AB  - Usled razvoja industrije i rastom populacije tokom poslednjih godina javljaju se
problemi u vezi sa otpadnim vodama iz proizvodnje koje je neophodno rešavati na ekološki i
ekonomičan način. Sve otpadne vode iz postrojenja bez obzira kako su nastale sadrže štetne
materije koje mogu da imaju i određen stepen toksičnih primesa, moraju se prečistiti ako njihov
kvalitet ne odgovara zakonskim okvirima. Svrha tretmana otpadnih voda je uklanjanje štetnih
materija čime se postiže smanjnje stepena njene zagađenosti, a istovremeno se ostvaruje i određen
ekonomski i ekološki efekat, stoga je u ovom radu izvršeno prečišćavanje otpadne vode postupkom
taloženja upotrebom kalcijum-oksida u cilju uklanjanja koloidnih materija i teških metala. Većina
zagađujućih materija su organskog porekla i njihovo ukljanjanje vršiće se primenom naprednih
oksidacionih procesa korišćenjem ozona i ozona u kombinaciji sa ultrazvukom u cilju postizanja

AB  - Due to the development of industry and population growth during the in recent years, there are problems with wastewater from production that needs to be addressed in an environmentally and economical way. All wastewaters from industry, no matter how they are created, contain harmful substances that may have some degree of toxicity, must be treated if their quality does not meet the legal requirements. The purpose of wastewater treatment is to remove
harmful substances, thereby reducing its pollution level, and at the same time, it also has a certain economic and environmental effect. Therefore, wastewater treatment was carried out in this work by precipitation using calcium oxide to remove colloidal substances and heavy metals. Most pollutants are of organic origin and their removal will be carried in this work out using advanced
oxidation processes using ozone, and ozone in combination with ultrasound to achieve water quality that complies with the law. The purification process will be optimized with respect to, method, time and amount of oxidizing agent applied. The degree of pollution of water by organic compounds will be determined on the basis of measurements of HPK, BOD and the concentration of heavy metals (lead, ferrum, chromium, copper, zinc, aluminum).

AB  - Waste  water  treatment  sludge  is  generated  in  increasing

useful  (active)  microorganisms  that  can  be  reused  in  waste  water

AB  - Sušenjem mulja iz procesa prečišćavanja otpadnih voda mogu se dobiti dva glavna upotrebljiva proizvoda: osušeni mulj može se skladištiti i koristiti kao organsko đubrivo, a može sadržati i aktivne (žive) mikroorganizme koji se ponovo mogu koristiti u tretmanu otpadnih voda. Sušenje suspenzija i pasta u fluidizovanom sloju inertnih čestica predstavlja atraktivnu alternativu ostalim postupcima sušenja u pogledu osnovnih kriterijuma za ocenu efikasnosti kao što su specifični kapacitet isparavanja, specifični utrošak toplote i specifični utrošak vazduha. Visoka efikasnost sušenja je rezultat velikih kontaktnih površina i velikih temperaturnih razlika između ulaznog i izlaznog toka vazduha za sušenje. Intenzivno mešanje inertnih čestica tokom agregativne fluidizacije obezbeđuje približno jednaku temperaturu u celoj zapremini sloja te ne postoji rizik od lokalnog pregrevanja. U radu su prikazani rezultati ispitivanja sušenja mulja na pilot postrojenju za sušenje suspenzija i pasta nominalnog kapaciteta isparavanja do20 kgH2O/h, čiji je centralni deo cilindrična kolona prečnika 215 mm sa fluidizovanim slojem staklenih sfera. Ispitivan je uticaj operativnih uslova na performanse sistema za sušenje i na kvalitet praškastog osušenog aktivnog mulja. Glavni cilj je da se odrede optimalne temperature sušenja mulja pri kojima bi korisni mikroorganizmu u mulju ostali aktivni (živi), a pri kojim aktivni mulj može da se koristi kao oragansko đubrivo. Izvršena je analiza efikasnosti sušenja sa stanovišta kapaciteta isparavanja i potrošnje vazduha u cilju boljeg sagledavanja performansi sistema za sušenje.

AB  - Systematic modification of three structurally different minerals (zeolite, mica, and vermiculite) was carried out with the aim of determining the modification mechanism and exposing the hydrophobic surface that can be used as a sorbent for many organic compounds. Mechanism of modification with cationic surfactant depends strongly on the mineral type. In order to identify the influence of aluminosilicates structural differences on the modification process, adsorption experiments with organic matter and water vapor, supplemented with the DTA/TG analysis, were performed. The cation exchange capacity (CEC) value was 1454>560>28meqkg(-1) for zeolite (clinoptilolite), vermiculite, and mica (muscovite), respectively. Despite its CEC value, vermiculite adsorbed three times the amount of organic matter than did clinoptilolite due to the porous structure of zeolite, which acted to limit the adsorption only on the external exchangeable cations. If the loading amount is equal to the CEC or the external cation exchange capacity for clinoptilolite (ECEC approximate to 10% CEC), the monolayer will form while mineral surface will have hydrophobic character. Only one active center exists at the surface of the clinoptilolite that was identified by DTA curves with a sharp and defined peak around 300 degrees C and by the mass loss at the TG diagrams. Two significant and equal active centers were observed in vermiculite, one for the exchange of the surface cations and the other for the interlayer cations and H2O molecules. Muscovite CEC is negligible, and due to the absence of any other functional groups, the modification of this mineral was impossible.

