| description | This
study aimed to prepare ceramic membranes from low-cost materials for oil/water
separation. TiO2 was incorporated into fly ash/kaolin-based ceramic
membrane matrix via the impregnation method to enhance membrane performance.
The scanning electron microscope (SEM) results exhibited random distribution of
pores along the membrane surface with an estimated pore size of 0.001- 0.13 µm.
The porosity of the TiO2-incorporated fly ash/kaolin ceramic
membrane ranged from 42.82%-50.22%, where the sintering temperature played an
important role in the water absorption and porosity properties. The X-ray
diffraction (XRD) pattern showed an orthorhombic kyanite phase with the
presence of three characteristic peaks at of 26.30°: 27.87° and 35.90°. The
XRD pattern of all formulated membranes showed almost no change, however, the
crystal intensity varied due to the different ceramic compositions. P hysicochemical
properties evaluation showed that the membrane with fly ash, kaolin, and
alumina of 20 : 30 : 40 wt% has reached the best characteristic. The casted
membrane with a compaction pressure of 30 bar with sintering temperature of
1200oC for 7 h had the highest compressive strength. The performance
showed that the TiO2 incorporated membrane achieved over 95% oil
rejection efficiency and significant decrease of several parameters such as Pb,
Fe, Mn, nitrate, nitrite, total dissolved solid (TDS), Cl and total organic
matter without sacrificing the permeate water flux up to 116 L/m2/h.
These experimental results suggest that the TiO2-incorporated Fly
ash/kaolin ceramic membrane has great potential for reclaiming oily wastewater
into clean water. |
