A portable desalination device, as the name suggests, refers to a device that can be carried around, easily moved, and can desalinate seawater. It is usually designed in a compact form and is suitable for use by individuals, teams or small units in emergency situations, especially when fresh water resources are scarce at sea or in coastal areas.

Taking the reverse osmosis device with a daily output of 50 tons of fresh water as an example, its daily energy consumption is about 1000 to 1500 kWh. Calculated at 0.1 US dollars/kWh, the daily energy cost is about 100 to 150 US dollars.

Container-type design is a typical representative of mobile desalination units. This design uses a standard 20-foot or 40-foot container as the shell and integrates the desalination equipment into it, which has the following advantages:Convenient transportation，Quick installation，Strong flexibility.
