This document presents information on solar thermal desalination. It introduces different desalination techniques such as multi-stage flash desalination, multi-effect desalination, reverse osmosis, and forward osmosis. Multi-stage flash desalination produces about 60% of desalinated water worldwide by flashing sea water into steam in multiple heat exchangers. Multi-effect desalination uses multiple effects where steam heats and evaporates water in successive stages. Reverse osmosis uses the natural process of osmosis to move solvent from a lower concentration to a higher concentration area. Solar desalination has advantages as the solar energy source is free, making water production affordable, and it is an eco

2. INTRODUCTION
• This project is all about the Most contemporary
strategies against a “Global Water Crisis”
• This project provides a way of cleaning water(sea water)
on small or large scale for various types of uses. Like
solar water desalination plant.
• This solar water desalination technique have been
employed by mankind for thousand of year. But In 1870
a swedish engineer walton evens develop the first direct
method of solar desalination to get a fresh water.

4. DESALINATION TECHNIQUE
• MULTI-STAGE FLASH DESALINATION
• MULTI-EFFECT DESALINATION
• VAPOR COMPRESSION
• REVERSE OSMOSIS
• FORWARD OSMOSIS

5. MULTI-STAGE FLASHDESALINATION
• MSF IS WATER DESALINATION PROCESS THAT
DISTILLS SEA WATER BY FLASHING A PORTION
OF WATER INTO STEAM IN MULTI-STAGE OF
WHAT ARE ESSENTIAL COUNTERCURRENT
HEAT EXCHANGER.
• MULTI-STAGE FLASH DESALINATION PRODUCE
ABOUT 60% OF ALL DESALINATION WATER IN
THE WORLD.

8. MULITI-EFFECT DESALINATION
• MED IS DESALINATION PROCESS OFTEN USED
FOR SEA WATER DESALINATION. IT CONSIST
OF MULTI EFFECT.IN EACH STAGE THE FEED
WATER IS HEATED BY STEAM TUBES. SOME OF
THE WATER EVAPORATES AND THIS STEAM
FLOWS INTO THE TUBE OF THE NEXT STAGE,
HEATING AND EVAPORATING MORE WATER.
• EACH STAGE USE THE ENERGY FROM
PREVIOUS STAGE.

11. REVERSE OSMOSIS
• RO IS WATER PURIFYING TECHNOLOGY THAT
USE THE SAME TECHNIQUS OF OSMOSIS i.s
THE SOLVENT NATURALLY MOVES FROM AREA
OF LOWER CONSENTRATION TO THE HIGHER
AREA CONSENTRATION.

14. ADVANTAGE OF PROJECT
• DESALINATION TECH CAN BE USE WITH THE
COMBINATION OF MY POWER PLANTS FOR
THE GENERATION OF POWER.
• AS SOLAR ENERGY IS FREE OF COST THE
PRODECTION OF ENERGY IS AFFORTABLE
• DESALINATION TECHNOLOGY LEADS TO THE
SUSTANABLE DEVELOPMENT
• MOST IMPORTANTLY IT IS ECO-FRIENDLY
