A well-designed feed system is crucial for an effective water treatment program. Inadequate feed systems can lead to high chemical costs, increased corrosion, equipment maintenance, and erratic product quality. Problems include excessive chemical use, rapid equipment wear, potential damage from chemical spills, and higher operational costs due to poor control and additional labor.

Investing in a properly designed chemical feed system can prevent these issues and is often justified by the high costs associated with poor chemical control. Feed systems vary by components, control schemes, applications, and types of materials fed (liquid or powder).

Feed System Components:

Chemical Storage:

• • Bulk Storage: Suitable for high usage rates. Chemicals are delivered in large quantities and managed by service agents, with a large tank on-site and optional smaller day tanks for controlled feed.

  • Semibulk Storage: Used for moderate chemical feed rates with reusable shuttle tanks, which are easy to stack and fill.

  • Drum Storage: Historically common, but now less used due to environmental regulations and disposal challenges.

Choosing the right storage method depends on usage rate, safety, space, inventory needs, and regulations.
