The Aqua Guard® Screen series from Parkson Corporation offers advanced screening solutions for wastewater treatment applications. Each screen type – Aqua Guard, Aqua Guard Ultraclean, and Aqua Guard-PF – features three-dimensional screening technology, self-cleaning functionality, durable construction, energy efficiency, and versatility. These features ensure optimal performance, reduced maintenance, and long-term reliability, making Aqua Guard® Screens the ideal choice for most water and wastewater treatment plants.
Principle of Operation
Key Steps:
Influent Water Entry
The process begins when influent water containing solids and debris enters the Aqua Guard® Screen through an inlet channel. This water is directed towards the screening area where the filtration process is initiated.
Three-Dimensional Screening Mechanism
Key Components:
- Screening Panels: The Aqua Guard® Screen features patented three-dimensional screening panels. These panels are essential for enhancing the capture efficiency of small particles and fine debris.
- Rotating Drum: The screening panels are mounted on a rotating drum that allows them to move continuously during operation.
Operation:
- As the influent water passes through the three-dimensional screening panels, the unique structure captures and retains a higher percentage of fine solids compared to traditional two-dimensional screens.
- The 3D design ensures uniform flow distribution across the entire screen surface, preventing localized clogging and maintaining consistent filtration performance even with varying flow rates.
Debris Conveyance and Removal
Key Components:
- Conveyor System: Captured debris is conveyed upwards by the rotating drum.
- Discharge Zone: At the top of the conveyor system, the debris is directed towards the discharge zone.
Operation:
- As the screening panels rotate, the captured solids and debris are lifted out of the water and conveyed towards the discharge zone.
- The debris is then discharged into a collection bin or conveyed to a disposal system, ensuring efficient removal from the water stream.
Self-Cleaning Mechanism
Key Components:
- Brush System: The Aqua Guard® Screen is equipped with strategically positioned brushes to clean the screening panels.
- Spray Nozzles: High-pressure spray nozzles provide additional cleaning force.
Operation:
- As the screening panels rotate and convey debris, the brush system continuously scrubs the panels, removing adhered particles and preventing clogging.
- High-pressure spray nozzles enhance the cleaning process by washing away fine particles, ensuring the screening surface remains clear and functional.
Effluent Water Exit
After passing through the screening panels, the filtered water exits the AquaGuard® Screen through an outlet channel. The water, now free from solids and debris, can be directed to downstream treatment processes or discharged as per the facility’s requirements.
Aqua Guard® PF Screen
- Perforated Plate Technology: The Aqua Guard® PF features perforated plate screening technology. Have precisely sized and spaced perforations that provide a higher open area compared to mesh screens, allowing for more efficient filtration and higher flow rates. Designed for higher capture rates, making the PF model suitable for high-volume applications where robust screening is required.
- Efficient Self-Cleaning System: The cleaning system, featuring both brushes and high-pressure spray nozzles, is designed to maintain the perforated plates’ integrity by removing debris. This ensures clear plates, consistent performance, and reduces the need for frequent manual cleaning.
Aqua Guard® UltraClean Screen
- High-Efficiency Ultrafine Screening Panels: The Aqua Guard® UltraClean is designed with advanced ultrafine screening panels that provide exceptional contaminant removal. These panels are engineered to capture the smallest particles and fine debris, making it ideal for applications requiring high-efficiency filtration.
- Advanced Self-Cleaning System: The UltraClean model incorporates a sophisticated self-cleaning mechanism with enhanced brushes and high-pressure nozzles. The brushes are designed to handle fine particles more effectively, and the nozzles provide powerful cleaning action to keep the panels free from clogging.
