In this paper, the pollutant removal efficiency and reliability of a vertical horizontal flow hybrid constructed wetland (CW) planted with common reed, manna grass, Virginia mallow were analyzed. The wastewater treatment plant, located in south-eastern Poland, treated domestic sewage at an average rate 2.5 m3/d. tests carried out during five years its operation (2014–2018). following parameters measured: biochemical oxygen demand (BOD5), chemical (COD), total suspended solids, nitrogen,...

A thorough evaluation of measurement uncertainty together with control short-term and long-term precision measurements should be a basis any successful quality assurance/quality (QA/QC) strategy aimed at maintaining high the analytical process. Here we present results comprehensive assessment performance Picarro L2140-i CRDS laser spectrometer analysing δ2H, δ18O δ17O in water. The is based on obtained during 15 months continuous operation this instrument (February 2017 to May 2018)....

Abstract The reliability of removal selected contaminants in three technological solutions the household sewage treatment plants was analysed this paper. plant with activated sludge, sprinkled biological deposit and hybrid reactor (activated sludge immersed trickling filter) analyzed. analysis performed using Weibull method for basic indicators impurities, BOD 5 , COD total suspended solids. active 70% 87% 66% In a deposit, values determined were: 30% (BOD ), 60% (COD) 67% (total solids)....

The paper presents the results of a 3-year study on technological reliability and efficiency typical domestic wastewater treatment in two hybrid constructed wetland systems (CWs) located area Roztocze National Park (Poland). studied objects consist an initial settling tank system beds vertical flow (VF) horizontal (HF) (VF–HF) type with reed willow. rate wetlands was 0.4 1.0 m3/d, respectively. During period (2017–2019) 20 series analyses were performed 60 samples collected. Based obtained...

The aim of the work is to present current state water and wastewater management in municipalities where Polesie National Park (PNP) located.The PNP situated Lublin Voivodeship, area six municipalities: Sosnowica, Hańsk, Urszulin, Stary Brus, Wierzbica Ludwin.The data used this paper, were obtained on basis surveys conducted these 2016 by Department Environmental Engineering Geodesy University Life Sciences Lublin.In analyzed communes, there was a very large disproportion between usage...

The present paper reports pollutant removal efficiencies and reliability for a four-stage hybrid constructed wetland (HCW) consisting of the following sequence subsurface (SS), vertical flow (VF) horizontal (HF) beds: SSVF-SSHF-SSHF-SSVF. experiments were carried out over period three years, with sampling done in each season: winter, spring, summer autumn. Grab samples wastewater collected from different stages treatment tested total suspended solids (TSS), BOD5, COD, nitrogen (TN)...

This study presents the efficiency of TSS and organic pollutants (BOD5 COD) removal in a hybrid constructed wetland wastewater treatment plant (VF-HF type) with an aeration system. was conducted over 6 years (2017–2022) facility capacity 4.5 m3/day located southeastern Poland designed to treat real domestic from school building. The studied consists three-chambered septic tank, pumping station system, two beds vertical horizontal flow planted giant miscanthus willow. As result artificial...

Abstract Isotopic composition of precipitation ( 2 H /1 and 18 O/ 16 O isotope ratios, tritium content) is nowadays widely used in numerous applications environmental isotopes—most notably hydrology, climatology biogeochemistry. Here we present a long record (44 years) stable content monthly available for the Krakow station (southern Poland). only site Poland which long-term isotopic available. The data are discussed here context generally declining levels bomb global atmosphere growing...

The results of research on the efficiency and technological reliability domestic wastewater purification in two household treatment plants (WWTPs) with activated sludge are presented this paper. studied facilities were located territory Roztocze National Park (Poland). mean flow rate WWTPs was 1.0 1.6 m3/day. In 2017–2019, 20 series analyses done, 40 samples taken. On basis received results, basic pollutant removal determined. tested specified using Weibull method. average efficiencies for...

Abstract The study investigated the efficiency of removal iron, manganese and indicator bacteria from potable groundwater by using carbonate-silica rock (opoka). tests were performed in a laboratory three filter columns supplied with water containing increased concentrations iron manganese. Two filled particle sizes 2-5 mm; retention time for was set at 1 h 2 h. A third column 1-2 mm particles, hydraulic High efficiencies determined coliform low psychro- mesophilic bacteria. An increase...

The aim of this paper is to present the current state water and sewage management in communes where Roztocze National Park (RNP) located.The park located Lubelskie voivodship, territory four communes: Zamość, Zwierzyniec, Adamów Józefów, while its buffer zone Krasnobród, Tereszpol Szczebrzeszyn.The uses data from surveys conducted these municipalities 2016.On average, 68.9% population used supply system surveyed, 33.4% inhabitants had possibility discharging sewerage system.In area communes,...
