A practical experience for a primary school class in Bologna (Italy)
With the purpose of raising awareness about water quality, students have played with water making it dirty with colorants, shampoo, oil, detergents, hygene products, sunscreen, cosmetics, mud, soil, leaves.
Then, they constructed a multilayer filter made of LIFE REMEMBRANCE polysulfone recycled granules, sand, granular active carbons.
To try the efficiency of the handmade filters, dirty water was poured into them and water turned clean!
Thanks to CNR-ISOF, Medica SpA, HERA SpA – Water Utility, Maestra Raffaella and the VC for allowing this great opportunity!
