Improve Heavy Metals and Pollutants Removal from the Pharmaceuticals Wastewater Using Washingtonia Robusta: New Extraction Process

Abstract Jordan is one of the most water-scarce countries in the world. The country’s renewable water supply currently only meets about half of the population’s water demands. The aim of the present study was to investigate the changes in the level of heavy metals found in pharmaceutical wastewater from Al-Hikma Drugs Industry using palm fronds - Washingtonia Robusta (PF-WR) as organic adsorbents. Removal of heavy metals, turbidity, chemical, and biological oxygen demand, and suspended solids from industrial water using bioadsorbent materials was studied. Increasing the concentration of PFWR increased the removal efficiency. The optimum reductions of Fe, Ni, Cu, Cr, Pb, Co, Al, Na, COD, BOD, and turbidity were 64.29 %, 90.35 %, 61.75 %, 62.6 %, 60.60 %, 34.09 %, 10.09 %, 85.26 %, 87.41 %, and 78 %, respectively, were achieved by increasing the PF-WR concentration to 100 %. The removal efficiency was found to be concentration-dependent of PF-WR. The lowest reduction was achieved by sodium and pH.
