Stormwater treatment plant Hydrosystem 1500

The precipitation water treatment plant of the Hydrosystem 1500 type is installed in a plastic or concrete manhole with an internal diameter of 1.5 m at the factory.

A hydrodynamic separator causes the sedimentation of solids in a radial flow regime characterized by secondary flows. The action of the separator causes the solids to enter the flow-calmed sludge trap located below the separator hopper. Above the separator chamber are the six filter elements. The water passes through the filter elements in an upflow process. The system removes pollutants such as heavy metals, petroleum hydrocarbons and polycyclic aromatic hydrocarbons from the stormwater. It also binds nutrients such as phosphates. The quality of the treated water is so high that it can be discharged directly into groundwater or a surface water body. The difference in height between the inlet and outlet of this stormwater treatment system is only 25 cm, just like its little brother, the Hydrosystem 1500.

Since the stormwater treatment system is installed under the traffic surface, it does not require any additional space on the property or in the road space.

The stormwater treatment system can be used for traffic areas such as parking lots and roads of all traffic loads, industrial areas and metal roofs. The drain is equipped with a dip tube for light material retention. The sludge trap can be exhausted through the central maintenance pipe.
