Energy breakdown of wastewater treatment plant with activated-sludge treatment (Based on Tchobanoglous, et al., 2004)

Context 1

... advanced wastewater purification processes require more energy, for instance ultraviolet disinfection processes and activated sludge treatment. Figure 2 illustrates the energy breakdown of typical wastewater treatment plant having activated-sludge process. (Tchobanoglous, et al., 2004) As we can see from Figure 2, more than a half of energy is consumed by an aeration process. ...

... 2 illustrates the energy breakdown of typical wastewater treatment plant having activated-sludge process. (Tchobanoglous, et al., 2004) As we can see from Figure 2, more than a half of energy is consumed by an aeration process. Aeration is essentially required in biological treatment phase for mixing wastewater and oxygen supply for microorganisms. ...

... performance of the collector depends greatly on the amount of incoming radiation, collector area, tilt angle, orientation and overall efficiency of the system. (Gajbert, 2008) The produced thermal energy can be directly used for domestic hot water production, or, alternatively, stored in thermal energy storage. From the storage, thermal energy can be discharged according to demand. ...

... second one, in Kilmeena, is described in Figure 11. Another Irish solar WARES project -the Achill Island Central project -is shown in Figure 12. ...

... heat recovery from wastewater could provide a considerable option for generating renewable energy on the site of a water utility. (Intelligent Energy, 2007) The potential annual amount of thermal energy in wastewater can be evaluated by equation (2) The Equation 1 gives a simple tool to evaluate the potential in theory. Still, the equation does not take into account that the amount of produced wastewater varies hourly, daily, monthly and annually. ...
