Abstract:
A method for continuous bioremediation of a hydrocarbon-contaminated object comprising the steps of:placing said hydrocarbon-contaminated object in a washer basin and continuously cleaning said object by introducing and recycling through said basin in contact with said object a cleaning solution comprising microorganisms of a genus selected from the group consisting of Achromobacter, Actinobacter, Alcaligenes, Arthrobacter, Bacillus Nocardia, Flavobacterium, Peudomonas and mixtures thereof;said microorganisms exponentially increasing and degrading hydrocarbons into water and carbon dioxide;draining microbe cleaning solution containing hydrocarbons from said washer basin through a screen that removes large grit particles into a biochamber reservoir;aerating said microbe cleaning solution in said reservoir to provide oxygen for the microorganisms;heating said microbe cleaning solution in said reservoir to a temperature of between about 90.degree. to 112.degree. to maximize microbial growth in said microbe cleaning solution;continuously removing heavy sediment from said microbe cleaning solution into a sediment trap;continuously screening said microbe cleaning solution through a plurality of filters to remove sediment of less than 10 microns to prevent sludge from forming in said reservoir; andrecycling said microbe cleaning solution having sediment less than 10 microns removed to said reservoir or to said washer basin and then to said reservoir.
