Opis:
The photocatalytic process of phenol oxidation and Cr(VI) reduction in the presence of nano-silica modified titania was carried out. The activity of composites was tested using two different light sources. The photocatalysts with 10% of nanosilica showed the highest activity. The calcination temperature (200–800 °C) significantly determined the sensitivity of the obtained materials to the light source used. Photocatalysts alternately adsorbed and desorbed Cr(VI) ions from the reaction mixture during irradiation. In the one-component mixture, complete oxidation of phenol was observed using material calcined at 650 °C, after 3 h of UV-VIS irradiation. In the reaction mixture of Cr(VI) and phenol, the highest activity was demonstrated by photocatalyst calcined at 300 °C. The concentration of phenol decreased in proportion to the decrease of chromium ions. The obtained titania-silica composites showed oxidizing properties towards phenol and reductive properties toward Cr(VI) ions.

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:
Zeolity są uwodnionymi, krystalicznymi glinokrzemianami metali, w szczególności Na, K, Mg, Ca, Sr i Ba, I i II grupy układu okresowego. Obecnie znane jest ponad 35 zeolitów naturalnych i ponad 150 zeolitów syntetycznych. Wśród zeolitów syntetycznych do najważniejszych można zaliczyć zeolity typu NaP i Na-X, Na-Y, 4A-X a do naturalnych mordenit, klinoptylolit i chabazyt. Jedną z możliwości zastosowań zeolitów jest usuwanie z wód zanieczyszczeń promieniotwórczych. Podjęto badania dotyczące możliwości wykorzystania tych substancji do oczyszczania wód kopalnianych z nuklidów promieniotwórczych z wykorzystaniem zeolitów naturalnych i sztucznych. W badaniach skoncentrowano się na usuwaniu z wód naturalnych nuklidów promieniotwórczych. Prezentowane badania polegały na przepuszczaniu przez kolumny(ę) z zeolitami oczyszczanej wody i odbieraniu na wylocie z kolumny kolejnych porcji wody oczyszczonej. W ten sposób otrzymywano dla każdej z badanych mieszanin serię próbek, które następnie były poddawane preparatyce chemicznej i pomiarom z wykorzystaniem techniki spektrometrii ciekłoscyntylacyjnej. W badaniach wykorzystano zeolit syntetyczny typu NaP1. Zeolity typu NaP1 otrzymywane są w wyniku reakcji hydrotermalnej odpadów (popiołów lotnych – powstających w wyniku energetycznego spalania węgla) z ługiem sodowym (NaOH). Badania wykazały wysoką efektywność usuwania izotopów radu z wód przeznaczonych do spożycia oraz kopalnianych.
Zeolites are hydrated, crystalline aluminosilicate minerals, containing metals from I and II group of periodic table of elements, especially Na, K, Mg, Sr, Ca and Ba. Nowadays more than 35 different natural zeolites are known as well as 150 synthetic ones. Among the latter zeolites, the most important are zeolites of NaP1 and Na-X types, Na-Y and 4A-X, while among natural zeolites best known are clinoptylolite, chabazite and mordenite. One of the possibilities of zeolite application is removal of radioactive contamination from water. For removal of radionuclides from mine waters the investigations on use of natural and synthetic zeolites have been undertaken, aimed on removal of radium isotopes. Laboratory experiments were performed with use of columns, filled with zeolite materials, through which treated water was percolating and aliquots of purified water were collected at outlet. For each of zeolite bed a series of samples (aliquots) were analysed – the radiochemical preparation of samples was done to retrieve radium isotopes. The prepared samples were measured with use of liquid scintillation spectrometry. The tested zeolite materials were synthetic zeolite NaP1, produced in the hydrothermal reaction of fly ash and sodium base (NaOH) and clinoptylolite. The high efficiency of radium removal with application of this technique was found not only for mine waters but also for potable waters.

