Secondary wastewater treatment
Bifena
When a grease separator alone is not enough: after treatment,
wastewater draining out of a properly sized and certified EN
1825 grease separator normally has a residual value of lipophilic
substances of approx. 300 mg/l. If the municipalities require a
limit value of below 300 mg/l, biological grease treatment with
a Bifena unit is needed. It removes residual grease from the
wastewater with the help of bacteria.
Bifena units are available for free-standing or underground
installation. The individual dimensioning is based on a waste-
water sample analysis to determine what additional treatment
measures need to be taken to meet local wastewater limits.
Contact us – we will be happy to advise you and develop an
individual solution for your specific requirements.
On the other hand, it may be necessary for chemical substances
to be added. In this case a dosing station is advisable, with which
the correct quantity of chemicals can be added to the separator.
The unit consists of a mixing and a dosing station and can be
installed near the separator.
