Desalinization

You need a way to boil the water and allow the condensation to collect in a condensation coil that leads to a container holding the water

The simplest way is to use the condensation method where you place the salty water in a container and heat it, normally using the sun. Water vapour will evaporate off and is captured by condensing on something colder ( a tube , plastic sheet, whatever is available. This fresh water is then allowed to run down in droplets until captured in a bottle.

Basically, desalination of water can be carried out by the following general methods:

1. Distillation

2. Electrodialysis

3. Demineralisation/Deionisation and

4. Reverse osmosis.

Building a desalination plant typically takes anywhere from 1 to 3 years, depending on factors such as the project's size, technology, location, and regulatory approvals. Smaller, modular plants may be constructed more quickly, while larger facilities may require more extensive planning and infrastructure. Additionally, unexpected challenges such as environmental assessments and financing can impact the timeline. Overall, thorough planning and efficient management are crucial for timely completion.

on a normal pressure (1 atm) water boils on a temperature of 100 C, but when we reduce the pressure, ebullition temperature will be also reduced (it will become less then 100) which means that they can boil more water using less energy

There are a great number of techniques for desalinization of water, and many of them are quite primitive. They have been around for a long while. So there is no single answer for this question.

Because of the cost, it is much easier to use our fresh water resources.

Anything which will heat the water, so could be oil, natural gas, nuclear, or other means of getting heat.

Depending on the size of the desalination plant and where it is being built it can cost Millions of Dollars to buid but seem to produce very clean water for between US$0.49 and US0.53 per cubic meter. The costs are coming down, the quality is going up and the choises available are getting wider.

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.

it is practical, but energy consuming

Australian cities are planning to build desalination plants to get more water ready to use instead of waiting for it to rain

Something to do with water.

Desalination is the process of removing salt and other impurities from seawater to make it suitable for drinking or agricultural purposes. This is typically done through methods such as reverse osmosis or distillation to separate the salt from the water, providing a source of fresh, drinkable water in regions where freshwater resources are scarce.

Desalination, the removal of salts from sea water using primitive methods of distillation, has taken place over thousands of years. There are biblical references as well as historical accounts from ancient Egyptian, Phoenician and Greek writings, mentioning the purification of brackish water. 17th Century Japanese sailors used earthenware pots to boil seawater, and bamboo tubes to collect condensed fresh water from the steam. A technical report on desalination was presented by Thomas Jefferson, then US Secretary of State, in 1791 to describe the results of a simple distillation process.

This is a very good idea as it is cheaper and better for the environment. The only problem is that we do not have the technology yet to be able to apply this to support an entire city let alone town. It will be many years before we have the technology feesable to do this.

Yes. The Earth's water is running out and we need new ways to take water and make it fresh. There are many forms of desalination, but many are very expensive. Less than 1% of the Earth's water is fresh and many people are polluting the very little water we have.

how to design a desalination plant of 2000 tonnes per day production of distillate ,the desalination type of evaporation multi stage ,,with material balance,?

3 types of desalination are:Electrodialysis, Distillation and Reverse Osmosis (RO).
