how industries & cities circulate water & energy
Since 1977 we help a broad range of industries and cities worldwide to save and circulate both water & energy in the most sustainable way. We do this by converting their wastewaters, organic waste streams and CO2 to biomethane H2-C-H2 to replace fossil fuels for heat and power generation, to clean water for reuse and to active biofertilizer for healthy soils and crops. In this way, we help industries and cities to decarbonize and transit to clean energy and water at huge savings while getting more selfreliant and resilient.
As to achieve these objectives at the highest performance we developed and applied our most advanced and complementing bioprocess technologies AD+™ for bioenergy and AS+™ for clean water at full scale since 1980.
Our high-rate
mesophilic
AD+™ converts
CO2 to biomethane in
minutes
and a broad range of
wastewaters
in
hours while our high-rate
thermophilic
AD+™ converts
dry organic waste and slurries
in
a few days
to biomethane at up to 90% which is much faster and far more efficient than the low-rate mesophilic Anaerobic Digestion (AD) as currently applied in farm digesters and in other biogas plants worldwide.
Our proven
AD+™
bioenergy track record since 1980 with details on organic waste sources, loads and biopower yields is available upon request.
Our unique AS+™ technologies upgrade the core Activated Sludge (AS) process as used in more than 95% of all sewage and wastewater treatment plants worldwide with novel bioprocesses that capture, crack and biodegrade a wide range of recalcitrant organics from synthetic dyes and various “hard” organics such as PFAS down to the micropollutants such as in residual medicine API's and endocrine disruptors. In addition, our AS+™ add-in SNDN+™ bioprocess converts all nitrogen compounds most efficiently, via 50% nitritation (NH4 + to NO2 -) and anammox, directly to inert nitrogen gas N2 (80% in air). In this way, AS+™ biodegrades over 99% of all organics (as COD or TOC) as well as all nitrogen compounds (as total nitrogen TN) to very clean water for sustainable reuse. In this way AS+™ boosts the service life of the delicate NF/RO membranes by up to 5 times at the lowest total cost .