AB  - In this paper the ability of three natural zeolites from different localities (Vranjska banja-VB, Igroš-I and Baia Mare-BM deposits) to remove copper has been investigated. These three zeolites were subjected to the elementary analysis as well as XRDP and DTA/TG analysis due to complete characterization. Cation exchange capacity of VB, I and BM zeolites were 150.1, 169.2, and 176.5 meq/100g. The maximum adsorption capacity for the copper adsorption on VB, I and BM-zeolites were 7.75, 8.51, and 11.18 mg/g. Based on the obtained results the mathematical expression that describes correlation between the CEC and copper adsorption capacity has been developed. This linear dependance has been tested with the vast variety of experimental results. According to this expression it is possible to predict the copper adsorption capacity for different zeolites based only on their CEC value.
AB  - U radu su prikazani rezultati ispitivanja uklanjanja jona bakra primenom tri prirodna zeolita sa različitih lokaliteta (Vranjska banja-VB, Igroš-I i Baia Mare-BM). U cilju karakterizacije zeolita, izvršena su ispitivanja elementarnog sastava, kao i rentgenska (XRDP) i termijska analiza (DTA/TG). Kapaciteti katjonske izmene (CEC) ispitivanih zeolita VB, I i BM iznose 150,1, 169,2 i 176,5 meq/100g. Maksimalni adsorpcioni kapaciteti bakra na VB, I i BM zeolitima iznose 7,75, 8,51, i 11,18 mg/g. Na osnovu ostvarenih rezultata, dobijena je matematička zavisnost koja dobro opisuje vezu između vrednosti CEC i adsorpcionog kapaciteta za bakar. Ova lineralna zavisnost je testirana primenom različitih eksperimentalnih rezultata. Primenom ove zavisnosti moguće je da se predvidi vrednost adsorpcionog kapaciteta bakra na različitim zeolitima poznavanjem njegove CEC vrednosti. .

AB  - During the mining process of copper exploitation, a large amount of wastewater is generated. Not only do the copper ions contaminate the water but also represent a great loss for the copper production industry. Negative charges surface of zeolite has been used for adsorption of copper. The batch and dynamic experiments have been conducted. After the adsorption, the zeolite has been regenerated with the concentrated solution of Na-salt. The volume of the regenerative solution is 30 times smaller compared to the total amount of the waste solution that has been purified and the concentation of the obtained solution is 12 gCu2+/dm3.

AB  - The increasing levels of industrial wastewater released to the environment present a serious
threat to human health, living resources, and ecological systems. Fe-modified zeolites were developed and tested for removal of Cu2+ and Zn2+ from contaminated water. The surfaces of the naturally occurring zeolite, clinoptilolite, were modified with Fe(III) oxyhydroxides using three different methods, denoted I, II, and III (FeCli1 , FeCli2, and FeNaCli1, respectively). The oxyhydroxides were prepared in Method I using 0.1 M FeCl3 · H2O in an acetate buffer (pH = 3.6); in Method II, using 10% FeCl3 · H2O solution in 0.1 M KOH (pH = 10); and Method III was the same as Method I except the clinoptilolite was pretreated with NaCl. Newly synthesized materials from these three methods were then tested for their ability to enhance the sorption capacity for Cu and Zn compared to the natural sample (Cli). Powder X-ray diffraction measurements and the chemical composition of these modified samples confirmed that
clinoptilolite maintained its structure while amorphous Fe3+ species were synthesized. The specific surface area (BET method) of both the natural and modified clinoptilolite increased by 2 and 7.5 times for Methods I and II, respectively. Scanning electron microscopy and energy dispersive X-ray spectroscopy revealed that CaO was formed during Method I (FeCli1). Throughout the adsorption process, the hydrolysis of CaO and the release of OH¯ caused the precipitation of Cu and Zn hydroxide, which made the determination of the sorption capacity of FeCli1 impossible. This phenomenon was avoided in Method III (FeNaCli1) because of the absence of exchangeable Ca2+. The adsorption experiments with method II resulted in
double-enchanced adsoprtion capacity. Laboratory batch experiments have shown that the sorption capacities increased in the following order: Cli < FeCli2 < FeNaCli1, for Cu: 0.121 mmol/g < 0.251 mmol/g < 0.403 mmol/g and for Zn: 0.128 mmol/g < 0.234 mmol/g < 0.381 mmol/g.
