Opis:: The cities of Iraq in general and the city of Al Diwaniyah in particular are characterized by the fact that the majority of households use septic tank to dispose of sewage, leading to contamination of ground and surface water and a disturbance to the environment. The objective of this study is to protect the water and soil sources from the risk of pollution, eliminate the process of perfusion and thus, reduce costs, maintain public health, as well as design and implement the proposed purification unit for domestic wastewater treatment. A domestic wastewater treatment unit has been improved to meet the standard specifications for the quality of the effluent wastewater. In this study, a compact non-electric sewage treatment unit was improved and implemented. Treatment is based on an effective modern biological purification process. Experimental verification and analysis of results were performed to demonstrate the improvement of physical and chemical parameters. The performance of the septic tanks-bioreactor gave satisfactory results. The removal efficiencies of Total Biochemical Oxygen Demand (BOD), Total Chemical Oxygen Demand (COD), NH4-N, Total Nitrogen and Total Suspended Solid (TSS) were 96.9%, 84.6%, 78.8%, 79.9% and 95.3%, respectively.

Opis:: The aim of the study was to verify the possibility of the existence of preferential flow paths in a septic tank and the effect of using various types of inlet and outlet in this context. Two of the most unfavourable variants of privileged flow paths for different types of inlet and outlet were analysed. The first variant was related to the occurrence of the privileged flow path below the water surface level directly to the outlet and the second variant – to the socalled boiling phenomenon in a septic tank. During the study, the intensity of outflow from the septic tank was measured. The time between successive doses also was measured. These studies were carried out using several inlet and outlet structures combinations. It was observed that by introducing a suitable outlet it is possible to limit and in the case of the particular type of filtering basket – to eliminate the unwanted phenomenon of preferential flow paths after hot water introduction. The phenomenon of boiling in the septic tank may occur due to the introduction of wastewater of higher density containing a higher concentration of the suspension. The effect of cooler water introduction on this phenomenon was not observed. The limitation of the maximum intensity of outflow from the septic tank can be achieved by filtering basket using at the outlet, which increases the flow resistance thanks to the low porosity.

Opis:: The aim of the work is to present the current state of water and wastewater management in the municipalities where the Polesie National Park (PNP) is located. The PNP is situated in Lublin Voivodeship, in the area of six municipalities: Sosnowica, Hańsk, Urszulin, Stary Brus, Wierzbica and Ludwin. The data used in this paper, were obtained on the basis of the surveys conducted in these municipalities in 2016 by the Department of Environmental Engineering and Geodesy of the University of Life Sciences in Lublin. In the analyzed communes, there was a very large disproportion between the usage of sewerage and the water supply network. It has been shown that 79.1% of the inhabitants living in the afore-mentioned communes used the water supply network and only 22.5% of them used sewerage. In the discussed communities there are 9 collective, mechanical and biological wastewater treatment plants with a capacity of over 5 m³•d^-1. On the farms located in the scattered areas, which are not connected to the sewerage, wastewater is discharged mainly to the septic tanks. In four out of the six analyzed municipalities, there were 2345 septic tanks registered. Domestic sewage from some farms is purified in household wastewater treatment plants (395 pieces). The plants with the drainage systems are prevalent (84.9%), which may contribute to the groundwater quality degradation. In order to protect the natural environment within the communes that form the PNP, it is necessary to undertake the actions that will contribute to the improvement of the current state of water and wastewater management. While solving the existing problems related to water supply and wastewater treatment, it is strongly required to adhere to the principle of sustainable development and use highly effective systems in order to ensure that the ecological effects are appropriate.

Opis:: The aim of this paper is to present the current state of water and sewage management in the communes where the Roztocze National Park (RNP) is located. The park is located in Lubelskie voivodship, in the territory of four communes: Zamość, Zwierzyniec, Adamów and Józefów, while its buffer zone is located in the communes of Krasnobród, Tereszpol and Szczebrzeszyn. The paper uses data from surveys conducted in these municipalities in 2016. On average, 68.9% of the population used the water supply system in the municipalities surveyed, while 33.4% of the inhabitants had the possibility of discharging sewage to the sewerage system. In the area of the communes, there are 10 collective, mechanical and biological wastewater treatment plants with a capacity exceeding 5 m³·d^-1. The households which are not connected to the sewage network discharge wastewater mainly to non-return tanks. Four out of the seven surveyed communities had 64 domestic sewage treatment plants, including 60 systems with infiltration drainage, which do not ensure high efficiency of removing pollution and may even contribute to the degradation of groundwater quality. In order to solve the existing problems in the area of sewage and water management occurring in the communes where the Roztocze National Park is located, it is necessary to further develop collective sewage systems and equip the areas with dispersed buildings with highly efficient, residential sewage treatment plants, e.g. constructed wetlands.

Opis:: The aim of this paper is to present the current state and the need for development of sanitary infrastructure in the communes of Parczew District, in Lublin Voivodeship. Parczew District encompasses seven communes: Parczew, Dębowa Kłoda, Jabłoń, Milanów, Podedwórze, Siemień, and Sosnowica. The present paper uses the data from the surveys conducted in these communes in 2016. On average, 88% of the population used the water supply system in the communes surveyed, while 48% of the inhabitants were connected to a sewerage system. Parczew District had 12 collective mechanical and biological wastewater treatment plants with a capacity exceeding 5 m³/d. The households which were not connected to the sewerage network discharged the wastewater mainly to non-return tanks. In the communes surveyed, 1,115 households had domestic wastewater treatment plants. All of them were systems with infiltration drainage, which do not ensure high efficiency of removing pollutions and may even contribute to the degradation of the groundwater quality. In order to solve the existing problems of sewage and water management in the communes of Parczew District, it is necessary to further develop the collective sewerage systems and equip the areas which have a dispersed development layout with highly efficient domestic treatment plants, such as constructed wetlands.

