The StormPlex^TM is a modular storm water filtering unit that is optimized for the treatment of dissolved (soluble) and/or emulsified storm water pollutants.

The StormPlex^TM has minimal, solids handling capability and should be installed following some form of pre-treatment mechanism that removes: trash, debris, and a minimum 80% suspended solids.

A good application for the StormPlex^TM would be the treatment of runoff from a Golf green. Golf greens are designed to absorb water very quickly into deep, specially constructed under ground layers of high drainage materials.  After going through the layers the water is collected in a perforated pipe manifold system for transport away from the greens playing surface. In this situation, the water is very clean but can still contain high levels of dissolved phosphates, nitrogen compounds, herbicides and pesticides.

Simple Design
A single StormPlex^TM system consists of two basic components 1) An external, PVC housing that has been modified with an internal U-shaped track mount system and 2) A replaceable Fabco designed filtering cartridge.

StormPlex^TM units can be used individually or arranged in groups for increased flow/treatment capacity.

External housing
The cylindrical external housing, which is installed in a vertical orientation, is 18” in diameter and a minimum 5’ in height.

At the surface level, an 18” C.I. manhole cover provides access for inspection and for changing the cartridge.

Each housing also includes two pipe segments that allow the water to flow into then out of the filter. The segments can be manufactured in-line to eliminate height changes.

The PVC bodies provide many advantages:

They are designed to withstand heavy loads generated by traffic exposure (H-25)

They are immune to virtually all types of internal and external corrosion or other deterioration mechanisms that can attack underground structures

The lightweight material eliminates the need for heavy equipment reducing labor expenses and simplifying installation 

Easy-to-install gasketed push-on joints eliminate costly leakage problems that can be very common in structures made from other materials

Internal track mounting system
The external housing is modified internally by Fabco to accept a track mount system which will hold the filter cartridge “locked” in position

Insert the Cartridge
The Fabco filtering cartridge is installed through the manhole cover by aligning the edges of the filter cartridge with the U-shaped tracks in the external housing. Slide the cartridge all the way down until the sealing surfaces “clik” into place. To complete the cartridge installation, turn the locking handles to the filter position. Once locked into position, the cartridge body effectively bisects the column into 2 discrete chambers – An inlet and an outlet chamber.

Water flowing to the StormPlex^TM enters the “Inlet” chamber. Here it enters the filter cartridge through an opening or window located at the bottom of the cartridge body. As water continues to fill the Inlet chamber the water also rises upwards through the filter cartridge. This upwards flow provides an even, consistent path through the filter media with little chance for channeling or by-pass.

When this water reaches the top of the cartridge it is allowed out of another opening or window in the cartridge body into the outlet chamber. This treated water is then allowed out of the filter to pass on through the rest of the storm water system.
Two chambers separated by an up-flow filtering cartridge.

Fabco Technology Filtering Cartridges
Fabco builds the filtering cartridge based on the customer requirements using one or more of our proprietary filtering medias:

FABMAX – Hydrocarbon compounds

FABPHOUS – Phosphates and nitrogen compounds

FABGUARD – Pathogens and bacteria

FABSORD – Oils & Grease

FABLITE – Heavy metals       

Up-flow water treatment path
Each cartridge body has two cut-outs or windows to allow water to flow through the filter media. One window is located at the bottom of the filter which allows water into the cartridge while the other is located at the top to allow a path out of the cartridge for the treated water.
