RADICIFIBRAS: WATER TREATMENT WITHOUT CHEMICALS In 2010 Radicifibras, a Brazilian company engaged in the production of nylon and acrylic fibre, chose the Second Earth Inc. WRAP (Water Reclamation & Asset Protection) system for its biggest cooling tower. WRAP is a physical water treatment system that uses Faraday magnetic amplifying assemblies installed at various points along the production line. A WRAP system provides many benefits: it eliminates scale build-up and reduces corrosion, thus improving process water quality. Furthermore, a WRAP system does not use chemicals for water treatment. In the case in point, the Radicifibras cooling tower, 16.5 tons of chemicals per year are eliminated.
