Techniques

Pulsed Bed Gravity Sand Filtration: The Heart of Hydro-Clear

The core of Hydro-Clear technology lies in pulsed bed gravity sand filtration. This technique leverages a bed of sand to remove suspended solids from water, but with a unique twist: periodic pulsing. This pulsing action dislodges accumulated contaminants, maintaining a clean filtration surface and maximizing filter efficiency.

How Pulsing Enhances Filtration

• Dislodges Contaminants: The pulsed water flow creates a fluidized bed effect, agitating the sand bed and dislodging trapped particles.
• Ensures Continuous Filtration: By removing contaminants, the pulsing action prevents clogging and ensures continuous high-quality filtration.
• Reduces Backwash Frequency: The efficient removal of contaminants minimizes the need for frequent backwashing, reducing water consumption and operational costs.

Advantages of Pulsing:

• Improved Efficiency: Consistent and efficient filtration due to the continuous cleaning of the sand bed.
• Reduced Maintenance: The self-cleaning nature of the system minimizes manual intervention and maintenance costs.
• Extended Filter Life: The pulsing action reduces wear and tear on the filter media, prolonging its lifespan.

Key Features of Hydro-Clear Pulsing Systems

• Programmable Control: Allows for customizable pulsing cycles to optimize performance based on water quality and flow rate.
• Automatic Backwashing: Automated system ensures efficient backwashing for optimal filter performance.
• Durable Construction: Built to withstand harsh environments and provide long-lasting operation.
