Opis:
In this study, the current operation efficiency of the wastewater treatment plant (WWTP) in the city of Kłodzko in the Lower Silesia Voivodeship (Poland) was analyzed and the predicted amount of the wastewater flowing to the WWTP in a 20-year period (until the year 2036) was estimated. The data on the quality and the quantity of raw (entering to the WWTP) and treated sewage from the years 2012-2016 were analyzed. The five essential pollutants indicators: biochemical oxygen demand (BOD5), chemical oxygen demand (CODCr), total suspended solids (TSS), total nitrogen and total phosphorus, regulated in the water permit were used to evaluate the efficiency of contaminants removal. On the basis of the percentage reduction of the individual pollutants indicators and their acceptable concentrations in the treated sewage, the effectiveness of the operation of the object was determined. Furthermore, a so-called the treatment plant reliability factor (RF) was calculated and its value below 1.0 indicates the correct operation of the wastewater treatment plant. After determining the prospective amount of raw sewage in 2036 (based on the decreasing population in the city) it has been found that the WWTP will work with a significant reserve of capacity and the modernization of the treatment system, leading to a decrease of its capacity should be considered.

Opis:
W pracy przedstawiono wyniki oczyszczania strumienia ścieków włókienniczych o wysokim stężeniu zanieczyszczeń za pomocą koagulacji. Na podstawie wskaźników charakteryzujących oczyszczone w skali laboratoryjnej ścieki (pH, indeksu osadu, temperatury, stężenia chlorków, ChZT, BZT) oceniono efektywność działania badanych koagulantów i flokulantów. Wybrano najlepszą parę środków. Efekty oczyszczania potwierdzono w skali przemysłowej. Udało się osiągnąć parametry oczyszczonych ścieków pozwalające na zrzut do miejskiej sieci kanalizacyjnej.
The paper presents the results of "high-loaded" wastewater stream coagulation-flocculation treatment. On the basic of indicators that characterized treatedin labolatory scale wastewater (pH, sludge index, temperature, chlorides, COD and BOD) the effectiveness of tasted coagulants and flocculants was assessed. The best coagulant-flocculant pair was chosen. Treatment effects were confirmed on an industrial scale. Limiting emission factors were achieved so dumping into municipal sewer was possible.

Opis:
Celem przeprowadzonych badań było uzyskanie wiedzy, jak umiejscowienie oczyszczalni względem zlewni kanalizacyjnej wpływa na temperaturę dopływających do niej ścieków. Analizą objęto cztery systemy kanalizacyjne, różniące się długością kolektora tranzytowego pomiędzy oczyszczalnią a zabudowaniami mieszkalnymi, w których wytwarzane były ścieki bytowe. W badanych systemach kanalizacyjnych ścieki odprowadzane były do oczyszczalni o przepustowości hydraulicznej od 100 do 300 m3·d-1, charakteryzujących się liczbą RLM nie większą niż 2000. Pomiary temperatury ścieków odpływających z kanalizacji oraz powietrza atmosferycznego, w analizowanym roku 2012, prowadzono w sposób ciągły, z interwałem 1 godzinnym, za pomocą czujników rezystancyjnych połączonych z rejestratorami danych. Przeprowadzone badania wykazały, że odległość oczyszczalni od zlewni kanalizacyjnej wywiera istotny wpływ na temperaturę ścieków odpływających z sieci kanalizacyjnej. W okresie zimowym średnia dobowa temperatura ścieków odpływających z kolektorów tranzytowych o długości od 300 do 600 m była niższa nawet o blisko 3ºC, natomiast w okresie letnim aż o 8ºC, w porównaniu do kolektorów tranzytowych o długości nieprzekraczającej 10 m. Wykazano ponadto, że na temperaturę ścieków dopływających do oczyszczalni, oprócz długości kolektora tranzytowego, istotnie wpływa także natężenie przepływu ścieków. Przy wzroście natężenia odpływu ścieków z kanalizacji o 100%, ich temperatura może wzrosnąć w okresie zimowym o 1ºC, natomiast w letnim o 3ºC. W przypadku sieci kanalizacyjnych zakończonych długimi kolektorami tranzytowymi, niekorzystnemu skróceniu ulega czas trwania temperatury ścieków optymalnej w aspekcie usuwania związków biogennych, a przy tym jednocześnie wydłuża się czas trwania temperatury ścieków niekorzystnej dla ich biologicznego oczyszczania.
The aim of the research was to get the expertise, how location of wastewater treatment plant to basin of sewage system influences the temperature of inflowing wastewater. The analysis included four sewage systems, which are different for the sake of length of transit canal between treatment plant and residential buildings, in which domestic sewage was produced. In analysed systems sewage flew into the treatment plants with hydraulic capacity range from 100 to 300 m3·d-1, and with population equivalent less than 2000. Measurements of temperature of air and wastewater outflowing from sewage system, in analysed year 2012, were conducted continuously, with 1 hour interval, with use resistance sensors connected with data recorder. The research showed, that the distance of treatment plant to basin of sewage system has a significant impact on wastewater temperature outflowing from sewage system. In winter period mean daily wastewater temperature outflowing from transit manifolds with length from 300 to 600 m was lower even about 3ºC, but in summer period up to 8ºC, in comparison to transit manifolds with length less than 10 m. Moreover, it was proved that, apart from length of transit manifold, also intensity of wastewater flow has a significant impact on wastewater temperature flowing into the treatment plant. With increase of intensity of wastewater flow about 100%, its temperature can increase in winter period about 1ºC, and about 3ºC in summer period. In case of sewage systems ended with long transit manifold, the duration time of optimal sewage temperature in terms of biogenic compounds removal is unfavourable reduced, and at the same time the duration time of wastewater temperature unfavourable for its biological treatment is extended.

