AB  - Two conventional experimental procedures for determination of the water permeability of saturated porous medium are the constant and the falling head permeability tests. The first one is more applicable on more permeable materials where the outflow from the sample is measured at variety of constant water heads, while the second one is more convenient for low permeable materials, utilizing the continuous measurements of the water head falling due to filtration through the saturated sample. However, neither of the two is useful for materials of high permeability and large cross-sectional area. The constant head permeability test faces technical issues since a significant and continuous water discharge is required, while the falling head permeability test has limitations due to neglection of the Forchheimer's high-velocity flow through the sample, but also the influence of inertia on the fluid mass. Here we proposed an approach for determination of the water permeability of saturated porous medium based on the agreement between the measured water level change in two connected reservoirs containing a porous sample and the new semi-analytical expression describing that change by accounting for the mentioned theoretical deficiencies. This efficient approach has been tested on four pervious paver samples, and results showed satisfactory agreement with the constant head permeability data. It has been also confirmed the proposed semi-analytical solution is more accurate than the falling head permeability approach in case of highly pervious materials, while for low permeable materials it reduces to the conventional approach.

It has been also confirmed the proposed semi-analytical solution is more accurate than the falling head permeability approach in case of highly pervious materials, while for low permeable materials it reduces to the conventional approach.",

AB  - Prisustvo organskih boja u otpadnim vodama, većinom poreklom iz tekstilne industrije, može da prouzrokuje dugoročne štetne efekte na floru i fauni usled značajne stabilnosti i toksičnosti pri vrlo malim koncentracijama. Fotokatalitičko prečišćavanje otpadnih voda predstavlja jedan od najjednostavnijih i po okolinu najpovoljnijih procesa (neograničen izvor sunčevog zračenja, blagi reakcioni uslovi i potpuna demineralizacija polutanata). Bimetalni fotokatalizatori, ZnAl i ZnCr, mešoviti oksidi su sintetisani i ispitivani fotokataličkim reakcijama razgradnje različitih organskih boja (rodamin B i brilijant krezil plavo). Pored toga izvršena je strukturna i teksturalna karakterizacija. Zapažena je velika fotokatalitička aktivnost oba uzorka, gde je postignuta kompletna dekolorizacija (100%) brilijant krezil plavog polutanta, dok je efikasnost razgradnje rodamin B oko 75% za ZnAl i oko 50% za ZnCr fotokatalizator. Rezultati istraživanja ukazuju na značajan potencijal primene ovih bimetalnih mešovitih oksida u procesima fotokatalitičkog prečišćavanja otpadnih voda.

AB  - Various organic pollutants are discharged into the water from chemical, textile and
pharmaceutical industries every day. The photocatalytic wastewater treatment is an efficient,
cheap and eco-friendly process for the removal of organic toxic dyes, such as methylene blue,
which is one of the most common toxic dyes in wastewater. Photocatalysts ZnCr mixed
oxides were synthesized and thermally treated at 500 and 900 °C. Their efficiency in
photocatalytic degradation of methylene blue and the influence of the reaction parameters
were studied. High photocatalytic activity of both samples was observed, where the complete
decolorization (100%) and partial decolorization (45%) of the aqueous solution of methylene
blue were achieved after 6 hours for ZnCr 900 and ZnCr 500, respectively. In order to
determine the influence of the pH on the photocatalytic effieciency, the photodegradation
reactions were conducted using better performing photocatalyst at different pH values,
measuring the photodegradation efficiency at the same time intervals. The optimal pH
resulting in the most efficient photodegradation for ZnCr 900 photocatalyst was observed at
pH 12, which could be explained by the correlation with different textural and structural
properties of photocatalysts. The results showed that the obtained ZnCr mixed oxides are
highly efficient in the methylene blue photodegradation and have a great potential for the
application in the photocatalytic wastewater treatment processes.

AB  - Waste and recycled materials have recently been used in the construction industry to comply with the principles of circular economy and sustainable development. The aim of this paper is to examine the potentials of solidified wastewater treatment sludge (SWWTS) as a supplementary cementitious material (SCM) in the production of lightweight pervious concrete pavers (LWPCP) suitable for pedestrian trails and rooftops (green) that comply with EU standards. Detailed characterization of SWWTS was performed, in order to understand its properties related to application as SCM, which led to the conclusion that it may be applied only as a filler, having 89.5% of Ca(OH)2. After thorough characterization, LWPCP samples were prepared and testing of physical and mechanical properties was conducted. The research showed that partial replacement of cement with SWWTS led to the decrease of all mechanical properties, ranging between 3.91 and 5.81 MPa for compressive strength and 0.97 to 1.23 MPa for flexural strength. However, all of the investigated mixtures showed a value higher than 3.5 MPa, which was defined as the lowest compressive strength in the range of pervious concrete properties. The addition of SWWTS led to a slight decrease in bulk density of the mixtures and an increase in water absorption. This could be explained by the reduction in hydration products that would fill in the micropores of the matrix, since SWWTS showed no pozzolanic reactivity. Pore sizes that prevail in the tested binder matrices are in accordance with the results measured on ordinary pervious concrete (the largest fraction of pores had a diameter between 0.02 and 0.2 μm). Low thermal conductivity nominates produced pavers as potential rooftop elements.

