Aims of the Study: This study was carried out to determine the effective factors in environmental health status of grocery stores in the city of Qom (located in the center of Iran). Materials & Methods: In this cross-sectional study, 283 grocery stores from 3 different regions were selected randomly using stratified sampling. Data were gathered through ...

[ 3 ] - Adsorption of Lead from Aqueous Solution by Modified Beech Sawdust

Sawdust is now being investigated as an adsorbent to remove contaminants from aqueous solution. Heavy metals can be decreased very effectively with the organic material. In this research, adsorption of Pb (II) onto modified beech sawdust in a batch system was investigated. Sawdust was collected from timber mill of Qom, Iran, and modified with H2SO4 and NaOH. Then, the effe...

[ 4 ] - Producing Renewable Energy from Municipal Wastewater Treatment Using a Bio–electrochemical System

Concurrent renewable energy production and wastewater treatment are two main reasons for using microbial fuel cells (MFCs). In this study, real wastewater was used for treating and power generation by air cathode microbial desalination cells (ACMFC). The total duration of voltage generation by ACMFC was about 151.9 ±23.2 h. The maximum voltage produced from municipal wastewater treatment was 27...
