DRAINFIX CLEAN

Filter substrate channel for effective treatment of polluted surface water.

Drainfix Clean

Your benefits with DRAINFIX CLEAN

The DRAINFIX CLEAN filter substrate channel is an intelligent drainage solution that collects, filters and drains rainwater. The system consists of the CARBOTEC 100 filter substrate and a drainage channel with drainage pipe. Different FASERFIX or RECYFIX variants can be used depending on the type of load. The filter substrate channels are designed for loads up to F 900.

  • Retention volume of 15 to max. 137 litres/running metre of channel offers safety during heavy rainfall events
  • With DIBt approval Z-84.2-7 and can be planned in accordance with the requirements of DWA-A 138/DWA-A 102/DWA-M 153 for maximum planning and operational safety
  • Ideal for use in heavily built-up areas and surfaces subject to traffic: Lower land consumption allows more usable building area
  • CARBOTEC 100 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)
  • Extremely long maintenance intervals: first inspection after 10 years (depending on local conditions)

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.
