Pretreatment / Hydrolysis

Process

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.
