P&G Purifier of Water es una tecnología de purificación de agua en polvo empaquetada en un sobre de 4 g. Funciona como un imán de suciedad, sacando la suciedad y los contaminantes del agua sucia.
P&G packages use many of the same ingredients used in municipal water treatment systems. It provides a visible sign that the water is becoming cleaner, even in very turbid water, and this increases user confidence. It also provides residual chlorination so the water remains usable for about a day. The portability of lightweight packages makes them a viable option for distribution to victims of emergencies and natural disasters or in hard-to-reach rural areas. To use P&G packets, only simple, readily available household implements (bucket, stirring rod, filter cloth) are needed.
Water purification process
Add the contents of 1 packet to 10 liters (2.5 gallons) of water and stir to begin the precipitation and coagulation process
Stir for 5 minutes until floc forms and water is clear.
Let stand for 5 minutes
Filter the water through a clean 100% cotton cloth and discard the separated flocs in the latrine.
Wait 20 minutes before drinking to allow for complete disinfection
Store in a suitable container to avoid recontamination
Exists evidence conclusive evidence that simple, acceptable, low-cost interventions at the level of home and community are capable of dramatically improving quality microbial of water stored in the home and reduce the concomitant risks of disease diarrhea and death.
The combined systems of flocculation/disinfection have been classified by the WHO as a "protective" technology, they are effective in reducing pathogens of all kinds, have demonstrated health benefits, leave protection waste and eliminate muddy sediments.
