Management of Wastewater Collected from Craiova Municipality in Accordance with Directive 91/271/2002 CEE

Meeting the ever-increasing needs of water for domestic, industrial, energy, and agriculture, is getting more and more difficult, due to the fact that water, both groundwater and surface waters are becoming more polluted, this being mostly due to industrial development, population growth, etc. European Council Directive 91/271/2002 transposed by Government Decision 188/2002 is the legal basis of community legislation on wastewater.The biological treatment process uses the metabolic activity of a group of organisms able to degrade organic matter to carbon dioxide and water (Robescu, 2008). In order to protect the environment, primarily the emissary, as well as the soil and air, a proper process of treatment should provide favorable conditions for further possible use of such water for domestic, industrial or agricultural activities (Banu, 2007).