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.

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 Bialski District located in the Lublin Voivodeship. The Bialski District encompasses 2 urban communes: Miedzyrzec Podlaski and Terespol and 17 rural communes: Biała Podlaska, Drelów, Janów Podlaski, Kodeń, Konstantynów, Leśna Podlaska, Łomazy, Międzyrzec Podlaski, Piszcząc, Rokitno, Rossosz, Sławatycze, Sosnówka, Terespol, Tuczna, Wisznice and Zalesie. The present paper uses the data from the surveys conducted in these communes in 2016. On average, 79.2% of the population used the water supply system in the surveyed communes, while 39.4% of the inhabitants had the possibility of discharging wastewater to the sewerage system. In the area of the communes, there were 20 collective, mechanical and biological wastewater treatment plants with a capacity exceeding 5 m3/d. The households which were not connected to the wastewater network, discharged wastewater mainly to non-return tanks. In the surveyed communes, there were 4437 household wastewater treatment plants. Most of them (above 80%) were the systems with infiltration drainage, which do not ensure high efficiency of pollutants removal and may even contribute to the degradation of the groundwater quality. In order to solve the existing problems of wastewater and water management occurring in the communes where the Bialski District is located, it is necessary to further develop collective wastewater systems and equip the areas characterized by dispersed housing with highly efficient household treatment plants, e.g. constructed wetlands.

Opis:
The most of the on site wastewater treatment systems in Poland discharges treated effluent to the soil. The goal of phosphorus (P) reduction from dispersed sources of pollution can be achieved by application of P reactive materials in the construction of wastewater infiltration systems. Two P reactive materials were tested in this study: Polonite® in grains of 2÷6 mm and lightweight aggregate Leca® in grains of 4÷10 mm. Apparent P sorption capacity was assesed on 40.9 mg·g-1 (Polonite®) and 5.1 mg·g-1 (Leca®). Both materials sorbed P-PO4 very fast, after 15 min over 90% of P was removed from solution and wastwater. Wastewater used in this study came from the outlet from the septic tank of on site septic system. P-PO4 solution was prepared from KH2 PO4 and the tap water. In the small column experiment, four collumns (2 filled with Polonite® and 2 filled with Leca®) were fed with wastewater and P-PO4 solution in hydraulic loadings of 30÷40 dm3 ·m-2·d-1. All the columns removed significant amounts of P from both solution and wastewater with the reduction between 28.3% and 72.5%. The mean P-PO4 effluent concentrations ranged from 1.21 mg·dm-3 to 7.12 mg·dm-3. The best overall performance was achieved by the Polonite® fed with solution. Both tested materials can support wastewater treatment in on site systems.

Opis:
The scope of this study was to apply the Biolog system to identify and characterize a Serratia strain isolated from the surface of black plastic pieces which constitute the fluidized bed filter (onsite wastewater technology, OSWT). The preliminary isolation of the strain was done in the medium with tetracycline at a 16 mg/l concentration. To characterize the isolated strain, the following Biolog methods were applied: (1) EcoPlates microplates for evaluation of physiological profiling, (2) GEN III OmniLog® ID System for identification of the isolate, and (3) phenotypic microarrays (PM) technology for evaluation of sensitivity to antibiotics (PM11 and PM12). Results were recorded using the original OmniLog® software. The Serratia strain was identified as Serratia marcescens ss marcescens with similarity index 0.569. The same identification was obtained by the 16S rDNA analysis. PM analysis showed an enhancement of phenotype (resistance or growth) of this strain to 35 antibiotics. The loss of phenotype (sensitivity or non-growth) was observed only for 5 antibiotics: lomefloxacin (0.4 µg/ml), enoxacin (0.9 µg/ml), nalidixic acid (18.0 µg/ml), paromomycin (25.0 µg/ml) and novobiocin (1100 µg/ml). This study acknowledges that the methods proposed by the Biolog system allow correct and complete identification and characterization of the microbes isolated from different environments. Phenotypic microarrays could be successfully used as a new tool for identification of the multi-antibiotic resistance of bacteria and for determination of the minimal inhibition concentrations (MIC).

