Drumshear: A Powerful Tool in Environmental & Water Treatment

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.

Key Features of the Aer-O-Flo Drumshear:

  • High Efficiency: The fine mesh screen effectively removes particles as small as 20 microns, ensuring thorough removal of suspended solids.
  • Low Maintenance: The robust design and self-cleaning mechanism minimize the need for frequent maintenance, reducing downtime and operational costs.
  • High Flow Capacity: The Drumshear is capable of handling high volumes of water, making it suitable for large-scale applications.
  • Corrosion Resistance: Constructed from durable materials like stainless steel, the Drumshear is resistant to corrosion, ensuring longevity in harsh environments.
  • Flexibility: The system can be customized to meet specific flow rates, headloss requirements, and particle removal needs.

Applications:

The Aer-O-Flo Drumshear finds widespread application in various industries, including:

  • Municipal Water Treatment: Removing debris and suspended solids before filtration, ensuring clean water for consumption.
  • Industrial Wastewater Treatment: Pre-treatment of wastewater before discharge, meeting regulatory standards and protecting downstream equipment.
  • Process Water Treatment: Removing suspended solids from process water, ensuring optimal performance of industrial processes.
  • Irrigation Systems: Filtering raw water sources, protecting irrigation systems from clogging and ensuring healthy crop growth.

Benefits of Using a Drumshear:

  • Improved Water Quality: Removal of suspended solids enhances water clarity and purity, reducing the risk of contamination.
  • Reduced Operational Costs: The self-cleaning mechanism minimizes maintenance requirements, resulting in lower operational expenses.
  • Enhanced Equipment Protection: By removing harmful debris, the Drumshear protects downstream equipment from wear and tear, extending their lifespan.
  • Compliance with Regulations: The system helps meet regulatory requirements for effluent discharge, ensuring environmental compliance.

Conclusion:

The Drumshear, particularly the Aer-O-Flo Rotating Fine Screen, plays a vital role in environmental and water treatment by efficiently removing suspended solids, improving water quality, and protecting downstream equipment. Its reliability, efficiency, and adaptability make it a valuable asset for various industries, contributing to sustainable water management and environmental protection.

Drumshear Exercise:

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.

Exercice Correction

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.
