METHODS OF WATER

PURIFICATION

Life Straw◦ The Lifestraw is a small cigar-

shaped tube. This clever design purifies water from potential pathogens like typhoid, cholera, dysentery and diarrhea – all before they reach your lips. The Lifestraw is an inexpensive way to deliver potable water to those in need, and it is considered an icon of humanitarian product design

Ceramic Water Filters

◦ Developed in a joint effort between WSP and UNICEF, the filters are made from fired clay, and the tiny pores of the ceramic material are small enough to remove virtually all bacteria and protozoa. The design utilizes gravity to facilitate the filtration process, resulting in a flow rate of 1-3 liters per hour.

Water Purifying Bicycle◦ The Cycloclean harness kinetic energy to purify water, and users can ride the bike to any nearby body of water for immediate access to a source of potable drinking water.

Life Sack

◦ To filter contaminated water the Life sack uses SODIS (Solar Water Disinfection Process) technology: UV-A-radiation and the bag’s thermal treatment process work together to kill deadly microorganisms and bacteria in water. The sack can also be worn as a backpack for quick and easy movement from the source to the community.

“Pure” Water Bottle Filters◦ Pure Water Bottle – a device that

is capable of filtering soiled water in two minutes by using a combination of 4 micron-sized water filters and a wind-up ultraviolet light system. This combinations removes up to 99.9% of impurities from any water source, and it could be a valuable asset for people in developing nations.

Eliodomestico

◦ Eliodomestico requires no motors or electricity. Pour water in the top and leave in the sun for 8 hours and your water will be purified.The heat from the sun casues the steam to rise up and go through a watertight boiler that releases the steam through a separated expansion nozzle where the steam collects.
