    Etude physico-chimique des margines issues de différents modes de trituration de quelques variétés d’olives dans la région du Ghardaïa
    (Faculté Science de la Nature et de la Vie et Sciences de la Terre - Université de Ghardaïa, 2019) MOULAYABDELLAH, Hakima; MAATALLAH, Sara
    The purpose of this work is to study the physico-chemical and bacteriological parameters of the margins of three olive varieties from two extraction systems: traditional and three-phase centrifugation. Physico-chemical analysis are carried out on the margins: (pH, turbidity, conductivity, temperature, humidity, organic matter, dry matter, mineral matter, calcium, magnesium, chlorurer, DBO5, total sugar). They showed that these effluents overloaded with organic matter evaluated in terms of DBO5 (66 g O2/l.). They are also characterized by an acidic pH (4.60-5) and very high conductivity (14.58 ms/cm). and richer by mineral elements: calcium (120.24mg/l). Magnesium (340.20mg/l). Chloride (142mg/l).the higher margin humidity (98.08%).The results obtained show that these margins are very humid, acidic and overloaded with organic matter.
