The new 3P Hydrofilter Drain offers a decentralized and absolutely new way for stormwater treatment. 3P Technik Filtersysteme GmbH offers a large product-range to collect, treat und harvest the rainwater and stormwater.
The 3P Hydrofilter Drain is the newest product of 3P and all the knowledge and all the gained experience of the past 10 years has merged in this product.
Decentralized stormwater treatment is becoming more and more interesting for
authorities and planners. It is seen as an important measure regarding the implementation of the Water Framework Directive, as it can be applied specifically and therefore cost-effective.
It is able to filter and bind pollutants like PAH´s, HC´s, heavy metals like Cd, Zn, Cu, Pb as well as phosphate and ammonium. The pollutants then can be disposed of specifically and easily. Thus the stormwater of highly frequented roads (parking sites and roads), industrial real estates and metal roofs can be cleaned directly on site and can be drained away or discharged into a surface water.
Owing to the modular concept of the Hydro-Gutter the stormwater is going to be cleaned in two steps:
Settle able particular solids were taken out Light-liquid and solute metals were adsorbed out of the stormwater.
Modular design for ecological line drainage
Based on the innovative filtration solution is the concrete channel nominal width of 300 mm. Planners are not used to make significant alternations in the drainage plan if they want to treat the water with the Hydro-channel.
The modular interior of the Hydro-channel:
1) The sedimentations box takes rough cleaning all solids such as stones, leaves and suspended particles on. The rubber lip ensures sealing around the edges – for the reliable differentiation for subsequent filtration.
2) The pre-treated rainwater is passes the granular-filter-pad and the organic and inorganic pollutants will be filtered from the water.
3) The filtered water flows over the baffle into the free flow area of the channel. It stands for reuse, seepage or discharge into rivers available.
After the preliminary cleaning in Sedimentation box the rainwater enters into the Filter unit. The pre purified and filtered water flows over the baffle into the gutter.
The already in the Sedimentations box pre-treated rainwater is passed through a filter pad with granules. By adsorption and precipitation organic and inorganic pollutants will be removed. The purified water is than flowing to a collection point where it could be further used or discharged in seepage. Because of the rough cleaning in the sedimentation box the functionality remains of high quality filter granulate get a long time.
To ensure a homogeneous particle distribution, the granules are involved in the fine-grained filter-pad. A segregation of granular pack is as good as impossible.
The filter pad has to be replaced every 10 years on average.
