Pretreatment / Hydrolysis
Particularly aerobic sludge requires a long digestion time. With exposure to heat a better cell disruption and hence, an increased gas yield can be achieved. The digestion time is reduced at the same time.
- Thermal hydrolysis Lysotherm®
This process offers a cost-efficient and reliable sludge hydrolysis also in smaller waste water treatment plants (population equivalent > 30.000). The biological availability of surplus sludge is increased at temperatures of 100 – 175 °C.
The advantages are:
– Increased gas yield
– Increased dry matter content in dewatered sludge
– Reduzierung der zu entsorgenden Schlammmenge
- Thermal sludge pretreatment
Thanks to thermal sludge pretreatment at temperatures of 60 – 70 °C a partial cell disruption already takes place and this reduces the digesting time.
With sludge analysis we determine the optimal process for you.
