Opis:: The study was conducted to assess the effectiveness of wastewater treatment at the municipal wastewater treatment plant in Wolbrom, to which predominantly domestic wastewater and industrial sewage flow. The assessment was made based on the analysis of the physical and chemical research results of raw and treated wastewater. The research was carried out in the period from January 2014 to December 2014. To perform the analysis of the treatment plant efficiency, four indicators of wastewater pollutants such as BOD5 , COD, total nitrogen and total phosphorus were selected for further investigation. For each of the indicators degrees of reduction and coefficients of treatment plant operational reliability were calculated. The calculated degrees of reduction for each of the indicators were high and amounted to 99.0% for BOD5 , 95.2% for COD, 91.0% for total nitrogen and 91.6%. for total phosphorus. These results prove the effective reduction in the amount of pollutants. The determined coefficients of treatment plant operational reliability were at a low level: BOD5 - 0.27, COD - 0.44, total nitrogen - 0.33 and total phosphorus - 0.53. The conducted analyses prove the effective operation of the treatment plant, which was confirmed by high efficiency of pollutants removal.

Opis:: Municipal wastewater is characterized by diverse microbial content, largely dependent on their sources as well as many other factors like condition and health of their producer, but also environmental factors. The number and share of individual bacterial population in wastewater is changing during the process of their treatment in wastewater treatment plants. The microbial content of treated wastewater is significantly affected by the type of technology used for wastewater treatment. The paper presents the results of the species composition of bacteria present in the wastewater at various stages of treatment for the two different technologies. Samples of wastewater from hydroponic wastewater treatment plant and from the plant whose technology is based on biofilters were analysed. A key mechanism for wastewater treatment in both cases is biological treatment, using microbial activity that decomposes pollutants in the wastewater, which significantly contributes to changes in the species composition of bacteria comparing to microbiological composition of sewage flowing into the treatment plant. Analyses of microbial composition showed that in the objects consisting of preliminary tank and biofilter, composition of bacteria species is changing, but many species isolated from raw sewage is also found in treated wastewater. In the plant with hydroponic lagoon after wastewater treatment throughout the process system, bacteria present in raw sewage or in wastewater after biological treatment were not identified in the outlet.

Opis:: Adsorption is one of the basic surface phenomena involving saturation of the adsorbent surface with adsorbate molecules located near the adsorbent-adsorbate interface. The processes that are accompanied by the accumulation of adsorbate molecules on the surface are different from absorption, which is related to absorbing molecules into the whole mass and requires diffusion into the interior. If both processes can occur simultaneously, this phenomenon is called sorption. The aim of the present study was to characterize the sorption properties of selected sorbents and to assess the possibility of their application to support the treatment of coking wastewater from ammonium nitrogen, phenol, and TOC. The scope of the study included the examinations of sorption properties of selected sorbents (coal dust, coke dust, biochar), physicochemical tests of coking wastewater after biological treatment, as well as the examinations aimed to determine the dose of adsorbents and time needed to establish the equilibrium state of the process. The results obtained were analyzed for the effect of dose and contact time on the pollutant removal efficiency. The literature describes the efficiency of ammonium nitrogen removal from wastewater using chemical processes. However, there is a lack of studies on the removal of ammonium nitrogen, phenol, and TOC from industrial (coking) wastewater. The conducted study aimed to develop an alternative solution to the currently used conventional methods of removing high concentrations of pollutants from wastewater.

Opis:: The paper presents the current state of water supply and sewerage infrastructure and the need for its expanding in Radzyń district. The district is located in the northern part of Lublin Voivodeship in Poland. The following communes belong to Radzyń district: the municipal commune of Radzyń Podlaski and 7 rural communes: Borki, Czemierniki, Kąkolewnica, Komarówka Podlaska, Radzyń Podlaski, Ulan-Majorat, Wohyń. The data show that the water supply network in Radzyń district is well developed. The most significant percentage of the population using the water supply network has the rural commune of Radzyń Podlaski – 99.9%, while the smallest, commune Komarówka Podlaska – 54.5%. The survey showed that there was a very large disproportion between the development of the sewerage and water supply systems. The largest percentage of the population using the sewerage network has the municipal commune of Radzyń Podlaski – 99.7%. The smallest percentage of users of collective sewage disposal systems was recorded in the rural commune of Radzyń Podlaski (7.2%). The commune of UlanMajorat does not have a sewerage system. The survey conducted in 2016 shows that 8 collective wastewater treatment plants operated in Radzyń district at that time. The total capacity of the treatment plants is over 5,300 m³/d. In 2016, Radzyń district had about 1,000 household wastewater treatment plants. The presented data show that the condition of the sanitary infrastructure in rural communes of Radzyń district is unsatisfactory and requires the investment activities mainly aimed at expanding collective sewage disposal and treatment systems as well as developing a network of household wastewater treatment plants.

