Advanced Anaerobic Digestion/Biomass Pre-treatment

Methane Gas Yield Increase/Sludge Reduction in Wastewater Treatment Plants (WWTP)

Arisdyne’s controlled flow cavitation (CFC™) technology can significantly increase methane gas yield from the anaerobic digester by up to 30%. It also reduces sludge by up to 25% and improves dewaterability, significantly reducing energy and disposal costs.

Controlled flow cavitation breaks down sludge through destroying agglomerates, cell structures, and even cell walls and thus increases digestibility of biomass in anaerobic fermentation.

Economic value is provided by higher yield in methane gas (that can justify equipment for heat and power generation) and reduction in landfill/sludge hauling costs (by reducing the amount of sludge and water content in the sludge).

Reduction of Biomass Solids by Cavitation

The photos below (250x magnification) show the difference between CFC™ treated and untreated biomass "sludge." The photo on the left is uncavitated biomass sludge. The photo on the right is biomass after passing through Arisdyne's CFC™ equipment. CFC™ destroys cell structure providing increased digestibility of the biomass during fermentation.
