PRETX

PRETX

A Pretreatment Debris Filter

Extend the operating life and reduce the maintenance burden of biofiltration systems by filtering out trash and debris at the inlet. PRETX enables the simplified maintenance of biofiltration systems at the inlet in an accessible location with no special equipment required. The absence of a pre-filter may allow trash and debris to prematurely clog the biofilter media or infiltration bed. The rapid accumulation of trash and debris can require frequent maintenance for aesthetics in high-loading land uses and reducing the filtration rate. Installation is simple and would be comparable to common catch basins and grates and requires no special tools or training.

PRETX is available in several different configurations and enables the simplified maintenance of green infrastructure systems at the inlet in a deep sump catch basin that is accessible and requires no specialized maintenance equipment. The absence of a pre-filter may allow sediment, trash, and debris to prematurely clog the biofilter media or infiltration bed. Surface accumulation of trash and debris can require frequent maintenance for aesthetics in high-loading land uses and reduce the infiltration rate of filtration media. Installation is simple and comparable to common catch basins and grates.

Benefits

  • Available in two models that manage most biofilter inlet configurations: Curb and Drop
  • RETX-Curb is for the edge of pavement runoff at a curb cut in replace of a stone spreader
  • PRETX-Drop is for use as a drop-inlet configuration along a curb line and would be installed with a standard drop-inlet grate
  • Sized to pretreat water quality flows and bypass larger ones.
  • This keeps the size of the system smaller than if it were to pretreat larger flows that have minimal trash and debris
  • Can be used both in retrofit or new installations
  • Keep your biofilters, bioretention, and subsurface infiltration systems clean
  • Made of precast concrete (HDPE) and stainless steel, PreTx is resistant to rust and rot from corrosive winter runoff.
  • Maintenance of preTx is simple and utilizes standard vactor trucks to catch Basin cleaning. Simply remove the inspection cover and remove debris by use of a pressure washer and vacuum.
  • PreTx Has a 1 to 2-year return on investment by reduction of biofilter maintenance if used in locations with moderate to high trash and debris loads such as commercial and residential areas.
