Water Polisher is an advanced stormwater treatment system utilizing an up flow media filter with built-in pre-treatment. Longterm maintenance of a stormwater BMP will eventually outweigh the initial cost. Storing waste solids in a dry state suspended in the basket minimizes maintenance costs by eliminating the need to remove thousands of gallons of water during the cleaning process. The Result Studies and historical performance data shows that a Nutrient Separating Baffle Box treating wet-weather flows will remove 86.9% of the total suspended solids, 47% of bacteria, and 99% of oils and grease.
The patented design provides double chambered separation to remove large to fine sediments from stormwater run off. This configuration prevents clogging challenges found with downward flow media filters.
Sediment Chambers: Maximizes TSS removal and eliminates scouring during high flow conditions.
Oil Skimmer & Booms: Collects hydrocarbons and controls flow velocity to improve up flow filter performance.
As water enters head pressure builds behind the internal weir to generate the force needed to operate the up flow filter. As water enters the system it passes over the first separation chamber settling out sediment. As water passes out the second separation chamber it encounters an oil skimmer which removes hydrocarbons before water is forced under the skimmer and into the up flow filter chamber. As water rises up it is forced through the media filtration bed for primary treatment before exiting the system.
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.
