Biological denitrification of high strength nitrate waste using preadapted denitrifying sludge.
Denitrification of synthetic high nitrate waste containing 9032 ppm NO(3)-N (40,000 ppm NO(3)) in a time period of only 6h has been achieved in our previous study using activated sludge. The activated sludge culture was acclimatized by a stepwise increase in the nitrate concentration of synthetic waste. In the present work, studies were carried out on the changing microbial population of the sl...
متن کاملBIoLoGICAL MonIToRInG oF WATERS
The management of natural environments passes from the possibility to know environmental features and their evolution in time. Generally quality assessment is based on chemistry or microbiology, and physical values, to justify laws and sanctions. The big problem of these precise measures, however, is in the necessity they have to be recorded in a more or less continuous monitoring. Punctual mea...
متن کاملComparison of ethanol, methanol and succinate effects as carbon sources on effluent biological denitrification
Abstract Background: Increase of nitrate concentration in water sources is becoming a serious problem in many parts of the world. Nitrogen containing compounds released into environment can create serious problems, such as eutrophication of water sources and hazard potential to human health, because it has potency of causing methemoglubinemia disease and cancer. Between recommended methods, bi...
متن کاملMimic Behavior in Home Waste-waters Management
We present results of a household-level survey on behaviors regarding refuses in the home waste-waters network. Interpreting survey results in a panel-data logit results show that most socio-economic and public good-related respondent’s characteristics do not play a significant role in explaining choices to discard in the home waste-waters network. The only significant regressor, apart from the...
متن کاملThe effect of metronidazole on biological denitrification of Pesudomonas stutzeri in wastewater
Background : Pseudomonus stutzeri bactrerium is one of the most important and effective denitrifier bacteria in wastewater. With regard to the importance of effects of nitrate on water resources and human health and role of metronidazole inhibition, this study was done with the aim of survey of effect of metronidazole different concentrations on biological denitrification of Pesudomonas stutzer...
