PAUL, the ‘WaterBackpack’, is a small and portable (23 kg) membrane filtration unit which removes bacteria, virus and other pathogens by 99.99% (avg., up to 99.99999%) from contaminated water without chemicals or electric energy, and can be operated even by illiterates in emergencies. 4,200+ PAUL units exist in 91 countries worldwide.
As PAUL has a 10+ year lifetime, the so-called PAUL station arrangement – with a standard PAUL unit as the core – provides a permanent water supply for communities, schools, hospitals, offering the chance for the local population to decrease their cost for water and in addition earn their own money.
So far, more than 500 PAUL station arrangements have been installed worldwide.
