Our team of engineers has developed a variety of science-based solutions to contaminated water that are appropriate to a wide range of local contexts and needs.  Our first patented product is the Aqua Clara Bio-Sand Filter (BSF), which produces safe, affordable drinking water for thousands of families worldwide. ACI now offers a wide range of patent-pending solutions to address other water issues, whether they are found in surface water or well water, or are the result of special contaminants, such as arsenic and other heavy metals.  These technologies employ hollow membrane filtration and other media that are scalable and sustainable and do not require electricity or chemicals. They are also scalable, from units designed for households to those for schools, clinics, and other large institutions.
