FILTREXX ENVIROSOXX POLLUTANT REMOVAL FILTER SOCK

Filtrexx EnviroSoxx Pollutant Removal Filter

Pollutant Removal - EnviroSoxx stops pollutants from leaving your site.

EnviroSoxx® is the most versatile and cost effective filter for storwater pollutant removal. A passive filtration system ready to install on any site, EnviroSoxx targets the most common pollutants in stormwater runoff, particularly in urban watersheds, sensitive receiving waters, and Total Maximum Daily Load - TMDL (§303d) listed water bodies. EnviroSoxx help industrial stormwater permit holders/MS4s comply with their permits, easily and quickly. EnviroSoxx can be applied on bare soil, vegetation, or impervious surfaces in the path of sheet flow or concentrated flow to target stormwater pollutants.

TESTING & REMOVAL EFFICIENCY

EnviroSoxx is available in two filter blends to target common pollutants.
Advanced Blend: Targets a range of heavy metals, hydrocarbons, nutrients, and sediment. Also targets pH.
Industrial Blend: Targets bacteria, nutrients, hydrocarbons, select heavy metals, and sediment.

Removal efficiency test results vary by pollutant and are based on third-party and in-house research.

Actual removal rates are highly dependent on site specific environmental conditions including:

  • flow rate
  • flow volume
  • pollutant concentration
  • pollutant load
  • proper installation
  • maintenance
  • design
  • sampling methods

Filtrexx uses multiple test methods to assess EnviroSoxx pollutant removal efficiency. See Removal Efficiency References below for individual pollutant testing. Actual removal rates may vary and are not guaranteed.

Contact Filtrexx for design guidance based on your specific site conditions.

MULTIPHASE FILTRATION DESIGN: DOUBLE REMOVAL EFFICIENCY*

The design and installation of multiple EnviroSoxx in a single application can significantly increase pollutant removal performance.  New research provides science-based evidence that this technology can be a very effective best management practice and storm water treatment system used in a comprehensive treatment train design approach to meet a variety of industrial and municipal stormwater permit requirements. Space EnviroSoxx 12 inches apart for Multiphase Filtration Design.

On average, double your removal rates with three EnviroSoxx filters.

*See Research Reference TechLinks #3343 and #3344. Based on removal efficiency averages of select pollutants.

EnviroSoxx Multiphase Filtration Design

TREATMENT TRAIN DESIGN

When designing a passive filtration system, water gets cleaner as it passes through multiple filters – therefore a combination of inlet protection, runoff diversion, channel protection, and outfall filtration using EnviroSoxx is typically recommended.

EnviroSoxx can also be stacked in a pyramid style to increase the capacity of the system. As this illustration shows, each number represents a different EnviroSoxx application in a Treatment Train approach.

3-WAY BIOFILTRATION

EnviroSoxx contains compost FilterMedia™ plus natural sorbents used to increase pollutant removal capacity, and to reduce pollutant transport in runoff and absorption by plants. EnviroSoxx is filled with all natural materials.

When designing a passive filtration system, water gets cleaner as it passes through multiple filters – therefore a combination of inlet protection, runoff diversion, channel protection, and outfall filtration using EnviroSoxx is typically recommended. EnviroSoxx can also be stacked in a pyramid style to increase the capacity of the system. Replacement of EnviroSoxx filters is designed according to site conditions, but is typically recommended on a quarterly basis.

Biofiltration is a technique to control pollution by using living material to capture and biologically degrade process pollutants. A 3-way biofiltration system entails the following areas:

  • Physical: it traps sediment in matrix of varying pore spaces and sizes
  • Chemical: it binds and adsorbs pollutants in storm runoff
  • Biological: it degrades various compounds with bacteria and fungi

STORMEXX CATCH BASIN FILTER

Pair EnviroSoxx with StormExx® CLEAN Catch Basin Filter for under the grate treatment train.

StormExx CLEAN catch basin filters are designed to fit any existing stormwater drain system to capture sediment and pollutants.  StormExx uses filtering media and additives in a replaceable cartridge for under the grate stormwater treatment.
