The Up-Flo Filter is the most efficient high-rate stormwater filtration technology available for the removal of trash, sediments, nutrients, metals and hydrocarbons from stormwater runoff. As the industry’s only fluidized bed upflow filtration technology, the Up-Flo Filter provides a higher level of treatment, a higher rate of filtration, longer life of filter media and a longer maintenance cycle than other filter systems.

Applications

• New developments and retrofits
• Industrial and commercial facilities
• Source control
• Sediment, hydrocarbon and nutrient control
• Heavy metals control
• Wetlands protection

Advantages

• Available in manhole, vault and retrofit configurations
• Higher flow capacity resulting in smaller systems
• Includes 4mm pre-screening
• Patented drain down prevents media degradation
• Easy installation and maintenance. Watch the animation to see the maintenance process.

• Variety of media options, including:

CPZ^TM  Mix    

Targets TSS and associated pollutants,  Nutrients, Bacteria, Metals and Organics.

View the animation or read below for an overview of how the Up-Flo Filter works.

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.

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.

Frequently asked questions

Q. What are the sizes available? What size do I need? What does it weigh?

The Up-Flo Filter is available in a standard 4-ft manhole configuration, in a precast concrete vault or without a concrete chamber for retrofit applications. The Up-Flo Filter is a very efficient device for removing fine sediments and other pollutants from stormwater runoff. The precise removal efficiency is dependent upon the particle size and specific gravity of the pollutant, in addition to the flow rate of the stormwater runoff. Please submit a request to our technical team for assistance selecting the appropriate model size and pick weights.

Q. Does the Up-Flo Filter remove oil and hydrocarbons? 

The Up-Flo Filter removes pollutants associated with stormwater runoff, including hydrocarbons found on roadways.  

Q. What size inlet/outlet pipe is acceptable?

Acceptable inlet/outlet pipe sizes vary by model configuration. Please refer to the sizing chart on the Up-Flo Filter flyer for acceptable pipe sizes.

Q. Can the Up-Flo Filter accept two inlets?

In some cases, yes, multiple inlets can be accommodated.  Please submit an inquiry for technical assistance.

Q. What is maintenance procedure for cleanout?  Is confined space entry required?  How often is maintenance needed?

The Up-Flo Filter was specifically designed to be easier and less expensive to maintain than other structural stormwater filters.  Maintenance consists of removing sediments, floatable trash, oils, and other debris from the sump with a standard sump vac or vactor truck. The media bags are easily replaced by hand. No heavy lifting equipment is required.  Disposal of captured pollutants should be carried out. Watch the animation to see the maintenance process.

Q. Does installation of the Up-Flo Filter require any special equipment or experience?

The installation process of an Up-Flo Filter is straightforward. The chamber is installed the same way as a standard concrete manhole.
