Seawater is converted into distilled water through a process called desalination, which typically involves methods like reverse osmosis or distillation. In reverse osmosis, seawater is pushed through a semi-permeable membrane that allows water molecules to pass but blocks salts and impurities. In the distillation process, seawater is heated to create steam, which is then cooled to condense back into liquid water, leaving salts and contaminants behind. Both methods effectively reduce salinity, making the water safe for drinking and irrigation.
artificial sources of water can be either recycled water or converted water from sea
by portable I assume you mean potable, ie. drinkable. Sea water can be converted into fresh water by use of a still or a reverse osmosis filtering system. A still works by capturing the pure water that evaporates naturally or by heating the sea water. The moisture that evaporates leaves behind almost all of the dissolved minerals and ions so when it is captured it is fit to drink. Reverse osmosis is basically a very very fine (microscopic) net that when the water is forced through it, the dissolved materials (salt, iodine and sea-thingies) are trapped on one side.
There is lot of water on the earth in sea,ponds,etc. because of heating due to sunlight or other causes it is converted into steam and moves upward then after condensing it is collected in the form of clouds.

The water runs down hill. That's why all rivers lead to the sea.
There are many different ways. You can use a bucket (large or small), a basket (which is almost the same as a bucket), a shovel (which will probably not collect that much water), or you can just drink the water. All of these will work...Some better than others. It is up to you to figure out which method you find the most helpful/easiest.
