Iron oxide materials were synthesized by an easy and rapid hydrothermal method using different iron precursors (FeCl 3∙6H 2O, Fe(NO 3) 3∙9H 2O and K 4Fe(CN) 6∙3H 2O), solution pHs (acid and basic) and reaction times (3 h and 6 h). The synthesized materials were thoroughly characterized by...

The photocatalytic degradation of caffeine has been investigated in aqueous suspensions of titanium dioxide (TiO 2) by monitoring process efficiency at varying TiO 2 (25 - 175 mg l -1) and initial drug concentrations (0.5 - 9.5 mg l -1). The use of the response surface methodology (RSM) allowed to...

In this paper soil conventional tillage (CT) in two adiacent on-farm sites, hilly and plain fields, was carried out in comparison with direct-seeding + fertilizing at very low water content. The quality and quantity of work were evaluated through machine performance, fossil-fuel energy requirements...

Presence of antibiotics in the environment specially in aqueous environments is considered a major warning about health and environment. Thus, this study aims the efficiency of coupled process of Activated Carbon (AC) prepared from mango seed+ZnO under UV irradiation as an advanced oxidation process...

Irrigation water use is the major pressure limiting the availability of fresh water resources in the Mediterranean. Efficient irrigation scheduling programs (IRSPs) are able to reduce water consumption; however, their selection and placement in large agricultural landscapes depend on location...

In this paper the results of a preliminary study that investigates water footprint (WF) concept, as a useful tool to address water management problems in cultivated areas are presented. The two basic methodologies reported in the literature, their applicability, benefits and challenges were...

Calibration of rainfall-runoff models is made complicated by uncertainties in data, and by the arbitrary emphasis placed on various magnitudes of the model residuals by most traditional measures of fit. Current research highlights the importance of driving model identification by assimilating...

This paper is focussed on the study of the air movement and temperature distribution inside refrigerating compartment of household frost-free refrigerators. It is well known that the correct air circulation and temperature distribution inside the refrigerated chamber are two of the most important...

Wind energy offers significant potential for greenhouse gas emissions reductions. Most applications have been developed onshore but the planning and siting conflicts with other land uses have created considerable interest and motivated research to offshore wind energy establishments. In this paper...

This study aimed to evaluate the sorption capability of an inexpensive and easily available Moroccan clay, called locally Ghassoul, to remove Rhodamine B (Rh-B) from aqueous solution. Experimental results showed that the equilibrium sorption data fitted well with the Langmuir isotherm and the...

The wastewater generated by the textile industry is rated as the most polluting among all industrial sectors considering both volumes discharged and effluent composition. Present investigation intended for COD and color removal from textile wastewater using naturally prepared coagulants i.e. Surjana...

In this study, the development of a numerical model simulating surface drip irrigation from equidistant line sources in stratified soils under various conditions is being presented. The developed numerical model was used to investigate the effects of hysteresis, discharge rate, and soil hydraulic...

In this study, the effects of seepage flow in the swash zone on beach profile evolution under the wave action are examined numerically. The seepage flow is induced artificially by a porous drain pipe buried beneath swash zone parallel to the coastline. The system includes minimal environmental...

The performance of a laboratory scale electrocoagulation system for the removal of Cr and Ni from model wastewater was studied systematically using iron and aluminum electrodes with an effective surface area of 13.8 cm2 and a distance of 4 cm. The influence of several parameters, such as initial...

Improving the treatment efficiency of a primary wastewater treatment plant(WWTP),in Alexandria, Egypt,was studied.In order to improve the treatment efficiency of the plant, different improving scenarios were proposed and evaluated. The improvement scenarios are: scenario 1,use of engineered wetland...

Solar assisted Photo Fenton was compared with advanced oxidation processes for their color and COD removal efficiency and cost effectiveness. H2O2 alone appeared to be inefficient to reduce color and COD content of any effluent. The performance of Fenton process was slightly better, color and COD...

In the present study, the photocatalytic treatment of two synthetic textile dyehouse effluents was investigated. The first synthetic effluent (SE1) is a Remazol Black B aqueous solution, while the second one (SE2) is an aqueous mixture of sixteen dyes and auxiliary chemicals that are usually...

Many studies have been conducted to increase the efficiency of hydrogen peroxide (HP) in wastewater disinfection to make HP disinfection more cost-effective with respect to reduced concentration and detention time. In this study, the effects of HP, copper ions (Cu2+), and 1 atm. pressure-dissolved...

Groundwater in the area of eastern Croatia contains increased concentrations of organic compounds, primarily natural organic matter (NOM). Organic compounds in water become a problem in drinking water treatment, especially during water disinfection with chlorine, when harmful disinfection by...