Opis:: The objective of this work was to test the impact of coagulant and flocculant at the stage of mechanical wastewater treatment on the wastewater treatment plant operation, performed in the A2O process. In this paper, the principles of correct conduct of coagulation in wastewater treatment have been discussed. It appears from the research performed that significant elimination of BOD₅ such as 20÷30%, total suspended matter up to 90%, COD up to 50% and total nitrogen at 30% level was achieved supported by the coagulation process in the pre-settling tanks. Approximately 50% of phosphorus was eliminated after the mechanical part. Additionally, a significant impact of Superfloc flocculant on the effectiveness of the solid phase separation (activated sludge) in the secondary settling tank was noted under diversified flow conditions.

Opis:: The construction of the technological treatment plant is closely related to the amount and physicochemical parameters of incoming sewage. The economic aspects and the principles of sustainable development also should be taken into account at the stage of sewage treatment plant construction planning. Moreover, in large cities, there is often greater number of sewage treatment plants, which should create an effective system for wastewater treatment. Municipal wastewater treatment system should not disturb the ecological balance of the area and cannot contribute to the deterioration of the living conditions of people (especially those living in the immediate vicinity of the sewage treatment plant). The paper compares the process lines of three wastewater treatment plants located in the city of Bytom: “Centralna” plant, “Miechowice” plant and “Bobrek” plant. The paper also compares the main indicators of the efficiency of the described wastewater treatment plants and the selected parameters of the sewage sludge. Based on the above data, an attempt was made to assess the proper operation of the sewage treatment system in the city of Bytom.
Budowa ciągu technologicznego oczyszczalni jest ściśle powiązana z ilością i parametrami fizykochemicznymi dopływających ścieków. Na etapie planowania należy rozważyć także kryteria zrównoważonego rozwoju oraz aspekty ekonomiczne. Ponadto, w dużych miastach na skuteczny system oczyszczania ścieków składa się często większa liczba oczyszczalni. Miejski system oczyszczania ścieków nie może zakłócać równowagi ekosystemowej danego obszaru ani przyczyniać się do pogorszenia warunków bytowania ludzi (szczególnie tych mieszkających w bezpośrednim sąsiedztwie oczyszczalni ścieków). W artykule porównano ciągi technologiczne trzech oczyszczalni ścieków znajdujących się na terenie miasta Bytom: Oczyszczalni „Centralna”, Oczyszczalni „Miechowice” oraz Oczyszczalni „Bobrek”. Zestawiono także główne wskaźniki efektywności oczyszczania oraz niektóre parametry osadu czynnego. Na podstawie powyższych danych podjęto próbę oceny prawidłowego funkcjonowania systemu oczyszczania ścieków w Bytomiu.

Opis:: The increasing demand for water with the industrialisation of the world is becoming a major problem as there is a water shortage all over the earth. Therefore, the water problem is one of the important problems that need to be effectively solved. This paper presents the results of research on wastewater treatment of bitumen production in the Mangystau region, which after physical and chemical treatment methods is sent to natural evaporation fields. As a result of research work, a method of wastewater treatment of bitumen plant was developed, which includes two stages: distillation of water on the solar plant and ozonation in order to oxidize volatile organic matter. Distillation to obtain primary treated water of 70–75% volume was carried out at 33–37 °C ambient temperature and 15–30 kPa rarefaction, at the same time COD of water was reduced by 68%.

Opis:: Pesticide pollution is a serious problem being faced. Harmful levels of pesticides are found in the water which is used for daily purposes. In the event of such a scenario, this paper presents a working solution for bringing down the Pesticide levels in the water to safe levels by using the method of liquid-liquid extraction. The experimental liquid-liquid equilibrium data on pesticide-water-solvent ternary mixtures at a temperature of 288.15 K are presented here. The pesticide used here is a chlorinated hydrocarbon called lindane found in the water (underground, land), beverages and foods. The solvents used are Petro-ether-Chloroform (1:1), Ethylene di chloride and n-hexane. The equilibrium generation diagram, triangular diagram, tie lines and bimodal curves as well as the distribution coefficient have been determined and reported. The petro-ether-chloroform was found to be the right solvent for the separation of lindane from wastewater because of high selectivity (25.36) and distribution coefficient (4). The extraction process is simulated into ‘C’ language.

