A combination of non-parametric explanatory procedures and pattern recognition techniques is introduced in this study as an alternative tool to the assessment of sedimentary P fractionation. The complex raw data matrix was treated with a series of parametric and non-parametric techniques such as cor

Different category-wastewater samples were collected from the inlets of biological treatment plants (installed in hospitals, industries and municipality) and from the body of polluted natural surface water (PNSW) systems (lakes, rivers). UV absorption spectral data of each wastewater system or their

Activated sludge bulking caused by filamentous bacteria Eikelboom type 021N and Thiothrix spp. is reported for the first time in a multistage pilot-scale wastewater treatment plant for enhanced biological phosphorus removal (EBPR). Both types of microorganisms grew gradually reaching their maximum c

Efficient software was used for the comparison of five alternative scenarios for the treatment of cheese whey wastewater resulting from a Cheddar cheese factory. Scenario 1 deals with a cheese whey wastewater treatment plant that produces butter, whey protein concentrate and food-grade ethanol. In s

The possibility of complete fractionation of olive mill wastewater (OMW) was investigated using membrane technology. Combinations of different membrane processes were used for the fractionation of OMW into by-products that may be further developed to achieve reduction of the expenses involved. Ultra

In the present study the involvement of human activities is assessed in the revalorization of groundwater quality. The groundwater quality was assessed on the basis of physical and chemical analysis (electric conductivity, pH, − − total dissolved solids (TDS), total hardness, NO−, NO2 , SO4 2, Fe, M

The rapid and almost uncontrolled growth of population has a result a continuously increasing water demand in agriculture needs, industrial uses and domestic services. This has a dramatic impact on the available water resources and at the same time put the basic infrastructure facilities under sever

Various countries in the Mediterranean Basin and other arid and semi-arid regions are confronting water shortage issues. This gap between supply and demand is closely linked with agricultural production, environmental conditions, and climate changes. It is also probably due to reduced amounts of pre

Greece and Bulgaria, are crossed by three very important transboundary rivers, namely Strouma, Nestos/ Mesta, and Maritsa. However, until recently no effective plan concerning their Integrated Water Management has been made. This is rather justified because an Integrated Water Management must be bas

The Axios/Vardar River, an interboundary river located in the Balkan Peninsula, drains the region of southern Serbia, almost 80% of the Former Yugoslav Republic of Macedonia territory and some parts of northern Greece. This study is based upon long-term data (1979–2003) of nitrate, nitrite, ammonium
