Which type of chlorine gas feeder is most commonly used?

The most commonly used type of chlorine gas feeder is the vacuum feeder. This system operates by creating a vacuum that draws chlorine gas from the supply tank into the feeder. This method is favored because it minimizes the risk of gas leakages and enhances safety by ensuring that chlorine does not escape into the atmosphere. The vacuum system also allows for precise control of the gas flow, which is critical for maintaining the correct dosage of chlorine in water treatment processes.

In addition, vacuum feeders are typically easier to operate and maintain compared to other types of feeders, making them a practical choice for water treatment facilities. They effectively prevent the backflow of water into the gas line, further ensuring that chlorine is delivered to the treatment process safely and efficiently. This reliability and effectiveness in managing chlorine gas applications is what makes vacuum feeders the standard in the industry.
