Digestate dewatering of a biogas plant
In cooperation with the polymer manufacturer PRO-ENTEC we found a solution with good results to dewater digestates of a biogas plant. The conditioning of the sludge took place with polymers of PRO-ENTEC.
The pilot tests with a chamber filter press showed excellent results of solid-liquid separation on bio-sludge:
- high separation rate of bio-sludge (TS-concentration in filtrate less than 0,1%)
- nitrogen reduction in filtrate up to ca. 40 %
- phosphor reduction in filtrate
- dry content of filter cake up to ca. 30 %
Results of solid-liquid separation.
