SUBMITED TO- SUBMITED BY-MR. DEEPENDRA KHANDELWAL GAURAV ANANDHOD(ELECTRICAL ENGG.) JIET(ELECTRICAL ENGG.)

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.

TYPES OF WATER STORAGE

DESALINATION TECHNIQUE

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

MULTI-STAGE FLASH DESALINATION

• 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.

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.

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.

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
