Techniques

Super Sieve Screens: A Powerful Tool for Environmental & Water Treatment

Chapter 1: Techniques

This chapter delves into the technical aspects of Super Sieve Screens, exploring how they function and the different techniques employed in their design and operation.

1.1 Filtration Mechanisms:

• Surface Filtration: Solids are retained on the surface of the screen mesh, allowing the liquid to pass through. This method is commonly used for removing larger particles.
• Depth Filtration: Solids are captured within the mesh structure, often relying on a combination of physical sieving and pore blocking. This technique is effective for smaller particles and can achieve finer filtration.

1.2 Screen Designs:

• Panel Screens: These consist of multiple panels with perforated openings, providing a large filtration area. They are commonly used for high-flow applications.
• Rotary Screens: A rotating drum with a screen surface filters the liquid. The collected solids are continuously removed from the drum. This design is well-suited for handling large volumes of debris and for self-cleaning operations.
• Vibrating Screens: These screens use vibrations to enhance solids discharge and prevent clogging. They offer high efficiency and are suitable for handling materials with a wide range of particle sizes.

1.3 Mesh Selection:

• Mesh Size: The openings in the screen mesh determine the size of solids that will be removed.
• Mesh Material: The choice of mesh material depends on the nature of the liquid, the solids being filtered, and the operating environment. Common materials include stainless steel, plastic, and wire cloth.

1.4 Flow Control & Optimization:

• Flow Rate: The volume of liquid passing through the screen per unit time. This parameter directly influences filtration efficiency.
• Pressure Drop: The difference in pressure between the inlet and outlet of the screen. Optimizing flow rates and screen design minimizes pressure drop, enhancing energy efficiency.

1.5 Maintenance & Cleaning:

• Backwashing: A process that reverses the flow direction to remove accumulated solids from the screen surface.
• Screen Cleaning: Periodic cleaning is required to maintain optimal performance and prevent clogging.

Chapter 2: Models

This chapter presents various Super Sieve Screen models and their specific applications.

2.1 Standard Super Sieve Screens:

• Horizontal Screens: These are commonly used for pre-treatment applications, such as removing large debris from raw water.
