    Abstract: This paper presents the results of experimental work of dewatering by pressure filter using geotextile, aluminium sulphate and nanoparticles. In the present day, industries produce a lot of sludge for which open dumping is done, this causes several water borne diseases, bad odour, attraction of flies and land degradation. Sludge is the main cause f... Show More

    Abstract: The normalized integrated concentration of pollutant has been obtained after solving temporaly diffusion equation using the method of separation variable considering the eddy diffusivities which measuring at night or at any time in high inversion layer in the stable condition. The dataset is observed from the “Project prairie Grass” (Barad 1958) wh... Show More
