Surfactant-polluted surface water treatment with Moringa oleifera seed extract

Moringa oleifera seed extract has been tested in removing surfactants from polluted surface water. River water has been polluted with sodium lauryl sulphate, a spread surfactant, and Jar-test have been carried out in order to evaluate the effciency of this natural coagulant agent inside a real surface water matrix. Effciency has demonstrated to be very high (maximum q of about 2.5 mmol·g⁻¹) and a high surfactant removal is achieved rapidly. Coagulation process may be modelated through Gu and Zhu adsorption hypothesis, so an acceptable r² coeffcient is obtained (0.94).
