Title: Filter system

Especially on large parking lots, rain washes oil and fuel into the ground, creating damage to the ground water. Since 1995 an innovative filter system whose main component is a highly effective and flexible active carbon filter mat has prevented the seepage of many tons of pollutant into thousands of drainage shafts in Austria and bordering countries. The patented filter mats are placed flat on the floor of a drainage shaft, where they filter the pollutants from the flowing water. As an additional advantage, the pair of filter fleeces the envelop the active carbon element are pinned together without any chemicals or adhesives; thus the filter mat can be used in ground water areas with no problems. These filter mats have proven themselves in many other application domains, including air filtration in hospitals and street shafts.
