Treatment of wastewater from oil refinery by adsorption on fluidized bed of stem date

Abstract EN

fluidized–bed adsorbed system was used to study the removal efficiency of oil and the total dissolved solids (TDS) from on oily wastewater.

Adsorption was developed using stem date.

The range of oil concentration used was (100-500ppm), and the range of [TDS] was (600  1500 ppm).

The effects of flow rate at (18  28 L/min), particle size of stem date (3-5 mm) and bed height (25-40 cm) on the adsorption efficiency of removal were studied.

The results showed that the removal efficiency reaches high percent about (71%) with decreasing particle size, volumetric flow rate and increasing bed height and initial oil concentration contained in treated wastewater.