The paper presents the results of investigations of the oxygen content in oxygenated water in a co-current pipe aerator with the diameter of 200 mm, with stainless steel Białecki rings with the diameter of 12 mm, for two cases: when the air is supplied by a compressor and when it is supplied by a jet pump. The oxygen content in the oxygenated water was assayed using an LDO oxygen sensor. The investigations of water oxygenation in the aerator were carried out during technical exploitation of the Scientific Research Water Station of Warsaw University of Life Sciences. The oxygen content O2 in the oxygenated water was measured for the set air flow rate Qp equal to 50, 100 and 150 dm3 ×h-1 and water flow rate Qw equal to 10, 15 and 20 m3 ×h-1 . During the tests, the temperature T of the air supplied to the aerator was also measured. The water temperature was constant during the tests and it was equal to 12°C. The oxygen content O2 in the oxygenated water and the temperature T of the air supplied to the aerator were measured every 10 seconds. For each air flow rate Qp and water flow rate Qw being set, three measurement series were carried out and the obtained results were averaged. The researches were aimed on the determination of the influence of air and water flow rate on the oxygen content in the water oxygenated in a pipe aerator with use of a compressor and a jet pump. In the measurement range being tested, the effectiveness of water oxygenation increased with rise in the flow rate of the supplied air and decreased with rise in the flow rate of the supplied water. The effectiveness of water oxygenation was higher if obtained by means of a jet pump than of a compressor.

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:
Health problem from fluoride contaminated water is more acute in rural and small urban communities. Defluoridation of low contaminated water by inexpensive adsorbents is a substantial practice worldwide. In the study, low-cost sorbents have been investigated as replacements for current costly methods of removing the excess fluoride from water below the certain concentration. The adsorption capacity of iron oxide and cement clay in fluoride removal was investigated by the batch method. The equilibrium time was attained in 3 h and 2 h for iron oxide and cement clay, respectively. Optimum adsorbent dosage was found to be 5 g/dm3. Initial fluoride concentrations for the adsorption studies were 1.24 and 12.2 mg/dm3. Fluoride adsorption isotherm fitted well the Freundlich isotherm with the coefficient of determination >0.99 for both adsorbents. The fluoride adsorption capacity of iron oxide was found higher than that of cement clay due to the high surface area and charge of iron oxide. How-ever both substances can reduce F– contamination below the acceptable limits of 1.5 mg/dm3 for less contaminated water.

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 recovery of aluminum from water purification sludge is usually performed by making the solution acidic or basic. However, for economic reasons and reasons of safety, excessive doses of acid or base should not be utilized. Accordingly, the aluminum concentration in the leached solution is typically limited, thus the recovered aluminum cannot be directly reused as a coagulant. A nanofiltration (NF) membrane can be used in the acidic solution to concentrate high-valence metal ions. There-fore, in this work, H2SO4 was utilized to leach Al3+ ions from water purification sludge. Then, the Al3+ ion solution was concentrated using a low-price NF membrane. The effect of natural organic matter on the Al3+ ion concentrating efficiency in the filtration process has been elucidated. Experimental results reveal that Al3+ ions were effectively prevented from passing through the NF membrane, enabling a highly concentrated aluminum solution to be obtained. However, the presence of organic compounds may reduce the efficiency of the concentration of Al3+ ions in the solution.

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.

W artykule przedstawiono ocenę możliwości zastosowania osadów zawierających żelazo, pochodzących z oczyszczania wody, jako zamiennika części wsadu rudnego w procesie spiekania rud żelaza. Przeprowadzono laboratoryjne próby spiekania, z udziałem do 5% osadów z oczyszczania wody w mieszance spiekalniczej. Stwierdzono, że wraz ze wzrostem udziału osadów w mieszance spiekalniczej pogarsza się jej przewiewność, a w konsekwencji wydajność procesu. Udział osadów z oczyszczania wody w mieszance spiekalniczej nie powinien przekraczać 1% mas.
This article presents the assessment of the possibility to use iron-containing sediments derived from a water purification as a replacement for the part of ore load in the iron ore sintering process. Laboratory sintering experiments were carried out, with up to 5% of sediments in the sintering mix. It was found that with the increase in the proportion of sediments in the sinter mix, the decrease of the permeability of sinter mix occurs and as a consequence, the process productivity decreases. The share of sediments of the water purification in the sinter mix should not exceed 1 wt.%.
