ABSTRACT:
A method for bioremediation of grease traps, which includes the steps of mechanically removing solid materials such as plastic items, food particles and the like from entrances to all drain lines and the drain lines themselves terminating in the grease traps; securing loose drain line covers and replacing broken covers; preventing the flow of all chemicals which are detrimental to the growth of endemic bacterial microorganisms into the drain lines and grease traps; adjusting the pH of the water effluent in the grease traps by introducing a basic material such as baking soda into the grease traps and mixing or stirring the water, which stimulates the endemic native bacteria resident in the grease trap; and adding endemic bacterial microorganisms to one or more of the drain lines for ultimate introduction into the grease traps and biodigesting grease in the drain lines and grease traps.
