The term "Drumshear" refers to a specific type of rotating fine screen technology, often employed in environmental and water treatment applications. It is a reliable and efficient solution for removing suspended solids from various water sources, playing a crucial role in protecting downstream equipment and ensuring water quality.
One prominent example of this technology is the Rotating Fine Screen by Aer-O-Flo Environmental, Inc. This system offers a unique combination of features that make it a valuable asset for water treatment facilities and industrial processes:
How it Works:
The Aer-O-Flo Drumshear consists of a rotating drum screen with fine mesh openings, typically ranging from 20 to 200 microns. As water flows through the screen, suspended solids are captured by the mesh, effectively removing them from the water stream. The drum rotates continuously, allowing for the accumulated solids to be scraped off by a wiper blade, efficiently discharging them from the system.

Scenario:
A municipality is planning to install a Drumshear in its water treatment plant to remove suspended solids from the raw water source. The plant processes 10 million gallons of water per day (MGD). The desired headloss through the screen should be no more than 5 feet.
Task:
Using the information provided in the text, research and recommend a suitable Aer-O-Flo Drumshear model for this application. Consider the flow rate, headloss requirements, and the need to remove particles as small as 50 microns. Justify your recommendation with specific details from the Aer-O-Flo product catalog or website.
The recommended Aer-O-Flo Drumshear model for this application would depend on specific details available in the Aer-O-Flo product catalog or website. However, based on the provided information, we can suggest some general guidelines: 1. **Flow rate:** The plant processes 10 MGD, which is a significant volume. Therefore, the selected Drumshear model should have a high flow capacity to handle this amount of water efficiently. 2. **Headloss:** The desired headloss is 5 feet, which is a relatively low value. The selected model should be designed to minimize headloss while maintaining effective particle removal. 3. **Particle size:** The requirement is to remove particles as small as 50 microns. The selected model should have a mesh size that can effectively capture particles of this size. **Recommendation:** Based on these criteria, a suitable model would be the Aer-O-Flo Drumshear with a mesh size of 50 microns or smaller and a flow capacity exceeding 10 MGD. Refer to the Aer-O-Flo product catalog or website for specific model details and technical specifications to confirm the suitability of the chosen model for the municipality's water treatment plant.
