Controlling the development of biofilms in industrial process waters.

摘要

A method for inhibiting the development of an adjacent one surface biofilm, the method being characterized by: intermittently operated one biofilm inhibiting substance to a collection of microorganisms, located at an interface between water and a surface of a solid in a environment industrial water, which has the potential of developing biofilms, including intermittent administration of said biofilm inhibiting substance to water communicating with said collection of microorganisms, wherein the biofilm inhibiting substance is applied at a feed rate and according to a feeding regime which is insufficient to cause significant destruction of said collection of microorganisms, wherein said biofilm inhibiting substance is applied to said collection of microorganisms periodically with a lower work factor 1:50, where the factor work means the rela tion between (a) the time period during which the biofilm inhibiting substance is administered to said collection of microorganisms and (b) the time period during which the biofilm inhibiting substance is not administered wherein said collection of microorganisms is attached to a consumable surface and said application intermittently comprises administering intermittently said biofilm inhibiting substance for a period of about 5 minutes at each intermittent application, wherein said intermittently applying a biofilm inhibiting substance includes intermittently generating the biofilm inhibiting substance in real time and includes supplying said biofilm inhibiting substance to said collection of microorganisms as said biofilm inhibiting substance is generated in real time, wherein said intermittent generation of said biofilm inhibiting substance to you Real empo includes producing a predetermined dilution of an oxidant hypochlorite, producing a predetermined dilution of ammonium bromide, the synchronous introduction the two dilutions into a mixer to continuously mix according to a predetermined ratio to produce the inhibitory substance biofilm having an effective amount of reproducibility, stability and efficacy in situ in the mixer, wherein said biofilm inhibiting substance includes an effective amount of chloramine bromide activated and the concentration of chloramine bromide activated is between about 1 part per million to about 10 parts per million, expressed as total chlorine.
