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:: This study evaluates the feasibility of using tamarind (Tamarindus indica) seed powder for de-fluoridation of fluoride contaminated water. Batch study confirmed that tamarind seeds in dry powder form could remove 87% of fluoride from water. This bio-sorbent can be used effectively in areas where fluoride concentrations are above the permissible limits of 1.5 mg·l-1 as per WHO Standard, 1984. Tamarind seed powder was incorporated in a matrix of sodium alginate and made into gel-beads. The beads were tested for de-fluoridation efficiency by conducting column studies. The effect of various factors, such as flow rate, retention time, and the number of runs on the efficacy of fluoride removal was also studied. The results revealed that flow rate did not seem to have much effect on the percentage fluoride removal but the fluoride concentration decreased drastically upon greater retention time and multiple runs.

Opis:: Processes of water purification from phosphates using a low-pressure reverse osmosis membrane were studied. It was shown that the concentration of phosphates in the permeate largely depends on their initial concentration in the water and increases along with the degree of permeate selection. It was established that when using the Filmtec TW3–1812–50 membrane for phosphate concentrations up to 20 mg/dm3, their concentration in the permeate does not exceed 2.5 mg/dm3 with a degree of permeate selection up to 90% when cleaning solutions in distilled and artesian water. This value is below the permissible level for drinking water. When the concentration of phosphates increases to 100 and 1000 mg/dm3, their content in the permeate increases sharply to the values significantly higher than the permissible level in both drinking and wastewater. When sodium orthophosphate was added to artesian water, the effectiveness of its purification on this membrane with respect to chlorides, sulfates, hardness ions, and hydrocarbons was high. This indicates that the cartridges with these membranes can be used both in industrial installations and in households for further purification of artesian and tap water to drinking water quality.

Opis:: The research goal was to develop an improved water purification technology for public reservoirs by adding the vibrocavitation purification before a reagent method with sodium hypochlorite, produced via electrolysis of salt. The main tasks of the research include the determination of vibrocavitation treatment efficiency and the development of a new low-frequency vibration resonance cavitation process for water purification, as well as equipment for this process. The vibroresonance method supporting the intensity of spatial displacements of cavitation exciters was developed on the basis of the theory of cavitation fields in liquids. While using this method, it was possible to establish the boundary conditions for stable support of the cavitation field created by low-frequency vibrations. The developed method is based on the formation of high intensive cavitation fields in liquids by vibratory decks. The advanced technological scheme of water purification for pools and public use reservoirs was proposed, which includes the addition of resonance vibrocavitators to a closed circulation cycle of water purification with the reagent method.

Opis:: W pracy przeprowadzono analizę ekonomiczna złóż sorpcyjnych stosowanych do oczyszczania wody. Wybrano takie masy węglowe jak: złoże Organosorb 10, złoże Norit ROW 0.8 Supra, złoże Hydroantracyt N oraz złoże K110. Ekonomicznego uzasadnienia doboru konkretnych złóż dokonano w oparciu o koszt zakupu złóż filtracyjnych, opłata środowiskowa za pobór wody, koszt urządzeń do napowietrzania wody, koszt odczynników chemicznych do regeneracji złóż, koszt pompy dozującej reagenty do regeneracji powstających podczas prowadzenia procesu adsorpcji z zastosowaniem każdego z wybranych do analizy złóż. Najtańsze w eksploatacji okazało się złoże K110, najdroższe zaś Norit ROW 0.8 Supra. Koszty eksploatacji złóż adsorpcyjnych zależy głównie od zakupu adsorbentu i prędkości adsorpcji. Ponadto znaczny udział w kosztach eksploatacji złóż węglowych ma opłata środowiskowa za pobór wody, mniejszy niż zakup samego złoża.
In the paper an economic analysis of the sorption deposits used for water purification was performed. Such masses of carbon as Organosorb 10 deposit, Norit ROW 0.8 Supra deposit, Hydroantracyt N deposit and K110 deposit were selected. The economic substantiation for the selection of specific deposits was based on the purchase cost of filter deposits, the environmental fee for water intake, the cost of equipment to aerate water, the cost of chemicals for deposits regeneration, the cost of the dosing pump reagents for regeneration generated during the process of adsorption using each of the deposits selected to the analysis. K110 deposit turned out to be the cheapest in the exploitation and Norit ROW 0.8 Supra was most expensive. The operating costs of the adsorption deposits depend mainly on the purchase of the adsorbent and the speed of adsorption. Moreover, environmental fee for water intake constitutes a significant share in the costs of exploitation of carbon deposits , which is greater than the deposit costs.

