Performic acid on-site generator and formulator

A method of on-site generating performic acid forming composition comprising:

• providing a formic acid source to a length of pipe at a desired flow rate;
• providing an oxidizing agent to said length of pipe at a desired flow rate;
• contacting said formic acid source with an effective amount of said oxidizing agent within said length of pipe in the presence of a heating device to form a performic acid composition;
• delivering said performic acid composition to a downstream cooling system, wherein said performic acid is an individual or mixed performic acid composition according to a user- or system-inputted selection,
• wherein the reaction to form the performic acid composition begins generating yield instantaneously and reaches maximum yield within 10 minutes or less.

A method of cleaning using an on-site generated performic acid composition comprising:

• obtaining a user-or system-inputted performic acid composition on-site using the adjustable biocide generator system comprising:
• an apparatus comprising at least one inlet, a length of pipe, a heating device, and an outlet for dosing a performic acid forming composition from said length of pipe;
• wherein said inlet(s) are in fluid connection with said length of pipe and supply reagents to produce said performic acid forming composition in said length of pipe;
• wherein said reagents comprise a formic acid source and an oxidizing agent;
• and
• wherein said length of pipe is in fluid connection with said outlet to dispense said performic acid forming composition to a cooling system;
• applying said performic acid composition in an amount sufficient to sanitize, bleach and/or disinfect a surface in need thereof.
