  • Asymmetric forward osmosis membranes
    Patent number: 7445712
    Abstract: There is disclosed a membrane formulation having high flux for forward osmosis applications. There is disclosed a forward osmosis filtration membrane having a salt rejection 99+% or greater, and comprising an asymmetric hydrophobic porous backing and cellulosic fibers. The membranes of the present invention find use in a variety of applications including osmotic-driven water purification and filtration, desalination of sea water, purification of contaminated aqueous waste streams, and the like. Specifically, there is disclosed a forward osmosis filtration membrane having a skin layer for salt rejection and a porous scaffold layer having a woven or non-woven mesh embedded within it.

  • Forward osmosis pressurized device and process for generating potable water
    Patent number: 7303674
    Abstract: There is disclosed a process and device for Forward Osmosis (FO) Pressurized Device (FOPD) in general and one hydraulically coupled to a reverse osmosis (RO device for a FOPRO (Forward Osmosis Pressurized Reverse Osmosis). Specifically, there is disclosed a passive device (that is, not needed energy input) for using forward osmosis to generate significant hydraulic pressure that can be used to drive a reverse osmosis process, wherein the reverse osmosis process (not needed external energy to run pumps) can separate salt from salt water to generate potable water from water with high salt content (such as sea water, urine, sweat, brackish water and the like).
