Rotasieve Technology: A Closer Look

The Rotasieve, a type of externally fed rotary fine screen, stands out as a highly effective solution for solid-liquid separation in various applications. It utilizes a rotating drum with a fine mesh screen to capture and remove suspended solids from liquids. The system's simple yet effective principle makes it a versatile choice for treating wastewater, industrial process water, and even potable water supplies.

Key Techniques Employed by the Rotasieve:

• Rotary Screening: The heart of the Rotasieve is its rotating drum equipped with a fine mesh screen. This screen acts as a barrier, capturing solid particles while allowing the liquid to pass through.
• Flow Direction Control: The Rotasieve design ensures consistent flow direction across the screen. This eliminates the possibility of clogging and maintains optimal performance.
• Solid Discharge System: The captured solids are transported to the top of the drum through the screen's rotation. They are then discharged into a separate collection container, preventing contamination of the clean water.
• Efficient Cleaning Mechanism: The Rotasieve can be equipped with self-cleaning mechanisms to prevent buildup on the screen. These mechanisms include brushes, jets, or even air blasts, ensuring uninterrupted operation.

Advantages of Rotasieve Technique:

• High Efficiency: The Rotasieve can remove a significant percentage of suspended solids, even particles as small as 10 microns.
• Low Head Loss: The system's design minimizes pressure drop, reducing energy consumption and operational costs.
• Versatile Applications: The Rotasieve can handle high flow rates and different types of liquids, making it suitable for various industrial and municipal applications.
• Durable Construction: The Rotasieve is built with high-quality materials that ensure long-term performance and minimal maintenance requirements.