Opis:: The processes of manganese (II) ions removal from water using sorbent catalysts and ion exchange materials modified with iron oxides were studied. It was shown that manganese ions oxidize very slowly in artesian water, even when the pH is adjusted to 9.0. Intensive aeration of solutions due to stirring also does not promote the oxidation of manganese (II) ions. The degree of manganese extraction due to oxidation is reduced from 20–30% for solutions with a concentration of manganese ions of 1 and 5 mg/dm3 to 11–15% for solutions with a concentration of 15 and 30 mg/dm3. A significant increase in the oxidation efficiency of manganese ions was achieved by using magnetite as a sorbent catalyst. The efficiency of water demanganization increases along with the intensity of water aeration when mixing solutions. It was established that strongly acid cation exchangers provide efficient extraction of manganese ions from water. At the same time, a high exchange capacity of strong acid cation exchange resin KU-2–8 in acid and salt form was noted. It was shown that the capacity of manganese ions of this cation exchange resin in the Ca2+-form is slightly lower. When using the KU-2–8 in Ca2+-form of cation exchange resin to remove manganese ions from the solution already in the first samples, the leakage of manganese ions at the level of 10 mg/dm3 and above was observed. This indicates that this form of ion exchanger is not suitable for deep purification of water from manganese (II) ions. In order to increase the efficiency of manganese ion extraction from water, increase the duration of the filter cycle, magnetite and magnetite-modified KU-2–8 cation exchange resin were used as a sorbent-catalyst. It was shown that the cation exchange resin modified with magnetite provides the removal of a significant part of manganese ions due to catalytic oxidation on magnetite. The conditions of effective manganese extraction under static and dynamic conditions are determined.

Opis:: W pracy podjęto temat samooczyszczania wód w kaskadach zbiorników wodnych. Przedstawiono wyniki badań hydrobiologicznych trzech zbiorników zaporowych (Tresna, Porąbka i Czaniec), tworzących kaskadę rzeki Soły. Określono status troficzny zbiorników na podstawie stężenia chlorofilu, wielkości biomasy fitoplanktonu i występowania wskaźnikowych gatunków glonów planktonowych. Wyniki badań wskazały na obniżanie trofii wód w układzie od najwyższego do najniższego zbiornika kaskady. Średnie stężenia chlorofilu wynosiły odpowiednio 19,99 μg∙dm^-3, 8,74 μg∙dm^-3 oraz 4,29 μg∙dm^-3, natomiast średnia wielkość biomasy 4,1 mg∙dm^-3, 3,4 mg∙dm^-3 i 0,1 mg∙dm^-3. Obserwowane gatunki glonów planktonowych potwierdziły istnienie różnic między zbiornikami. W Tresnej rozwijało się więcej gatunków wskazujących na eutrofię, zaś w Porąbce oraz Czańcu rozwijały się gatunki występujące w wodach oligomezotroficznych. Samooczyszczanie wód w kaskadzie Soły, wyrażone obniżaniem ich żyzności, jest ważne dla gospodarki wodnej regionu, gdyż zbiornik Czaniec pełni funkcję zbiornika wodociągowego.
In this thesis the subject of water self-purification in cascade systems of water reservoirs was engaged. The results of hydrobiological research of three dam reservoirs (Tresna, Porąbka and Czaniec), creating the Soła river dam cascade were presented. The trophic status of these reservoirs was defined on the grounds of the concentration of chlorophyll a, biomass of phytoplankton and occurrence of indicating species of planktonic algae. The results of research indicated on decreasing of water trophy in the layout from the highest into the lowest reservoir of the cascade. The average concentrations of chlorophyll a amounted appropriately 19,99 μg∙dm^-3, 8,74 μg∙dm ^-3 and 4,29 μg∙dm^-3, instead the average biomass of phytoplankton amounted appropriately 4,1 mg∙dm^-3, 3,4 mg∙dm^-3 and 0,1 mg∙dm^-3. The observed species of algae confirmed occurrence of differences between reservoirs. In Tresna reservoir more species of phytoplankton indicating for eutrophy were thrived, instead in Porąbka and Czaniec reservoirs the species occurring in oligomesotrophic water thrived. Water self-purification in the Soła river dam cascade expressed decreasing of their fertility is important for water management of the region, because the Czaniec reservoir fulfill a function of water-supply reservoir.

