Comparison of retort water treatment methods – a case study in Jordan / Jämförelse av förbehandlingsmetoder av spillvatten från pyrolys av oljeskiffer – En fallstudie från Jordanien
In this work, physical and chemical characterization of El- Lajjoun retort water from oil shale pyrolysis process has been carried out. Comparison of different treatment methods (Air stripping, activated carbon, and oil shale ash) for the major components which could affect the design and operation of any set of wastewater treatment process were conducted. The removal of phenol and ammonia using activated carbon after 12 h resident time were 93 and 41 %, respectively. The activated carbon reduced the total organic carbon (TOC) and the chemical oxygen demand (COD) regardless of residence time. Using activated carbon as adsorbent proved to be effective for the treatment of high percentages of phenol and ammonia from retort water. On the other hand, air stripping was found to be a very effective method for removing ammonia from the retort water.
