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 wastewater treatment plant (WWTP).  Materials and Methods: This descriptiv...

Background & Aims of the Study: The use of urban wastewater in agriculture is receiving renewed attention with the increasing scarcity of freshwater resources in many arid and semiarid areas, despite its associated health and environmental risks. Long term wastewater usage for irrigation results in accumulation of heavy metal in soils and plants. So, due to the environmental and health risks as...

In this paper we present an environmental decisionsupport system (named DAI-DEPUR+) and a reactive linear planner (named WaRP), and their application to the wastewater domain. The environmental decision-support system: receives and processes onand off-line information about a wastewater treatment process. uses this information for selecting and revising models of the treatment-system dynamics. ...

this research, in addition to survey the existing data on the quality of sahebgharanieh wastewater treatment plant's effluent in the previous years, by runing a three months monitoring stage, studies the conditions of the final settling and aeration basin and the variations of the influent and effluent quantity and quality in removing of major pollutants (bod, cod, tss), while scrutinizing the ...

the occurrence and fate of trace-level contamination of pharmaceuticals in the aquatic environment has been recognized as one of the emerging issues in environmental chemistry. the effluents of wastewater treatment plants, usually directly emitted to the environment, often contain the anti-inflammatory drug diclofenac. diclofenac was chosen because it is of high consumption; by background liter...

This paper presents the development and implementation of a Real-Time Expert System (RTES) for the supervision and control of a wastewater treatment pilot plant (WWTPP) with biological removal of organic matter and nutrients. The hardware architecture contains different supervision levels, including two autonomous process computers (plant control and analysers control) and a PLC, being the ES t...

The influence of WWTP treatment standard on contaminant breakthrough is explored for 293 compounds.

METHs are drugs that enter wastewater through the feces and urine of users. Conventional treatment plants not capable removing this type emerging contaminant, but, in recent years, techniques have been developed to abate abuse. The present investigation focused on obtaining technique keeps best balance between comparison criteria considered: efficiency; costs; development stage; waste generatio...