Opis:: In this studies the influence of the dose and ratio of chemical reagents (Fe²⁺ and H₂O₂) on the efficiency of COD removal and changes of BOD₅/COD ratio in landfill leachate was analysed. The molar Fe2+/H₂O₂ ratio was lower than 1 and amounted to: 1:10, 1:5, 1:3, three research series with 1; 2.5 and 5 g/L Fe²⁺ concentration. A higher efficiency in removing BOD than COD, and therefore the decrease of BOD₅/COD ratio in effluent was stated. The efficiency of COD removal from leachate was from 58.34% (Fe²⁺ 0.5 g/L, Fe2²⁺/H₂O₂ 1:5) to 8.33% (Fe²⁺ = 0.1 g/L, Fe2+/H₂O₂ = 1:10), while the efficiency of BOD removal ranged from 62 to 77%. With the molar ratio Fe²⁺/H₂O₂ equal 1:5 the BOD₅/COD ratio was the largest for each of the analysed Fe²⁺ doses. The lowest BOD₅/COD ratio was observed for the Fe²⁺ dose 0.1 g/L and molar ratio of reagents 1:3.

Opis:: The paper presents the results of the study on reliability of the "Wastewater Treatment Plant (WWTP) – Receiver" system, using different models for predicting probability that the river will stay in the required purity class after receiving the discharge from a WWTP. A probabilistic model based on the total probability theorem and Monte Carlo (MC) simulations of the water quality below the wastewater discharge were used. The results show that probabilistic model generates lower values of "WWTP-Receiver" system’s reliability than the MC simulations. The results from the MC model may give more realistic values, being able to reflect the stochastic nature of the process, also showing that for the overall reliability of the "WWTP-Receiver" system – the quality of the receiver is a more sensitive factor than the WWTP’s reliability.

Opis:: The study aimed to assess the operation of the mechanical and biological wastewater treatment plant in Michów (Poland) in terms of the effectiveness of removing contaminants from mixed wastewater (dairy and domestic) and technological reliability. The wastewater treatment plant is owned by the Dairy Cooperative “Michowianka”. It is intended to treat mixed sewage, consisting of technological and sanitary sewage as well as part of rainwater from the plant, domestic wastewater supplied by a sewerage system from Michów, and wastewater delivered from septic tanks. In 2017 and in the first quarter of 2018, the permeate from the whey thickening process was also sent to the treatment plant. The period 2017-2021 was covered by the analysis. The analysis included the indicators from the fundamental group (TSS, BOD5, COD), biogenic indices (total phosphorus, total nitrogen, and ammonium nitrogen). The applied technology ensured the removal of total suspended solids, BOD5, and COD at the level of over 96%. Total phosphorus was removed with an average efficiency of 91%. Slightly lower effects were found in the elimination of total nitrogen – 78.5% on average, while the ammonium nitrogen removal rate was 88% on average. Due to the high efficiency of the facility, the values of the standard contamination indicators at the outflow, as a rule, met the requirements specified in the water permit. The technological reliability of the wastewater treatment plant in Michów, determined by the Weibull method, was at a high level, usually exceeding 90%. The reliability analysis shows that the facility in Michów has a high capacity to treat wastewater to the extent required for the wastewater receiver, and that the treated wastewater discharge does not cause negative changes in the environment. It indicates a high probability of obtaining the wastewater quality at the outflow from the treatment plant meeting the water permit requirements.

Opis:: The aim of this paper was to present the current state and the need for development of the sanitary infrastructure in the communes of the Ryki District located in the Lublin Voivodeship. The Ryki District encompasses 1 urban Commune – Dęblin, 1 urban-rural Commune – Ryki and 4 rural communes: Kłoczew, Nowodwór, Stężyca and Ułęż. The paper is based on the data from the surveys conducted in all the afore-mentioned communes in 2016. In the whole district on average 71.3% of the population used the water supply network, while 42% of the inhabitants were able to discharge wastewater to the sewage system. Within the area of the Ryki District, 5 collective wastewater treatment plants with a capacity exceeding 5 m3/d functioned in 2016. The households which were not connected to the sewage network discharged wastewater mainly to non-return tanks. About 440 household sewage treatment plants were found in the surveyed communes. The overwhelming majority of such small objects in the discussed district were activated sludge systems (92%). The research carried out in 2016 proved a strong need to develop the current state of the sanitary infrastructure in the Ryki District. A particular emphasis should be placed on the wastewater management by connecting the inhabitants of urban areas to a joint sewage disposal system. Ecological awareness must be raised so as to encourage people to invest in household wastewater treatment plants, which should be used in the areas with scattered development.
