Volume Filters

3P Volume Filter VF3

Rainwater filter for bigger roof areas. Filter for installation in a concrete ring (Ø 1200 mm). Normally standard concrete shafts are used. The filter can be delivered to the site yet pre-assembled in the shaft.

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

Description

Rainwater filter for bigger roof areas. Filter for installation in a concrete ring (Ø 1200 mm). Normally standard concrete shafts are used. The filter can be delivered to the site yet pre-assembled in 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 at the shaft. The dirt falls down on 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 1100 m². Because of a Bypass-Installation a bigger area can be connected.

Max. Flow Rate Sieve insert 4,5/sec
= 16,2 m³ cleaned water per hour.

Inlet rainwater 2 x DN 200
Outlet into storage DN 150
Outlet into sewer DN 200
Height difference between inlet and outlet 320 mm.

The filter has to be cleaned depending on the contamination 1 – 2 times during the year.

How it works:

  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.

The 3P Volume Filter VF3 has only one fin unit. On the opposite a baffle is mounted.
