What piece of equipment can be used to separate sand from water and salt?

Answer 1

The easiest would be to use: two glasses, distilled water and a burner. 

Put your sand-salt mixture in a glass and add water. Water will dissolve the salt, while sand will stay unchanged. 

Pour the water (now it is salt solution) into another glass. Heat the second glass (with the salt solution) until all the water evaporates. 

Now you are left with two glasses:

The first one contains only the sand, while the second contains only the salt.

Answer 2

Water purification is a process of removing undesirable chemicals, materials, and biological contaminants from raw water. Desalination, desalinization, or desalinisation refers to any of several processes that remove excess salt and other minerals from water.

There are two systems for Desalination. The distiller aparatus and the reverse omosis aparatus.

Answer 3

The apparatus would be a distillation system, such as a "solar still."

If you place a cup of salt water in a closed container, and put it in the sun, water vapor will evaporate from the salt water and condense as pure water on the walls of the container.

Answer 4

Saltwater is a solution, not a mixture, but it's pretty easy to separate. The equipment you want to use depends on how fast you need it to go. If you've got a lot of time, just pour the saltwater into a shallow container and allow it to evaporate. If you need it pretty quickly, put it in a metal pan and boil it dry...if you would like, you can construct a device to collect the steam.

Answer 5

You would boil the water off.

Answer 6

distillation apparatus

Answer 7

Slow sand filter

Answer 8

Its a hot plate

Answer 9

A simple method is distillation.
