Experimental Investigation on Heavy Metal Adsorption From Sanitary Landfill Leachate Using Clay Layer Containing Zeolite
, M.Sc. Thesis Sharif University of Technology ; Pak, Ali (Supervisor) ; Vosoughi, Manoochehr (Co-Advisor)
Abstract
Leachate migration from solid waste landfills into the subsurface environment is one of the significant problems of landfills. This can cause lots of problems for local soil and water to sources according to the contaminants appear in the leachate. Usually, landfill sites include at least one compact clay liner to prevent contamination of groundwater by produced leachate. Over the last decades investigators have been attracted to the structure and removal capacity of this liner. In this study, the effect of the addition of Zeolite to Kaolinite soil for the removal of heavy metal (manganese and zinc) from landfill leachate and the effect of decreasing the thickness of the soil layer has been...
The Feasibility Study of Micronized Powder Plant for Exporting (UNIDO METOD)
, M.Sc. Thesis Sharif University of Technology ; Hooshmand, Mahmoud (Supervisor)
Abstract
This thesis deals with the development of a hypothetical micronized powder factory and trying to test and engage in this hypothetical development of the following plant, it considers following factors:
1-Domestic & International market
2-Plant location
3-Plant design & development
a.machinery
b.technology & equipment
c.human resource
d.environment
e.packing
4-raw material
5-shipping & transport
To evaluate above factors the UNIDO methodology is used in this research work. The UNIDO methods are using a process by which feasibility studies of production facilities or plant are base on. After reviewing a variety of factors, ranging from financial...

The Effect of Gas-oil Contamination on Geomechanical Properties of Sandy Clay Soils
, M.Sc. Thesis Sharif University of Technology ; Sedghiani, Mohammad Hossein (Supervisor)
Abstract
During recent years, decay, fraction, corrosion and leakage of oil pipe lines have resulted in soil pollution. Gas oil is one of the main causes of soil pollution in different places. Soil and pollutant interaction results in varying soil geotechnical properties which causes shear strength, permeability, etc. to change drastically. After careful recognition of the problem, it should be encountered in a good manner. Therefore, comprehensive investigation regarding the effect of oil production on soil should be done. In this thesis, properties of combination of sand, kaolinite and pollutant in different situation such as different fine grain content, different relative compaction, and...