Opis:: Clay minerals, as adsorbents, are widely available, have large specific surface area, and the ability for cation exchange, which makes them applicable in wastewater treatment from heavy metal ions. This study investigated the effect of acid modification on the porous structure and adsorption properties of montmorillonite (MMT) and palygorskite (PAL) clays of the Cherkasy deposit (Ukraine). Acid modification of clay samples was carried out with chloride acid after preliminary refining. Clay particles were analyzed using optical polarization microscopy with recording of digital images of the study. The area and perimeter of individual particles of clay samples were determined. The equivalent diameter and shape factor were calculated. The porosity characteristics of the samples were determined. Pore surface area was calculated by the Brunauer-Emmette-Teller (BET) method. Total volume, mean diameters, and pore size distribution were obtained using the Density Functional Theory (BFT) method. Acid modification improved the porous structure of clay samples. BET surface area of the pores of the initial sample of palygorskite clay is significantly higher compared to the montmorillonite type clay (140.66 and 83.61 m2/g, respectively). Acid modification of the PAL sample contributes to an increase in the BET surface area by approximately 1.7 times. Acid modification increases the surface area and total pore volume by approximately 2.3 times for MMT samples and 1.76 times for PAL samples. Dimensional characteristics of the pores of the MMT sample were to shift after activation, while for the PAL sample, their average size increases sharply by approximately 3.2 times. This suggested the additional formation of pores in the interfibrillar regions of the PAL sample during its acid activation. The effect of acid modification on the sorption capacity was investigated by means of methylene blue exhaustion. Sorption efficiency increases by 6-14%, compared to unmodified samples and is determined by the contact time and the type of clay. Increasing the contact time from 24 to 72 hours leads to an increase in the sorption efficiency of activated MMT and PAL samples by 36 and 30%, respectively. Acid-activated clay minerals, in particular montmorillonite, can be used as part of sorption elements to increase the efficiency of wastewater treatment technologies from heavy metal ions.

Opis:: The self-purification capacity of river water is an essential indicator for a healthy river. Various organic and inorganic pollutants, both from point sources and nonpoint sources, in most streams in Banjarmasin were beyond the river self-purification capacity, which caused a decrease in the river water quality. This study attempted to identify the river water pollution distribution in the city of Banjarmasin and determined the self-purification points. We used the purposive sampling technique to carry out river water sampling, with criteria for pollutant sources and distance of pollution taken into consideration. By using the trend analysis techniques, we analyzed the parameters concentration to relate it to the range of pollution so that we were able to identify the pollution distribution and determine the self-purification distances. The results indicated that the self-purification process could take place on the river flow in of Banjarmasin even though it did not reach the clean water zone. The river in Banjarmasin requires a longer purification distance so that the self-purification process can run correctly.

