Abstract:
1. A method for treating water from water systems that include anti-biofouling quaternary amine compounds, the method comprising the steps of: providing water contaminated with anti-biofouling quaternary amine compounds; providing bentonite clay in particulate form at a determined rate, wherein said determined rate being adjustable; providing mix water at a determined rate, wherein said determined rate being adjustable; combining said mix water with said particulate bentonite clay in a mix tank on-site with said water contaminated anti-biofouling quaternary amine compounds to produce a bentonite clay slurry at a determined concentration; and directly transferring said clay slurry by pipe flow through a fluid communication line from said mix tank and into said contaminated water contaminated with anti-biofouling quaternary amine compounds to reduce the amount of said quaternary amine compounds in said water; wherein the amount and the concentration of said clay slurry are at least sufficient to detoxify the amount of said quaternary amine compounds in said water, wherein the rates of said bentonite clay and said mix water are adjustable to ensure that the amount and the concentration of said clay slurry are at least sufficient to detoxify the amount of quaternary amine compounds in said water, wherein the combining step comprises adjusting the determined rate of said particulate bentonite clay delivered to said mix tank to produce the determined concentration of said clay slurry, and wherein the combining step comprises adjusting the determined rate of said mix water to said mix tank to produce the determined concentration of said clay slurry.
