Water specifications vary along the course of the river, which represents the main source of drinking water in Egypt, with depends on the treatment of raw freshwater by conventional plants to get rid of the main pollutants of freshwater, such as suspended particles (turbidity) and microorganisms, therefore assessment of the characteristics of freshwater of the river over long period and studying it opens many horizons for establishing of new techniques for treating the freshwater. The main objective of this study is to monitor the Nile River over a period at the study area Assiut-Egypt, as this study shows that the Nile River contains large quantities of bacteria with an average 1645 CFU/ml throughout the year in different seasons those affects the numbers of these bacteria, in addition to the river contains moderated concentrations 136 M.

The study aims to prepare a reasonable adsorbent composite from Egyptian organo-kaolinite and prepared chitosan to remove the excess of sulfate ions from Assiut groundwater wells. Therefore, the modified organo-kaolinite was treated with prepared modified chitosan as a composite media filtration to treat groundwater. In this study, the prepared chitosan was characterized by using X-ray diffraction (XRD). FTIR and scanning electron microscopy (SEM) and its efficiency for removing sulfate have been tested through batch and experimental column studies. The results revealed that the adsorption of sulfate ions is optimum at pH range 4–8. The maximum sulfate ions adsorption capacities were found 2.88 mg/g, after about 65 min contact time. The regeneration study illustrated that the prepared composite could be used up to 5 times with maximum sulfate ions percentage removal of 62.33%, achieved after the 5th cycle.

There are different types of APF according to its application. This paper will introduce a detailed design of a Shunt Active Power filter (SAPF). Firstly trial and error method will be used to select acceptable value for conventional filter PI controller parameters, Secondly particle swarm optimization (PSO) technique is used for tuning the filter PI controller by optimizing the optimal controller gains. The presented design is modeled and simulated by using MATLAB-SIMULINK toolbox. Many contributions such as design and simulation of SAPF, besides practical modeling of a nonlinear load for studying the effect of SAPF on the integrated system. A practical verification is done and compared to the proposed simulated system. It is found that a good agreement between the experimental result and the modeled one. A costless method based on Virtual experimental technique is also used and applied to large scale systems for obtaining predesign system with acceptable accuracy.

Their carcinogenic and toxic effects have been recorded on human being. Identification of the key microorganisms that play a role in pollutant degradation processes is relevant to the development of optimal in situ bioremediation strategies. In the current study, a bacterium strain designated as AUN-AS01 was isolated from wastewater of Assiut University hospitals by enrichment technique in mineral basal salts (MBS) medium supplemented with phenol as a sole carbon and energy source. The strain AUN-AS01 was identified using PCR amplification of 16S rRNA gene and sequence analysis. The comparison of the alignment results and phylogenetic analysis of the sequences of the isolated strain to published rRNA gene sequences in Gen Bank, confirmed the identification of the isolate as Paenibacillus mucilaginosus AUN-AS01.The strain was able to grow and had a tolerance of phenol concentration up to 1600 mg/L -1 . It was observed that temperature, pH and initial concentration of phenol play key roles in determining the rate of phenol degradation by the isolated strain AUNAS01. Results showed that, the strain was efficient in removing 92.26±0.05% of the initial 800 mg/l phenol within 48 h with optimal conditions, at 30 o C and had a pH of 7.0. Our results demonstrate that, strain Paenibacillus mucilaginosus AUN-AS01could be used to remove the phenol from the environment. These findings may lead to new 14 Ahmed Salah et al.

Brix is the amount of sucrose contents presents in the raw sugar solution. Degree Brix (symbol °Bx) measures the concentration of dissolved solids in the solution. One-degree Brix is 1 gram of sucrose in 100 grams of solution and represents the strength of the solution as percentage by mass. Based on the brix value in solution, the operators can measure and take decisions in sugar industrial process. The aim of the present paper is suggesting method to measure the brix value in a raw sugar solution using several electronic sensors that have been installed and connected to microcontroller to perform several calculations to calculate brix. This proposed method is a low price with high accuracy in reading Brix in raw sugar solutions in industrial processes. This method depends on the physical properties of the sugar solution. Electronic sensors can directly measure the mass, and temperature of the solution to express the brix and give the result on the screen. Also, the results can be sent directly to the central control room. Moreover, it can be used manually on the production line and in various food industries. The suggested method can be applied directly in the industrial process during extracting sugar such as juice and syrup to determine their 70 M. Elewa, et al.
