Surface water created by heavy rainfall, melting snow or ice can contain pollutants. Roads, car parks and other surfaces are continually exposed to a variety of pollutants including heavy metals (zinc, lead, copper), microplastics, hydrocarbons, oils and sediment.
Surface run-off can wash these pollutants into natural watercourses and sewer networks, which imposes harm to the environment and our fragile ecosystem.
To prevent pollutants or harmful substances from entering watercourses, oceans or sewerage, surface water run-off must be treated at the source before it reaches other outlets.
A surface water treatment solution such as a drainage and filtration system can manage surface water, whilst capturing pollutants and improving the overall water quality.
Surface water passes through a filter substrate, which is designed to capture pollutants, allowing purified water to be discharged. The substrate addresses specific pollutants that are present within the particular environment. This can range from heavy metals and oils on industrial yards to rubber granulate on artificial turf.
Characteristics of surface water treatment systems
Loads and forces
As drainage and filtration systems are beneficial for industrial environments, thesystem must be capable of withstanding traffic loads and patterns in line with the proposed use. This can include anything from extreme heavy loads, high speeds, slow moving traffic, dynamic and lateral forces and transverse movements, etc.
As numerous vehicles traffic surface water treatment systems, they must have the capability to cope with continual traffic with varied wheel types and configurations.

Filter substrate channels for rainwater treatment
The DRAINFIX CLEAN system with a CARBOTEC filter substrate has been specially developed to meet the requirements of rainwater treatment for traffic areas – with outstanding results:
Total suspended solids (TSS) 99.5%
Total petroleum hydrocarbons (TPHs) 99.9 %
Zn (Zinc) 99.8%
Cu (Copper) 99.8%
Filter substrate CARBOTEC 60
In order to effectively retain microplastics and micro-rubber from tire abrasion, the CARBOTEC substrate was developed with a specially designed filter resistance. The finest particles are retained right from the start of filtration. This ensures that the cleaning performance works with large connecting surfaces and heavy rainfall.
High carbonate content (carbonate reserve for many decades)
Precipitation/binding of dissolved heavy metals
Retention of very fine particles (0.006 to 0.060 mm)
