“…The high effectiveness of modern filtration technologies is mainly related to the high capacity of materials used as filter beds, and therefore the necessity of their effective washing and thus the management of large amounts of washings [11][12][13].…”

This paper presents the influence of the type of filtration beds, used in swimming pool water treatment systems, on the quality and the possibility of reuse of washings. The research covered 4 pool cycles with sand, sand and anthracite, glass and diatomaceous beds. The degree of contamination of washings was assessed on the basis of physical, chemical and bacteriological tests. The possibility of washings drainage into the natural environment was considered, and the results of the research were compared with the permissible values of pollution indicators for wastewater discharged to water or ground. A direct management of washings from the analysed filters proved impossible mainly due to the high content of TSS (total suspended solids) and free chlorine. Washings were subjected to sedimentation and then the supernatant was stirred intensively. As a result of these processes, the quality of washings was significantly improved. This allowed planning to supplement the pool water installations with systems for washings management.

“…If a water attack on the exposed metals can be characterized by its corrosion and influence against other surfaces, we can talk about its aggressiveness. Corrosion and aggressiveness of water are common problems, especially for the industrial production of boiler water [10,13].…”

“…This can also be achieved by water filtration through the masses increasing the water pH. If a suitable bed and filter parameters are selected, then other equipment can be used to remove aggressive carbon dioxide from the water, which is responsible for its corrosive properties [12][13][14]. According to Shock and Lytle [15], marble grit or roasted dolomite is the best choice for this purpose.…”

“…Furthermore, incorrectly purified water is able to damage many devices that stay in contact with it; that is, pipes, water pipe fitting, storage tanks, filters, boilers, and others. The result of a higher level of aggressiveness and corrosivity is elevated concentration of carbon dioxide and change of water color [11,13]. These were the problems of the studied industrial plant that needed clean and stable water to feed the high temperature boiler.…”

The aim of the study was the assessment of corrosivity and aggressiveness for boiler feed water. The negative effects of water corrosivity and aggressiveness may include silting up of the steel water supply system and the destruction of boiler equipment touched or washed by such water. They may cause the whole industrial production system to fail or be destroyed. That is why it was important to reach a high water purification level, including the calculation of water aggressiveness and corrosivity indicators. The carried out test showed that the simple system used before the modernization of the industrial water treatment plant is not sufficient to reach clean and stable water. The authors proposed modernization, including additional processes to improve boiler water quality, and designed new devices for water treatment. As a result of the new idea, groundwater taken as raw water was treated in individual and complex processes, such as pre-aeration, filtration, ion exchange (cation and anion exchange resigns), extra aeration, and extra degassing. The conducted research included chemical analyses of raw and treated water. In the conducted studies, the indirect method of water aggressiveness and corrosivity assessment was applied using mathematical calculation of the Langelier Saturation Index (LSI), the Ryznar Stability Index (RI), the Larson–Skold Index (LI), and the Singley Index (SI). The results proved that the new proposed processes for the boiler feed water treatment station allow reaching a high water quality and low level of water aggressiveness and corrosion.

“…The aim of the study was to optimize the process of water treatment at small-scale stations located in micro-agglomerations. Currently, in water treatment technology, there are applied physical processes such as filtration of water by special mineral deposits and chemical processes, such as aeration or the use of catalytic beds [4,5]. However, in real objects, the equipment used is not always properly fitted and calculated.…”

The goal of the research was to assess the pollution level of water in the existing real water treatment station in Pelele in the municipality of Punsk. The station needed to be rebuilt because the equipment in operation there had not been changed for years. As part of the research efforts, a new water purification system was designed. The technology of the station is based on a two-stage water treatment system. Water picked up directly from the intake (raw water) as well as purified water at the old and new stations were analyzed. Then, the results obtained from water tests before and after modernization of the station were compared. There were such parameters analyzed as: color, turbidity, pH, iron (Fe), and Manganese (Mn). Through the conducted research and the results of pollution parameters received, the levels of Fe and Mn in raw as well as treated water were revealed. Their concentrations have proven that water coming from the new station continues not to be appropriate for human consumption just after the modernization process.
