What is the byproduct of desalinization? How much usable materials could be gleaned from this process?
Sea Salt.
I think the Saudis have plants that virtually give away the sea salt. It is then loaded on ships and brought all the way to places like Portsmouth, NH. There it is off loaded and used for deicing the roads in the winter. However, municipal and residential water treatment systems require salt to treat their water either to kill bacteria or soften hard water. So, there is a market for it.
FYI, our company sells about 700+ truckloads of bagged rock salt, calcium chloride and magnesium chloride/year in the winter for melting ice/snow.
Salt, which theoretically has uses on icy roads.
I'm thinking sea salt.........which is all the craze now for salty snacks.
Water that is more salty. They don't produce dry salt; they separate some of the water from the salt water stream, leaving a flow that is more salty back to the ocean.
