The natural zeolite from Evros prefecture contains Ca-rich clinoptilolite (89 wt.%) and in total 92 wt.% microporous minerals (zeolite + mica + clays). Quartz and feldspars constitute the non-microporous minerals (8 wt.%). Acidic water (pH 5.5) from the Kokkinolakkas Stream and basic water (pH 9.5)

Energy statistics may have resulted in different projections, indications, and estimates of the growth in world primary energy demand. But all agreed upon the fact that the increase in demand for energy is inevitable. Of course the growth rate varies in different regions of the world and depends on

A lot of small and shallow bays that exist along the extended Greek coastline differ significantly from the open sea in the fluctuation of hydrological parameters, the degree of eutrophication and the concentration of pollutants. These characteristics can sometimes create environmental conditions th

The Potpec reservoir is situated in the southwest of Serbia. It has been formed in 1977 on the Lim river and used for the electric energy production. In this paper, the results of the qualitative and quantitative analysis of zooplankton, as well as saprobiological analysis of plankton community, are

Data are presented on a study carried out on water analyzed with three different methods. Thus, a comparison was performed in parallel with the ISO 9308-1 reference method, stated by the European Drinking Water Directive, and two enzyme-based methods, the Colilert 18/Quanti-Tray™ and the Chromogenic

Chilled water air-conditioning systems are the lifelines of cooling for large commercial, industrial and public buildings. The aim of this paper is to examine and evaluate damages sustained to a large hotel in Greece. The damage that discovered concerns corrosion and salt deposition problems of a ch

In the present study, the physicochemical and microbiological characteristics of the potable water in the prefecture of Kozani are studied, according to the results of the analysis carried out in the Environmental Centre Laboratory, during 2002–2005. According to the Greek Legislation and the EU Dir

Solar evaporators are widely used in salt mining from seawaters or saline waters. The potash industry in Jordan and other countries utilized solar energy in the evaporation process to concentrate seawater where salt starts to deposit. In this work, the thermal performance of such evaporators was ana

The innovative and evolutionary principles of Water Framework Directive (2000/60/EC) towards the “good” ecological status of the water bodies, comprise a burdensome issue for most of the member states in European Union. In particular, the European Water Supply and Sewerage companies which are in a m

Textile industry is one of the most common and essential sectors in the world. On the other hand, high volume of water consumption and varying wastewater characteristics due to many products such as dyes, biocides, carriers, detergents, etc. used in the process are the factors that have caused a con
