“…The increase in concentration of Σ THM may be affected by the use of UV rays before chemical disinfection. According to the research conducted by Włodyka-Bergier and Bergier [5] as well as other authors [19][20][21], water disinfection by means of UV lamps combined with later chlorination can lead to an increased potential to form disinfection by-products, including compounds from the group of trihalomethanes. It has also been shown that chemical oxidation (such as ozonation) conducted earlier on in the process can affect the formation potential of these compounds.…”

The article assesses the effects of use of ultraviolet radiation and electrolytically generated sodium hypochlorite on the quality of drinking water produced at “Raba” plant of the Municipal Water and Sewerage Company in Cracow as well as in the water supply network. The analysis included selected microbiological indicators, total organic carbon, water chlorination products from the group of trihalomethanes and free chlorine. The research conducted indicated that disinfectant change caused quantitative changes in THMs and free chlorine in water supplied to the water supply network. After an upgrade of the chlorination plant in 2014, an increase in water disinfection by-products at most of the tested points of the water supply network was observed. A sudden decrease in free chlorine in the distribution system was also observed in that period, whereas a bacteriological water analysis confirmed the effectiveness of use of the new water disinfection technology.

“…Nonetheless, the absence of a disinfectant remaining in the water can promote secondary contamination in the distribution network. Therefore, this technique is most often used in combination with chlorination using sodium hypochlorite, chloramination or disinfection by means of chlorine dioxide [1][2][3][4][5].…”

“…The solutions applied, however, are not compact and modular and are difficult to assemble and use, especially if there is a need for modernization. Sometimes an undesirable chemical treatment is used, which can affect fauna and flora [25], or UV lamps are utilized, which destroy as much as 90% of microbes, including useful ones playing an important role in improving water quality [26].…”

Natural swimming ponds using treatment wetlands (TWs) as an element of treatment of swimming water are an ecologically beneficial alternative to conventional pools. Unlike conventional swimming pools, in natural swimming ponds, the water treatment avoids the use of chemical methods and is based on the phenomenon of water self-purification and the rhizofiltration capacity of repository macrophytes in TWs of the regeneration zone, as well as on typical physical filtering processes (e.g., straining, sedimentation, or flotation), physicochemical filtration (physical and chemical adsorption, mainly of phosphorus), and biological filtration (nitrification and denitrification). Market solutions usually arise from the implementation of water treatment solutions used in small garden ponds, which are not typical for ponds; moreover, they are expensive and difficult to use and maintain. Therefore, they require the development of a dedicated system that improves the functioning and usability of the filtration system. A modular, compact filtration system for the treatment of water by physical and biological methods, made of polymer composites and with replaceable filtration modules and essential equipment (e.g., skimmers, dispensers, and filtration mats), is a solution expected by many pond users. It enables the exploitation of the natural functions of ponds and contributes to the preservation of biodiversity and active recreation in a biologically living aquatic ecosystem.
