AMBREVO™ Technology

Above ground tank-based system designed to handle dilute (5,000 – 10,000+ mg/l COD) wastewater.

Produces an average of 18 MMBTU per milk cow per year.
Heated tanks with optimized heat exchange technology achieving year-round consistent gas production.
Viable option for flush dairies in cold northern climates.
Optimized process technology featuring unique mixing and solids management to provide robust, reliable performance.
Handles continuous flow; not a batch process.
Wasted sludge is routinely and easily removed for utilization (such as compost or land application).
Validated process model for designing reactor size and predicting biogas production based on influent characteristics.
Handles wastewater ranging from highly soluble to significant particulate COD fraction.

>2 days Hydraulic Retention Time and not HRT limited operating with solids retained in the system while liquids pass through.

17-20 days Solids Retention Time designed for optional digestion.
2.6+ kg COD/m3/day Organic Loading Rate. Demonstrated on flushed dairy manure with nearly complete digestion of the biodegradable fraction.

Incremental net present value from $4.3M to $6.9M (based on 3800 milk cow flush dairy).
Similar capital cost as a properly sized lagoon on smaller footprint.
Optimizes gas upgrading system by eliminating need to design for excessive peak summer flows and lower winter production.
Efficient effluent heat recovery and low electrical use.
Continuous handling and use of waste anaerobic sludge.
Incremental net present value from $800,000 to $5.5M depending on manure dilution (based on 4000 milk cow flush dairy).
Operations cost savings ranging from $120,000 to $600,000 per year (depending on manure dilution).
Reduced capital cost with smaller total reactor volume and potentially fewer reactor tanks.
Increased efficiency and value with more highly dilute manure, particularly for 100 gallons/milk cow/day or more.
