River runoff forecasting is one of the most complex areas of research in hydrology because of the uncertainty of hydrological and meteorological parameters and scarcity of adequate records. Artificial neural networks (ANN) can be an efficient way of modelling stream flow processes as it is capable of controlling and modelling nonlinear and complex systems and does not require describing the complex nature of the hydrological processes. In this study, daily river flow is forecasted using two ANN ...

The implication of this is that water must be treated as an economic good, which means that the "user's pays' principle"has to be implemented. At the same time there is much political consensus that the water price has to be "equitable". Water can be subsidized without violating the ...

Abstract The olive mill wastewater (OMW) is a stable emulsion composed by water, olive pulp and residual oil. An approach for using this waste as a renewable resource is of greater interest. Several authors have been studding physicochemical treatment methods. However, the biological treatments allow not only the treatment, but also the effluent valorization, by producing several valuable products. This effluent is also a source of natural antioxidants and its extraction is economically attra...

Abstract The aim of this work was the evaluation of the denitrification potential of a consortium of activated sludge adapted to anoxic conditions. As the carbon source is the main parameter influencing the denitrification process, in the first stage three carbon sources (acetate, citrate and glucose) were assayed in batch activity tests. The highest denitrification efficiency was ttained with acetate, being nitrate and nitrite completely reduced. The adapted sludge was then used as a potent...

Chromium and cadmium are heavy metals that occur naturally in the environment and especially in soils. Their toxic effect is more pronounced at high concentrations and it depends on the oxidation states. While Cr (III) is considered an essential trace element for the metabolism of living organisms, Cr (VI) has a higher mobility and is easily soluble in soils and can be leached into surface water or groundwater, and taken up by plants. That leads to a toxic and carcinogenic effect to humans via i...

High contents of colloidal and organic materials in municipal wastewater sludge cause problems in the process of dewatering. The filtering efficiency can be improved by chemical conditioning, but the effectiveness of mechanical dewatering is limited because flocculated sludge is highly compressible. Physical conditioners such as bagasse can be used to facilitate mechanical dewatering. This paper describes the use of bagasse pith (cane sugar waste fiber) to improve the dewatering process of mu...

A mine ventilation system provides a fresh air flow to the underground workings in a coal mine. Such sufficient air volume can dilute and remove noxious gases (typically NOx, SO2, CH4, CO2 and CO) and maintain a suitable working environment for coal miners. On the other hand, a poor ventilation system often leads to serious consequences such as mine gas explosions, production loss or higher operational costs. Hence, the functions of mine ventilation system are very important for an undergroun...
