How to Make a Water Filter as a Science Experiment Sciencing Slow sand filters now are also being tested for pathogen control of nutrient solutions in hydroponic systems. A water filter science experiment makes a fun and educational rainy-day activity for kids. This filter, made mostly from inexpensive household items, will teach kids about the processes water purification plants use.
Electrodialysis for water desalination A The first documented use of sand filters to purify the water supply dates to 1804, when the owner of a bleachery in Paisley, Scotland, John Gibb, installed an experimental filter, selling his unwanted surplus to the public. The need for unconventional sources of fresh water is pushing a fast development of desalination technologies, which proved to be able to face and solve the problem.
