solar powered borehole coupled with an ultrafilrer

This method involves the construction of a borehole with a pump that uses solar energy to power it. The pumped water is plunged upwards into a reservoir tank after passing through four ultra filters which are installed near the tank. A small tap connected to a pipe coming from the tank is used for easy access of the water. The ultrafilters ensure removal of disease causing pathogens before the water enters the tank. this ...more »

local solar disinfection

This simple technique requires only a few plastic bottles and sunlight. Firstly, collect several bottles (0.3 to 2.0 litre) made of clear plastic, remove all labels and wash them thoroughly. Fill the bottles with water of low turbidity and shake for about 20 seconds to aerate the water. Expose the bottles to the sun by placing them on a roof or rack for at least six hours (if sunny) or two days (if cloudy) . The water ...more »

Artificial leaf makes clean energy from dirty water

If one day in the not too distant future you can go to the dollar store, buy a thin, flat device the size of a playing card, dunk it in a quart of dirty bath water and use it to generate about 100 watts of electricity 24 hours a day, you can thank the Air Force. Along with other federal agencies, the Air Force Office of Scientific Research has been pouring funds into the development of an “artificial leaf,” a low cost ...more »

SOLAR DISTILLATION

Not to be confused with solar sterilization or disinfection, solar distillation purifies even muddy, salty or otherwise undrinable water through evaporation and condensation. The power of distilation to purify saltwater makes it unique among the treatment methods featured on this page. A solar still can actually be a cheap and simple piece of shaped plastic or glass, or they can be more highly designed devices. To work, ...more »

Solar Powered Ultraviolet water treatment Device

SOLAR POWERED ULTRAVIOLET WATER TREATMENT DEVICE Introduction Ultraviolet or UV energy is found in the electromagnetic spectrum between visible light and x-rays and can best be described as invisible radiation. In order to kill microorganisms, the UV rays must actually strike the cell. UV energy penetrates the outer membrane, passes through the cell body then disrupts DNA stopping reproduction. UV treatment does not ...more »

Solar Powered Water Purifier

Using the sun to purify drinking water is a great solar project for the do-it-yourself. A solar-powered purification system the size of a microwave oven can yield up to 3 gallons of purified drinking water on a sunny day. Here’s what you need for a basic solar powered water purifier like the one shown in the figure: Wooden or sheet metal enclosure Reflective material like aluminum foil Black paint, used for barbeque ...more »

Got a Smartphone?.....treat your water

This simple idea is based on the use of Ultra Violet light probe powered by your phone battery.

You will insert the probe cord in to the phone charging port just like you would do for charging.

Once the probe gives light........Just insert it into your glass of water for at least 10minutes.......then drink the water.....it was treated in the 10minutes and 99.9% of water borne pathogens are long dead!!!!

SOLAR STERILAZATION.

Solar sterilization If cost is a bigger concern than time or convenience, the cheapest way to treat water is to leave it in a plastic bottle in the sunlight. Leave clear bottles in the sun for a few hours and the UV radiation and heat kills the microbes that cause diarrhea and other waterborne illness. The Sodis (for solar disinfection) method was deployed in some parts of Haiti after the earthquake in 2010, and it is ...more »
