Pozzolanic material and a chemical admixture have been used in the current investigation; Nano Biomass Silica (NBS) and Poly-Carboxylate Ether (PCE). NBS produces 20% of the 590 million tonnes of paddy produced globally. Amorphous silica, a mineral component used in concrete, is present in sizable...

Air is one of the most basic and important elements for human beings to survive. Clean and Sound air is the key to a good and healthy life. But nowadays in city life it has become the most threatening factor. Pollution of air has become the most concerning and affected issue now for us. As time goes...

In the present work a new freely available web-based tool is developed within Google Earth Engine (GEE) that aims to support water agencies, farmers and public services acquire information on the water budget components in the areas of their interest. The tool makes use of the high-resolution land...

Contaminants of emerging concern (CECs), such as pharmaceuticals and personal care products (PPCPs) and as endocrine disrupting compounds, have recently recognized as the next set of pollutants due to their toxic effects on human health and aquatic organisms at very low concentrations. One of...

The textile industry has an important place in the environmental pollution due to its heavy water consumption and to the toxic content of dye. Every succeeding day, the water quality is deteriorated because the wastewater containing the dye is supplied to the receiving medium. In this study, The...

The growing expectations of the population and the increasingly stringent regulations about air pollution have resulted in the need to minimize and conveniently treat the waste gas from different emission sources. The emissions from a large variety of plants, including waste and wastewater treatment...

For any river basin management, one needs tools to predict runoff at different time and spatial resolutions. Hydrological models are tools which account for the storage, flow of water and water balance in a watershed, which include exchanges of water and energy within the earth, atmosphere and...

The scientific community has recognized the necessity for more efficiently selected inputs in artificial neural network models (ANNs) in river flows and has worked on this despite some shortcomings. Moreover, there is none or limited inclusion of ANN inputs coupled with atmospheric circulation under...

This study aims to model the dispersion of two pollutants: nitrogen oxides (NO x) and sulfur dioxide (SO 2) from an onsite biogas fueled generator by using CALPUFF modeling system. CALPUFF is a non-steady state puff simulating software that takes into account, meteorological data, terrain data and...

Current study was carried out to investigate the heavy metals removal from landfill leachate and urban wastewater by powdered activated carbon and powdered zeolite augmented SBR technique. The research was carried out in six 2000 mL breakers (working size was 1200 ml). The reactors were parted into...

Designed experiments are used to systematically examine the relationship between response variable and a set of experimental factors. In this study, 2 3 factorial design with center points was used to verify the selected experimental factors influence the removal efficiency and linearity assumption...

In this study, a four-factor five-level Central Composite Design (CCD) was applied to develop mathematical model and optimize process parameters for malachite green dye (MG) removal from aqueous solutions using sepiolite. The individual, combined, and quadratic effects of four experimental factors...

Floods are natural disasters that pose a direct threat to human life and often cause significant economic loss. River floods are caused by heavy and/or prolonged rainfall, causing rivers and streams to overflow and sometimes also burst dams or levees. Forest fires increase the risk factor to which...

The purpose of the present work was to study experimentally the indoor air quality status regarding PM10, PM2.5, TVOCs, CO2, NOx, SO2 and O3 in selected differently used areas. A flat on the third floor of a multi-storey building, located at a suburban area north-east of the centre of Athens and...

This study reports particulate matter levels of various size fractions (PM10, PM2.5, and PM1) and identify their controlling factors, in various locations over Greece. It combines long-term data sets involving particle concentrations as measured in the island of Crete in the Eastern Mediterranean...

In the present study, the wet oxidation of zinc and copper cyanide complexes (cyanide concentration of 1,000 mg dm-3) was conducted in a hydrothermal reactor, under oxygen atmosphere of which the pressure was set to 1 MPa. The pH of the reaction solution was kept in the range of 11 to 12 and the...

The main objective of this research was to predict expected methane generation in Hellenic sanitary landfills, in order to evaluate its potential for energy production and to ensure health and safety in and around these sites on the long term. The study was performed for the period 2008 – 2028 with...

Coal fly ashes and metallurgical slags are currently widely used as supplementary cementitious materials in production of Portland cement-based concretes. However, this application makes very poor use of the intrinsic reactivity of the glassy phases present in the waste materials, and can hardly...
