How seawater can be purified for human use without using desalination plants?

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.

Why are Australian cities planning to install desalination plants?
Australian cities are planning to build desalination plants to get more water ready to use instead of waiting for it to rain
Why is the building of desalination plants controversial?
The use of desalination plants is controversial. Two major concerns are:they use a lot of energy, which is supplied by coal-fired power plants. Apart from the pollution caused by these plants there are many who feel that they are not sustainable. That is, they cannot continue to operate without putting the environment and our future at risk.the water flowing back to the sea contains much more salt than normal sea water. It is also warmer. This can affect marine animals and plants that live near the desalination plant.
Why is desalination bad?
Desalination has very high energy requirements and since most countries with desalination plants do not have nuclear power, it results in the burning of lots of more coal. Additionally, the methods by which salt is removed from water create a resulting "salt-slurry" which is ejected as waste in to the original saltwater body. This salt-slurry makes the area around the desalination plant poisonous for the local sea-life.However, in almost every case, the positives of desalination outweigh these negatives.
How much does it cost to build a desalination plant?
desaltination plants cost alot of money to both run and build. It can cost up to millions, maybe even billions of dollars.
Why would countries use the desalination process?
Desalination is a process that removes mineralsfrom saline water. More generally, desalination may also refer to the removal of salts and minerals,[1]as in soil desalination, which also happens to be a major issue for agricultural production.[2]Salt water is desalinated to produce fresh water suitable for human consumption or irrigation. One potential by-product of desalination is salt. Desalination is used on many seagoing ships and submarines. Most of the modern interest in desalination is focused on developing cost-effective ways of providing fresh water for human use. Along with recycled wastewater, this is one of the few rainfall-independent water sources.[3]Due to relatively high energy consumption, the costs of desalinating sea water are generally higher than the alternatives (fresh water from rivers or groundwater, water recycling and water conservation), but alternatives are not always available and rapid overdraw and depletion of reserves is a critical problem worldwide. Quoting Christopher Gasson of Global Water Intelligence, "At the moment, around 1% of the world's population are dependent on desalinated water to meet their daily needs, but by 2025, the UN expects 14% of the world's population to be encountering water scarcity. Unless people get radically better at water conservation, the desalination industry has a very strong future indeed."[4]Desalination is particularly relevant in dry countries such as Australia, which traditionally have relied on collecting rainfall behind dams to provide their drinking water supplies. According to the International Desalination Association, in June 2011, 15,988 desalination plants operated worldwide, producing 66.5 million cubic meters per day, providing water for 300 million people.[5]This number has been updated to 78.4 million cubic meters by 2013,[4]or 57% greater than just 5 years prior. The single largest desalination project is Ras Al-Khair in Saudi Arabia, which produced 1,025,000 cubic meters per day in 2014,[4]although this plant in Saudi Arabia is expected to be surpassed by a desal plant in California.[6]The largest percent of desalinated water used in any country is in Israel, which produces 40% of its domestic water use from seawater desalination.[7]
What is the correct name for engineering plants that distill seawater into drinking water?
Desalination plants convert sea water into drinking water by distillation.
How much percent of Singapore's water usage is obtained from desalination of seawater?
Currently 100 million gallons of water a day comes from two desalination plants in Singapore. Together these can provide for 25 % of Singapore's water needs.
Why don't world engineers recognize that solar panels fail to provide sufficient energy and required pumping energy to overcome large seawater chemical potentials in desalination plants?
World engineers do not recognize that solar panels fail to provide sufficient energy and required pumping energy to overcome large seawater chemical potentials in desalination plants because there is still a possibility of doing so.
How many desalination plants are in Illinois?
Illinois does not need desalination plants. It has plenty of fresh water from Lake Michigan.
Why can't you use the sea water for cultivation?
Because without desalination the salt in the water would kill the plants.
What technology is used to purify sea water for human use without using desalination plants?
reverse osmosis
What water salt or purified helps plants grow?
purified
How many desalination plants are in California?
20
What level of salinity will plants not grow?
Plants grow in seawater e.g. mangroves. There are other flowering plants that grow in shallow seawater. Seawater is about 3.5 % salt. Water needs to be over 3.5 % salinity before plants cannot grow.
