Contaminated Water from Open Surface Water Sources: Sand and Hollow Membrane Filters (SAM I)

ACI filters have been designed for use in circumstances where larger volumes of water are needed, such as hospitals, clinics, orphanages, and schools and the water sources yield contaminated, turbid water.

The filtering process is characterized by an initial cleaning of all incoming waters by a fine sand filtration device (a “trickle sand filter”) which reduces turbidity and prepares the water for its final cleaning. The final cleaning steps use hollow fiber units (similar to kidney dialysis technologies) to remove bacteria from the water and, in the case of hospitals, a final, micro hollow fiber unit that removes viruses as well. The first generation high volume hollow fiber units combine slow sand filtration and hollow fiber units and are designed for facilities that have large water volume needs. Depending on configuration, output will vary from 1,000 to over 10,000 liters per day of clean water.
