groundwater contamination is a serious problem facing the countries. because groundwater is vulnerable to contamination from a variety of sources, and, once contaminated, it is very difficult to restore to its original quality. the main objective of this study was evaluation of groundwater quality in shahrekord aquifer and finding the source of the groundwater contamination. some of the chemica...

In the present paper, the idea of braking energy regeneration and reusing that energy during acceleration for a refuse truck is comprehended. According to their driving cycle, the refuse trucks have a good potential for braking energy regeneration. On the other hand, hydraulic hybrid is a powertrain with high power density which is appropriate for energy regeneration. In the primary stage of th...

today, water resources stored in reservoirs is one of the basic sources of drinking-water. the elements in the sediments of reservoirs are the most important factors affecting water quality. unlike the primary plan, due to water shortage problems, nowadays, almost all the stored water in the kardeh reservoir is allocated to drinking water. from the other side in the catchment area of this dam a...

An alyses of the components of municipal refuse were assembled, from which an average· composite analysis was calculated. The analyses of the flue and stack gases from 18 municipal incin erators were also tabu­ lated and plotted. A marked difference was n oted be­ tween the analyses of the stack gases and those to be expected from the combustion of the composite refuse. Much of the difference c...

Process engineering is applied to the design of a new I concept of a municipal incinerator. Each of seven incin· eration process areas are analyzed separately and the equivalent process in the chemical and metallurgical industries examined for proven design features applicable to incineration. Examples of integration of designs for process areas are given. Advantages of this new inciner­ ator c...
