An engineering system capable of degrading biologically in continous operation IWWs (industrial waste water) contaminated with heavy metals using native strains of Aspergillus sp. using a new technology was implemented efficiently incorporating plug flow reactor. The system was configured with eight fully stainless steel tubes packed with immobilized cells of Aspergillus sp. circularly arranged within a cylindrical tank way to provide heating jacket thermostating system possessing bioscrubber fungal strains to develop its maximum performance at 30 ± 1°C, likewise, was also an electric 2 HP nominal power centrifuge which was fed wastewater and recirculated through the system to get their purging heavy metals (Cu, Zn, Cd and Pb) so that when the system worked was allowed into the raw water to the tubes containing immobilized fungal cells and with which contact is executed removal and cle...
