The paper provides a critical comparison between mesophilic and thermophilic anaerobic treatment of PTA wastewater through diagnosis of a case study. Aspects covered are bioavailability, biodegradability, microbial population, thermodynamics, kinetics involved and bioreactor design for PTA wastewater treatment. The results of the case study suggests that onestage thermophilic anaerobic reactor ...

Clean fresh water is essential to our life. Unfortunately, in our consumer-based economy, a large amounts of wastewater having been generated by industrial plants. Wastewaters produced in many industrial plants often contain organic compounds which are toxic and not amenable to direct biological treatment. These wastewaters must be treated in order to meet the specifications for discharge or fo...

Advanced oxidation processes (AOPs) are widely used for the removal of recalcitrant organic constituents from industrial and municipal wastewater. The aim of this study was to review the use of titanium dioxide/UV light process, hydrogen peroxide/UV light process and Fenton’s reactions in wastewater treatment. The main reactions and the operating parameters (initial concentration of the target ...

The paper present the possibility of automatic control of the biological wastewater treatment station with applications in Romanian Chemical Companies. In this paper are developed a mathematical model for biological aeration basins and two automatic control systems (conventional control structure using threepositional controllers or PLC and advanced control structure using state estimators) for...

There are several contaminants in wastewater, with organic pollutants playing the major role. Many kinds of organic compounds, such as PCBs, pesticides, herbicides, phenols, polycylic aromatic hydrocarbons (PAHs), aliphatic and hetercyclic compounds are included in the wastewater, and industrial and agricultural production as well as the people living could be the source of organic wastewater e...

Treatment process models are efficient tools to assure proper operation and better control of wastewater treatment systems. The current research was an effort to evaluate performance of a submerged membrane bioreactor (SMBR) treating combined municipal and industrial wastewater and to simulate effluent quality parameters of the SMBR using a radial basis function artificial neural network (RBFAN...

maragheh-bonab active cultivated plain is located in south east of east azarbaijan and consists of valuable groundwater resources. maragheh industrial park is nearly located in the recharge area of this plain. kaveh soda and paper mill factories that are located in this park produce high volume of wastewater is continually recharged in the plain. in this article, the effect of industrial wastew...

Collection and reuse of wastewater and sewage in agriculture, natural resources and green environment is one way to conserve water resources and environmental. The aim of this study were to investigate the effects of wastewater Sirjan golgohar industrial on the characteristics of cultivated soils in several species of pasture trees. This study was performed at the Sirjan city which is located i...

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...

Industrial wastewater contains a lot of pollutants and therefore needs special treatment processes. The treatment process may contain mechanical, biological, chemical, physical and physiochemical such as Coagulation – Flocculation process. The goal of this experimental work was to investigate the effects of coagulationflocculation and dissolved air flotation as a hybrid process of industrial wa...