AB  - Prirodom inspirisana rešenja za cilj imaju unapređivanje kvaliteta života u urbanim sredinama pospešivanjem biodiverziteta. Mnoga od ovih rešenja, kao što su zeleni krovovi i biofiltri, su takođe zanimljiva u pogledu smanjivanja i prečišćavanja kišnog oticaja u gradovima. S obzirom da se zasnivaju na procesu infiltracije, za procenu uticaja ovakvih rešenja na urbane (pod)slivove neophodno je koristiti fizički zasnovane i efikasne modele padavine-oticaj. U literaturi se može naći veliki broj modela različitih nivoa kompleksnosti i efikasnosti, pri čemu je neophodno naći kompromisno rešenje. U ovom radu su analizirana dva numerička modela zasnovana na rešavanju Richards-ove jednačine koji spadaju u grupu fiziči zasnovanih. Jedan od modela je standardna implicitna numerička shema, dok drugi koristi Ross (2003)-ovo eksplicitno numeričko rešenje. Modeli su testirana na eksperimentalnim podacima prikupljenim sa zelenog krova “Green Wave” i biofiltra na Univerzitetu Monash, a rezultati oba modela su poređeni međusobno u pogledu tačnosti i efikasnosti, a zatim i sa merenim vrednostima dreniranog oticaja. U slučaju zelenog krova gornji granični uslov je mereni intenzitet kiše a donji je slobodno dreniranje, dok se u slučaju biofiltra na gornjoj granici zadaje mereni ulazni fluks a na donjoj nulta vrednost kapilarnog potencijala. Zadati granični uslovi uzrokuju tečenje kroz nezasićeni supstrat zelenog krova, dok kod biofiltra dolazi i do potpunog zasićenja filterskog sloja. Implicitno i eksplicitno numeričko rešenje daju gotovo identične rezultate sa zanemarljivom greškom u bilansu, dok je eksplicitno rešenje skoro 3 puta efikasnije. Takođe, slaganje modeliranih i izmerenih vrednosti oticaja je zadovoljavajuće, pri čemu Nash-Sutcliffe koeficijent iznosi 0.91 u slučaju zelenog krova, odnosno 0.93 u slučaju biofiltra.

abstract = "Prirodom inspirisana rešenja za cilj imaju unapređivanje kvaliteta života u urbanim sredinama pospešivanjem biodiverziteta. Mnoga od ovih rešenja, kao što su zeleni krovovi i biofiltri, su takođe zanimljiva u pogledu smanjivanja i prečišćavanja kišnog oticaja u gradovima. S obzirom da se zasnivaju na procesu infiltracije, za procenu uticaja ovakvih rešenja na urbane (pod)slivove neophodno je koristiti fizički zasnovane i efikasne modele padavine-oticaj. U literaturi se može naći veliki broj modela različitih nivoa kompleksnosti i efikasnosti, pri čemu je neophodno naći kompromisno rešenje. U ovom radu su analizirana dva numerička modela zasnovana na rešavanju Richards-ove jednačine koji spadaju u grupu fiziči zasnovanih. Jedan od modela je standardna implicitna numerička shema, dok drugi koristi Ross (2003)-ovo eksplicitno numeričko rešenje. Modeli su testirana na eksperimentalnim podacima prikupljenim sa zelenog krova “Green Wave” i biofiltra na Univerzitetu Monash, a rezultati oba modela su poređeni međusobno u pogledu tačnosti i efikasnosti, a zatim i sa merenim vrednostima dreniranog oticaja. U slučaju zelenog krova gornji granični uslov je mereni intenzitet kiše a donji je slobodno dreniranje, dok se u slučaju biofiltra na gornjoj granici zadaje mereni ulazni fluks a na donjoj nulta vrednost kapilarnog potencijala. Zadati granični uslovi uzrokuju tečenje kroz nezasićeni supstrat zelenog krova, dok kod biofiltra dolazi i do potpunog zasićenja filterskog sloja. Implicitno i eksplicitno numeričko rešenje daju gotovo identične rezultate sa zanemarljivom greškom u bilansu, dok je eksplicitno rešenje skoro 3 puta efikasnije. Takođe, slaganje modeliranih i izmerenih vrednosti oticaja je zadovoljavajuće, pri čemu Nash-Sutcliffe koeficijent iznosi 0.91 u slučaju zelenog krova, odnosno 0.93 u slučaju biofiltra.",

AB  - Selection of the optimal method for the removal of heavy metals remains a scientific challenge in terms of efficiency, cost-effectiveness and preservation of environment. In this paper, the aim of the study was to remove the zinc ions (Zn2+) from a sample of real waste water from galvanizing plant. Method of electrocoagulation (EC), which is based on the separation of the solid phase, formed by the presence of dissolved ions from inserted electrode, has been tested and applied within this research. Based on the results obtained by electrocoagulation, it can be concluded that the method is efficient and can quickly remove zinc ions from solution. The optimal removal was achieved when concentration of Zn2+ ions was reduced from 46.9 to 1.89 mg/L, after 10 minutes of laboratory EC.