Opis:
Celem badań prezentowanych w pracy było rozpoznanie zmian efektywności oczyszczania ścieków bytowych w oczyszczalniach gruntowo-roślinnych i glebowo-roślinnych w zależności od czasu i warunków ich eksploatacji. W pracy przedstawiono wyniki badań skuteczności oczyszczania ścieków w złożach gruntowo-trzcinowych, zbudowanych wg systemu Kickutha, oraz oczyszczalni glebowo-roślinnej w początkowym okresie eksploatacji (na 4 obiektach) i po 15 latach (na 2 obiektach). Zaskakujące były zdecydowanie różniące się wyniki, uzyskane w pierwszych latach eksploatacji, z dwóch podobnych złóż gruntowo-trzcinowych, których eksploatację rozpoczęto w tym samym roku. Na jednym skuteczność oczyszczania zwiększała się z upływem czasu, a na drugim wystąpiły objawy braku tlenu w złożu i słabej nitryfikacji azotu, co przejawiało się dużym stężeniem N-NH4 w odpływach z oczyszczalni. Przyczyną tego była błędna lokalizacja oczyszczalni - w miejscu silnie zacienionym, co wpłynęło na bardzo słaby rozwój trzciny i jej systemu korzeniowego, a tym samym na słabe napowietrzanie złoża. Z upływem lat eksploatacji pogarszała się przepuszczalność złóż dwóch badanych oczyszczalni gruntowo-trzcinowych i wystąpiło ich zakolmatowanie, powodowane głównie niedostatecznym oczyszczaniem wstępnym doprowadzanych ścieków. Stwierdzono znacznie wyższy stopień oczyszczania ścieków w oczyszczalni glebowo-roślinnej, zarówno w początkowym okresie eksploatacji, jak i po 15 latach. Uzyskane zmniejszenie głównych wskaźników zanieczyszczenia po 15 latach eksploatacji gruntowo-trzcinowych było następujące (w %): Nog - 47, Pog - 63, BZT5 - 93, ChZTCr - 81, natomiast na oczyszczalni glebowo-roślinnej: Nog - 84, Pog - 99, BZT5 - 95, ChZTCr - 74.
The aim of this study was to trace changes in the efficiency of domestic sewage treatment in soilplant and ground-plant systems in relation to the time and conditions of use. The paper presents results of testing the effectiveness of sewage treatment in ground reed beds constructed according to Kickuth system and in soil-plant treatment units, in the beginning of utilization period (in 4 objects) and after 15 years (in 2 objects). Surprising were the definitely different results obtained during the first years of utilization in two similar reed beds, which started operating in the same year. In one, the efficiency of treatment increased with time and in the other the symptoms of oxygen deficit and weak nitrification were observed in the bed which manifested itself in high N-NH4 concentrations in the outflow from the treatment unit. The reason was in faulty location of the treatment unit in an intensely shaded place resulting in poor development of reed and its root-rhizome system and, consequently, in poor aeration of the bed. In the two examined ground reed treatment units, the beds lost their permeability and became silted with time due mainly to insufficient primary sewage treatment. The soil-plant treatment unit showed considerably higher degree of sewage purification, both during the initial period of utilization and after 15 years. In ground reed beds, after 15 years of their utilization, the reduction of main pollutants was (in %): Ntot - 47, P - 63, BOD - 93, CODCr - 81, whereas in soil-plant treatment units it was: Ntot - 84, P - 99, BOD - 95, CODCr - 74.

