Techniques

Chapter 1: Techniques

Sta-Sieve: A Technological Advance in Static Fine Screening

The Sta-Sieve, a static fine screen, stands as a testament to the innovative nature of water treatment technology. This self-cleaning screen, typically featuring a stationary sieve panel with a mesh size as small as 20 microns, distinguishes itself through its unique operational techniques.

1.1. Static Screening and Backwash Mechanism:

The Sta-Sieve operates on the principle of static screening, where a stationary sieve panel captures debris from the flowing water. The screen's self-cleaning mechanism, a crucial element of its efficiency, utilizes a backwash system. This system directs a flow of clean water in reverse direction, removing accumulated debris from the sieve panel.

1.2. Types of Backwash Systems:

• Continuous Backwash: A constant flow of backwash water ensures continuous cleaning, minimizing the accumulation of debris on the screen.
• Intermittent Backwash: The backwash system cycles on and off, effectively cleaning the screen at specific intervals. This method is suitable for applications with lower debris loads.

1.3. Customized Configurations:

The Sta-Sieve's design allows for customization to meet specific project requirements. Options include varying mesh sizes, flow rates, and materials. This flexibility enables the screen to effectively handle a diverse range of debris sizes and water conditions.
