Bioaugmentation as a tool to accelerate the start-up of anoxic-oxic process in a full-scale municipal wastewater treatment plant at low temperature
Start up of anoxic-oxic process in a full-scale municipal wastewater treatment plant at low temperature was studied in this paper. Bioaugmentation technology was used to accelerate the start up. Aeration rate and feed style of influent were also controlled as associated measure to reduce the negative effect of low temperature on start up. The results showed that the process was successfully ...

Opportunities for microbial electrochemistry in municipal wastewater treatment – an overview
Microbial bioelectrochemical systems (BESs) utilize living microorganisms to drive oxidation and reduction reactions at solid electrodes. BESs could potentially be used at municipal wastewater treatment plants (WWTPs) to recover the energy content of organic matter, to produce chemicals useful at the site, or to monitor and control biological treatment processes. In this paper, we review ...

Thermodynamic analysis and assessment of a municipal wastewater treatment system: a field study on sewage treatment
This paper is a field study on thermodynamic analysis and assessment of an actual municipal wastewater treatment facility. The system operation is described and a methodological approach based on the energy and exergy analyses is provided to assess the performance of a complex wastewater treatment system. Since the specific exergy value of the sludge is increased through treatment process, a new ...

CH#831 - Municipal Wastewater Treatment Plant
Introduction The Wastewater Treatment Plant is a rotating biological contactor treatment process preceded by bar screening, grit removal and primary settling. Subsequent to the secondary treatment process, the flow stream enters a chlorine contact tank and then goes to the receiving stream. The program study was started on March 4th. The objectives were a recovery from filamentous infestation, ...

Reconsidering rotating biological contactors as an option for municipal wastewater treatment
There are many domestic wastewater treatment processes in use today. Generally, they are all biological systems and they may be broadly categorized as either fixed film processes or suspended growth processes. During the 1970s and early 1980s, the rotating biological contactor process (RBC), a particularly efficient fixed film process, became popular. However, the primary manufacturer of RBCs in ...

Abatement efficiency of municipal wastewater treatment plants using different technologies (Orbetello Lagoon, Italy)
Two small-scale municipal wastewater treatment plants (Neghelli and Terrarossa) discharging effluents into a lagoon of great environmental interest and highly stressed by tourism (Orbetello, Italy) were monitored over the year 2001. We evaluated plants' performances developing a general efficiency indicator of removal to select the suitable purification technology (activated sludge, Neghelli vs. ...
