Oilfield and refinery wastewater is heavily loaded with organic pollutants and is difficult to treat. This study explored using Moringa oleifera seed as a low-cost adsorbent to remove that organic content, using wastewater from an oilfield refinery in Iraq.
The team optimised the treatment by varying moringa dose, contact time and pH, and fitted the results to standard adsorption models (Freundlich and Langmuir isotherms).
Key findings
- Organic-content removal reached 89.65% under optimum conditions.
- The best conditions were a 1.5-hour contact time, 1.5 g moringa dose and pH 3.
- Adsorption followed the Langmuir and Freundlich isotherm models.
Caveat: a laboratory adsorption study on refinery wastewater; field performance depends on effluent composition.