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.

Opis:: Model investigations of wastewater purification were carried out in a medium sand bed with an assisting natural clinoptilolite layer 0.10 or 0.25 m thick. The effectiveness of wastewater purification related to basic qualitative parameters was in accordance with the Polish standards on sewage disposal into grounds and surface water. Medium sand soil bed with the assisting natural clinoptilolite layer 0.25 m thick showed on average the removal efficiency regarding TSS higher by 3.3%, total nitrogen by 29.3%, total phosphorus by 25.9%, reduction efficiency regarding BOD₅ by 1.1% and COD by 15.9% than that with the thinner clinoptilolite layer. The investigations confirmed that natural clinoptilolite with the granulation 1-5 mm can be used to enhance the removal of nitrogen and phosphorus compounds from wastewater with the application of infiltration drainage. However, very good effect of the TSS removal from the wastewater in the investigated soil beds can lead to their fast clogging under the infiltration drainage. Septic tanks should be designed in such a way that they retain as much TSS as possible, e.g., multi-chamber tanks instead of one-chamber ones.

Opis:: Septic tanks are common devices for primary wastewater treatment, however, they are prone to periodically raised effluent solids concentration, which can accelerate the clogging process in specific conditions. The aim of the study was to identify the impact of the secondary filter on the reduction of TS load and possibility to increase the operation time. The study was carried out in two series using six filters. In each series six filters (pipes with filtering material installed on the bottom) were used: three filters with filter mesh and the other three - with non-woven geo-textile. The filters were being filled with wastewater until clogging was achieved (wastewater table in pipes rising up to 50 cm). For the hydraulic conductivity estimation of falling water table tests were performed. Similar values of accumulated TS to dosed TS ratios were observed during the both series for the both filtering material types. The particle size distributions in the both filtering materials were similar. The fact of accumulation of particles of very small dimension (over 73% smaller than 5 μm), much smaller than the filtering material pores diameter might suggest that the process taking place was that of cake filtration. Despite the higher cumulated dry mass of filter cake and inside the filtering layer, the average hydraulic conductivity of non-woven geo-textile was higher than the average hydraulic conductivity of filter mesh. Probably thanks to the higher porosity of geo-textile higher amount of solids can be trapped inside the filtering material itself. The study showed the relatively low ratio of accumulated solids to supplied solids load; however, the accumulated mass seems to be significant for clogging prevention, especially in the case of several filtering layers usage. This way much more solids can be removed from the septic tank effluent (e.g., using four layers - about 10÷20%) and clogging process can be slowed down (two - three years longer operation time).
Osadniki gnilne to powszechnie stosowane urządzenia do wstępnego oczyszczania ścieków, jednak są one podatne na okresowe odprowadzanie zwiększonych stężeń zawiesin, co może w specyficznych warunkach przyspieszać procesy kolmatacji. Celem badań było określenie wpływu filtra wtórnego na zmniejszenie obciążenia zawiesiną i możliwość zwiększenia czasu eksploatacji. Badania przeprowadzono w dwóch seriach przy użyciu sześciu filtrów. W każdej serii użyto sześciu filtrów (rury z materiałem filtrującym zainstalowanym na dnie): trzy filtry z filtrem siatkowym, a pozostałe trzy - z geowłókniny. Filtry były zapełniane ściekami aż do uzyskania kolmatacji (zwierciadło ścieków w rurach sięgało do 50 cm). Dla oszacowania przewodności hydraulicznej opadającego zwierciadła wody zostały przeprowadzone testy. Zaobserwowano podobne wartości zawiesin zgromadzonych proporcjonalnie do dozowanych podczas obu serii oraz dla obu typów materiałów filtrujących. Rozkład wielkości cząstek w obu materiałach filtracyjnych był podobny. Fakt zgromadzenia cząstek o bardzo małych wymiarach (ponad 73% poniżej 5 μm), znacznie mniejszych niż średnica porów materiału filtracyjnego, może sugerować, że odbywający się proces dotyczy placka filtracyjnego. Pomimo wyższej skumulowanej suchej masy placka filtracyjnego i tej wewnątrz warstwy filtracyjnej, średnie przewodnictwo hydrauliczne geowłókniny było wyższe niż średnie przewodnictwo hydrauliczne filtra siatkowego. Prawdopodobnie dzięki wyższej porowatości geowłókniny większa ilość zawiesin możne zostać zatrzymana wewnątrz samego materiału filtrującego. Badania wykazały stosunkowo niski współczynnik nagromadzonych cząstek stałych do dostarczonych; jednak skumulowana masa wydaje się istotna dla zapobiegania kolmatacji, zwłaszcza w przypadku wykorzystania kilku warstw filtrujących. W ten sposób o wiele więcej zawiesin można usunąć z odpływu z osadników gnilnych (na przykład dla czterech warstw - około 10÷20%) i proces kolmatacji może zostać spowolniony (dwa-trzy lata dłuższy okres użytkowania).

Opis:: The aim of the study was to determine the filter cake permeability. The research was carried out on the excessive sludge flushed out from a septic tank. Two types of laboratory filters: filled with fine sand and made of geotextiles were used. The permeability of the filter cake was inversely correlated linearly to the accumulated organic solids. Based on applied organic solids, the related filter cake permeability time of filter failure can be predicted. The shortest failure time, not exceeding two years, may be recorded when filter cake development and clogging processes simultaneously take place in small-pore diameter filters and when the concentration of volatile solids is high.
