Abstract: This work consists of assessing the degree of pollution caused by wastewater, Power station discharge pipe and petroleum port in the gulf of Tobruk-Libya. This study is based on the analysis of the physicochemical parameters, the parameters indicating pollution and the determination of pH, DO, BOD, OOM, phenol, Salinity, nutrients (PO4, SiO3, NO2, NO3 and NH3), sodium and potassium on seawater samples taken from the site. The sampling was carried out during the April of year 2015. The results obtained show significant values in physicochemical parameters, pollution indicator parameters. The results of the pollution indicator parameters show the presence of important pollution at the site studied. It is clear from the determination of physicochemical parameters that the site under investigation shows a high contamination of seawater according to pollution caused by wastewater, Power station discharge pipe and petroleum port near the gulf of Tobruk-Libya. The absence of treatment and the long-term exposure to these discharges will lead to dangerous levels which maybe lead to destruction of marine life may affect people living near the port.

Abstract: The adsorption behaviour of an azodye Methylene Blue (MB) over aluminum oxide nano particles (AONP) generated by sol-gel method has been studied to investigate the physicochemical process involved andexplore the potential use of AONP in wastewater treatment. The variables incorporated in the present study are concentration of dye, dosage of adsorbentand contact time. The characterizations of AONPs were carried out using X-ray diffractometry (XRD), Scanning Electron Microscopy (SEM), Fourier Transform Infrared Spectroscopy (FTIR), Energy Dispersive Analysis of X-rays (EDAX) and Raman spectroscopy. SEM image showed the distribution pattern of nanoparticles. FTIR spectra revealed thatfunctional groups (O-Al-O) are present. Raman spectra showed the crystalline nature of nanoparticles. Averagesize of Al2O3 nanoparticle from XRD peak was found to be 25 nm having rhombohedral structure. Chemical composition of AONPs was confirmed from EDAXspectroscopy measurement. The smaller dosage of AONP was tested for the photocatalytic degradation.

Abstract: The aim of this work is to study the removal of methyl orange (MO) using electrocoagulation (EC) process. An electrochemical cell consisting of two iron electrodes, with 22.5 cm2 as an active surface, is used. Operating conditions are optimized such as nature and concentration of the supporting electrolyte, current density, pH, inter-electrode distance, MO concentration, and the connection mode. The decolorization degree obtained after 15 min of EC reached 83% at pH 7.25 with a current density of 64 A/m2. Depending on pH, three EC process mechanisms are suggested and less or more significant removal performances are obtained in these tests. The Scanning Electron Microscopy (SEM) observations show that the flocs formed by the EC process have two distinct morphologies: a lumpy structure and an amorphous structure, formed by particles of various sizes. The Energy Disperses X-ray (EDX) analysis of the surface of the flocs formed by the EC process shows a spectrum with levels of major elements of iron, oxygen and chloride, as well as carbon, sodium and aluminum are detected as minor elements. As proved in terms of MO elimination through this research and due to its several advantageous, EC process would find its convenient place in wastewater treatment technology.
