Bio-Sand Filter (BSF)

The first, standard Aqua Clara International bio-sand filter improves water quality through use of a bio-layer, sand filtration, and the addition of ACX, a brass alloy disinfecting compound. These filters reduce the organic matter, sediments, and parasites found in source water, providing a family with 40 liters of clean drinking water per day. Water quality meets or exceeds W.H.O. standards; the cost of the filter is approximately $0.001 per liter. ACI’s flagship product is the Aqua Clara International Bio-Sand Filter (BSF). The Purifier body is assembled from PVC pipe and HDPE plastic bodies of whatever type is locally available. Local sand and gravel can be sieved for filler material. The standard BSF is a single-family point-of-use water purification system that can produce 40 liters of safe drinking water daily. Different sized Purifiers can be constructed. The unit is simple, but the process that goes on within it is not. The BSF incorporates patent pending technology which ACI gives away free of charge to those interested in forging a sustainable solution to water issues in their communities and who participate in our required training workshops. ACI exists to empower and support those endeavors. It:
