DRAINFIX CLEAN

Filter substrate channel for effective treatment of polluted surface water.

Your benefits with DRAINFIX CLEAN

DRAINFIX CLEAN has the unique ability to collect, filtrate and drain surface water before it is discharged into sewer networks or natural watercourses. The system consists of a CARBOTEC 60 filter substrate which efficiently treats pollutants found in surface water run-off such as rubber particles, hydrocarbons, heavy metals and other contaminants.

Manufactured from fibre-reinforced concrete for extra strength and stability against extreme heavy loads, the system can withstand traffic up to an F 900 loading class. DRAINFIX CLEAN is an ideal surface water treatment system for locations subject to pollutants such as heavily trafficked areas and industrial facilities.

  • CARBOTEC 60 filter substrate is characterised by a high carbonate content and good binding of dissolved heavy metals and retention of ultra-fine particles (0.006 to 0.060 mm)
  • Long maintenance intervals: first inspection after 10 years (depending on local conditions) with only the filter cake needing to be removed/refilled with the substrate
  • Efficient treatment of TSS (total suspended solids) 99.5%, TPH (total petrol hydrocarbons) 99.9%, 99.8% zinc and copper
  • Ideal for use in heavily built-up areas and surfaces subject to traffic: Lower land consumption allows more usable building area
  • Featured in the CIRIA SuDS Manual C753 under chapter 14: proprietary treatment systems: for developing a resilient, robust and assured SuDS scheme
  • Approved by German Institute for Building Technology (DIBt) Z-84.2-7

Installation and maintenance of the filter drainage channel

DRAINFIX CLEAN combines low installation costs for stormwater treatment with maximum safety for traffic areas. The installation is extremely simple as the only additional components are the filter substrate and pipe connection which are inserted into the channel.

1. Installation of the channel body

Easy installation with the FASERFIX SUPER channels

2. Filter pipe tubes inserted into the channel

Made of highly resistant PEHD plastic

3. Filling of the CARBOTEC 60 filter substrate

For an efficient filtration for pollutants   

4. Align the substrate with levelling device

For reliable maintenance of the filling level  

5. Attach the grating

Time savings with the SIDE-LOCK boltless locking system  

Long maintenance intervals

The maintenance of the drainage system is very minimal given the time the layer cake will build up. Only when 1/3 of the retention space is filled up, will the filter cake need to be removed. If necessary, the filter substrate can be refilled back into the system. With long maintenance intervals of up to 10 years (depending on local conditions), this makes for a simple and cost-efficient rainwater treatment system.

Connection options

Channel

Following treatment by the DRAINFIX CLEAN system, there is the option of connecting to a sewer.

Parallel seepage line

A seepage line can be laid parallel to the DRAINFIX CLEAN channel, into which the water is discharged after cleaning.

Stockholm system

Especially in urban areas, the wastewater from the streets can be effectively treated and subsequently used for tree watering.
