Necessity Is the Mother of Invention and A Puerto Rican Scientist

While at Ames, Eduardo Nicolau developed a system named the Forward Osmosis Interfaced BioElectrochemical system (FOBE), which uses a two-step process. First, the urine is purified using forward osmosis, then drained into a bioreactor that contains activated carbon and the enzyme urease. Urease degrades urea into two molecules of ammonia.
