What type of feeder is used for brominators in pools?

The correct choice is erosion feeders. This type of feeder is specifically designed for the delivery of bromine into pool water. Erosion feeders work by dissolving a solid bromine compound, typically a tablet or pellet, as water flows through the feeder. The water erodes the surface of the bromine granules, releasing bromine into the pool system.

Erosion feeders are particularly effective and efficient because they allow a controlled and continuous disbursement of bromine, ensuring that the pool maintains proper sanitation levels. The consistent flow of water through the feeder optimizes the dissolution process, which is essential for maintaining the effectiveness of the bromine as a disinfectant.

Other types of feeders, such as vacuum feeders, pressure feeders, and gravity feeders, have different operational mechanisms and are typically used for different types of chemicals or applications in pool sanitation. However, for brominators specifically, erosion feeders are the optimal choice due to their design and operational efficacy.
