<p>Waste water derived from olive processing is biologically treated by aerobic oxidn. in a double distn. process, and collected in tank below the honeycomb tower wherein the oxidn. takes place pref. with frequently repeated circulation, accompanied by air induced by a blower at the tower head. Organic particles in the water tend to agglomerate, forming a slurry or sludge. This charged water is delivered by a pump with a separate filter tank whose charge of silica sand and/or active charcoal biologically purifies the water for return to the oil mill or for discharge with the drainage system.</p> |
