Solar SeaWater Desalination Machine With RO UV Purifier

Abstract - The availability of drinking water is essential for the survival all of mankind. Adequate amount of water resources are available on our planet but very few of them can be used for the purpose of drinking. A number of water purification methods have been put forth by researchers to purify brackish water and sea water. As water purification processes require some sort of energy source, and with the advent of renewable sources of energy utilization in various fields, a thorough review of solar powered purification setups is essential. An effort has been made to review all the available research and technology for water distillation using solar energy in this research paper. It is found from the literature survey that, a number of research setups and devices are available but are currently not being used due to high initial setup costs and limited technological awareness in the society. 

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.
The solar portable desalinator serves the following key aspects

  • 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

. Introduction Solar water purification is a relatively simple treatment of brackish (i.e. contain dissolved salts) water or sea water in to fresh water. Distillation is one of many processes that can be used for water purification and can use any type of thermal energy. Concentrated solar energy can be used to provide this thermal energy, in a sustainable and environmentally friendly option. In this process, water is evaporated; using the energy of the sun then the vapor condenses as pure water leaving behind the dissolved salts and dirt sediments. They are classified in two groups; (1) phase-change processes and (2) membrane process. Phase change processes can be further classified into multi-stage flash (MSF) distillation, multiple effect distillation (MED), vapor compression (VC), and membrane processes are further classified into reverse osmosis (RO), electro dialysis (ED). A review of research in the fields of Humidification dehumidification technology, Solar Still Setups and Reverse Osmosis plants has been undertaken in this paper, with a further goal to provide assistance in creation of new projects related to above topics, for production of low cost drinkable waterespecially in remote areas and regions with high poverty. Only a sustained effort by researchers can help in providing for an environmentally sound solution, to this rapidly growing need of providing of basic necessities to an ever growing population on this planet.

The machine makes use of a 3 stage 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 2 x 50Watt 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.

CONCLUSIONS 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 but their usage is inadequate due to lesser output rate. Humidification dehumidification process is the most appropriate option for fresh water production and combined system for simultaneously hot water production. The multi-effect distillation method can be used for mass production of fresh water. The detailed review reveals that there is a need to develop a hybrid system of water purification which can overcome the limitations of all existing water purification systems. 

 

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.
