Water Filtration Sand Filter
Researchers at Purdue University have developed a new design for a slow sand filter that utilizes a plastic porous plate enclosed in a plastic woven mesh bag and is housed in the bottom of the filter. This design modification increases the usability of the filter significantly, eliminating the need for gravel and coarse sand layers. Sand that is used in the top part of the filter is the only necessary media for the operation of this filter; the larger sand capacity increases the volume of water that can be treated. The simple design allows the filter to be installed at any point-of-use location by anyone given it only requires the addition of sand; it is easy to transport. The filter is easily cleaned by removing and rinsing the sand.
Only uses sand Easy installation and cleaning Increases amount of treated water Inexpensive Easy to transport to remote locations
