Secondary treatment. A new approval for the BIONUT2 filter
For the rehabilitation of traditional wastewater treatment plants at reduced cost. SIMOP obtained on December 20, 2019 a new approval (2019-010-ext01 to ext13) for its range of filters "BIONUT2 FS" from 4 to 20 PE, only in secondary treatment.
This approval offers a more flexible and economical solution for rehabilitating traditional wastewater treatment systems in case of defective or end-of-life treatment.
Provided that the tank is still in good condition (structure and operation) and correctly sized, this new approval allows the installation of a compact filter with a "hazelnut shell" type filtering medium. A single filter is sufficient for the 4, 5, 6 and 8 PE filters.
From 10 to 20 p.e., sets of 2, 3 or 4 filters in parallel are to be installed at the outlet of the all-water tank, using the distribution manhole and the floating trough supplied as standard.
More precisely, the all-water pits already installed must comply with the Construction Products Regulation
The new range includes the following references:
- low outlet : BIONUT2/6054/04FS to 20FS
- high outlet : BIONUT2/6054/04FSSH to 20FSSH (with lifting station)
The filters are supplied with 150 mm extensions and lifting straps up to 8 PE. Beyond that, these accessories are optional.