Opis:
The paper describes the status of water supply and sanitation infrastructure in the Kraśnik County. The description is based on the official statistical data and the data obtained in a survey carried out in 2016. The Kraśnik County is located in the Lublin Province and comprises 10 communes: one urban commune (the Municipality of Kraśnik), two urban-rural communes (Annopol and Urzędów), and seven rural communes (Dzierzkowice, Gościeradów, Kraśnik, Szastarka, Trzydnik Duży, Wilkołaz, and Zakrzówek). In 2016, an average of 90.9% of the County’s inhabitants had the access to the mains water, but only 13.5% were connected to the mains sewerage. The County has six centralized wastewater treatment plants with a total capacity of approximately 14.164 m3/d. The survey data showed that the records of cesspools were kept in only four of the County’s communes: the Municipality of Kraśnik, Urzędów, Wilkołaz, and Zakrzówek. The total number of cesspools in those communes was 4776. The Kraśnik County is in great demand for the construction of on-site domestic wastewater treatment plants, which are an excellent alternative to cesspools. The network of domestic wastewater treatment plants in the Kraśnik County is made up almost entirely of systems with a drainfield, which may pose a serious threat to the soil and water environment. The results of the present study suggest that Commune Offices must take decisive steps to eliminate the existing disproportion between the coverages of the sewerage and water supply systems in the County’s communes.

Opis:
Azo dye wastewater treatment is urgent necessary nowadays. Electrochemical technologies commonly enable more efficient degradation of recalcitrant organic contaminants than biological methods, but those rely greatly on the energy consumption. A novel process of biofilm coupled with electrolysis, i.e., bioelectrochemical system (BES), for methyl orange (MO) dye wastewater treatment was proposed and optimization of main influence factors was performed in this study. The results showed that BES had a positive effect on enhancement of color removal of MO wastewater and 81.9% of color removal efficiency was achieved at the optimum process parameters: applied voltage of 2.0 V, initial MO concentration of 20 mg/L, glucose loads of 0.5 g/L and pH of 8.0 when the hydraulic retention time (HRT) was maintained at 3 d, displaying an excellent color removal performance. Importantly, a wide range of effective pH, ranging from 6 to 9, was found, thus greatly favoring the practical application of BES described here. The absence of a peak at 463 nm showed that the azo bond of MO was almost completely cleaved after degradation in BES. From these results, the proposed method of biodegradation combined with electrochemical technique can be an effective technology for dye wastewater treatment and may hopefully be also applied for treatment of other recalcitrant compounds in water and wastewater

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 wastewater treatment plant is classified as a complex system due to its nonlinear dynamics, large uncertainty in the disturbance inputs, multiple time scales in the internal process dynamics and multivariable structure. Aeration is an important and expensive activity that is carried out during wastewater treatment plant operation. A precise aeration control in biological processes for all the operating conditions is necessary in order to guarantee adequate biological conditions for microorganisms. Therefore, the most important is to operate the biological processes so that a minimal energy was consumed and minimal DO concentration demand was applied. The paper proposes a two advanced control systems to track the dissolved oxygen reference trajectory. A decentralized and multivariable nonlinear predictive control algorithms are designed and compared. Simulation tests for the case study wastewater treatment plant are presented.

Opis:
The sewerage is an often skipped element of the wastewater treatment system. Because of its high retention capacity and relatively long flow time, it has to be considered that processes affecting wastewater composition and their vulnerability to biological treatment may occur in the sewerage. Changing hydraulic conditions in collectors and numerous side influents providing new portions of wastewater diversified in quantity and quality cause difficulties in a precise description of biochemical transformations occuring during wastewater flow in gravity sewers. The authors conducted research on changes in organic compounds (expressed as total COD) and their dissolved form (soluble COD) in wastewater, during their flow through the laboratory model of a gravity collector. The model is constructed as a cascade of five basins made from acrylic glass, 1.12 L each. Wastewater flowed through the model continuously with the rate of 0.5 L/h. It allowed to achieve the flow time of 11 hours, which is 2-3 times longer than flow times occuring in a typical large sewer network and enabled to take samples in the collector profile. Reaeration process, pH and temperature, as well as the psychro and mezophilic bacteria were also taken into account in the analysis. The results of two research series were presented in the article, i.e. where wastewater flowed continuously through the model for 17 and 33 days, respectively. It was proven that during flow in a collector, a number of processes takes place, including sedimentation, washing out of solid contaminations, removal of dissolved organic compounds and enzymatic hydrolysis of slowly biodegradable organic matter. Biomass growth in bulk wastewater and on the model wall proved that biological processes occur there. There are significant differences between research series, mainly caused by the temperature. It was observed that the amount of biofilm was rather small and did not exceed 5% of total biomass. Removal of total COD was in the range of 28.8-80.3 mg O2/(L h) and soluble COD from 8.5 to 11.5 mg O2/(L h). In the last part of the model, the rate od COD removal decreased due to the lack of substrate, which is in accordance with data given by other researchers.
