Title: ZEOLITE MEMBRANE AND METHODS OF MAKING AND USING SAME FOR WATER DESALINATION
Abstract:
A novel zeolite membrane is manufactured using zeolite seeds that are deposited on a support material. The seeds are then further grown in a secondary growth step to form a membrane with inter-grown particles. The pore size of the zeolite membrane is in a range between 3 angstrom and 8 angstrom, which allows water to flow through the membrane at a relatively high flux rate while excluding dissolved ions. The novel zeolite membrane is surprisingly efficient for desalinating sea water using reverse osmosis. The zeolite membrane is capable of high rates of water flux rate and high percentage of ion rejection.
