FilterSmart Gravity Filter Backwash Monitor

Revolutionary Backwash monitoring
ATi’s FilterSmart Backwash Monitor is revolutionizing the way water professionals manage their gravity filters. FilterSmart allows water managers to ‘see’ into backwash processes with media level and turbidity measurements in one sensor.

More than flow rate and time
Until now, operators have relied on two surrogate measurements to manage the backwash process: flow rate and time. FilterSmart directly measures the parameters of actual interest: media expansion and turbidity. These two trends together present a clear picture of what’s going on during the backwash, allowing operators to ‘see’ into the process like never before. FilterSmart simplifies filter optimization because its 24/7 monitoring takes the place of countless manual hours of data collection.

Measure level of media and turbidity
The FilterSmart sensor is located in the top of a gravity filter just below the top of the wash trough. During a backwash, the ultrasonic sensor tracks the level of the media and the turbidity sensor measures how clean or dirty the wash water is as it flows into the wash trough. These two measurements produce trends that together provide an extremely accurate profile of the backwash and become a powerful tool for optimizing filter performance. Equipped with this insight, operators can virtually eliminate media loss and mud-ball formation, in most cases reduce water usage, and improve overall filter health and efficiency.
