Sewage Sludge to Power
Turn dried sewage sludge into clean gas for power and heat, on site, in one container.
Sludge is costly to get rid of
Every wastewater treatment plant produces tonnes of sewage sludge every day. Most of it is trucked away, spread on fields, or sent to a large incinerator far from town. That costs money, diesel and time.
Treat it where it is made
The X-150 is a containerised gasifier that sits beside your plant. Dried sludge goes in; a high-temperature reactor bed turns it into clean gas. The gas runs an engine for power, and the recovered heat can dry the next load of sludge.
How it works
Dewatered sludge is dried to 15% moisture or less, using the X-150's own recovered heat where possible.
A top-blown, single-stage reactor bed at about 1,000–1,100 °C converts the sludge into gas, without burning it.
The gas is filtered and cooled, clean enough for engines.
A gas engine turns it into electricity; heat is recovered for drying, heating or cooling.
Built for high-ash waste
Sludge is full of ash. At high temperature the ash melts, hardens into clinker and chokes most gasifiers. Our team in Germany spent twenty years on this one problem. In the X-150, a poker from above and water-cooled rollers below remove the slag while the reactor keeps running.

Figures are rated values. Site performance depends on the sludge and the project design.
