Rotopass: Fine-Tuning Water Treatment with Externally Fed Rotary Screens

In the realm of environmental and water treatment, efficient and reliable solid-liquid separation is paramount. This is where the Rotopass, a revolutionary externally fed rotary fine screen developed by Passavant-Roediger GmbH, takes center stage.

Understanding Rotopass:

Rotopass is an innovative filtration system designed for precise and efficient removal of suspended solids from various water sources. Its core technology lies in its externally fed rotary fine screen, a sophisticated mechanism that separates solids from liquids based on particle size.

Chapter 1: Techniques

Rotopass: A Deeper Dive into Its Functionality

The Rotopass system utilizes a unique combination of techniques to achieve high-efficiency solid-liquid separation:

• External Feeding: Water enters the Rotopass from the outside, flowing towards the rotating screen. This design promotes even distribution of the water stream and minimizes clogging, even with high volumes of suspended solids.
• Rotary Screen Operation: The heart of the Rotopass system is the rotating fine screen. This screen consists of a series of perforated plates or mesh, with adjustable gaps to tailor the filtration process to specific requirements. The screen continuously rotates, ensuring even filtration across its surface.
• Self-Cleaning Mechanism: A dedicated cleaning zone is integrated into the system. As the screen rotates, it encounters this zone, where high-pressure water jets or brushes effectively remove accumulated solids. This automatic cleaning function ensures consistent performance and minimizes downtime.
• Hydrodynamic Separation: The Rotopass utilizes the principle of hydrodynamic separation. Suspended solids larger than the screen gap are retained, while smaller particles pass through, leading to clear and purified water.

Benefits of Rotopass Techniques:

• High Separation Efficiency: The combination of external feeding and the rotating screen allows for optimal filtration performance, achieving high separation efficiency with minimal particle escape.
• Reduced Downtime: The self-cleaning mechanism minimizes the need for manual intervention, reducing downtime and ensuring continuous operation.
• Adjustable Filtration: The ability to adjust the screen gap allows for flexible filtration capabilities, adapting to various applications and water quality requirements.
