This paper examines potential uses of naturally growing aquatic plants for wastewater purification. These plants enhance the removal of pollutants by consuming part of them in the form of plant nutrients. This applies to urban and agricultural wastewater, in particular, where treatment units of different sizes can be applied at the pollution source. The effectiveness of wastewater purification ...

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. ...

Wastewater management focused, for many years, on the treatment of wastewater to protect the environment and safeguard the public health. An integrated approach to wastewater management is more extensive and includes the control of generation, collection and transport, treatment, disposal and reuse of wastewater in a manner that is in accord with the best principles of public health, economics,...

conclusions to solve the above mentioned difficulties, fundamental study most be carried out to discover the novel methods of ferrate(vi) production, focusing on increasing the product stability and the production yield. results despite the existence of these technologies, there is no full-scale application of ferrate(vi) in the water and wastewater industry which it is due to difficulties asso...

There is an astonishing lack of awareness among many technical service providers and environment practitioners with regard to the range of wastewater treatment methods and equipment available. The paper presents an effective training and reference tools focusing on wastewater treatment and water reuse systems. The tool is composed of four parts: reference system, case base manager, treatment ad...

An overview is presented on the projects that are being carried out by Water Quality and Treatment Laboratory team of LNEC which use activated carbon based technologies for treating water or wastewater. Emphasis is given to the chemical enhancement of conventional wastewater treatment using “green” powdered activated carbon options, hybrid adsorption/ membrane processes or biologically active c...

This paper dealt with a detection of electric Arc signal by using Matched Filter in wastewater treatment plant of SWG(Smart Water Grid). We proposed one of solutions to prevent fires due to arc signals happened frequently in SWG linked wastewater treatment plant. As an arc signal detection solution in wastewater treatment plant of SWG, we proposed MF(matched filter) based arc signal detection a...

The application of membrane technology in water and wastewater treatment is increasing due to stringent water quality standards. Nanofiltration (NF) is one of the widely used membrane processes for water and wastewater treatment in addition to other applications such as desalination. NF has replaced reverse osmosis (RO) membranes in many applications due to lower energy consumption and higher f...

this study aims to inspect the performance of the wastewater treatment system of the pars oil refinery. quantity and quality of wastewater are determined through samplings and measurements. the performance of system is evaluated considering total suspended solids, total dissolved solids, phosphate, chemical oxygen demand, biochemical oxygen demand, ammonia nitrogen, furfural, oil and ph. for pr...
