The present work reports the application to reduction of the organic matter and nutrients in oil mill liquid waste (OMW), using the natural calcium bentonite from Morocco as adsorbent. The margine is characterized by a high concentration of low biodegradable and highly toxic organic matter. In order to evaluated the reduction capacity of bentonite to remove organic matter and nutrients, characterization mineralogical, chemical and also morphological of adsorbent were conducted. During the experiment and in the scenarios studied, all the total of parameters adsorbed was strongly depend on the percentage of bentonite. While, the percentage of pH of OMW was gradually decreased from 4.03 to 8. 04. The COD concentrations were decreased from 172.72 to 29.71 g/l, and also the phosphorus concentrations were decreased from 1.16 to 0.29 g/l. The electrical conductivity decrease in this work from 16.93 to 0.17 mS/cm. This present work proves that calcium bentonite is an effective adsorbent for the elimination the nutrients and organic compound.
