NOVELTY - The solid granular support is made up of pozzolana, limestone, sand, stone sandpapers, basalt, clay, quartz, anthracite, activated alumina or zeolite. The micro fungus is continuously cultivated in a separate bioreactor. The contact time of the liquid with the fluidized/jigged bed of fungal biomass is 2-4 days. The metals are adsorbed by the passage on the bed of biomass. The bed is washed by putting into circulation in the reactor of water in hydraulic conditions allowing to desorb metals.    USE - The methos is useful for the decontamination of muds or effluents loaded with metals.    ADVANTAGE - Compact, very simple and cost effective process. Washing of the fluids and the metal adsorption/desorption are effectively carried out. The biological degradation of the organic martial and the effective retention of metals coming from the fluids are improved.    DETAILED DESCRIPTION - The micro funguses of the fungal biomass are Penicillium roqueforti, Penicillium chrysogenum, Penicillium atramentosum, Trichoderma viride, Trichoderma reesei, Trichoderma harzianum, Mucor hiemalis, Mucor racemosus, Mucor fuscus, Mucor plumbeus, Galactomyces geotricum, Aspergillus phoenicis, Aspergillus niger, Geotricum candidum, Phoma glomerata, Botrytis cinerea and Geomyces pannorum. The metals are chromium, cadmium, nickel, copper, zinc, lead, mercury, aluminum, arsenic, selenium, cobalt and their mixtures. The hydraulic conditions permit to desorb metals obtained with the water flow velocity of 20-25 times higher than the passage speed of the fluid on the biomass bed during adsorption. The growth rate of the bed is 30-50% during the washing and 20% during the adsorption of metals. The growth rate of the bed during washing is higher than the expansion rate of the bed during adsorption.    An INDEPENDENT CLAIM is also included for installation of decontamination of the organic material of liquid and/or of decontamination of liquid loaded with metals.
