This investigation focus on the application of surfactant enhanced aquifer remediation (SEAR) technology using
modified surfactant to improve the remediation of olive oil mill wastewater (OOMW), a new kind of surfactant was used
which is a new extended surfactants sodium polypropylene oxides sulphate of the type (branched hydrocarbon chain)-
(propoxyle group)-(sulphate). A modelled three dimensional phase diagram using phenol as a model compound for the
phenolic compounds in the OOMW was determined and the amounts of the surfactant needed to extract the phenol can be
determined using the three-dimensional phase behaviour of the phenol, water and the proposed surfactant. 1
H-NMR and
direct photometric method was used for the detection of the efficiency of the surfactant in the remediation of OOMW.
