How can you remove sodium from drinking water by Ultrafiltration process?

Answer 1

There are two ways to remove sodium from drinking water--ion exchange and reverse osmosis. Ion exchange uses a special resin that's formed into beads. You pass water through a cartridge full of these beads, and the resin exchanges the sodium in the water for the potassium in the beads.

The other way is reverse osmosis. There's a membrane in the reverse osmosis machine. When you pump water at high pressure up to the membrane, the water goes through without the sodium ions in it. Needless to say, the ion exchange cartridges are cheaper, but reverse osmosis works better because it strains out all sorts of other things too. Reverse osmosis works so well you can put dirty, germ-infested sea water into the machine, like the Army does, and get clean, safe drinking water out of it.

Answer 2

Ultrafiltration is not effective for removing sodium from drinking water, as it is a small ion that can pass through the membrane. To remove sodium, reverse osmosis or distillation may be more suitable methods as they can effectively filter out dissolved ions like sodium from water.
