In a slurry feed system, where should the feeder be located to avoid danger of settling?

• A. At the end of the feed line
• B. At exactly the feed point
• C. Above the main treatment tank
• D. At the beginning of the feed line

Answer: (B)

In a slurry feed system, positioning the feeder at the exact feed point is crucial for preventing the settling of solids. When the feeder is located here, it ensures continuous movement of the slurry through the system, which helps keep solids suspended. This placement minimizes the risk of any material settling out of the slurry as it moves toward the treatment process.

If settling occurs, it can lead to blockages, reduced system efficiency, and inconsistent slurry composition, all of which negatively impact the treatment process. Maintaining a dynamic flow at the feed point helps ensure that the treatment tank receives a uniform mixture, which is essential for effective processing and operation.

The other options may create conditions where settling can occur. For instance, placing the feeder at the end of the feed line can allow settling to happen upstream, while positioning it above the main treatment tank may result in gravitational forces causing solids to settle before they reach the tank. Starting at the beginning of the feed line can ensure that material is flowing; however, it doesn't directly address the concern of settling as effectively as being at the exact feed point can.
