By desalination of sea water for drinking purposes will not alter the balance between sea and land?

Answer 1

No.

The total amount of salty ocean water is so large that what little could be desalinated for use by humans would be very small in comparison.

The oceans contain about 1,340.7 million km3 of water, making up 1/800th of the total volume of the Earth. Fresh water for human use (about 18,200 km3) would literally be a "drop in the bucket."

Answer 2

No, Never !The Ocean was created to keep ecological balance. If you desalinate then how much drinking water do you require ? Nothing in comparison to the huge reservoir of water of ocean. On the other hand what we drink or waste the same water is returned to the Ocean through cycle( cloud/ rain). The salt stock also will not concentrate or reduce considering its Vastness.Hence alteration of balance between the land and the sea does not arise.

Answer 3

Almost unlimited quantities of sea water are available to coastal areas, and brackish waters containing salt levels too high for most uses are available in many aquifers and inland seas. The cost of desalination depends on the quantity of salts removed. It is less expensive if the process starts with brackish water -- with salt concentrations well below the 35,000 parts per million characteristic of sea water -- and if the finished water is not treated to meet drinking water standardsTechnological advances have reduced desalting costs. Still, desalination of sea water today costs about $1,800 an acre-foot, and is energy-intensive, making it a supply of last resort.There is ,therefore, no fear that sea water will be overdrawn even if cost of desalination further goes down.

Answer 4

I have to disagree with everyone here. Years ago, people thought the number of fish in the ocean was inexhaustable, so they just killed or caught as much as they wanted....now we face fish stock depletion because of overfishing.

The water cycle is just that...a cycle. If humans all over the globe start to desalinate the ocean, inevitably the cycle will become out of kilter. Where will all the sale from the desalination be returned to the ocean and what affect will that have on it's animal and plant life, and possibly the weather. We just don't know. And until we have a better idea, it seems to me crazy to start something that's potentially unstoppable and may have catastrophic consequences. Always err on the side of caution.

Answer 5

Desalination of seawater would defenitely produce huge quantities of salt and if the entire seawater is used for desalination then defenitely it would alter the balance. However, the quantity of seawater used for desalination and the available quantities of seawater would show that the desalination quantities are insignificant. However, at the places where these excess salts are disposed (mostly back at sea and away from seawater intake) would defenitely show an increase in salinities. But proper method of disposal would reduce the effects on the surrounding environment.

Answer 6

Desalinization of water is actually a good thing since you're taking water out of the ocean which may have come from melting Ice, Glaciers, Snow, and rain.

Answer 7

i have in my view worked on designing a desalination plant and there are countless rationalization why they don't look favourite. the biggest situation is means intake. as straightforward because it sounds, maximum desalination flowers use the tactic of evaporation of salt water (salt would not evaporate with the water). The water is switched over to sparkling-water steam it is cooled and picked up. imagine how a lot water is used with the help of a common city. the significant water traces into cities carry huge quantities of water that would want to might want to be evaporated. it truly is not any longer like it truly is not any longer attainable, it truly is basically very severe priced to construct, take care of and perform. yet another massive situation is sanitation. Lakes and wells are favourite because their feeder rivers might want to be managed. compared to the sea the position many parts nevertheless unload truly a lot of raw sewage. might want to you imagine ingesting out of something mixed with water from Boston Harbour, Halifax Harbour or the Nile River? back, no longer that it may't be executed, it basically makes you savour how straightforward a lake or a properly is in evaluation.

Answer 8

No, and it all goes back somehow anyways really. Whether it seeps into the ground and heads back to the sea, or it dehydrates and eventually turns to rain over the ocean.

Answer 9

I would not think so, because the amount of water used just for drinking is miniscule compared to, lets say, irrigation.

Answer 10

Hi,
Matter can be nither created nor destroyed , buy the use of humans too its still in balance.
