sweet sorghum that is adapted to the country hot and dry climatic condition, was selected as a raw material for biofuel and biogas production. bioethanol is produced from sweet sorghum stalks and grains and biogas is produced from its byproducts. the purpose of this study was to plant sweet sorghum irrigated with different qualities of water in order to produce biofuels. this experiment was con...

this study was conducted to investigate the characteristics of input and output wastewater of the bandargaz wastewater treatment plant on the basis of the data collected during operation and the samples taken during the study period. for this purpose, three samples were taken from the outflow wastewater and 25 quality parameters were tested. also, four soil samples were taken from the soils whi...

in order to investigate the effect of domestic wastewater and normal water (well water) on soil chemical properties and alfalfa yield, a research project was conducted for three years in chahartakhteh research station. the experiment was performed in randomized complete blocks design including four treatments in three replications. treatments were as follows: t1: irrigation with normal water at...

Population’s exponential growth along with drought has increased water resources limitation, especially in arid and semi-arid area. Therefore, the use of non-conventional water is an important tool for water resource management. If unconventional water has no negative impact on soil properties and water, it can be used for irrigation coupled with desertification projects. So, this paper tries t...

background : collection and storage of roof rain water have been practiced for long time ago in iran and many other countries. water of cisterns is usually used as potable water. in golestan province many of rural torkman residents reservoir the most part of their potable water from roof rain in cisterns. in this province there are over 2600 cisterns. methods : to study the water quality, micro...

PURPOSE Denitrification is an important biochemical process in global nitrogen cycle, with a potent greenhouse gas product N(2)O. Wastewater irrigation can result in the changes of soil properties and microbial communities of agricultural soils. The purpose of this study was to examine how the soil denitrification genes responded to different irrigation regimes. MATERIALS AND METHODS Soil sam...

Over the past 20 years, the new industrial cities were considered as the main solution to most of the problems facing the metropolitan industrial areas and to assist in the national industrial development. In these new communities, industrial and domestic activities result in the production of vast quantities of wastewater; the improper disposal of which may cause serious environmental hazards....

OBJECTIVE The goal of the current study was to gain insight into the prevalence and concentrations of antimicrobial resistant (AMR) Escherichia coli in Dutch surface water, and to explore the role of wastewater as AMR contamination source. METHODS The prevalence of AMR E. coli was determined in 113 surface water samples obtained from 30 different water bodies, and in 33 wastewater samples obt...
