Fresh drinking water
Poor countries can benefit from a limited amount of scientific technology. They do not have the resources to utilize higher levels of technology, but they can benefit from things that improve the quality of food production, health care, and sanitation.
Desalination is the process of removing salt from sea water in order to make drinking water. The method of doing this typically uses reverse osmosis. Distillation is sometimes employed, usually using vacuum distillation.
This is from Cole Hillhouse. Techology can benefit your career and personal needs by helping you at a job or even in schooling. Technology has came a long way.
3 types of desalination are:Electrodialysis, Distillation and Reverse Osmosis (RO).
The cost of desalination varies widely depending on the technology used, the scale of the facility, and local conditions, but it typically ranges from $0.50 to $3.00 per gallon. Reverse osmosis, the most common method, generally falls within this range. In some regions, costs can be higher due to energy expenses and infrastructure requirements. Overall, advancements in technology and economies of scale are helping to reduce these costs over time.
The desalination process converts ocean water to freshwater.

Desalination
Physics is used in desalination when understanding processes like osmosis, reverse osmosis, and thermodynamics, which are fundamental to desalination technology. These processes involve the movement of water across membranes under pressure differentials and the utilization of energy for separation, making physics a critical aspect of the desalination process.
Yes, desalination plants are generally expensive to build and operate due to the high costs associated with the technology and energy required to remove salt from seawater.
Cost of course depends on capacity and desalination method. Shoaiba Desalination Plant, Saudi Arabia, uses MSF Flash technology with a total output capcity of 128 million gallons per day. Cost 1.6 billion $US.
The desalinated water is more expensive but in many countries is absolutely necessary.
reverse osmosis
Salinization is the process by which a non saline soil becomes saline, as by the irrigation of land with brackish water, While desalination is the process to remove salts from seawater or soil. So the difference is that salinity is the concentration of salt in, for example water, desalination is the process of removing salts from the water.=P
