BIODIGAT®

Anaerobic wastewater treatment

WEHRLE offers a wide range of anaerobic treatment technologies for effluents and sludges with different COD and solids concentrations:

TSS über CSB
WEHRLE’s anaerobic technologies, TSS via COD

In order to treat the wastewater, we use our BIODIGAT® process technologies – see below.
For the fermentation of organic solids, we apply our BIODIGEST® technology.

BIODIGAT® SB: anaerobic sludge bed reactor (EGSB)

Very compact and efficient treatment technology for biogas generation from wastewater with dissolved COD


BIODIGAT® AF:  anaerobic fixed-bed reactor

Inexpensive alternative technology for wastewater with low content of solids


BIODIGAT® AS: anaerobic activated sludge reactor

This anaerobic treatment technology can also convert undissolved COD (fats, oils and organic solids) to achieve an ideal biogas yield.
