What is the primary function of an injection pump in water treatment?

The primary function of an injection pump in water treatment is to inject chemical additives. This process is essential for various reasons, such as disinfection, pH adjustment, and the elimination of contaminants. Injection pumps precisely deliver these chemicals into the water stream to ensure that the desired treatment level is achieved, which can improve water quality and safety.

Chemical additives, such as chlorine, chloramines, or phosphates, are often necessary for controlling biological growth, corrosion, and scaling in water systems. The ability to accurately control the dosage of these chemicals is vital for effective water treatment, making the role of the injection pump crucial in maintaining safe and clean water standards.

In comparison, filtering water involves the removal of particles and impurities, which is a separate process typically accomplished with filtration systems, rather than through the injection of chemicals. Measuring flow rate relates to monitoring the volume of water being treated but does not pertain to adding chemicals. Heating water also serves a different purpose in water treatment, focused on temperature increases for specific applications, rather than the chemical treatment that an injection pump provides.
