Aim of the study: This study aims to develop the novel model of multi-electrode MFC with the termite-associated yeast G. reessii for MG decelorization and electricity generation. Material and methods: The termite-associated yeast G. reessii was inoculated into modified midia with 150 mg/L MG. The laccase activity and MG removal was studied. Then, the G. reessii was immobilized on anode surface. The electrical properties and color removal were tested. Results and conclusions: The results showed it successfully removed the MG with 98.15±0.92% within 1 day of operation. Moreover, the OCV, CD and PD of 550.00±10.00%, 3.90±0.10 A/m3 and 1.52±0.08 W/m3 were achieved. Therefore, the system could have the potential for treatment of high concentration MG contaminated wastewater and produce a bio-electric energy.

Aim of the study. The aim of this study is to assess the variability of the lowest monthly totals of precipitation, and to evaluate the impact of atmospheric circulation on the occurrence of months with a deficit of precipitation. Material and methods. Material: The monthly totals of atmospheric precipitation for the years 1951–2017 from 19 meteorological stations located in the Polish Tatra Mountains and in their foreland. and the calendar of atmospheric circulation types for southern Poland, which was developed by Niedźwiedź (1981; 2018). Methods: Standardized Precipitation Index (SPI), the Mann-Kendall test Results and conclusions. No statistically significant trend at a significance level of 0.05 was noted in the course of the lowest monthly precipitation totals at any of the meteorological stations. In the 67-year period, all the measuring stations saw a total of 499 (3.3%) dry months with varying drought severity. The largest number of extremely dry months occurred in August and April, respectively. In the case of months when the lowest totals of precipitation occurred in the same month at all or almost all of the meteorological stations, three types of anticyclonic circulation dominated, i.e. eastern, south-eastern, southern, and the anticyclonic wedge.

Aim of the study: In this study, the spatial and temporal characteristics of drought in the upper and middle Cheliff; a semi-arid region of northwestern Algeria was examined using the standard precipitation index [SPI] at an annual time scale as a tool for measuring the severity of meteorological drought. Material and methods: To asses of SPI annual sum of precipitation from 11 precipitation stations covering the period 1970-2009 were used. In order to identify the possible changes in the precipitation trend of the studied series, statistical tests were selected. The extent, severity and duration of the drought in the study area were obtained. Results and conclusions: Statistical tests showed that the occurrence of ruptures in the rainfall regime was detected at the end of the 1970s and the beginning of 1980s with a negative trend. The results of the SPI showed a strong existence of dry years after 1979 and 1980. The years 1993, 1999 and 2001 presented an extremely severe drought (SPI <-2). The evolution of SPI showed a dominance of the frequency of normal years (67%) and alternation of dry years (17%) and wet years (16%) over a period of 40 years. The total surface of the study area is affected by drought during severe years (1993, 1999). The study area exhibits irregularity and heterogeneity of drought due to the great variability of precipitation, it can vary from sub-basin to another and from one year to another.

Cel pracy: Celem przeprowadzonych badań jest określenie możliwości zastosowania równania Colebrooka-White’a z modyfikacjami jego stałych K1, K2 i K3, zaproponowanych przez różnych autorów badań oporów przepływu wody w kanałach otwartych, z uwzględnieniem wpływu szorstkości ziarnowej dna potoku górskiego. Obliczone bezwymiarowe współczynniki oporów umożliwiły obliczenie współczynników szorstkości dna potoku Racławka. Materiał i metody: Badania przeprowadzono w korycie potoku Racławka. Na podstawie pomiarów terenowych prędkości przepływu wody obliczono natężenie przepływu wody Q, a następnie obliczono średni współczynnik szorstkości Manninga formułą opracowaną przez Barnesa. Współczynnik ten umożliwił obliczenie współczynnika szorstkości wyznaczonego z przekształconego równania Chézy-Maninnga. Obliczony współczynnik oporów porównano z wynikami obliczeń z równania Colebrooka-White’a ze stałymi K1, K2 i K3. Ponadto w tych obliczeniach przyjmowano wartości chropowatości bezwzględnej ks, wyznaczonej z 25 wzorów podanych przez różnych autorów. W celu obliczenia wartości ks pobrano próbę rumowiska i określono jej skład granulometryczny. Obliczono również współczynniki szorstkości z przekształconego równania Chézy-Maninnga dla poszczególnych wartości współczynnika oporów za pomocą modyfikacji równania Colebrooka-White’a. Wyniki i wnioski: W wyniku pomiarów obliczony współczynnik szorstkości dla tego potoku wynosi 0,044 m-1/3∙s. Stwierdzono, że z równania Colebrooka-White’a ze stałymi K1, K2 i K3, wyznaczonymi przez Keulegan i przez Rouse, dla wartości chropowatości bezwzględnej (ks) mieszczącej się w przedziale od 0,063 do 0,066 m, która została obliczona wzorem Thompsona i Campbella oraz wzorem Irmay’a, możliwe jest uzyskanie wartości współczynnika oporów, dla którego współczynnik szorstkości jest najbardziej zbliżony do uzyskanego z pomiarów. Współczynnik szorstkości badanego odcinka potoku Racławka, obliczony za pomocą tej modyfikacji równania Colebrooka-White’a, mieści się w granicach wartości 0,040 – 0,048 m-1/3∙s.

30-059 Krakow ABSTRACT Aim of the study The main aim of the research was to verify the thesis that formal and legal restrictions on the use of phosphorus compounds, particularly polyphosphates, in detergents extensively introduced in recent years reduced the concentration and load of this nutrient in raw sewage inflowing to the selected treatment plant. Additionally, it was tested whether the phosphorus decreasing in raw sewage reduced the concentrations and loads of total phosphorus in treated sewage, and thus reduced negative sewage anthropopressure of the water body. Material and methods This paper presents observations accumulated during the 15-years study (2003–2015), the concentrations and loads of total phosphorus in domestic sewage flowing into the selected treatment plant, as well as in treated sewage discharged into the receiving water body. A total of 148 samples of raw sewage and 114 samples of treated sewage were collected over the research period. The concentration of the total phosphorus in wastewater was determined by spectrometry with ammonium molybdate. The research results were analysed with the aid of advanced statistical analysis using, among others Mann-Kendall test, Kolmogorov Smirnov test, elements of descriptive statistics, as well as regression analysis with selected that only for one analysed sewage treatment plant, the annual phosphorus content in the wastewater would reduce the trophic mass growth by nearly 33 tons, in comparison to the period when no restrictions were applied to the content of polyphosphate in detergents.
