N2 - Since ancient times, colloidal silver has been used primarily for water disinfection, as medicinal products, among others; however, its efficiency is a function of the size of the metal particle with which the interaction occurs. In the case of this research, clay filters were designed and developed with aggregate of micrometric-sized silver particles (commercial colloidal silver) and silver nanoparticles (NP Ag), the latter synthesized by the green chemistry method (biosynthesis) from of reducer obtained from residues of wine production. As a case study, the sample of water from the Moche River affluent, located in the Province of Trujillo, La Libertad - Peru, which has a high content of microbiological contamination has been considered. For the evaluation of silver colloids, results are presented by spectrophotometry, both with concentrations of 12 ppm, which proves that the green chemistry method is efficient for obtaining NP Ag and approximately 30 nm in size. Fourier transform infrared spectroscopy (FTIR) results are shown which approximate the phytochemical reduction mechanism; The results suggest the potential antibacterial effect of filters with NP Ag for viable mesophilic heterotrophs (97.43%), total coliforms (90%), fecal coliforms (76.08%) and E. Coli (90%).
