Quality assessment of treated wastewater to be reused in agriculture
In this study, the quality of a treated wastewater for agricultural and irrigation purposes was investigated. 39 quality parameters were investigated at the entrance of an effluent channel to the destination plain in monthly time intervals during a year. The aim of this study was drawing an analogy between analyses results and the latest standards in the world (nationwide and internationally), the agricultural and irrigation usage indexes and the Wilcox diagram. The results showed that some parameters such as turbidity, total suspended solids, electrical conductivity, sodium, detergents, total coliform and focal coliform, ammonium, residual sodium carbonate, the Kelly’s Ratio and the Wilcox diagram were exceeding the permissible limit and are not suitable for agriculture and irrigation. It was found that the aquifers in the study area were polluted by natural salinity and geogenic source. As a result, application of the treated wastewater from Qom for agriculture and irrigation purposes needs to be revised and monitored. An action plan is also needed to manage a huge source of water and to avoid further environmental and health risks.
A pilot field study was conducted at the Jagjeetpur Municipal Sewage treatment plant situated in the Haridwar town in Uttarakhand state, India. The objectives of the present study were to study the effect of treated wastewater on the production of various paddy varieties (Sharbati, PR-114, PB-1, Menaka, PB1121 and PB 1509) and the emission of GHG gases (CO2, CH4 and N2O) as compared to the same...متن کامل
ions for component compositions can be domain-specific and areeither technical or consumer-related. The group of products (or systems) thatcan be built from technical abstractions forms a product family  (or sys-tem family). The group of products that can be built from consumer-relatedabstractions forms a product line. These consumer-related abstractions have anon-techn...متن کامل

Scientific discovery and innovation are advancing along fundamentally new pathways opened by development of increasingly sophisticated software. Software is also directly responsible for increase...متن کامل
Guidelines for the microbiological quality of treated wastewater used in agriculture: recommendations for revising WHO guidelines.
Three different approaches for establishing guidelines for the microbiological quality of treated wastewater that is reused for agriculture are reviewed. These approaches have different objectives as their outcomes: the absence of faecal indicator organisms in the wastewater, the absence of a measurable excess of cases of enteric disease in the exposed population and a model-generated estimated...متن کامل
Water is the most important resource of a country, and of the entire society as a whole, since no life is possible without water. It has this unique position among other natural resources, like minerals, fuels, forests, livestock etc. because a country can survive in the absence of any other resources, except this one. El-Serw Fish Farm situated on the southern west shore of Lake Manzalah near ...متن کامل

امروزه مسئله ی اساسی در رویکرد های جدید زبانشناسی، ابعاد اجتماعی و ایدئولوژیک زبان تلقی می شود. گروه های مختلف اجتماعی، سیاسی و یا مذهبی از زبان به عنوان ابزاری برای دستیابی به اهداف درون گروهی خود استفاده می کنند (ون دایک، 2003). آنها معولا ایدئولوژی خود را صریحا ابراز نمی کنند بلکه آن را در غالب کلمات و ساختارهای زبانی پنهان نگه می دارند. تشخیص ایدئولوژی های پنهان در گفتمان نیازمند این موضوع ...
