Background & objective: Microbial contamination is one of the main concerns about the use of treated wastewater in irrigation. Therefore, the present study conducted to investigate the effect of treated wastewater on microbial contamination of urban landscape soils in Zahedan. Material & methods: In this study, a 1600 m2 plot of palm trees in Zahedan were irrigated with treated wastewater and o...
the methods which are used to analyze microstrip antennas, are divited into three categories: empirical methods, semi-empirical methods and full-wave analysis. empirical and semi-empirical methods are generally based on some fundamental simplifying assumptions about quality of surface current distribution and substrate thickness. thses simplificatioms cause low accuracy in field evaluation. ful...
the purpose of the present study was to investigate the latent pattern underlying reading ability . some 272 male and female participants. english majors at the ba level , participated in the study. two valid tests were used in this study, the reading test developed exclusively for the purpose of this project and academic reading section of ielts. to investigate the possible latent underlying...
maragheh-bonab active cultivated plain is located in south east of east azarbaijan and consists of valuable groundwater resources. maragheh industrial park is nearly located in the recharge area of this plain. kaveh soda and paper mill factories that are located in this park produce high volume of wastewater is continually recharged in the plain. in this article, the effect of industrial wastew...
background: groundwater resources in arid and semi arid regions are very important. groundwater is contaminated by agricultural, industrial and municipal activity which as a result reduces its quality. investigating of the chemical quality of the groundwater is emphasized to identify pollutant environmental impacts associated with incorrect waste disposal practice. this research investigated th...
Limited water resources in arid and semi-arid regions are one of the major limiting factors in agricultural production. Thus, unconventional water resources, such as urban and industrial treated wastewater, may be used for irrigation. Application of wastewater to soil may cause accumulation of heavy metals (HMs). Soil pollution causes uptake of these metals by plants and their entrance to food ...
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...
the growing scarcity of fresh water is driving the implementation of wastewater treatment and water reuse on an increasingly large scale. various methods have been developed and used for water reuse from wastewater; however, the membrane distillation (md) process, as a promising separation technology, has recently gained more attention. the md process is a non-isothermal membrane-based separati...
