Opis:
Water is not a commercial product as any other, but rather a good that has to be protected, defended and treated as a legacy. (European Parliament Directive 2000/60/EC). The best method for protection of groundwater is its efficient using and purified sewage amount increasing. Therefore, it is important to build the construction and modernization of wastewater treatment plants. The water law defines the criteria of cleaned sewages which flow into water and ground. Augustow is located in the northern part of the Podlasie province on borders of The Augustow Forest, on the river Rospuda-Netta [3]. The river is the receiver set of cleaned sewage from local sewage treatment plants. Rospuda-Netta river central section runs through the area of the special protection of birds PLC 200002, and the outcome section – through the area of The Biebrzanski National Park and simultaneously through the area of PLC 200001 entering in part of NATURE 2000. This is the reason of special wastewater purification. The aim of the study was checking, whether the sewage treatment plant supporting Augustow and nearest communes supply into the receiver (Netta river) enough cleaned sewage and whether parameters of cleaned wastewater are within in an allowed range through statement of environmental impact.
Woda nie jest produktem komercyjnym, takim jak każdy inny, lecz raczej dobrem, które musi być chronione, bronione i traktowane jak dziedzictwo. (Parlament Europejski i Rady Unii Europejskiej: "Ustanowienie ram dla działalności Wspólnoty w dziedzinie polityki wodnej", Dyrektywa 2000/60/EC) Najlepszą metodą służącą do ochrony wód jest jej oszczędne używanie oraz zwiększenie ilości poprzez oczyszczanie ścieków, czy innego rodzaju zanieczyszczonych wód powierzchniowych. Z tego względu tak ważna jest budowa i rozbudowa oczyszczalni ścieków. Kryteria, jakim muszą odpowiadać ścieki oczyszczone, które odprowadzane są do wód i ziemi, określa prawo wodne. Augustów położony jest w północnej części województwa podlaskiego na obrzeżach Puszczy Augustowskiej, nad rzeką Nettą, będącą jednocześnie odbiornikiem ścieków oczyszczonych lokalnej oczyszczalni. Środkowy odcinek Rospudy-Netty przebiega przez obszar specjalnej ochrony ptaków PLC 200002 "Puszcza Augustowska", a odcinek ujściowy - przez obszar Biebrzańskiego Parku Narodowego i jednocześnie obszar PLC 200001 "Dolina Biebrzy", wchodzące w skład Europejskiej Sieci Ekologicznej NATURA 2000. Celem prowadzonych prac badawczych było zatem sprawdzenie, czy oczyszczalnia ścieków Augustów obsługująca teren miasta i gminy wprowadza do odbiornika ścieków (rzeki Netty) ścieki wystarczająco oczyszczone i czy uzyskane parametry ścieków oczyszczonych mieszczą się w zakresie dopuszczonym przez operat wodno-prawny.

Opis:
Filtration is one of the basic and commonly used process of water treatment filtration process. The development of knowledge about this process has its roots at the turn of the thirties and forties of the last century. To this day, there are still conducted research in the field of filtration by many scientists around the world. Currently, the design of water treatment filters is based on a set of guidelines. Therefore, studies on the clogging of the filtration process, seem to be important, as they affect the more rational filter design. The aim of this work was to investigate the kinetics of the clogging of the filtration process for the selected sand bed. Carried out experiments consisted in filtration of the prepared water with variable speeds: 10, 15, 20, 25, 30, 35 m/h. Based on the observations, it was found that the efficiency of impurities removing is directly related to the rate of filtration and the amount of filtered water. With the increase of the filtered water volume of through the bed, there was a decrease in the efficiency of color and turbidity removing in the upper filter layers in the depth range of 0-43 cm. The decrease in the efficiency of purification in these layers resulted in efficiency of removing color and turbidity. It follows that the smaller the granulation of the bed in the upper layer, the faster the clogging and the shorter filtration cycle time.
Jednym z podstawowych i powszechnie stosowanych procesów uzdatniania wody jest proces filtracji. Rozwój wiedzy na temat tego procesu ma swoje korzenie na przełomie lat trzydziestych oraz czterdziestych ubiegłego wieku. Do dnia dzisiejszego prowadzone są wciąż badania w zakresie filtracji przez wielu naukowców na całym świcie. Obecnie projektowanie filtrów do uzdatniania wody odbywa się na podstawie niezmiennego zbioru wytycznych. W związku z tym zasadne wydają się badania nad kolmatacją procesu filtracji, gdyż mają one wpływ na bardziej racjonalne projektowanie filtrów. Celem niniejszej pracy było zbadanie kinetyki kolmatacji procesu filtracji wybranego złoża piaskowego. Realizowane eksperymenty polegały na filtracji przygotowanej wody ze zmiennymi prędkościami: 10, 15, 20, 25, 30, 35 m/h. Na podstawie przeprowadzonych obserwacji stwierdzono, iż efektywność usuwania zanieczyszczeń jest bezpośrednio związana z szybkością filtracji i ilością przefiltrowanej wody. Wraz ze wzrostem objętości przefiltrowanej wody przez złoże odnotowano spadek efektywności usuwania barwy oraz mętności w wierzchnich warstwach filtracyjnych w zakresie głębokości 0-43 cm. Spadek efektywności oczyszczania w tych warstwach miał wpływ na obniżenie ogólnej efektywności usuwania barwy oraz mętności. Wynika z tego, iż im mniejsza granulacja złoża w górnej warstwie, tym szybsza kolmatacja i krótszy czas cyklu filtracyjnego.

