BACKGROUND The aim of the study was to design and implementation of integrated solid wastes management pattern in Shahroud industrial zone, evaluates the results and determine possible performance problems. This cross - sectional study was carried out for 4 years in Shahroud industrial zone and the implementation process included:1- Qualitative and quantitative analysis of all solid waste gener...
Residues are produced in all stages of human activities in terms of composition and volume which vary according to consumption practices and to production methods. Forms of significant harm to the environment are associated to volume of generated material as well as to improper disposal of solid wastes, whose negative effects are noticed more frequently in the long term. The solution to this pr...
Hexavalent chromium, a highly toxic metal ion employed in industrial activities, is considered as a first priority pollutant. In this study, the capsule walls of the boll of cotton (cotton waste, CW) and the waste obtained from pruning barberry bushes (barberry waste, BW) were investigated as cheap and locally available adsorbents for Cr (VI) removal. The adsorption behavior, equilibrium, and k...
gol-e-gohar iron ore mine of sirjan in southern part of iran is a large open pit that operates below the groundwater table and during mining operation, dewatering is required to prevent operation processes from flooding. current operation is going on by digging wells in or out of the pit and pumping to prevent flooding. as a result of the former dewatering operation a vast deep cone of depressi...
recycling and reuse of wastewaters are of the new policies that provide water resources to respond to the need of the growing population. in many societies, social acceptability of these processes has an important role in the success of the reuse from refined wastewater, because the final product of this process is in direct relation with the consumer. therefore, social and cultural implication...
1,3-Dichloropropene is a mixture of volatile cis and trans isomers and is primarily used as a nematocide to fumigate soil before planting. Commercial formulations of 1,3-dichloropropene contain stabilizers to inhibit degradation of the compound (Table 3-1). Older formulations contained chroropicrin or epichlorohydrin, whereas currently, the less toxic epoxidized soybean oil is used as a stabili...
The authors wish to thank the following faculty of the College of Agriculture and Life Sciences and Virginia Cooperative Extension (VCE) for their time and valuable contributions in reviewing the manuscript for this publication: Dr. Eldridge Collins, Agricultural Waste Specialist, Department of Biological Systems Engineering; Dr. Darrell Bosch, Assoc. Professor, Department of Agricultural and A...
The aim of this project was to remove chloride ions from Eshidiya industrial waste water to be reused in the flotation cells. The industrial wastewater was treated by passing it through ion exchange column. During the experiments, two types of resins were used: anion resin and mixed resin (cation / anion).The selectivity coefficient and the separation factor were calculated in those experiments...
