An empirical model using response surface methodology (RSM) is proposed to investigate the role of parameters, such as preparation pressure and binder contents on the porosity and flexural strength of a tubular low-cost ceramic membrane based on central compact design (CCD). Preparation pressure and binder contents are selected as input parameters to obtain controlled porosity with considerable strength of membrane. The optimum preparation pressure is found to be at 9.81 MPa with the sodium metasilicate and boric acid contents of 7.50% each providing a microfiltration range membrane. The optimization study reveals that the errors between the experimental and predicted values are below 2%. FESEM images clearly unveil a consolidated microstructure of the ceramic membrane. Acid-alkali test conveys that there is no major change in elemental composition due to the presence of binders in ceramic processing. The cost of the optimized membrane is estimated at approximately $332/m(2).
