Note that most of the desalted water will eventually get back to the ocean as sewage and seepage.

The first source of water to treat is treated sewage, as it is already low in salt. Then, turn to the ocean if available.

James, that’s an important environmental issue that desalination scientists are dealing with. Concentrated seawater can damage marine ecosystems. Tom Pankratz told me that desalination plants mix the salt into the water as quickly as possible to dilute it and minimize the impact.

The problem with the traditional method of boiling water and saving and cooling the evaporate was that the desalination plant would also release a lot of hot water back into the sea. And as they drew seawater in, the desal plants would sometimes take in marine animals. Now plants are built with equipment to stop that from happening. But the major engineering problem is still the huge amount of energy that the desalination process uses.

So the environmental concerns with desalination are many, and that’s why scientists are working so hard to improve their methods.

If the more salt particles are left bact to the sea, is it possibly caused salt desnsity too high in the sea and destroy the oceans ecosystem?

I hope this will work but then agin I don’t hopefully you are susessful with the technology you have it should work
