How a Dome Bottom Bypass Feeder Works
A bypass feeder is installed on a bypass piping loop connected to a circulating water system. Water flows through the feeder vessel, allowing treatment chemicals to dissolve and gradually enter the system. This process helps maintain proper water chemistry while protecting equipment from corrosion, scale formation, and biological contamination.
The larger vessel capacity of the DB-12HD makes it especially useful for facilities with substantial system volume and ongoing water treatment requirements.
