Read More This paper assesses the environmental impact of the wastewater treatment plant (WWTP) of the Cameroon Real Estate Company (CRE) camp in the "Cité-Verte" district in Yaoundé (Cameroon) and the causes of its malfunction. The study was carried out in two stages. The first stage consisted of describing the wastewater treatment steps of the WWTP, and analyzing the staff interviews in order to determine the causes of malfunction that had been suspected. The second phase consisted of collecting water samples at the entry of the WWTP (P1), inside the WWTP (P2), and at the outlet of the WWTP (P3). This, in order to produce a list of the WWTP's collecting systems, characterize the various types of wastewater (P1 and P2) and the treated wastewater (P3), and then determine the effect of effluent discharges on the environment. Finally, the structural and operational malfunctions of WWTP are identified using the Ishikawa and the Pareto diagrams. The results of water characterization show that the mean values of pH (7.7), EC (1059.3 μS/cm), TDS (524.6 mg/L), T° (23.6 °C), BOD5 (10.8 mg/LO2), NO3- (2.3 mg/L), and fecal coliforms (447.3 CFU/100 mL) are below the acceptable limit values of the Cameroonian standard of treated wastewater discharge. However, the mean values of TSS (269.3 mg/L), PO43- (1661.6 mg/L), K+ (1220.6 mg/L) and Escherichia coli (10133.3 CFU/100 mL) exceed the recommended values set by the Cameroonian standard of treated wastewater discharge. The values of the wastewater parameters at the sampling point P3 are globally lower than those at the sampling point P1 but higher than Cameroon’s standard for PO43- and K+. These results demonstrated that the current system (filters and plants) is appropriate but not optimal. The Pareto diagram reveals that the inadequate plant controls, unfavorable working conditions, lack of maintenance andsystematic control, and outdated equipment represent 20% of the causes responsible for 80% of the WWTP's malfunction. Therefore, the implementation of corrective and preventive measures is essential for better monitoring and determinization of the optimal performance of the WWTP of the CRE camp in the "Cité-Verte".

Read More Crude oil is released into the water sources during exploration, extraction or displacement operations due to the partial dissolution, and it can remain as a layer on the surface of the water or become emulsive. Crude oil emulsion is very stable due to the presence of asphaltene and cannot be removed by the common methods. In this research, iron oxide nanoparticles were coated with oleic acid (OA), stearic acid (SA), sodium dodecyl sulfate (SDS), cetyltrimethylammonium bromide (CTAB), polyvinylpyrrolidone (PVP) and polyoxyethylene (POE), by using the same method. After synthesizing iron oxide nanoparticles and coating their surface with fatty acids and surfactants, we have tried to break the crude oil emulsion in water and remove the crude oil from the environment by adsorption via these nanoparticles. Fourier transform infrared spectroscopy (FT-IR), transmission electron microscope (TEM), scanning electron microscope (SEM), thermal gravimetric analysis (TGA), vibration sample magnetometer (VSM), energy-dispersive X-ray spectroscopy (EDS), X-ray diffraction (XRD) and Zeta potential devices were used to identify nanoparticles and their characteristics. Demulsification of crude oil in water (O/W) with nanoparticles coated with fatty acids and surfactants was studied. UV-Vis spectrophotometery was used to determine the amount of crude oil adsorption by nanoparticles. From the results, the nanoparticles coated with the fatty acids with smaller chains could more absorb the crude oil. The highest adsorption (98.03 %) was recorded for iron oxide nanoparticles coated with polyoxyethylene (Fe3O4@POE) and the lowest percentage (46.69 %) is related to the nanoparticles coated with palmitic acid in an alkaline medium. Alkalinization of the medium while coating the nanoparticles with fatty acid has increased only the efficiency in the case of oleic acid while led to a significant decrease in the efficiency for palmitic and stearic acids compared to the neutral state.

Read More Industrial activities present a significant threat to the environment and natural ecosystems like water and soil due to the release of toxic metals. This article primarily concentrates on the identification and isolation of bacteria, with the goal of effectively eliminating pollutants from industrial wastewater. In order to achieve this goal, the study was conducted to assess the ability of bacterial strains to tolerate copper (Cu) and zinc (Zn), as well as their antibiotic resistance and ability to tolerate elevated metal concentrations. The resistance of the isolates to various metals and antibiotics were assessed using the minimum inhibitory concentration (MIC) values and disc diffusion (DD) method, respectively. The technique of colony PCR was employed to determine the identity of the bacteria that were separated. Resistance to multiple antibiotics was assessed, including Penicillin, Sulfamethoxazole, Tetracycline, Erythromycin, Amoxicillin, Cefoxitin, Streptomycin, Chloramphenicol, Vancomycin, Gentamycin, Cephalothin, Rifampicin, and Novobiocin. In the current investigation, a total of 5 bacteria with a positive gram stain and 7 bacteria with a negative gram stain were identified. The study found that the effluent from the wastewater treatment plant in Razi industrial town showed resilience to copper ions, especially at a concentration of 7mM. The effluent wastewater from the refinery unit exhibited the greatest level of tolerance towards zinc, with a concentration as high as 6mM. The rise in copper and zinc levels in industrial wastewater treatment plants causes microorganisms to develop resistance to these heavy metals. The study of Gram-positive resistant bacteria conducted in this research focused on the examination of their susceptibility to zinc and copper. Notably, Staphylococcus hominis displayed resistance to a majority of the antibiotics evaluated. However, Kocuria rosea demonstrated sensitivity to all antibiotics. Agrobacterium fabrum exhibited susceptibility to all antibiotics as opposed to other Gram-negative bacteria resistant to zinc and copper. The findings of this study indicated that some strains displayed a degree of resistance to both antibiotics and heavy metals. The presence of heavy metals in bacteria isolated from a wastewater treatment plant exhibited the capability to restrict antibiotic resistance.
