The relevance of wastewater treatment service has increased in recent years, since it has a significant impact on the natural environment. A treatment plant facilitates energy generation, the recovery of products from waste, and the reuse of wastewater for industrial and irrigation purposes. An indirect environmental effect is the high energy consumption for pumping water and for tank aeration....

Advanced wastewater treatments have become an area of global focus for many communities, having in view the new, stricter discharge limits, imposed by the European Union Directives. The aim of this work is to evaluate conditions for a possible implementation of a Biological Nutrient Removal (BNR) process in the Wastewater Treatment Plant (WWTP) of Targoviste city (Romania). The problems initial...

To assess the type and load of helminths in wastewater and the quality of treatment, we examined the raw and treated wastewater of 8 wastewater treatment plants (WTP) in Tehran and 2 in Isfahan for the presence of helminth eggs during 2002-2003. Wastewater samples obtained from both inlet and effluent of each treatment plant were examined on several occasions using the modified Bailenger method...

Prediction in Wastewater Treatment Plants is an important purpose for decision-making. The complexity of the biological processes happening and, on the other hand, the uncertainty and incompleteness of the real data lead us to treat this problem modelling the data and via techniques of soft computing. Neural Networks has been the main procedure implemented. We have complemented it by genetic al...

introduction in the wastewater treatment industry, the general attentionis mostly paidto the effluent quality standards. regardless of energy consumption, the treatment plants have been designed based on experience rather than the latest scientific findings.the treatment plants are considered as a part of energy equipment which largely consumed electrical energy.thus, electricity is the great p...

Introduction Because of shortage of water resources in the world, it seems necessary to refine wastewater, particularly in arid and semi-arid areas such as Iran. Correct treatment, management and the control of refining process needs to investigate about effective parameters in this process. Therefore, because of the uncertainty and complexity in finding qualitative parameters and their relatio...

Saline municipal wastewater treatment is a challenging environmental issue in coastal cities, due to the discharge of saline water into the sewers. The present research article focuses on the phytoremediation of high saline municipal wastewater by Ruppia maritime, a widespread plant which can be found in saline medium such as traditional fish ponds, estuaries, tidal flats, salt pans, coastal pa...

In this study, modelling of Konya wastewater treatment plant was studied by using artificial neural network with different architectures in Matlab software. All data were obtained from wastewater treatment plant of Konya during daily records over four month. Treatment efficiency of the plant was determined by taking into account of input values of pH, temperature, COD, TSS and BOD with output v...

The decline in the availability and alarming pollution of the existing water resources is the major environmental problem of third-world countries. The main reason of water pollution is the disposal of untreated industrial effl uents. This study was designed to evaluate the pollution load caused by a paper mill, and to propose a wastewater treatment plant design, based on the analyses of wastew...
