Chemical Injection

Chemical injection systems are sometimes necessary to treat water chemistry, pathogens, and water contamination.

🛈 How it works:

➤ A pre-engineered chemical mixture is stored in a chemical tank

➤ A metering pump controls the chemical injection rate

➤ The chemical mixture is pumped from the chemical tank and injected into the water

➤ The chemical mixture mixes in the water stream to treat the water

We typically avoid injecting chemicals into the water if there is a suitable alternative, but there are instances where chemical injection is the best or only option.

There are a wide variety of chemicals used in drinking water treatment, from residential applications all the way to the municipal level. Chlorine is the most common chemical used for oxidation and sanitization of biologics in the water, but many others are used for everything from pH adjustment (soda ash), to corrosion control (polyphosphate).

Also, we frequently use chemical injection to sequester iron in irrigation water to prevent iron staining on plants.
