Researchers at University of North Carolina (UNC) are developing a "rapid sand" filter that can provide fresh, clean, and safe drinking water to millions in developing countries. Dr. James Amburgey, ...

Mineral coatings on sand particles actually encourage microbial activity in the rapid sand filters that are used to treat groundwater for drinking, according to a paper. These findings resoundingly ...

The studied waterworks follows a treatment chain consisting of aeration and two sequential filtration steps. The aerated water flows downward through a first RSF, designed to remove ferrous iron, and ...

Sand filters are commonly applied in drinking water treatment and can efficiently remove suspended solids, organic matter, and microorganisms from source water. During the process, particulate matter ...

As an efficient, inexpensive, low-tech way to treat water, new research could bring clean, safe drinking water to potentially millions upon millions of people. As an efficient, inexpensive, low-tech ...
