Abstract

Biosorption of heavy metals can be an effective process for the removal of copper ions from wastewater. Use of Saccharomyces cerevisiae has been explored in the laboratory scale experiment as a low cost adsorbent for the reduction of copper in batch techniques. The influence of metal concentration, influence of temperature, pH were also studied. From experimental results it is observed that almost 72 - 88.5% copper can be removed from the solution using Saccharomyces cerevisiae. This process is environment friendly and reduces the huge amount of indiscriminate effluent discharges around the small industry concerns. It may provide an affordable technology for small and medium-scale industry.

Keywords

Abstract

Soil properties of different location of Ganga and Matla are different depending on the flow of river along with its entire path. Soil and water property of both of these courses have been deteriorating due to release of agricultural run off, domestic sewage, indus­ trial effluents. The soil receives serious polluting substances through anthropogenic ac­tivities which include organic wastes, toxic chemicals, heavy metals from industrial efflu­ents etc.

This paper studies different soil properties of rivers Ganga and Matla of West Bengal to verify if the soils can be used as liner materials for the hazardous waste landfill.

Abstract

To protect ground w ater from landfill contam inants, soil liners are constructed as a simple liner which provide the finalline of defuse against groundwater contamina­tion in landfill. Clay minerals are the most important chemical weathering product of soil. The very low permeability of the clay barrier is expected to lengthen the lifetime of the landfill and slow down the consequent release of contaminants. It is observed from the experimental results that using soil as liner medium, the groundw ater con­tam ination of heavy metals like lead, cadmium, cobalt, copper can be reduced to 28 - 97% depending on the metal characteristics. A mathematical expression is developed depending on the experimental conditions and it is observed that the experimental result shows satisfactory agreement with the experimental results.

Keywords
