Application of membrane techniques for the removal of micropollutants from water and wastewater
A number of inorganic anions and heavy metals, microorganisms, natural organic matter, and organic micro-pollutants, among them disinfection by-products, pharmaceutical active compounds and endocrine disrupting compounds, have been found in potentially harmful concentrations in numerous water sources. The maximum permissible levels of these compounds, in drinking water and wastewaters discharged to environment, set by the WHO and a number of countries are very low (from µg/L to a few mg/L).Several common treatment technologies, which are nowadays used for removal of inorganic and organic contaminants from natural water supplies, represent serious exploitation problems. Membrane processes such as RO and NF, UF and MF in integrated systems, Donnan dialysis and electrodialysis as well as MBR and liquid membranes, if properly selected, offer the advantage of producing high quality drinking water as well as purified wastewater which can be drained off to natural water sources.High-pressure membrane techniques, i.e. RO and NF can be used for direct removal of inorganic and organic micropollutants, while low-pressure (MF and UF) in integrated systems, first of all with coagulation and adsorption and in MBR as well as after complexion with polymers or surfactants.Processes with ion-exchange membranes are suitable for micropollutants having electrical charge. Because of that property they are used in many large scale applications including the separation of ions, desalination, removal of ionic species etc.
Hellenistic coins from the Jagiellonian University excavations at the hellenistic-roman agora of Nea Paphos (Paphos Agora Project 2011-2019) : preliminary observations
Niniejszy artykuł jest krótką i bardzo wstępną informacją na temat monet hellenistycznych odkrytych podczas prac wykopaliskowych prowadzonych przez archeologów z Instytutu Archeologii UJ na agorze starożytnego Nea Pafos w latach 2011–2019. Pierwsze badania archeologiczne agory przeprowadził na przełomie lat 60. i 70. XX w. Kyriakos Nicolaou. Zespół archeologów z Uniwersytetu Jagiellońskiego pod kierownictwem Ewdoksji Papuci-Władyka rozpoczął eksplorację terenu agory w 2011 r. Podczas polskich wykopalisk znaleziono co najmniej 480 monet i krążków monetarnych. Znaczna część z nich (co najmniej 180 egzemplarzy) została wybita w okresie hellenistycznym. W skład tej grupy wchodzą głównie monety ptolemejskie (ponad 67%), ale także bite na Cyprze brązy typu Zeus/Zeus (20,5%), monety z regionu syro-palestyńskiego (Seleucydzi, Judea – ponad 6%), monety macedońsko-antygonidzkie (3,8%), monety z południowo-wschodniej części basenu Morza Egejskiego i Azji Mniejszej (1,6%) jak i inne. W artykule przedstawiono wstępne obserwacje dotyczące chronologii i struktury znalezisk.The present article is a short and very preliminary report about the Hellenistic coins found during excavations conducted by the team of the Institute of Archaeology, Jagiellonian University at the agora of the ancient Nea Paphos in 2011–2019. The first archaeological research at the agora had been conducted in the late 1960s and 1970s by Kyriakos Nicolaou. The Jagiellonian University team, led by Ewdoksia Papuci-Władyka started to explore the agora area in 2011. There were at least 480 coins and coin flans found during the Polish excavations. Great part of them are minted in the Hellenistic Period. The group consists mainly of Ptolemaic coins (over 67%), but includes also Cypriot bronzes of the Zeus/Zeus type (20.5%), coins of Syro-Palestinian region (Seleucid, Hasmonean rulers – over 6%), Macedonian-Antigonid issues (3.8%), the coins from south-eastern Aegean and Asia Minor (1.6%) as well as others. Some preliminary observations concerning chronology and structure of the finds are presented
Old finds of Roman coins in the archives and collection of the National Museum in Krakow III : Dr Wacław Pancerzyński and discoveries of Roman coins in Volhynia
