Who discovered Desalination?
Where is desalination done
In 1791 Thomas Jefferson(America) invented the earliest stage of desalination where he describes the simple desalination process. The process was printed and put on the back of board ships so that they could drink fresh water in case of an emergency.
Where was the first desalination plant built?

First LTTD plant opened in 2005 at Kavaratti in the Lakshadweep islands. The plant's capacity is 100,000 litres.The plant uses deep water at a temperature of 7 to 15 °C
The countries who desalinate water are Algeria, Aruba, Australia, Bahrain, Chile, China, Cyprus, Egypt, Germany, Gibraltar, Grand Cayman, India, Iran, Israel, Malta, Maldives, Oman, Saudi Arabia, Spain, South Africa, United Arab emirates, United kingdom, United states, Trinidad and Tobago.
Can desalination help save the environment
Ocean desalination hides the growing water supply problem instead of focusing on water management and lowering water usage. It will practically drain all resources in the next 30 years. We need to find an alternate solution to this.
What is the cost to make a desalination plant?
Example: Victoria Desalination plant
Cost to build:
Estimated to be $2.9 billion initially
Estimated time to build: 25-30 years
Operating charges: $1.5 billion :
This includes labour, replacement of membranes, chemicals costs and energy, and were initially estimated at $132 million per annum

WHAT IS DESALINATION
Desalination is the removal of salt and other impurities from seawater to produce fresh water. Many countries are using desalination as of way to have a more reliable way to have fresh water. It basically like reverse osmosis, which involves forcing water through semi-permeable membranes to remove salts and other impurities. It is also called desalting.
Desalination
Pros & Cons
Pros:
1. Can provide drinking water to people
2. Produces salt aswell.
3. Doesn't use fresh water resources.
Cons:
1. Only rich countries can afford desalinationn
2.It will drain oceans, killing marine life .
