Wastewater treatment using constructed wetlands Tirana, Albania

The pilot plant, one of the first established in Albania, consists of a "Dortmund tank" (a settling tank with vertical flow) combined with another settling tank for pre-treatment, two vertical filter beds that are fed alternately by pump and one horizontal filter bed. Effluent is collected for reuse purposes. For sludge treatment, a planted sludge drying bed was implemented. The total area used for the plant is around 1,600 m2.

As several problems with plant operation occurred in the beginning, reconstruction works were done in 2010. After a site visit and sample taking in the end of 2011, it can be stated that the plant is working very well at the moment.