Before World War II, some Roman coins discovered in Volhynia were added to the numismatic col-
lection of the National Museum in Krakow (NMK). Some of them were donated by Dr Wacław Pancerzyński, a physician and a major in the Polish Army. He obtained the coins during his service in the Border Protection Corps in Mizocz in what was then Zdołbunowski poviat (today Mizoch, zdolbunivs’kii raion, rivnens’ka oblast’, Ukraine). The three coins, donated in 1927, were most likely part of a hoard of Roman denarii discovered that year in the vicinity of Mizocz. In turn, a bronze coin of Constantine the Great, type “Urbs Roma”, found in Buszcza (today Bushcha, zdolbunivs’kii rayon, rivnens’ka oblast’, Ukraine), entered the NMK collection in 1929. It remains to this day the only discovery of a Roman coin recorded in this town. Unfortunately, due to confusion and the loss of some archives during World War II, it is not possible to accurately identify the coins in the current NMK collection. The same holds true regarding the denarii of Trajan and Antoninus Pius found in another locality in Volhynia, Międzyrzecz Korecki (today Velyki Mezhyrychi, koretskyi raion, rivnens’ka oblast’, Ukraine), donated by Dr Stanisław Tomkowicz. This find is well known in the literature. Unfortunately, we do not know how the donor, an outstanding figure known for his work for the protection of monuments in Kraków and Western Galicia, came into possession of these coins
Znaleziska monet władców Bosporu Kimeryjskiego na ziemiach polskich
Wśród polskich znalezisk starożytnych monet bitych w prowincjach Imperium
Romanum lub w państwach sąsiadujących z cesarstwem niedużą, ale interesującą
grupę tworzą te pochodzące z obszaru tzw. Królestwa Bosporańskiego. Chodzi tutaj
o monety bite między I wiekiem p.n.e. a IV wiekiem n.e. Z terenu dzisiejszej Polski
znamy jak dotąd sześć takich znalezisk. Cztery z nich zostały dokonane w okresie
do około połowy XX wieku. Są to dziewiętnastowieczne odkrycia w Staniątkach
i Zarzeczu, znalezisko z lat 30. XX wieku z Gorlic-Glinika Mariampolskiego
opublikowane w 1973 roku oraz pochodzące sprzed 1953 roku znalezisko z okolic
Nowego Sącza-Zabełcza. Już w erze powszechnego używania wykrywaczy metali
dokonano odkryć interesujących nas monet bosporańskich w miejscowości Skłóty
(pow. kutnowski) i w Gąskach (pow. inowrocławski). Pochodzą one z obszaru
osadnictwa kultury przeworskiej lub z terenu polskich Karpat Zachodnich
objętego osadnictwem kultury puchowskiej, a później przeworskiej. Wszystkie
monety bosporańskie odkryte na ziemiach polskich należą do emisji brązowych,
a czas ich wybicia zawiera się pomiędzy końcem I wieku p.n.e. a połową
III wieku n.e. Tym samym należą one do tzw. grupy I (monety wybite przed
tzw. wojnami gockimi) i II (monety bite w okresie wojen gockich) według klasyfikacji
G. Beidina i K. Myzgina opartej na licznych znaleziskach z obszaru Ukrainy i Rosji.
Jest bardzo prawdopodobne, że monety te dotarły na obszar dzisiejszej Polski
ze wschodu za pośrednictwem kontaktów z Sarmatami lub „gocką” ludnością kultury
czerniachowskiej. Mniej prawdopodobny, choć niewykluczony, jest ich napływ
z południowego wschodu, z obszaru Dacji lub Mezji, albo z południa.Among the finds in Poland of ancient coins struck in the provinces
of the Imperium Romanum or in the empire’s neighboring states, a small but
interesting group consists of coins from the so-called Kingdom of the Cimmerian
Bosporus. These are coins that were struck between the 1st century BC and the 4th
century AD. We know of six such finds from the lands of present-day Poland. Four
of these coins were found before the mid-20th century. Of these four, two were found
in the 19th century – one in Staniątki and one in Zarzecze; the third was found in the
1930s in Glinik Mariampolski, Gorlice, though it was not published until 1973; and
the fourth was found before 1953 near Zabełcze, Nowy Sącz. In the present age,
in which metal detectors have entered into common usage, one Bosporan coin has
been discovered in Skłóty, Kutno District, and one in Gąski, Inowrocław District.
