January 11, 2022
Share on 
In Wadi Echerka Bechima (Gabès –Tunisia), l’Institut de Régions Arides de Médenine, upgrades the existing pilot plant for water tertiary treatment through infiltration-percolation and tests an innovative filter bed made of clay.
The properties of clay as filter material have already been tested in laboratory filtration trials and are now used in the existing wastewater treatment system. The area of Wadi Echerka Bechima has an arid climate with a mean annual temperature of 31 °C and mean annual rainfall of 180 mm.
The MEDISS project in Tunisia is focused on achieving three primary objectives:
- Improve the irrigation water quality by using a pilot wastewater treatment system through an innovative infiltration-percolation method with different filtration mixtures;
- Raise awareness on the local farmers to use non-conventional water as an alternative for irrigation of agricultural land;
- Enhance the treated wastewater resources and enhance the water potential.
