introduction: the development of an appropriate model for the quality control of an industrial wastewater treatment system can save the time as well as the cost. this study was performed to determine an appropriate model in order to predict the cod and tkn parameters by bod5 and nh4+ in the meybod industrial estate waste water treatment plant (wwtp). methods: this descriptive – analytical study...

flocculation processes during estuarine mixing can reduce the elemental concentrations of river water. in the present investigation, natural flocculation processes concept is used to reduce the elemental contents of industrial wastewater. for this purpose, various amounts of saline water were added to an artificial industrial wastewater with known concentrations of heavy metals. the results of ...

We have investigated the interactions between economic growth and industrial wastewater discharge from 1978 to 2007 in China's Hunan Province using co-integration theory and an error-correction model. Two main economic growth indicators and four representative industrial wastewater pollutants were selected to demonstrate the interaction mechanism. We found a long-term equilibrium relationship b...

The performance of a novel industrial membrane bioreactor (MBR) comprising denitrification, nitrification and ultrafiltration for the secondary treatment of primary treated animal rendering wastewater has been compared with an experimental, low-cost and novel vertical-flow constructed treatment wetland planted with Typha latifolia L. The process wastewater followed pre-treatment by dissolved ai...

In the context of urban drainage, the protection of surface waters from the effects of wastewater discharges has assumed increasing importance. As a result of human activity, there is sometimes contamination of water resources due not only to the phenomenon of diffuse pollution, but also as a result of specific effluent discharges (such as those from different industries or farming and by some ...

introduction: treatment of wastewater due to product and consumption of material cleaning with special physicochemical characteristics is difficult, and therefore can cause significant environmental problems such as eutrification, toxicity, algae bloom and etc.to stop these consequences, assessing the quality characteristics of this wastewaters is necessary. to investigate about the appropriate...

Industrial WWTP’s have to provide a 100 % reliability and availability for the discharging facilities (Bury et al., 2002). The industrial WWTP in this study treats wastewater the same way as most municipal WWTP, i.e. with an activated sludge process. However, some differences can be pointed out. The first problematic difference is that the composition of industrial wastewater fluctuates conside...

background: considering the toxic effects of heavy metals and microbial pathogens in industrial wastewaters, it is necessary to treat metal and microbial contaminated wastewater prior to disposal in the environment. the purpose of this study is to assess the removal of heavy metals pollution and microbial contamination from a mixture of municipal and industrial wastewater using membrane bioreac...
