Question

What is the cheapest and most effective way to filter out the Salt from sea water.?

Answer 1

salination is the only way, i think

Answer 2

One technique that shows promise for small-scale desalination is called humidification-dehumidification (HDH), in which a stream of hot air is humidified to saturation point by bubbling it through salt water. This air stream is then cooled causing pure water to condense out of it.

Also, a water desalination system using carbon nanotube-based membranes could significantly reduce the cost of purifying water from the ocean.
