Three different types of zeolite having pore sizes in the range 0.26‐0.74 nm, (NaP, NaA, and NaY) powders and membranes are synthesized with different Si:Al ratio on low cost clay alumina tubular support. The results of the permeation and separation studies showed that the NaP zeolite powder and membrane removes maximum As( III ) from the water solution (more than 80%) compared to other zeolites. The removal of As( III ) to achieve drinking water standard, by zeolite membrane, in a single step process does not seem to have been reported before the present investigation. These are the novelty achieved.