Opis:
One of inorganic sorbents used in water treatment technology is activated alumina. It is recommended by the European Commission to remove inorganic impurities, such as arsenic, fluoride, selenium and silicates. The adsorbent is usually applied in a granular form, under flow conditions. It can become absorbent material, increasingly used due to the presence of arsenic beside iron and manganese in groundwater intakes. The aim of the study was to evaluate the effectiveness of groundwater treatment in the technological system containing adsorption on activated alumina. The experiment was performed on test model CE 581 manufactured by G.U.N.T. Hamburg, in which four treatment stages can be extracted. The first stage is used in a gravel filter of grain size 1–2 mm, in the second sand filter of grain size 0.4–0.8 mm. The third and fourth phase includes two adsorbers. The first adsorber comprises activated alumina (Al,sub>2O3) and the other comprises a granular activated carbon. The study was conducted at different speeds of filtration: 5, 10 and 15 m/h. In the raw water samples and the purified water samples after each treatment step the following parameters were determined: pH, O,sub>2 concentration, electrolytic conductivity, SO42-, concentration, NO3- concentration, PO43- concentration, Cl- concentration, color, turbidity, iron and manganese concentration, CODMn, total hardness, calcium hardness, magnesium hardness, content of dissolved substances. The conducted research indicates that optimum filtration rate for most pollution is 15 m/h. Moreover, the presence of activated alumina has contributed to increasing the efficiency of nitrate (V) and phosphate (V) ions removal.

Opis:
The beginning of the period where the impact of human activity took dangerous size is considered to be 40 years of the nineteenth century. Then the large-scale production of electricity increased production of metallurgical industry and transport development. Significant changes contributed to rapid population growth and urbanization and industrialization processes. Man by intensive exploitation reduces or completely exhausted most natural resources. This has resulted in the availability criterion, which is distinguished by inexhaustible and exhaustible resources. Exhaustible resources may include solar, wind, energy, ocean currents and the energy of the Earth. Exhaustible resources, however, are the elements of nature that as a result of the operation can be completely depleted or destroyed. These resources include: water, soil, plant world, animal world natural resources. The greater the intensity of acquiring human resources, the faster will be the depleted. There is also a very important division of exhaustible resources: non-renewable resources, renewable and very difficult reproducible (living areas). Non-renewable resources are mainly minerals, such as iron ore, crude oil, coal, sulfur, natural gas, useful stones, limestone, salt, and many other minerals). After extraction resources are processed, and the bed from which they were extracted can no longer be used. It is different from renewable resources; they are characterized by the fact that over time they are reconstituted, although, for this to happen balance of the environment through the rational use must be maintained. These resources include, among others, soil, water, flora and fauna, as well as atmospheric air.

The objective of this work was to verify the granular activated alumina (AA) sorption properties, during the process of removing copper, lead and cadmium from water, and to monitor the impact of magnetic field (MF) on the effectiveness of removing copper, lead and cadmium from water. Activated alumina adsorption is known to be an effective and inexpensive technology for the removal of selenium and arsenic from water, and was suggested by EPA as a BAT for point-of-use applications. The removal of copper, lead and cadmium from water using AA and impact of magnetic field was reported to a lesser extent. Pilot tests showed that the use of AA sorption materials with MF impact could possibly decrease the copper, lead and cadmium content in the model water. The MF also had a positive effect on the efficiency of removal copper, lead and cadmium on AA. Increasing the efficiency of heavy metals removal in the samples exposed to magnetic field varied from 1.9% to 8.2% compared to the control samples.

