background and purpose: disposing sludge from industrial wastewater treatment plants (iwwtps) is a serious issue because it can affect human and animals health, and also environmental quality. in this study, sludge from an iwwtp was analyzed regarding its physicochemical characteristics and disposal options. materials and methods: grab sampling was used to collect 12 sludge samples biweekly (ma...

This study examined the biodegradation of RDX in wastewater from an industrial wastewater treatment plant at the Holston Army Ammunition Plant in Kingsport, TN. Serum bottles containing 100 ml of a basal salts medium amended with 10 percent (v/v) sludge from the anoxic filter at the plant were amended with RDX and incubated under methanogenic conditions. Biodegradation intermediates correspondi...

This paper considers control structure selection for a biological wastewater treatment process, with emphasis on identifying controlled variables that contribute to minimize economic costs. This is achieved according to the selfoptimizing procedure proposed by Skogestad (2000). The aim is to demonstrate how, with simple considerations on the control structure design, the efficiency of a wastewa...

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. ...

Broad-host-range plasmids are frequently associated with antibiotic resistance genes and can quickly spread antibiotic resistant phenotypes among diverse bacterial populations. Wastewater treatment plants have been identified as reservoirs for broad-host-range plasmids carrying resistance genes. The threat of broad-host-range plasmids released into the environment from wastewater treatment plan...

background: this study aimed to survey a total five common human and veterinary antibiotics, including ampicillin, oxytetracycline, enrofloxacin, tylosin, and ciprofloxacin based on spe-lc-ms-ms technology in a wastewater treatment plant at central plateau of iran. also two sampling techniques, passive and grab samplings were compared in the detection of selected antibiotics. methods: in februa...

Cascade process, such as wastewater treatment plant, includes many nonlinear sub-systems and many variables. When the number of sub-systems is big, the input-output relation in the first block and the last block cannot represent the whole process. In this paper we use two techniques to overcome the above problem. Firstly we propose a new neural model: hierarchical neural networks to identify th...

The lack of proper wastewater treatment results in production of CO(2) and CH(4) without the opportunity for carbon sequestration and energy recovery, with deleterious effects for global warming. Without extending wastewater treatment to all urban areas worldwide, CO(2) and CH(4) emissions associated with wastewater discharges could reach the equivalent of 1.91 x 10(5) t(CO2)d(-1) in 2025, with...
