Описание: The Christopher Robert Project's uniquely designed bio-sand water filter will produce 60-80 liters everyday. The bio-sand filter has been studied in the field and in labs. It has been proven to remove the following from contaminated water: Up to 100% of helminthes, Up to 100% of protozoa, Up to 98.5% of bacteria and 70-99% of viruses. Our filter also removes arsenic and guinea worm. Here it is being primed with a known contaminated water source and as you can see, green water goes in and clear water runs out after only one week. It will take 3-4 weeks for the thin bio-layer to build up making this water totally safe to drink.