One of the most important technological processes of water treatment is the process of filtration. Scientists and producers keep on searching new filtration materials which allow for better water purification, are simple in exploitation and do not add chemical substances to the treated water. Therefore, the aim of the present study was to analyze physical and chemical parameters of two unknown porous masses X1 and X2. Such physical parameters as color, granulation, bulk density, the equivalent diameter, the coefficient of uniformity and the porosity of the material were measured and determined. Additionally, the possibility of water treatment was studied during the filtration process in the laboratory tests. Chemical parameters were examined in the water flowing through the mass, such as pH, conductivity and COD-Mn as a general indicator of the content of organic substances in the water. Both studied porous masses were characterized by uniform size of particles. But they were not efficient enough in satisfactory reduction of oxygen consumption. Mass X2 slightly better adsorbed organic substances. It was found that the tested unknown mass filter slightly increase the pH of the filtered water.

Opis:
The amount of water required to support a river ecosystem in proper condition are of particular importance in the areas of high natural value. The hydrological threats for the protected areas are region-specific and vary from region to region. The local hydrological conditions depend largely on the temporal and spatial variations of the hydrologic cycle, of the main components and physiographic conditions on site. Future climate change is projected to have a significant impact on the hydrological regime, water resources and their quality in many parts of the world. The water-dependent ecosystems are exposed to the risk of climate change through altered precipitation and evaporation. Investigating the current climate changes and their hydrological consequences are very important for hydrological issues. This analysis may be a very important foundation for determining the causes observed in the recent period of anomalous growth – both hydrological and climatic. The aim of the research is to assess the effect of projected climate change on water resources in lowland catchment the Narew River in Poland. The hydrological reaction to climate warming and wetter conditions includes changes in flow and water level. This paper describes the directions of changes climatic and hydrological conditions and the impact of climate change on the Narew River. The data such as: daily air temperature, precipitation obtained from the Bialystok climate station located within the Narew river and hydrological data such as water flows and water states observed in water gauges were used for the analysis of climate variability and their hydrological consequences. The results show a significant decrease in winter outflows in river, as well as a delayed increase in the spring melt flow. It has also been observed that this is the initial phase of changes in maximum water levels and maximum flows.

Opis:
Rising demands concerning water treatment and conservation make it necessary to search for more effective as well as cheap and ecologically safe solutions. During the filtration process quartz sand is replaced by filter materials which also have a strong effect on account of reactions taking place on a bed’s surface. Today’s technologies for groundwater and seepage water treatment in rapid filters make use of oxidation beds. They are able to effectively remove manganese (II) and iron (II) compounds based on heterogeneous oxidation catalysis. The main catalyst of the manganese removal process in terms of its catalytic oxidation in filtration beds is manganese dioxide. This compound is used as an oxidizing agent in many processes. The research conducted as part of this paper was aimed at creating a product with the qualities similar to a popular Greensand bed protected by patent. The authors tested washed quartz sand varying in granulation which was subject to activation in 10% KMnO4 solution. Grains of quartz sand after covering them with a permanent coat of manganese oxide developed the superficial oxidation layer. While performing the tests, a temperature of the process served as a variable. The beds produced as a result of the experiment enable the removal of iron and manganese from water without prior alkylation. Furthermore, they are an effective method of purifying water of organic pollutants and ammoniacal nitrogen. They function as oxidizing and filtering masses.

The Dojlidy Ponds, which include Dojlidy water dam, are located within Bialystok city limits in Podlasie area, Poland. The reservoir with a water surface of 34 ha and average depth of 1.75 m was constructed in 1962 as a result of Biala River damming. The researches were conducted in July, October and December 2014 as well as in March 2015. Each time five test samples were collected from spots located along the reservoir. Water samples were tested for the presence of ammonia nitrogen, nitrite nitrogen, organic nitrogen, phosphates and organic phosphorus. The values of nutrient indicators exhibited high variability during the study period. The highest concentration of nitrite and nitrate nitrogen were observed in July, while the lowest in October – nitrite nitrogen, and in December – nitrate nitrogen. Different situation was observed after the analysis of phosphorus forms – the highest concentrations of organic phosphorus and phosphates were observed in December and the lowest in July. Relatively high concentrations of nitrogen and phosphorus forms identified in water samples were most likely caused by tributaries, due to the pollution from the reservoir catchment. Technical parameters of the object and location of the reservoir have undoubtedly an impact on the tested parameters contents.

