STUDY OF OXIDATION/DISINFECTION STEPS OF TREATMENT PLANT OF AIN TINN (MILA, EASTERN ALGERIA)

S. ACHOUR, F. CHABBI

Abstract


Disinfection / oxidation is an essential process for the production of drinking water, safe for the health of consumers. The aim of this study is a description and focuses on the oxidation / disinfection steps in the treatment plant at Ain Tinn (Wilaya of Mila, East of Algeria).

This treatment plant has benefited from various oxidation techniques (ozone, permanganate ...) in addition to the final chlorination.

Tests on the raw water supplied to the station from the Beni Haroun dam revealed that the quality of the water was often average to poor, particularly with regard to anthropogenic pollution.

Tests on filtered treated water before final disinfection showed that parameters such as organic matter, ammonia or bromide appeared to be little eliminated by pretreatment and the clarification phase.

During the chlorination tests, high chlorine demands were observed indicating a complex mineral and organic composition of the waters tested. However, chlorination of filtered water results in lower chlorine consumption and indicates that the clarification treatments prior to final disinfection should be more optimized in order to minimize the chlorine / organic matter reaction.
