Global water scarcity is driving the need for identifying new water source. Wastewater could be a potential water resource if appropriate treatment technologies could be developed. One of the barriers to obtaining high quality water from wastewater arises from the presence of organic micropollutants, which are biologically active at trace levels. Removal of these compounds from wastewater by cu...

The regularities of the change concentration microorganisms and water-soluble organic compounds in polluted water conditions cavitation treatment influence amount biological pollution on value chemical oxygen consumption are investigated.

to compare the seed characteristics in accessions of atriplex canescens under exclosure and non-exclosure conditions, two even-aged sites were selected with an area of 400 ha as the exclosure and 1000 ha as non-exclosure area. to conduct the study, 30 species were randomly selected in autumn 2009 in reference area of the sites and seeds were collected. some important seed characteristics were s...

background; turbidity removal using inorganic coagulants such as iron and aluminum salts in water treatment processes causes environmental and human health concern. historically, the use of natural coagulant to purify turbid water has been practiced for a long time. recent research indicates that descurainia sophia seed can be effectively used as a natural coagulant to remove water turbidity. m...

The microbial community of a full-scale, biologically active drinking water filter was surveyed using molecular techniques. Nitrosomonas, Nitrospira, Sphingomonadales, and Rhizobiales dominated the clone libraries. The results elucidate the microbial ecology of biological filters and demonstrate that biological treatment of drinking water should be considered a viable alternative to physicochem...