Opis:
The availability of water in adequate sufficient quantity and quality is the most important factor in maintenance of life and human activity. Surface water as easily accessible resources per citizen in Poland should not be compared to other countries of the European Union. Podlasie is a lowland region, which is dominated by vast plains occasionally varied by low hills with gentle slopes. Natural lakes occurring sparsely are heavily overgrown or completely restated as a result of moor succession. The storage of natural hollows which store water resulted in the construction of artificial dam reservoirs, allocated primarily to water accumulation. Lowland development of small retention mainly consists of increasing the retention capacity and prevention of drought and floods, while maintaining and supporting the development of the natural landscape. This article presents the characteristics of selected major small water reservoirs in Podlasie. Characterized and evaluated the susceptibility of dam reservoirs degradation: Czapielówka, Korycin, Otapy-Kiersnówek, Repczyce, Zarzeczany. To evaluate the susceptibility of degradation there was applied Schindler factor, which is the ratio of the accumulated surface water reservoir and its catchment area to the volume of the reservoir. In addition, the influence of development of catchment management and the degree of degradation has been evaluated. Realising aware of the limitations of the size of the water resources is suggested to take appropriate action to alleviate the degradation of artificial reservoirs.

Obecnie na skutek intensywnej działalności antropogenicznej wody powierzchniowe i podziemne zagrożone są poważnym skażeniem związkami boru. Większość stacji uzdatniania nie projektuje specjalnych technologii tylko do jego usuwania. W związku z tym celem prowadzonych prac badawczych była analiza efektywności usuwania boru z wód podziemnych za pomocą takich metod uzdatniania, które są wykorzystywane na typowych stacjach. W pracy porównano skuteczność filtracji na wybranych masach różniących się składem i właściwościami takich jak: węgiel aktywny, piasek kwarcowy, złoże mieszane zeolitowe oraz piroluzyt. Sprawdzono też korelacje pomiędzy innymi zanieczyszczeniami wody a borem. Przeprowadzone w trzech seriach badania pokazały, iż można skutecznie usuwać bor z wody prawidłowo wykonanych płukaniach związkami o charakterze alkalicznym a następnie wodą. W przeciwnym przypadku w kolejnych seriach filtracyjnych następuje wtórne uwalnianie boru oraz znaczny spadek efektu oczyszczania.

The article presents results of application of various technologies of the process of vermicomposting of waste biomass of sugar beet pulps using earthworms E. fetida. A possibility of using E. fetida for quick utilization of sugar beet pulp in vermireactors with different characteristics of initial bed-dings was observed. The obtained vermicomposts were characterised by higher N, P, K, Ca and Mg content compared to the initial waste biomass. During waste utilization in vermireactors (BAGS and SGS) it was noted that the population of earthworms persisted, but earthworm count insignificantly decreased. Significant differences in the mean biomass of specimens from BAGS and SGS groups were also observed. The greatest differences (22 and 21%, p < 0.05) were observed on the 10th and 40th day of the experiment. Earthworms multiplied that has been proved by the mean number of laid cocoons which was significantly increasing during the experiment conducted using both technologies (on average by 36%; p < 0.05). Significant differences in the mean cocoon weight between the used technologies were noted only on the 10th day of the experiment.
W artykule przedstawiono wyniki zastosowania różnych technologii procesu wermikompostowania odpadowej biomasy wysłodków buraczanych przy użyciu dżdżownic E. fetida. Stwierdzono możliwość wykorzystania E. fetida do szybkiego unieszkodliwiania wysłodków w wermireaktorach o odmiennej charakterystyce podłoży startowych. Otrzymane wermikomposty charakteryzowały się wyższą zawartością N, P, K, Ca i Mg w porównaniu z inicjalną biomasą odpadową. Podczas unieszkodliwiania odpadu w wermireaktorach (BAGS i SGS) stwierdzano utrzymywanie się populacji dżdżownic przy nieistotnych spadkach ich liczebności. Zaobserwowano istotne różnice w średniej biomasie osobników z grup BAGS i SGS. Największe różnice (22 i 21%, p < 0.05) zaobserwowano w 10 i 40 dniu doświadczenia. Dżdżownice rozmnażały się, o czym świadczy średnia liczba składanych kokonów, która rosła istotnie w trakcie trwania doświadczenia w obu technologiach (średnio 36%; p < 0,05). Istotne różnice w średniej masie kokonów w zastosowanych technologiach stwierdzono jedynie w 10 dniu doświadczenia.
