109 Picture 16.: Anaerobic digester fully operational inside the facilities The facility is usually closed during the weekend but electronic equipment (sensors) for the monitoring of the drying process operate inside the facility <strong>and</strong> the staff can access the control system from their houses so if anything goes wrong everybody communicate with each other so that the potential problem is solved with no significant cost. Thermal oil (Picture 17.). will be used as media to transfer the heat to the heat exchanger of the drier. Excess heat from the condensation process is also available to heat up the digesters transferred by a heat exchanger (60/40°C). Picture 17.: Power generator
110 The installation has different options for the h<strong>and</strong>ling of the sludge/product: ‣ discharge of the mechanical dewatered sludge to containers ‣ production of partially dried granules with 65 – 90% dry substance ‣ production of fully dried granules with 90% DS (main product route) A diagram with the drying process is shown in (Figure.33) Figure 33.:Drying process description diagram The plant dries 3500 tons/year of treated sludge <strong>and</strong> the total cost of the drying facility is approximately 16 ooo ooo euros while the total sewage treatment plant facility cost is 42 000 000 euros. The final product without the excess moisture <strong>and</strong> without the polluting odors is transported to incinerators for burning.
