Introduction to DynaSand® Filtration
Filtration through sand is an ancient and cost-effective method for removing impurities from water. DynaSand® revolutionizes this process by offering continuous filtration, eliminating the need for backwashing, and providing a reliable and efficient solution for water treatment.

Advantages of DynaSand®

• Continuous operation without interruption for backwashing.
• Always clean effluent with no first filtrate.
• Handles high suspended solids without pretreatment.
• Low head loss and energy consumption.
• Minimal supervision and maintenance costs.

System Simplification

• No need for backwash pumps or storage tanks.
• No automatic valves or air scour blowers.
• Single media filter bed with no clogging nozzles.

Operational Mechanism
The DynaSand filter operates on a counterflow principle, where water is cleaned as it flows upwards through a sand bed. The sand is continuously cleaned by an internal washing system, ensuring uninterrupted service.

Design and Installation
DynaSand filters are available as freestanding units or modules for concrete basins. They can be customized in various models, sizes, and materials to suit specific applications.

Applications

• Drinking water treatment and industrial water supply.
• Process water recycling and wastewater treatment.
• Tertiary filtration for municipal and industrial effluents.
• Metal-bearing industrial effluent treatment.

Integration with Johnson Lamella Separator
The DynaSand filter can be combined with a Johnson Lamella separator for an integrated water treatment system, optimizing space and reducing costs.
