PROJECT SUMMARY:

we develop a portable solar powered se water desalination as well as water purifier to solve the water problem with a smart innovative concept.we develop a portable solar powered se water desalination as well as water purifier to solve the water problem with a smart innovative concept.

Only 3% of the water available on earth is fresh water. Two thirds of this fresh water is present in frozen glaciers. On an average over 1.1 billion people over the globe lack proper access to any fresh water reserves and over 2.7 billion people face scarcity of water at least once a month. But fortunately as we know 71% of earths surface is water and 97% of that water is sea water.

So here we develop a portable solar powered se water desalination as well as water purifier to solve the water problem with a smart innovative concept.

Project Objectives

PROJECT OBJECTIVES:

• Fast Water Desalination.
• Instant Purification of desalinated water using RO system.
• Added UV sterilization for virus bacteria sterilization.
• Compact Design.
• Portable Design Easy to Move.
• Solar Powered – No External Power. Needed.
• Easy Maintenance System.

Project Implementation Method

PROJECT IMPLEMENTATION METHOD:

The machine makes use of a 3 stages process to convert salty seawater to pure drinkable water. The system first allows user to pour salty water via a mesh based inlet where large waste like plastic granules or stones, weed etc. gets separated. This water is then pumped into a large purification chamber having 3 layers of purifiers including sand and gravel for filtering weed, sand and large salt particles.

The output of this process is still salty water but without any particles. This water is then passed on to the second filtration where we use reverse osmosis to filter out salt from the water. Here we use 3 filtration membranes to filter out fresh water from salty water and trap the salt particles in membrane filters.

This water is now stored in a tank just above the system. The system tap when opened allows water to run from the tank to the tap where we detect the flow when on and turn on the UV light for stage 3 filtration to deactivate any remaining bacteria and virus in the water. This water is now in drinkable form using 3 stage process without the use of any chlorine.
Now the pumps used in the system are powered by a large battery. This battery is in turn charged by 170 Watt solar panels due to large availability of solar power in sea areas. This makes it very portable to be used on any beach front or on long sea voyages for easy and instant sea water filtration.

Benefits of the Project

BENEFITS OF THE PROJECT:

4. To provide 30-45 gallons of water in 24 hour.
5. Instant Purification of desalinated water using RO system.
6. Added UV sterilization for virus bacteria sterilization.
7. Compact Design.
8. Portable Design Easy to Move.
9. Solar Powered – No External Power Needed.
10. Easy Maintenance System.

Technical Details of Final Deliverable

TECHNICAL DETAILS:

Reverse osmosis removes contaminants from unfiltered water, or feed water, when pressure forces it through a semipermeable membrane. Water flows from the more concentrated side (more contaminants) of the RO membrane to the less concentrated side (fewer contaminants) to provide clean drinking water.

It is deliverable because, From this exhaustive literature review, it is found that various methods are developed for distillation of water. These methods are subject to the demand of fresh water, quality of water source and the involved expense. Conventional Reverse Osmosis systems are currently prevalent domestically but at the cost of plenty of waste water. Non-conventional water purifiers like solar stills have unlimited potential , so their usage is adequate for our output rate thankyou.
