Hi, MDG;
This is very much dependent on the type of PAA you employ for sanitation and it's concentration. I would consult with your provider for specifics if you do not have access to spec sheets or SDS. Here is an attachment from EnviroTech which list multiple dwell times based on log reduction of pathogens, ppm, and water temp/quality.
