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, SO₄^2-, concentration, NO^3- concentration, PO₄^3- 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 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.

Opis:: The aim of the research was to assess the state of air pollution with mentioned pollution for the area of the city of Bialystok. The analysis was carried out using data from 2 air monitoring stations. The stations are owned by the Provincial Inspectorate for Environmental Protection in Bialystok. The work also compared the air quality in Bialystok with the air quality in the main voivodship cities with a similar population: Olsztyn, Lublin, Bydgoszcz and two of the largest urban agglomerations in the country: Warsaw and Wroclaw. It was found that the quality of air in the city of Bialystok compared to the analyzed cities is the best. In addition, it was observed that increased concentrations of PM10 and PM2.5 suspended dust occur in Bialystok in the months of X-III, due to the low emission from combustion of fuels.

Tematy:: porous materials

Opis:: 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 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.

Opis:: 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.
