Product Description

LifeStraw Community is a high volume capacity point of use water filtration unit designed for emergency and humanitarian aid settings. The filter is effective for removing almost all viruses, bacteria, parasites, and microplastics from water.  The total capacity of the community filter is 50 liters, where 25 liters are used as a source water tank and the other 25 are used for the safe water storage tank. The lifetime of this filter is approximately 26,000 gallons (100,000 liters), enough to serve 100 people for 3 to 5 years. It is manufactured by Vestergaard Frandsen and is commercially available for purchase.

Design Specifications

Design specification of LifeStraw Community includes: Filtration technology: 0.02 micron membrane ultrafilter cartridge Purifier lifetime: 25,000 gallons (100,000 liters) Flow Rate:12 liters/hour Food grade materials (US FDA 21 CFR standards) Total capacity: 50 liters (13 gallons) Weight: 17lbs (8kgs) (without water) Size (assembled): 22.’’ x 22.’’ x 33.5 ‘’ Size (box): 22.4’’ x 22.4’’ x 24.4‘’ Replaceable purification cartridge All parts are recyclable The operational procedure of LifeStraw Filter: 25 liters of untreated water is poured into the top of the unit, also called the dirty water container The pre-filter removes coarse particles larger than 0.080 mm The hollow-fiber ultrafiltration membrane cartridge then stops all suspended particles and pathogens larger than 20 nanometres (including all bacteria, viruses, and protozoan cysts). Particles and microbes larger than 20 nanometres stay on the dirty side of the membrane and clean/purified water passes through the membrane Purified water can be collected from any of the four taps The backwashing handle allows semiautomatic backwashing; when it is pulled down and released, pathogens and dust particles on the dirty side of the membrane are lifted by backpressure and then flushed out into the red backwash container.
