A side stream filtration system's flow rate generally ranges from 3 to 10% (but can be up to 20%) of the total recirculated cooling water flow rate. A side stream filtration percentage of 3% or less of the total circulation flow rate has been shown to damage cooling systems, causing fouling throughout the cooling loop.
