Iron is a chemical element that found in almost every place on earth, including well water or groundwater. can be suspended with organic substances inorganic solids the form of ferrous cations (Fe2+) and ferries (Fe3+). The presence iron exceeds threshold cause detrimental effects such as corrosion piping, color turns brown, smells bad, health problems. content groundwater reduced so it used fi...

Abstract Electrocoagulation technique using aluminum electrodes in a batch bi-polar system was investigated to determine the efficiency of removing oil from oily wastewater. The Box–Behnken design utilized optimize conditions and effects four independent factors, including volume ( X 1 ), temperature 2 initial pH 3 treatment time 4 ),—were examined investigate turbidity recovery conductivity ch...

This study investigated the feasibility of using near infrared hyperspectral imaging (NIR-HSI) technique for non-destructive identification of sesame oil. Hyperspectral images of four varieties of sesame oil were obtained in the spectral region of 874-1734 nm. Reflectance values were extracted from each region of interest (ROI) of each sample. Competitive adaptive reweighted sampling (CARS), su...

increased trend toward the use of advanced medical imaging for the diagnosis and assessment of SpondyloArthritis (SpA) (1, 2). MRI of the sacro-iliac (SI) joints has become a key-imaging technique for the detection of early non-radiographic axial SpA and has been shown to contribute to optimized clinical decisionmaking (3). The current paper aims at summarizing recent advances in the understand...

INTRODUCTION Over the last decade, laparoscopic splenectomy has become the standard of care for spleen removal. Elimination of a large incision and difficult exposure has decreased postoperative morbidity and length of stay. Single port access (SPA) surgery was developed as an alternative to traditional multiport laparoscopy, potentially exploiting the already proven benefits of minimally invas...

Synthetic oily wastewaters were prepared from metal working fluids (MWF). Electrocoagulation experiments were performed under constant voltage application. The current, conductivity, pH, dissolved oxygen concentration and temperature were recorded on line at every 5 seconds during the experiments. Effects of applied voltage differences, electrode materials and distance between electrodes on rem...

Coagulation and flocculation are traditional methods for the treatment of polluted water. Electrocoagulation presents a robust novel and innovative alternative in which a sacrificial metal anode doses water electrochemically. This has the major advantage of providing active cations required for coagulation, without increasing the salinity of the water. Electrocoagulation is a complex process wi...

In this work, the performance of electrocoagulation with aluminum electrodes for simultaneous removal of nickel, copper, zinc and chromium from synthetic aqueous aliquot solutions and actual electroplating wastewater was studied. Parameters affecting the electrocoagulation process, such as initial pH, current density, initial metal ion concentration, COD and contact time were investigated. Best...

background: electrocoagulation is a technique involving the electrolytic addition of coagulating metal ions directly from sacrificial electrodes. these ions coagulate with turbidity agents in the water, in a similar manner to the addition of coagulating chemicals such as alum and ferric chloride, and allow the easier removal of the pollutants. purpose of this study was to conduct experimental i...

Electrocoagulation was used for dechlorophyllation of alcoholic extracts from five plants. The results showed that for every plant extract studied, electrocoagulation was more efficient than the classical solvent extraction method in removing plant pigments, while not affecting the important secondary metabolites in those extracts.
