The Fundamentals Of Municipal Chemical Injection Begin With Safety

By SAF-T-FLO Chemical Injection

Safety is the most important issue to consider when choosing or working with chemical injection quills. The goal of chemical injection is to inject a chemical solution into a water main through a device called an injection quill. Moving water, pressure within the water main, and the chemical solution are important factors to consider when choosing a chemical injection quill. They also have the greatest impact on operator safety.

Chemical solutions are commonly used in water & wastewater treatment. The chemical solution is injected into the center of the water main where velocities are highest and the injection point is farthest away from the pipe sidewall. Some chemical solutions used in municipal water treatment are corrosive piping and equipment. Care must be used when selecting an injection quill for use with corrosive chemical solutions.
