The Korissia lagoon is located in the southwest of Corfu Island, Greece. It is a shallow coastal ecosystem of great aesthetic and ecological importance, included in the Natura 2000 network of protected areas. The lagoon is connected to the sea by an artificial channel and its depth varies between 0.

The present work is a comprehensive evaluation of drinking water quality from various regions of Greece. The physicochemical parameters investigated were conductivity, total dissolved solids and pH, as well as related to the treatment of drinking water such as chloride, potassium, calcium, magnesium

The process of coagulation is a fundamental environmental protection technology, which is mainly used in the treatment of water and wastewater. The relevant research is currently focused on the development of new improved coagulation reagents. A characteristic example is polyferric silicate sulphate

Zeolites are naturally occurring minerals characterized by high cation exchange and adsorption capacity and, thus, are used for metal uptake from sewage sludge subjected to composting process. In the present paper, changes in the physicochemical characteristics of sewage sludge samples after compost

The aim of this work was the assessment of the toxicity of various industrial effluents by a battery of bioassays in order to investigate their potential impact during co-treatment of industrial and municipal wastewaters in an activated sludge plant. The battery test included three test-species as i

An ion chromatography method with post-column reaction and optical detection, according to EPA Method 326.0, for the determination of bromate has been developed and validated in water samples. Optimization of reaction and operating conditions (post-column reagent and sulphuric acid regenerant flow r

The city of Malgara in the municipality of Aksios, in northern Greece, relies on local groundwater for the municipal water supply. The groundwater has pH 7.9 and contains elevated concentrations of arsenic (20 µg/L), phosphate (550 µg/L), manganese (235 µg/L) and ammonium (1.2 mg/L), whereas the iro

Physicochemical parameters, natural radioactivity and heavy metals on the surface waters of rivers in Epirus (Aoos, Kalamas, Louros), Macedonia (Aliakmonas) and Thessalia (Pinios) were measured during the period May 2004–May 2006 in three sampling sites of each river. All the determined metal concen

Clinoptilolite, a natural zeolite, was used for the synthesis of a high surface area clinoptilolite-iron oxide system (Clin–Fe system) to be used for the removal of Mn2+ and Zn2+ ions from drinking water samples. The new system was obtained by adding natural clinoptilolite to an iron nitrate solutio

Most of chemical reactions have — as a final result — a large mixture of end products out of which the main one represents a small rate when compared with secondary products. One of these reactions results in a mixture of products that takes place in the process obtaining ethylene amines. The reacti
