كفاءة استخدام الجفت كأحد مخلفات عصر الزيتون في استخلاص البولة من البول

الملخص EN

Wastewater (WW) is treated in sewage plants at highly expensive process without paying attention to the attributed loss of the beneficial raw materials to the soil.

this happens because plants reduce partially the mass pollutants associated with ww then the treated WW is used in land irrigation in order to enhance its productivity.

however, this enhancement does not often improve the quality of farms soil that consumes a great pile of fertilizers which creates a conflict between soil strengthening technology and ecology.

based on the fact that sewage contains valuable chemical reservoir, this article offers the development of feasible method with twofold of environmental value.

meanwhile this thriving technology relies on urea being extracted through creating proper fashioned adsorbent, which is a mw-activated surface of olive mill solid waste (Jift) without any additives, reacted with the urea molecules.

nonetheless, this reaction can be achieved only if the ultimate radiation conditions as energy and time are well controlled.

accordingly, the histological structure enhancement and chemical stability of the treated Jift were strictly evaluated to have the best conditions to absorb urea on its surface.

at this experience; the physics as kinetic and thermodynamic of this reaction have been studied.

according to the results; it is verified that the irradiated Jift efficiency used in impregnating urea from its solutions reaches saturation limit, with 85% recovery.

as well, the recovered material may provide the opportunity to improve soil quality and consequently, allows the Jift to play a sustainable role for its amendment.
