Capture sediment, heavy metals, oil and nutrients from stormwater while reducing your site footprint and cutting maintenance costs.
The Up-Flo® Filter is an advanced stormwater treatment system that combines sedimentation and screening with filtration to deliver exceptional surface water pollution removal.
Verified to remove 80% TSS but with demonstrated removal rates up to 98%, only the Up-Flo® Filter was developed in collaboration with the US Environmental Protection Agency.
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.
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.
The Up-Flo® Filter's modular filtration components allow you to adapt your design to meet the needs of any catchment area, capturing the specific levels of trash, silt and sediment, oils, metals and nutrients required.
The Up-Flo® Filter combines pretreatment, screening and filtration, delivering highly efficient multi-stage treatment in one device.
The Up-Flo® Filter's higher loading rates result in a smaller treatment footprint, which saves construction time and money, and makes for an easier installation.
No moving parts means that there’s less opportunity for treatment disruption or breakage, while the system design is suited to long-term maintenance. Longer media life means you can go longer between servicings, and media bags are easily removed and replaced while media cartridge modules stay put during maintenance.
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.
Trash, gross debris and sediment settle out in the sump. Oil and ﬂoatables rise to the surface of the water.
Treated water ﬂows out of the Filter Module to the Outlet Module and into the outlet pipe.
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.
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.
