Abstract

In order to tackle the worldwide problems of water pollution and shortage, this work explores the green synthesis of nanocomposite membranes for sustainable water filtering. Graphene oxide, cellulose nanocrystals, and silver nanoparticles were used as nanofillers in the fabrication of nanocomposite membranes, which were made using renewable polymer matrix (PES, PVDF, PAN). By including different polymer matrices and nanofillers, the composition analysis demonstrated the adaptability of nanocomposite membrane manufacturing, enabling the customization of membrane characteristics. Improved membrane shape and structural integrity were shown to result from the homogeneous dispersion of nanofillers inside the polymer matrix, according to characterization tests. Nanocomposite membranes demonstrated high flux rates and rejection rates for different pollutants, confirming their excellent performance in filtration experiments. The membranes’ improved fouling resistance also increased their service life and decreased the frequency of maintenance needs. Supporting the eco-friendliness of nanocomposite membrane production, an environmental impact evaluation found that it used less energy and generated less trash than traditional techniques. All things considered, nanocomposite membranes have shown great promise as long-term water treatment solutions due to their superior performance, durability, and environmental friendliness, as well as their effective production and characterisation. More study is needed to perfect membrane characteristics and solve the remaining problems that prevent their broad use in water treatment systems.

Abstract

The everyday solid waste created by human activity can be used to produce energy from which electricity can be produced. Municipal solid trash is currently increasing, which has complicated and complicated its disposal. Thus, a suitable process and planning are required for lowering solid waste. The necessity to develop an alternate source that may be used as fuel to produce electricity has arisen due to the depletion of fossil fuels as an energy source in today’s generation. We have suggested a substantial, most suitable approach that would enable us to simultaneously generate more electricity and reduce the volume of solid waste in order to fulfill the growing demand for electricity and power generation. This research also demonstrates a technique for converting biomass to energy.

Abstract

Aeration is an important parameter in water filtration system as it allows the transfer of oxygen to water through turbulence effect which subsequently increases air entrainment in the water. For water treatment application, aeration efficiency is measured to ensure continuous re-oxygenation of the unfiltered water. Aside from aeration, this paper also studies the flow patterns through the use of particle image velocimetry (PIV) setup. Through the use of real scale down physical model laboratory study is performed using PIV to obtain the velocity profile. These velocity profiles will then be used to calculate the aeration efficiency of the water in a cascade aerator system. Based on the findings, the aeration efficiency obtained from the PIV experiment has a maximum value at the lowest point of the cascade aerator system with a value of 0.0139 due to increase in mass flow rate as it moves through the steps with velocity of 0.418 m/s. Therefore, in the design of a cascade aerator system, it is advisable to increase the number of steps since it will increase the aeration efficiency of the system.

Abstract

In order to assess the fecal coliform contents in the effluent of the wastewater treatment plan of the Principal Component Analysis of these contents coupled with the physicochemical parameters of water (temperature, pH, electrical conductivity and turbidity) was carried out. The bacteriological analysis of samples taken weekly during the months of February, March and April 2009 shows that the effluent were characterized by fecal coliforms contents ranging from 3,9.104 CFU/ 100 mL and 9,104 CFU/ 100 mL with an average of 6,5.104 / 100 mL. These values were far above the recommended norm by WHO for irrigation water which is 10³/100mL. Fecal coliforms have a positive and highly significant correlation with turbidity, a poorly significant positive correlation with temperature. Also, poorly significant and negative correlations were observed pH and conductivity were observed. Among the physicochemical parameters studied only the turbidity appeared as the parameter to be monitored during the treatment of wastewater to reduce the load of fecal coliforms. A physical treatment is necessary especially decantation followed by filtration. [ABSTRACT FROM AUTHOR]

Abstract

At 15 degree C, different concentrations of Phaeodactylum tricornutum are given to Crassostrea gigas . Ingestion, filtration, respiration, ammonia excretion have been measured. All ecophysiological response, except dissolved excretion, are dependent of food concentration. Energy balances have been determined and selectivity of particle size observed., Des huîtres adultes Crassostrea gigas ont été soumises à un régime alimentaire monospécifique (Phaeodactylurn tricornutum) à différentes concentrations et à la température de 15°C. Les taux d'ingestion, de filtration, de biodéposition ainsi que de respiration et d'excrétion ammoniacale ont été mesurés pour chaque condition expérimentale. Toutes les réponses écophysiologiques sont fonction de la concentration en nourriture du milieu à l'exception du taux d'excrétion dissoute. Les conditions optimales de niveau trophique semblent se situer à la concentration de 10.106 cellules par litre soit 0.7 mg de matière sèche d'algues ou 161 ug de carbone organique. Des bilans énergétiques ont pu être déterminés et un phénomène de sélectivité de la taille particulaire a également été mis en évidence.
