How a Bypass Feeder Works
A bypass feeder is installed on a side-stream loop connected to a closed-loop water system. Treatment chemicals are placed inside the feeder vessel, and system water circulates through the unit, gradually dissolving and distributing the chemicals throughout the system.
This controlled treatment process helps maintain proper water chemistry while reducing corrosion, scaling, and other issues that can negatively impact equipment performance and system efficiency.
