Hydrosystem 1000

3P Hydrosystem 1000 Roof

Specialist rainwater filter for installation within standard manhole shafts, 1000mm diameter. The ready-to-install Hydrosystem 1000 is quickly and safely installed on site. Suitable for roof areas up to 1000m². The cleaned water has such an excellent water quality that it can be discharged directly into soakaways, surface waters and the wider environment. The filter function is an up-flow process and this allows for a design with a minimal height difference between the inlet and outlet. In the filter shaft the rainwater is cleaned by basic operation of the following processes: Sedimentation, Adsorption, Filtration, and Chemical Precipitation.

Description

Specialist rainwater filter for installation within standard manhole shafts, 1000mm diameter. The ready-to-install Hydrosystem 1000 is quickly and safely installed on site. Suitable for roof areas up to 1000m². The cleaned water has such an excellent water quality that it can be discharged directly into soakaways, surface waters and the wider environment. The filter function is an up-flow process and this allows for a design with a minimal height difference between the inlet and outlet. In the filter shaft the rainwater is cleaned by basic operation of the following processes: Sedimentation, Adsorption, Filtration, and Chemical Precipitation.

Incoming rainwater is led down to the basal section of the filter shaft. A hydrodynamic separator built in the base section promotes particulate sedimentation. The water is led into this separator tangentially and generates a radial flow pattern. Particles settle into the silt trap located below the separation chamber. Above the separation chamber are 4 filter elements, occupying the full shaft width such that all water must flow up through the filter. The Siltation of this filter is slow due to the upwards flow, and the fact that the filter is below the water level. The filter is easily exchanged. Under normal conditions the filter will last for 2 years, maintenance free.

How it works:

  1. The rainwater from the connected area is fed into the basal section of the filter housing. The angled inlet generates a radial flow pattern.
  2. The hydrodynamic separator converts turbulent waters into a radial laminar flow pattern, generating particle sedimentation, particularly of the sand fraction.
  3. This takes place over an inlet to the lower section of the filter shaft. The sediment is retained in a silt trap chamber below the separator. The silt trap needs to be emptied out at intervals.
  4. In the central section of the filter housing is the actual filter, Filter Element: Metal. The filter element filters out the fine materials in an up-flow process and dissolved materials are precipitated and adsorbed. The filter is backwashed from above. When exhausted the filter is easily exchanged.
  5. The filter element is easily pulled up via shaft openings.
  6. Above the filter element is the clean water. It passes via an oil separator and then flows via the outlet into soakaways and so on.
