Abstract

In the present investigation, a low-cost ceramic microfiltration membrane was fabricated by using inexpensive raw materials through paste casting technique. The membrane was cast in the shape of a circular disk of 73 mm diameter on a metal plate by using local river soil, sodium hydroxide, sodium nitrate, oxalic acid and chalk powder. Initially, the paste was prepared by mixing the precursor materials in a predetermined proportion with the help of 1 M and 3 M NaOH solution. The casting process was followed by sintering at 970 °C and subsequent activation at this temperature for 30 minutes. Then the prepared membrane was allowed to cool down to room temperature in order to provide strength. The porosity of the prepared membrane was determined by pure water permeability test and it was found to be 0.43 whereas the permeability of pure water was evaluated as 3 × 1068 m3/m2-kPa-s. The compressive strength of the prepared membrane was calculated as 2.32 MPa. The cost of the prepared membrane was estimated to be 13.64/membrane respectively. Therefore, in the present study, a low-cost ceramic membrane had been effectively developed which could be used to remove various water pollutants from wastewater.
