Up Flow Filter: Removes fine TSS, metals, nutrients and bacteria with an advanced sorptive media filtration bed.
Passive Self-Cleaning: Up Flow Filter is passively back washed with drain down filters.
Once flow into the system subsides, the water level in the system will start to fall. Once the water level reaches the upper effluent side of the up flow filter it can no longer discharge. The remaining water within the filtration media is forced downward as the drain down filters continue to treat and discharge stormwater. This passive back wash action releases pollutants that would otherwise contribute to long-term clogging and performance issues.
