What is an injector?

• A. A heating device for chlorine
• B. A venturi device that pulls chlorine gas into a stream of dilution water
• C. A container for storing chlorine
• D. A type of backwashing filter

Answer: (B)

An injector is a critical component in water treatment processes, specifically in the context of introducing chemicals like chlorine into the water stream. It operates based on the principle of creating a vacuum or negative pressure, often utilizing a venturi effect. When water flows through the venturi injector, it constricts at a certain point, causing a drop in pressure that pulls chlorine gas into the stream of dilution water. This process ensures that chlorine is mixed thoroughly and uniformly with the water, allowing for effective disinfection and treatment. The precise injection of chlorine is essential for controlling water quality, making the injector integral to the disinfection process. Understanding the role of an injector helps underscore the importance of accurately dosing chemicals in water treatment systems to maintain safety and efficiency.
