    Fenton Technology for Wastewater Treatment: Dares and Trends

    Djamel Ghernaout, Noureddine Elboughdiri, Saad Ghareba
    Fenton reaction remains an efficient technique for decomposing recalcitrant organic contaminants. Nevertheless, traditional Fenton response has many lim-itations like the necessity of acidic pH circumstance, the formation of iron sludge and the need for elevated chemical introductions. Procedures like het-erogeneous Fenton, fluidized-bed Fenton, employment of chelating products and in situ formations of Fenton’s reagent have been

    Is Not It Time to Stop Using Chlorine for Treating Water?

    Djamel Ghernaout, Noureddine Elboughdiri
    Chlorine is largely used as a disinfectant in the water and wastewater treatment industries through the world despite the fact that is greatly poisonous for hu-man beings. Its toxicity is more extended to generating disinfection by-products during its microorganisms’ killing and action on organic matter present in water. More importantly, recent studies proved the potential impacts of disinfection on transmission of antibiotic res

    Electrochemical Technology for Wastewater Treatment: Dares and Trends

    Djamel Ghernaout, Noureddine Elboughdiri
    For treating wastewater, electrochemical engineering has been rediscovered during the last four decades through the world for its inherent advantages comparatively with traditional technologies especially the chemical and biological techniques. However, the expansion of this technology founded on electric current applying has been retarded by several technical-economic factors especially the detection of disinfection by-products (

    Water Reuse: Emerging Contaminants Elimination—Progress and Trends

    Djamel Ghernaout, Noureddine Elboughdiri
    This work concentrates on the review paper published by Ahmed et al. [1] which is dedicated to the elimination of emerging contaminants (ECs) using biological, chemical and hybrid techniques in effluents from wastewater treatment plants (WWTPs). Endocrine disruption chemicals (EDCs) are better reduced by a membrane bioreactor (MBR), activated sludge, and aeration processes between various biological processes. Surfactants, EDCs an

    Direct Potable Reuse: The Singapore NEWater Project as a Role Model

    Djamel Ghernaout, Noureddine Elboughdiri, Abdulaziz Alghamdi
    In Singapore, indirect potable water reuse has been applied during the last two decades. Now, water reuse furnishes around 30% of the nation’s water request and the well-known NEWater success story has greatly participated in transforming Singapore into a global hydro hub for pioneering novel water techniques. This work discusses the recent technological improvements and the outlooks for water reuse in Singapore as a model. Fields

    Influence of Polythene Bag Alternatives on Compliance to Environmental Legislation on Polythene Bag Ban in Rongai Sub-County, Nakuru County, Kenya

    Victor Kipkemboi Koros, Jackson John Kitetu, Sella J. Kebenei
    Polythene bags have been preferred for packaging purposes because they are light in weight, cheap and resistant to degradation. Despite the benefits, poor disposal of polythene causes degradation and pollution of soil, water, land and air resources leading to health problems and climate change. Furthermore, pol-ythene kills the wild game, livestock and aquatic organisms. These problems have led to the intro

    Trace Metals in Groundwater of Kumba and Environs in Cameroon

    Richard Ayuk II Akoachere, Thomson Areakpoh Eyong, Marcelle-Carole Pami Ngassam, Raymond Ndip Nkongho, Simon Oko Okpara
    Kumba and environs situate between longitudes 9.24E - 9.5E and latitudes 4.44N - 4.7N, is the economic capital of the Southwest Region-Cameroon. It is located along the Cameroon Line at northwestern edge of the Douala Basin. The inhabitants depend mostly on groundwater through springs, handdug wells and boreholes. In this area like in most of Cameroon and Africa, water from groundwater sources (springs, wells and boreholes) is not

    Assessment of Tree Diversity and Abundance in Selected Forest Reserves in Osun State, Southwestern Nigeria

    Janet Temitope Asifat, Oyetayo Oyelowo, Oluwagbemiga Oluwapamilerin Isaac Orimoogunje
    Studies have shown that forest has undergone different levels of disturbance due to anthropogenic activities which impacted tree diversity, abundance and species composition. Therefore, this study examined and assessed tree diversity and abundance in five selected forest reserves in Osun State, Nigeria with a view to ascertaining the present species status for mitigation decision. Primary data include measurement of floristic comp

    Evaluation of Trace Metals in Groundwater of Ekondo-Titi and Environs, Onshore Rio Del Rey, Cameroun

    Richard Ayuk II Akoachere, Thomson Areakpoh Eyong, Marcelle-Carole Pami Ngassam, Raymond Ndip Nkongho, Simon Oko Okpara, Tom Tabi Oben
    Barium is the most enriched element in the study area; this could be attributed to agricultural fertilizers. Igeo values indicate groundwater is no pollution to moderately pollution risk from Li, V, Cr, Co, As, Cd, Pb while groundwater has a strong pollution risk from Ba and extreme pollution risk from Mn, Sr, Fe and Zn, though the concentrations of the trace metals are below WHO guidelines. Thus, from the health hazard indices and pollution risk indices on trace metals, the groundwater in Ekond...
