Bacteria from the family Enterobacteriaceae in reused water and their antibiotic susceptibility

The aim of this study is to evaluate the presence of bacteria from the Enterobacteriaceae family (i.e. total coliforms, thermotolerant coliforms and Escherichia coli) in different types of recycled waters (grey water, rain water and reclaimed water from the public city fountains) and problems with their detection (especially ensitivity and specificity of detection methods). The species composition of coliform bacteria in purified grey waters with their antibiotic resistance are presented.

River ferries on old topographic maps

Medium and large rivers have been a major obstacle to historic trade routes and trails. River ferries were one of the main ways to cross them, so their locations were considered points of strategic importance. Using old topographic
maps of Austrian military mapping from 1763–1768, 1836–1852, 1876–1880, Prussian military maps from 1825 and 1877 and Czechoslovak military maps from 1953–1957, we systematically located ferries throughout the current territory of the Czechia.

Atmospheric deposition as a possible source of surface water pollution (Preliminary results of the project, part 1 – heavy metals)

Concentrations of selected heavy metals in collected atmospheric precipitation
and surface water were monitored at pilot sites in the Jizera Mountains, the Moravian‑Silesian
Beskydy Mountains and the Bohemian‑Moravian Uplands (CZ) over the course of one year to determine the significance of the impact of precipitation on surface water quality in an otherwise relatively low anthropogenically influenced environment. The measurements show that for some
metals, atmospheric deposition in heavily loaded areas can cause significant inputs to streams and reservoirs, but the resulting balance is strongly influenced by the environment and its past loading.

Food waste issues in relation to the mandatory reporting of its production for the needs of the Waste Framework Directive

From this year, the European Union member states are obliged to introduce preventive measures that will reduce the amount of food waste at all stages of the food chain. The presented paper deals with this current topic, presents possible procedures for obtaining data on food waste production at various stages of the food chain and shows the results of our own research and analysis
about the usability of these data for reporting obligations and demonstrating
future reductions.

A review article of Rapid Small-Scale Column Tests

Rapid Small‑Scale Column Tests (RSSCTs) can be used for quick and easy laboratory verification of adsorption efficiencies on various adsorbents. The selection of adsorbent is the most important aspect when incorporating adsorption technology into the operation of the drinking water purification plant, or the wastewater treatment plant. The tests are carried out on laboratory‑scale, which minimizes material and operating costs. The article focuses on the adsorption on granular activated carbon (GAC), as it is the most commonly used type of adsorbent.

Citation analysis of VTEI

The citation rate of a journal is considered an indicator of the quality of the journal.
In this study, the citation analysis of the VTEI journal is presented. The citation
analysis was conducted to identify the countries and institutions of authors
who cite articles published in VTEI and the subject areas in which articles published
in VTEI are cited.

Risk assessment as a comprehensive approach to protection of drinking water sources

Drinking water supply as well as its quality form one of the basic pillars of modern society. This corresponds to the goal of the International Water Association (IWA) – good, safe and drinkable water, which enjoys consumer confidence and can be not only drunk without fear, but in which the consumer also appreciates its taste and… Read more »
