ABSTRACT
The Edible-Oil industries in Egypt consume about 6000 m3/h of water. Effluents from
these industries accompany more than 6000 tons per year of edible oils , which are
actually lost due , either to lack of efficient treatments , or due to the in-efficiency of
these treatments. Many methods had been used for treatment of effluents , the
physical methods of which proved to be the best . The use of flotation as a technique
for treatment of such effluents is restricted by some special requirements for such a
technique . Many researches, thus , were done to overcome such restrictions , yet
they had not arrived to solution which could be considered as to be vital as a
solution. This research is , thus, a trial of new mode, with a clear objective to
discover a possibility of recycling the oil contaminated with the aqueous effluents
from the edible-oil industries, on a laboratory scale , as a step on a train of trials
which will follow . Results revealed the success of the first step to reach nearly
complete re-gain of the lost oil with those effluents, by the use a new mode of
distributors which was not common in use for such techniques and by some
modifications of the treatment processings steps by the flotation technique .
