EFFECT OF FLOCCULATION-ADSORPTION COMBINATION ON THE PURIFICATION OF SURFACE WATER: A CASE STUDY OF SIDIYACOUB DAM WATER, ALGERIAT. HADBI AND S. HAMOUDI ABDELAMIR
An increase in the amount of Natural organic matter (NOM) was observed over the last 10 to 20 years in raw water supplies, which has a significant effect on the treatment of drinking water. The most common and most profitable disposal methods of the NOM are coagulation and flocculation followed by sedimentation and sand filtration. Nevertheless, there are some organic compounds, which cannot be removed completely in a coagulation step. An alternative for better elimination of NOM was studied in this work. The use of adsorbents such as activated carbon and Bentonite as additives for flocculation significantly reduced the organic matter content.
