Techniques

Dynasieve: A Powerful Tool for Environmental & Water Treatment

Chapter 1: Techniques

1.1 Dynasieve: The Self-Cleaning Rotary Fine Screen

Dynasieve technology utilizes a rotating, perforated drum or cylinder to filter suspended solids from liquids. This process relies on the principle of mechanical filtration, where the screen surface acts as a barrier, capturing particles larger than the screen openings. Unlike traditional screens, Dynasieve systems boast a self-cleaning mechanism that ensures continuous operation and prevents clogging.

1.2 The Self-Cleaning Mechanism

The self-cleaning mechanism in Dynasieve systems is key to their effectiveness. As the screen rotates, a built-in cleaning system removes the accumulated solids from the screen surface. This cleaning system can employ different methods, including:

• Backwashing: Water is directed against the screen in reverse direction, washing away the collected solids.
• Scraping: A scraper blade moves along the screen, removing the solids.
• Vibrating: The screen is vibrated, dislodging the solids and allowing them to fall through the screen.

1.3 Fine Filtration Capabilities

Dynasieve screens are capable of achieving very fine filtration levels, ranging from a few micrometers to several millimeters, depending on the application. This fine filtration capability makes Dynasieve ideal for removing a wide range of contaminants, including:

• Suspended solids: Sand, silt, grit, and other debris.
• Microorganisms: Bacteria, algae, and protozoa.
• Organic matter: Leaves, twigs, and other organic materials.
• Solid waste: Plastics, fibers, and other solid waste.

1.4 High Flow Rates

Dynasieve screens are designed to handle large volumes of liquid, thanks to their continuous operation and efficient cleaning mechanism. This ensures optimal performance, minimizing downtime and allowing for efficient processing of water and wastewater.
