Up-Flo^® Filter is an advanced stormwater best management practice (BMP) that combines sedimentation and screening with filtration to capture sediment, oils, heavy metals and nutrients from stormwater runoff, achieving total suspended solids (TSS) removal rates of up to 98%.

Up-Flo^® Filter is a flexible, high-performance treatment solution that can be customized to meet US National Permit Discharge Elimination System (NPDES) requirements specific to a municipality or state. Designed with efficiency, longevity and upkeep in mind, the Up-Flo^® Filter has high loading rates and long media life, which means you'll get high quality water treatment for longer periods between servicings.

Targeted pollutants

• Very fine particles
• Trash and floatables
• Liquid and sediment bound hydrocarbons
• Sediment bound heavy metals
• Sediment bound nutrients

Applications

The Up-Flo^® Filter is perfectly suited to industrial sites, locations contributing runoff to wetlands/protected regions, or any area requiring a high level of treatment.

• Remove solids, nutrients and metals from runoff
• Source control for redevelopment or new construction
• Treatment of Water Quality Volume detention systems
• Sites operating under industrial or multi-sector general permits
• Low-impact development (LID), sustainable drainage (SuDS), LEED^® and water-sensitive urban design (WSUD) projects

1. Stormwater enters the chamber via an inlet pipe or inlet grate and fills the chamber, as flow is directed up through the angled screen and Filter Modules.
2. Trash, gross debris and sediment settle out in the sump. Oil and floatables rise to the surface of the water.
3. Treated water flows out of the Filter Module to the Outlet Module and into the outlet pipe.
4. Excess flows are discharged to the outlet using a Siphonic Bypass, which also acts as a floatables baffle preventing the escape of oil and floatable trash.
5. To guard against pollutant leaching and filter media degradation between storm events, water drains out of the chamber through the filtered Drain Down Port as the storm subsides.
