Opis:: The main aim of the paper was to formulate a proposal of using the draining barriers as a method of limiting pollutants in the groundwater reservoir. Primary processes of pollutants migration and examples of functioning the draining barriers work against the spread of various pollutants in the groundwater were indicated. An untypical kind of draining barrier, i.e. wells which were designed as a hydrogeological borehole to exhaust water intended for consumption, was selected as the research object. For analytical purposes, the available archival results of the physicochemical analysis of groundwater exhausted from the wells, located in the water intake so-called “belt D” in Kraków-Nowa Huta were used. The database was analysed by specialist programs, and the dispersion migration of pollutants from the existing metallurgical waste dump “Ruszcza” in time was presented. Temporary and spatial variability of the physicochemical parameters of groundwater was done during the analysis. The analysis was performed both in the draining barriers wells and in the intake boreholes. A geostatistical analysis of the variability of pollutant spread in the groundwater medium was a vital factor in the appraisal efficiency of the draining barriers operation. It was shown that the highest contents of the researched substances were present in the wells, which are located the nearest of metallurgical waste dump “Ruszcza” and are thereby the wells co-forming draining barriers. The efficiency of draining barriers was found after a thorough analysis.

Opis:: This paper presents the analysis and evaluation of the impact of clean sewage on the water in the Mordarka river, in the period 2012–2015. The analysis was conducted based on the collected and statistical research: the amount and composition of the purified sewage discharged to the receiver. The following pollution indices were tested: total suspended solids, BOD₅, COD, total nitrogen and total phosphorus. On the basis of the obtained results it was concluded that the amount of purified wastewater discharge to the Mordarka river, did not contribute to the degradation of the water quality in that period of time. Moreover, the level of indicators: total suspended solid, BOD₅ and COD did not exceed the limit values from the regulation, which confirmed the effective protection of water quality in the Mordarka river. However, because of the high concentration of biogenic compounds in the purified wastewater effluents, the river is prone to eutrophication process.

Opis:: The paper presents the results of the analysis concerning the verification of the actual hydraulic load and the load of organic pollutants compared to the conditions designed for 4 household wastewater treatment plants. The researches were carried out in the annual period from May 2015 to April 2016. Based on the conducted analysis, it was found that objects act as underloaded hydraulically and the actual inflow of sewage to the analysed objects during the research period ranged from 7.3% to 32.7% in relation to the inflow assumed in the project. Furthermore, in the case of loading the treatment plant with the load of pollutants expressed as PE, it was fund that the actual PE values were lower than assumed in the project. Therefore, it is important that the sizes of the series of household sewage treatment plants were selected depending on the individual conditions of household, i.e. the number of inhabitants or the amount of consumed water.
W pracy przedstawiono wyniki analizy dotyczące weryfikacji rzeczywistego obciążenia hydraulicznego oraz obciążenia ładunkiem zanieczyszczeń organicznych w porównaniu z warunkami projektowanymi dla czterech przydomowych oczyszczalni ścieków. Badania prowadzono w rocznym okresie – od maja 2015 r. do kwietnia 2016 r. Na podstawie przeprowadzonej analizy stwierdzono, że obiekty działają jako niedociążone hydraulicznie, a rzeczywisty dopływ ścieków do analizowanych obiektów w okresie badań wyniósł od 7,3% do 32,7% w stosunku do dopływu zakładanego w projekcie. Również w przypadku obciążenia oczyszczalni ładunkiem zanieczyszczeń wyrażonych jako RLM, stwierdzono, że rzeczywiste wartości RLM były niższe, niż zakładane w projekcie. Zatem ważne jest, aby wielkości typoszeregów przydomowych oczyszczalni ścieków były dobierane w zależności od indywidualnych uwarunkowań gospodarstw domowych, tj. liczby mieszkańców lub ilości zużywanej wody.

Opis:: The aim of the work was to determine the technological reliability of the selected pollution indicators removal BOD₅, COD_Cr and total suspension from the sewage treatment plant working with the bioreactor Pomiltek Mann type. Wastewater treatment plant which is a subject of this study is located in Lesser Poland, in Siepraw commune. The analysis was performed using the Weibull method for basic indicators of impurities, BOD₅, COD_Cr and total suspended solids. Physico-chemical analyses of raw and treated wastewater, were carried out in the period from 2003 to 2014 (11 years). The research period included measured values of pollutions indicators in 38 samples of raw and treated sewage. For each of pollution indicators descriptive statistic, percentage reduction (n) and treatment plant reliability factors (RF) were calculated. Average reduction for BOD₅ and TSS was on level equal 94%, only for COD the average reduction was lower and was on level 89%. The reliability values determined by Weibull method, were: 75% (BOD₅), 90% (COD_Cr) and 89.5% (TSS). The reliability results have been lower than the presented by literature source, which means that work of wastewater treatment plant in Siepraw was not satisfied in 11 years of research.
