Experimental design and modeling of removal of organic matter and nutrients in the OMW by calcium bentonite

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