Opis:: Water is very plentiful through the planet in general. Nevertheless, clean drinking water is not always accessible in the proper time or place for sufficient public or ecological use. The water significance is emphasized by the fact that in the past, great cultures have arisen near and along water bodies. Water quality of some purification complexes (compact units) in the Babylon Province (13 compact unit) as compared with Al-Hillah Al Mouahad Project (water treatment plant) was assessed by the Water Quality Index (WQI) methodology. WQI offers a particular number that states the overall water quality at a definite place and period based on many parameters concerning the quality of water. The water produced from the compact units was classified as "good water" according to the WQI classification with the values ranging from 85.4 in Bermana unit to 99.17 in Al-Muamera compact unit. Moreover, the research results showed that the water purification complexes work with efficiency, very close to the performance of large water purification projects and stations, and this means that it is possible to rely on them to obtain good drinking water quality, especially in small or remote areas.

Opis:: In order to solve the problem of providing the population with high-quality drinking water, preference is given to the use of groundwater deposits, which differ from surface sources in better quality and are more protected from man-made influences and climate change. Thirty-seven existing groundwater deposits are used for drinking and technical water supply in Lviv region. The distribution of groundwater in the region is very uneven, and in the Eastern Carpathians they are almost non-existent. The main factors of groundwater pollution in most of Ukraine are municipal sewage, livestock effluents, unorganized warehouses for storage of industrial waste, fertilizers and pesticides and other local objects that affect the state of groundwater. The gradual reduction of mineral fertilizer and pesticide usage has led to some improvement in the quality of groundwater, but for some agro-industrial areas the presence of residual pesticides and nitrogen compounds in groundwater remains a relevant problem. This year, there was an increase in the use of mineral fertilizers compared to last year. The aim of this work was to study the compliance of the maximum allowable concentrations of hydrochemical parameters of the wells of the Stryi water intake and to determine the potential impact of anthropogenic factors on water quality. The compliance with the sanitary and hygienic requirements of the hydrochemical parameters of water in the wells of the Stryi water intake was analyzed. The regularities of their changes as well as the presence of wells that have a potentially unstable chemical composition and are prone to deterioration of water quality were determined. The results of studies of related to the impact of self-treatment processes in the river Stryi on the quality of water intake in the city of Stryi showed that the drinking water from artesian wells is of high quality and now there are no negative effects of river water in the Stryi basin on groundwater deposits. The quality of river water is satisfactory for its use in domestic and drinking water supply and for recreational purposes.

Opis:: Otrzymywany w procesie fermentacji metanowej biogaz jest mieszaniną gazów, więc niezbędna jest jego tania i skuteczna waloryzacja. Potrzeba badań nad tym procesem wymuszona jest koniecznością zastosowania biogazu jako odnawialnego źródła energii. Celem niniejszej pracy było zaprezentowanie metody oczyszczania i wzbogacania biogazu w zawiesinie popiołowo-wodnej, sporządzonej na bazie popiołów lotnych, powstałych ze spalania węgla kamiennego w energetyce zawodowej. Doświadczenie wykazało, że popioły lotne pochłaniają CO₂ i H₂S nawet w warunkach konwencjonalnych. Sprawność pochłaniania uzależniona jest nie tylko od składu chemicznego popiołów ale również od ich właściwości fizycznych. Zaobserwowano również neutralizację silnie zasadowego odczynu odpadów paleniskowych.
Biogas, produced in an aerobic digestion process, is a mixture of gases, and that is why its inexpensive and effective valorisation is essential. Research on this process is necessary in order to use biogas as a renewable energy source. The aim of this thesis is to present methods of biogas purification and enrichment in the fly ash - water mixture, that is generated on the base of fly ash produced during burning coal in power industry. Experience presented that the fly ash absorbs CO ₂ and H₂S, even in conventional conditions. The absorption efficiency depends not only on the chemical composition of the ash but also on its physical properties. There was also a strong neutralization of alkaline waste combustion.
