Gaseous emissions are emitted from various stages of treatment in a WWTP. Currently, in developed countries the energy required for wastewater treatment accounts for approximately 3% of the total electrical load.
Crete is the largest Greek island and the second biggest (after Cyprus) of the East Mediterranean. It comprises mixed and complex water supply systems that combine surface waters (water dams, reservoirs and springs) and groundwater (wells, spring water tapping). The island, which has to rely on its own water resources, is characterized by the lowest rates of annual precipitation in Greece.
The main objective of the project overall is related to the provision of safe, high quality water to the citizens and tourists of the cities of Heraklio, Chersonissos and Agios Nikolaos. Surface water from the Aposelemis dam is collected and transferred to the water treatment plant where advanced water treatment is provided.
Wastewater treatment projects are always challenging, but when upgrading of existing works is involved the challenge increases.
