JXN-600 Internally Fed Rotary Drum Screen

An Internally Fed Rotary Drum Screen is a type of mechanical screening device used primarily in wastewater treatment plants to remove solids from liquids. This device is particularly effective in applications where solids need to be separated from wastewater or process water. 

Structure and Components
1. Rotary Drum: The main component is a cylindrical drum that rotates. The drum is perforated with fine screens or mesh that allows water to pass through while capturing solids on its surface.
2. Feed System: Wastewater or process water is fed into the drum from the inside. This is why it is called "internally fed."
3. Drive System: A motor and gearbox system rotate the drum at a controlled speed.
4. Spray Bar: High-pressure water jets are often used to clean the drum's exterior, ensuring continuous operation and preventing clogging.

How It Works
1. Influent Introduction: The influent (wastewater or process water) is introduced into the center of the rotating drum.
2. Screening Process: As the drum rotates, the water passes through the perforations or mesh on the drum's surface. Solids larger than the openings are retained on the inside of the drum.
3. Solids Removal: The retained solids are carried by the rotating drum to a discharge point where they are collected or conveyed away.
4. Effluent Discharge**: The filtered water, now free of larger solids, passes through the screen and exits the drum.

In summary, an Internally Fed Rotary Drum Screen is a robust and efficient solution for separating solids from liquids in various wastewater and process water applications, offering reliable performance with low maintenance needs.
