I'm reviewing our filters/magnets program for a facility that has had filters and magnets added as knee-jerk reactions to foreign material events over the last several years. Does anyone have good general reference material for where PPP should be located in a line? I know to review customer complaints and foreign material findings to determine where PPP are needed in our specific facility but I'm also looking for some kind of industry or academic reference of effective placement of PPP. Examples would be before main pumps, at delivery of bulk goods, at finished packaging, etc.
Thank you for your help if you have a good reference to share.
