    Abstract: Central composite rotatable design experiment is used to study the effect of coagulation process for acid dye effluents and to optimise the variables such as dye concentration, coagulant dosage and initial pH, which influence the efficiency of colour and COD removal of dye effluents. The steel industrial wastewater (SIWW) FeCl3 rich is used for thi... Show More

    Abstract: Sambayourou is one of the main tributary of Mouhoun River in southwest Burkina Faso. Its watershed is part of area affected by mining operations from Poura gold mine in 80s. Investigations on surface water, ground-water and soil from Sambayourou watershed reveal that enormous volume of mine wastes from Poura old gold mine is causing acid mine drain... Show More

    Abstract: The aim of this work was to study the mineralization of hydrocarbons during composting. For this purpose, soil/green waste mixtures were prepared at three different ratios (S/GW= 60/40, 70/30, 80/20) composted for 90 days. An unamended polluted soil (100% soil) was used as the control. The results indicate that the composting process greatly increa... Show More

    Abstract: Due to health concerns of natural organic matter (NOM) and algae presence in surface water and difficulties encountered in their removal in the water treatment, this paper reviews coagulation and chlorination processes which are largely used in water treatment technology. In the conventional water treatment, coagulation and slow filtration treatmen... Show More

    Abstract: The inhibitory effect of heavy metals in nitrification has not been extensively investigated although it is expected that some form of inhibition would show up in the presence of these. Since Cadmium is a common heavy metal present in industrial effluents, its effect on nitrification has yet to be evaluated in qualitative and quantitative terms. In... Show More

    Abstract: In order to determine copper removal efficiency and compartmentalization in the free floating fern S. minima, a bioassay was performed in which plants were exposed to increasing copper concentrations in the range of 1 to 30 mg Cu L-1 for six days in Pilcomayo River surface water. S. minima accumulated the metal in a dose-dependent manner. Metal con... Show More

    Abstract: The ability of calcined limpet shells (CLS), to remove Cu(II) and Zn(II) from effluent solution by biosorption has been studied. All the studies were conducted by a batch method to determine equilibrium and kinetic studies. The effects of contact time, CLS dose, pH and temperature were studied for the biosorption of Cu(II) and Zn(II) on CLS. Biosor... Show More
