Internal Fed Rotary Drum Screen for Wash Bay

In wash bay facilities, the Internal Fed Rotary Drum Screen is essential for efficiently separating solids from liquids, ensuring effective wastewater treatment. This essay explores the mechanics, benefits, applications, and maintenance of this crucial equipment.


The Internal Fed Rotary Drum Screen operates by allowing wastewater to flow through a feed box into the rotating drum. A fine mesh screen captures solids while letting liquids pass through. Internal flights transport solids along the drum, discharging them at the end. The continuous rotation and internal spray system keep the screen clean and prevent clogging.


  1. Efficiency: Capable of processing large volumes of water continuously.
  2. Versatility: Suitable for various applications, including wash bays and municipal wastewater treatment.
  3. Compact Design: Fits easily into facilities with limited space.
  4. Low Maintenance: The self-cleaning mechanism reduces the need for frequent manual cleaning.
  5. Durability: Made from robust materials like stainless steel, ensuring longevity.


In wash bays, such as car washes and industrial cleaning stations, the Internal Fed Rotary Drum Screen removes solids like dirt and grease from wastewater. This prevents blockages and protects downstream equipment. For example, in car washes, it captures sand and grit, while in industrial settings, it handles slurry and sediment-laden water.


Regular maintenance ensures optimal performance:

  1. Routine Inspections: Check for wear or damage.
  2. Cleaning: Periodically remove stubborn residues.
  3. Lubrication: Lubricate bearings and drive components as recommended.
  4. Replacement of Worn Parts: Keep spare parts on hand to minimize downtime.


The Internal Fed Rotary Drum Screen is vital for wastewater treatment in wash bays, offering high efficiency, versatility, and low maintenance. By effectively removing solids, it protects downstream systems and contributes to environmental sustainability. As wastewater management evolves, this technology remains essential for ensuring clean discharge and operational efficiency.