They come from an area in which there were settlements of the Przeworsk culture or
from the lands of the Polish Western Carpathians in which there were settlements of
the Púchov culture and then, later, of the Przeworsk culture. All the Bosporan coins found on Polish lands were bronze issues struck between the end of the 1st century
BC and the middle of the 3rd century AD. Thus, they belong to what is called Group I
(coins struck before the so-called Gothic Wars) and Group II (coins struck during the
Gothic Wars), in accordance with G. Beidin and K. Myzgin’s classification, which is
based on numerous finds from Ukraine and Russia. It is very likely that the coins of
interest to us here made their way to the lands of present-day Poland from the east
via contacts with the Sarmatians or with the “Gothic” peoples of the Chernyakhov
culture. It is less likely – though it cannot be ruled out – that these coins came from
the southeast, from the region of Dacia or Moesia or from the south
A Late-Roman solidus found at Prełuki (the upper San River basin)
The aim of the article is to publish and discuss the late Roman solidus of Theodosius II (408-450), found in 2018 in the vicinity of the village of Prełuki, Komańcza commune, Sanok County. The coin was found randomly by treasure hunters, eventually recovered and donated to the Historical Museum of Sanok by Robert Fedyk. It is the second find of a late Roman solidus in the Upper San River basin. Several years ago a solidus of Valentinian III (425-455) had been found in Prusiek, Sanok County. Both coins belong to the early Migration Period finds horizon in this area. This consists of few bronze buckles, a sword, and fragments of a Hunnic cauldron finds. In all likelihood, the solidi found their way into the Upper San River basin as a consequence of the Hunnic-Germanic relations. They should be also treated as a part of the latest wave of Roman coins arriving in the present Lesser Poland area in the 5th century AD
Finds of counterfeit Roman denarii at selected Roman-period settlement sites in western Lesser Poland : the state of research and prospects
In recent decades, the number of archaeological excavations and surveys conducted at Roman-period sites in various regions of Poland, including western Lesser Poland, has increased significantly. These studies concern, inter alia, numerous settlement sites. Intensive, not always legal, exploration activities are also conducted by the so-called detectorists. Among the numerous finds of portable artefacts registered during regular research and illegal searches, monetary finds are distinguished by their number. Numerous finds of Roman coins have also been registered in settlement sites in western Lesser Poland, including especially first–third-century ad denarii, but also their counterfeits, such as denarii subaerati and denarii flati, as well as imitations. This article analyses finds of counterfeit Roman denarii made in several Roman-period settlements located in western Lesser Poland. First of all, the monetary finds from the Przeworsk culture settlement in Jakuszowice, Kazimierza Wielka county (site 2) were verified. All the finds from Jakuszowice were examined with a fluorescence X-ray spectrometer (Spectro-MIDEX type), which made it possible to distinguish a greater number of counterfeit denarii (thirty-four items) than in previous publications. The article also provides a short review of monetary finds from Roman-period settlements in Nieprowice, Boronice, Aleksandrowice, Modlniczka, and Mysławczyce
A Find of a Bosporan Coin at Trębaczów, site 2, Kazimierza Wielka District (Poland)
Der Artikel widmet sich einer Bronzemünze von Sauromates II., dem Herrscher des Bosporanischen Königreichs (174/175–210/211 n. Chr.). Das Stück wurde bei einer archäologischen Untersuchung der Siedlung Trębaczów (Fundstelle 2), Kazimierza Wielka Poviat, entdeckt, die in die Zeit der Przeworsk-Kultur datiert. Vom Nominal als »Dreifach Sestertius« oder »Drachme« angesprochen, gehört die Prägung zu den zwei Serien von Bronzemünzen, die in die Zeit um 186–196 n. Chr. (Zograf 1951; Frolova 1997a) oder in die Jahre um 180–192 n. Chr. (Anokhin 1986) datiert werden. Der neu entdeckte Fund erweitert eine kleine Gruppe bosporanischer Münzen, die zwischen der zweiten Hälfte des 1. Jahrhunderts v. Chr. und dem 4. Jahrhundert n. Chr. geprägt und auf dem Gebiet des heutigen Polen entdeckt wurden. Bisher waren sechs derartige Funde bekannt. Das neue Exemplar fand wahrscheinlich in der ersten Hälfte oder in den ersten Jahren der zweiten Hälfte des dritten Jahrhunderts n. Chr. durch Kontakte zwischen verschiedenen Bevölkerungsgruppen im ost- und mitteleuropäischen Barbaricum den Weg zur Siedlung der Przeworsk-Kultur.The article is devoted to the find of a bronze coin of Sauromates II, the ruler of the Bosporan Kingdom in the years AD 174/175–210/211, during archaeological research on the Przeworsk Culture settlement (site 2) in Trębaczów, Kazimierza Wielka district. The piece, a so-called »triple sestertius« or drachm, belongs to the second series of bronze coins of the king, dated ca. AD 186–196 (Zograph 1951; Frolova 1997a) or ca. AD 180–192 (Anokhin 1986). It adds to a small group of finds of Bosporan coins minted from the second half of the 1st century BC until the 4th century AD made in the territory of today’s Poland. Previously, six such finds were known. The newly discovered specimen probably found its way to the settlement of the Przeworsk culture in the first half, or the early years of the second half, of the third century AD as a result of contacts among different groups of people living in the Eastern and Central European Barbaricum
