. At the same time, a wide variety of brands puts the buyer before the need to select and comparatively analyze the products used. Most often, jug filters are used for additional purification of tap water from residual chlorine, calcium ions, magnesium, and iron. The latter enter the water as a result of its transportation through worn-out city water supply pipelines. The most common brands of jug filters were selected for research. The tests were carried out on samples of tap water taken in various regions of Kazan. The iron content in the initial water and water purified in pitcher filters was determined by photocalorimetry using the method described in GOST 4011-72. The results of the experiment allowed us to establish that the cleaning efficiency depends on the type of pitcher filter used. At the same time, it was shown that for both filters, a reduction in iron content of 35-70% is achieved.
