Investigation of breakthrough point variation using a semi-industrial prototype packed with low-cost activated carbon for water purification

Abstract

The present study was initiated to determine the limit operating conditions of a pre industrial prototype packed with Borassus Aethiopum activated carbon for water concentration (38.48; - purification in rural areas. To do this, the influence of nitrate NO3 76.61 mg/L) related to the season (dry or rainy), the flow rate (2; 3 L/min), the mass of activated carbon (260; 300; 380 g) and the height of the filter (15; 20; 25 cm) bed was evaluated. Physico-chemical characterization of the activated carbon prepared has shown /g ) with both micro and mesoporous pore structure. 2 a high specific surface (1434.60 m For dry season (38.48 mg/L) using Kloze model, the respective breakthrough times of 405.83, 638.38 and 956.67 min were obtained against theoretical times of 420, 630 and 945 min. As for rainy season (76.61 mg/L) predict breakthrough times 332.5, 653.33 and 952 min were found against 315, 525 and 945 obtained theoretically.
