Abstract

Filtration process using fibrous filter media is very used to retain microparticles in a stream air due to simple use, low operational cost and high collection efficiency. However, the study of submicron particles is still incipient in Brazil and also internationally. New technologies producing filter media are coming to light to achieve high particles collection efficiencies with low pressure drop as filters with nanofibers. Application of nanofibers in air filtration is a relativity new technology and not implemented yet by the national filter media manufactures. In general, existing filter media in Brazilian market are imported and expensive. Electrospinning method is very used among several techniques to produce nanofibers because it's simple and versatile. This method use electrostatic force to obtain fibers with high contact surface compared with those produced by other methods. One of the difficulties to produce these filter media is the adjustment and control of several parameters which influence on production of the nanofiber as polymer concentration, rate of solvent, nanofibers deposition time on the substrate, distance from the collector and the electric tension. The full knowledge producing filter media containing nanofibers make possible their optimization in order to obtain high retention efficiencies in the range of nanometric particles, associated with low pressure drop. However, the aim of this project is develop a production technology of nanofibers filter media to remove nanoparticles of environmental using electrospinning technique. After the production of fibrous filter media they will be physically characterized and then will be obtained the collection efficiencies of nanometric particles in order to evaluate how nanofibers properties affect the collection efficiency of nanoparticles.
