Many sewage waste treatment systems are aiming for complete pathogen removal which necessitates search for novel approaches that does not harm the environment. One such novel approach is exploring the possibilities of bacteriophages for pathogen removal. Hospital wastewater was collected from different locations of Tamil Nadu and used for the study. The total heterotroph and total coliform popu...

for social and cultural condition of country using weakest and returned water in different uses especially in agricultural consumption is not public and also is faced social opposition. in this study, it is tried to investigate several products in different levels of consumption according to consumer’s views who reside in tehran by mean of willingness to use concept. data are collected in 2012 ...

The microbial capacity to degrade simple organic compounds with quaternary carbon atoms was demonstrated by enrichment and isolation of five denitrifying strains on dimethylmalonate as the sole electron donor and carbon source. Quantitative growth experiments showed a complete mineralization of dimethylmalonate. According to phylogenetic analysis of the complete 16S rRNA genes, two strains isol...

Wastewater sludges are used in agriculture as soil amendment and fertilizer, with regard to their organic matter and nutrient content. However, availability of nitrogen and phosphorus from sludge-amended soils and their transfer in runoff may lead to eutrophication of downstream surface water. The aim of this study is to establish and compare the effect of two different sludges on these transfe...

As an important facility for effectively controlling water pollution discharge and recycling waste resources, accurate sewage treatment plant extraction is very protecting quality, function, sustainable development of the environment. However, due to presence rectangular circular facilities in plants, shapes are diverse scales different, resulting poor performance conventional object detection ...

the study was conducted during 2002- 2007 in the first and last stage of a four-year rotation (sugar beet, forage maize, onion, wheat and sugar beet) at research station of irrigation and drainage rudasht. in each year, four treatments of organic fertilizers (25 and 50 t/ha urban compost and 15 and 30 t/ha sewage sludge) with a control (no organic fertilizer) were studied in a randomized comple...

PURPOSE The association between exposure to bacteria and endotoxins in sewage dust and the serum concentrations of pneumoproteins in sewage treatment plant workers were studied. METHODS Forty-four workers from eight sewage treatment plants and 38 reference workers participated in the study. Microbial aerosol was collected by personal inhalable samplers. The concentrations of bacteria and endo...

in order to study the effects of irrigation levels on growth criteria, yield components and seed yield of four ecotypes of sesame (sesamum indicum l.), a field experiment was conducted as factorial based on a randomized complete block design with three replications at the agricultural research station, ferdowsi university of mashhad, during growing season 2010-2011. three irrigation levels (200...

seed germination is a crucial stage in the plant life cycle and salt tolerance during germination stage is vital for the establishment of plants in saline soils. in order to evaluation of sesame (sesamum indicum) landraces germination to salinity stress at different temperature, an experiment was conducted at ferdowsi university of mashhad, collage of agriculture during 2009. experimental type ...
