Composition, System, and Method for Treating Water Systems

A method of removing biofilm and treating a fluid system containing a membrane, the method comprising the steps of:

• adding a surfactant, a first chelating agent, and a second chelating agent or other ingredient that will react with the first chelating agent to produce a second chelating agent to the fluid system in amounts sufficient to provide concentrations of at least 0.00015 M for the surfactant, at least 0.001 M for the first chelating agent, and at least 0.0005 M for the second chelating when mixed with a volume of fluid in the fluid system containing the membrane or portion thereof being treated;
• circulating the fluid containing the surfactant and chelating agents through at least a portion of the fluid system to contact the membrane;
• and
• wherein the fluid system is a nanofiltration, ultrafiltration, microfiltration, forward osmosis, reverse osmosis, or conventional particle filtration system.
