3P Volume filter VF2

Industrial filter

Operating principle

  1. As water arrives the level builds up and overtops the filter lip, so ensuring it is distributed evenly across the whole width of the filter cascade.
  2. Pre cleaning through the cascades. Largest dirt particles are led across the primary filter cascades directly to the sewer.
  3. Pre filtered water then flows over the secondary filter sieve (Mesh size 0,4 x 1 mm). Due to the special mesh structure of the sieve, any dirt falls directly down onto the bottom of the shaft. In case of heavy rainfalls, the filter has more loss, as the water washes away the filtered dirt into the sewer.
  4. The cleaned water is being absorbed in the lower tank and directed through a tube DN 150 into the storage.
  5. Dirt goes to the sewer through the shaft.

Rainwater filter for bigger roof areas. Filter for installation in a concrete ring (Ø 1000 mm). Normally standard concrete shafts are used.

The filter can be delivered to the site yet pre-assembled on the shaft.

Two step cleaning system, therefore high level of filtering efficiency, independent of flow rate.

Due to the steep inclination of the filter cartridge the dirt is continuously cleaned away into the sewer. The connection to the sewer is installed on the shaft. The dirt falls down to the bottom of the shaft and is washed away with the next strong rainfall.

Relative connection capacity according to DIN 1986 for roof areas up to 850 m². Because of a Bypass-Installation a bigger area can be connected.

Filtertest

Average rainfall in Germany 80% less than 15 l (sxha), which results in a volume flow of 2.02 l / s with a roof area of ​​1347 m².

Pipe diameter: DN 200
max. flow: 40,4 l/s
connectable area at max. 200 l/(sxha): 2020 m²
connectable areas at max. 300 l/(sxha): 1347 m²

Application

Installation of a filter in a pilot shaft.

Installation of the filter in front of several concrete tanks which are situated in a row.
