VERDAFLO™
Biogas Conditioning & Combined Heat and Power Technology
BIOGAS TO ENERGY
Turning Wastewater-Derived Biogas into Renewable Electricity & Heat
VERDAFLO™ is our integrated biogas conditioning and energy-recovery technology, developed to convert the methane-rich biogas generated by anaerobic wastewater and organic-waste treatment systems into a reliable source of renewable energy.
Designed as the energy-recovery stage downstream of our AnoxyMedia™ and AnoxyWall™ anaerobic technologies, VERDAFLO™ receives raw biogas generated during biological COD conversion and prepares it for safe and efficient utilization.
The system integrates biogas collection, cooling, condensate removal, desulfurization, filtration, gas storage, pressure regulation, safety systems, and Combined Heat and Power (CHP) generation within a coordinated process platform.
After conditioning, the methane-rich biogas can be supplied to a CHP unit where it is converted simultaneously into electrical power and recoverable thermal energy. The electricity can offset plant or factory power consumption, while recovered heat can be reused for anaerobic reactor heating, hot-water generation, industrial processes, or other thermal demands.
VERDAFLO™ therefore transforms biogas from a treatment by-product into a valuable renewable-energy resource, helping industrial facilities reduce operating costs, fossil-fuel consumption, and overall carbon emissions.
WHY VERDAFLO™
Key Features & Benefits
From raw reactor biogas to grid-quality electricity and process heat – conditioned, stored, protected and automated.
Integrated Biogas Energy Recovery
Provides a complete solution for collecting, conditioning, storing, and utilizing biogas produced by anaerobic wastewater treatment systems.
Integration with AnoxyMedia™ & AnoxyWall™
Designed as the downstream energy-recovery platform for biogas generated by our high-rate anaerobic treatment technologies.
Biogas Collection & Management
Safely collects methane-rich biogas from anaerobic reactors and directs it through a controlled gas-treatment and utilization system.
Gas Cooling & Condensate Removal
Removes moisture and condensed water from raw biogas to improve downstream equipment protection and operational reliability.
Hydrogen Sulfide Removal
Dedicated desulfurization systems reduce H₂S concentrations, protecting CHP engines, boilers, piping, heat exchangers, and other downstream equipment from corrosion and sulfur-related damage.
Advanced Biogas Conditioning
Depending on raw-gas composition and final utilization requirements, VERDAFLO™ can incorporate gas filtration, drying, contaminant removal, and additional polishing stages.
Biogas Storage & Buffering
Gas-holder systems provide intermediate storage between variable biological gas production and energy-utilization demand, stabilizing the overall process.
Gas Pressure Regulation
Blowers, boosters, valves, and pressure-control systems maintain the required gas pressure and flow for reliable CHP operation.
Combined Heat & Power Generation
Conditioned biogas is utilized in a gas engine or CHP generator to simultaneously produce renewable electricity and useful thermal energy.
Renewable Electricity Production
Generated electricity can be used directly within the wastewater treatment plant or industrial facility, reducing dependence on externally supplied electrical power.
High-Value Heat Recovery
Thermal energy recovered from CHP engine cooling systems and exhaust gases can be reused for process heating, hot-water generation, or maintaining optimum anaerobic reactor temperature.
Anaerobic Reactor Heating Integration
Recovered CHP heat can be circulated back to the anaerobic treatment process, improving overall energy efficiency and helping maintain stable biological operating temperatures.
Reduced Treatment Energy Demand
Renewable energy generated from wastewater-derived biogas can offset part of the electrical and thermal demand of the treatment facility.
Energy-from-Waste Concept
Converts biodegradable organic pollution contained in wastewater and organic residues into useful renewable energy rather than treating it solely as a waste load.
Reduced Fossil-Fuel Consumption
Recovered biogas energy can replace a portion of conventional natural gas, diesel, or grid electricity consumption depending on the facility energy balance.
Reduced Greenhouse Gas Impact
Controlled collection and beneficial utilization of methane prevents uncontrolled release and maximizes the environmental value of anaerobic treatment.
Emergency & Excess Gas Flare
A controlled flare system can safely combust excess biogas during CHP shutdown, maintenance, start-up, or periods when gas production exceeds utilization capacity.
Biogas Safety Systems
Gas detection, pressure protection, flame arrestors, condensate traps, emergency isolation, ventilation, and other safety measures can be incorporated according to project requirements.
Real-Time Gas Monitoring
Instrumentation can continuously monitor parameters such as gas flow, pressure, methane concentration, H₂S concentration, oxygen content, temperature, and gas-holder level.
Fully Automated Operation
Integrated PLC/SCADA control manages gas treatment, storage, pressure regulation, CHP operation, flare control, alarms, interlocks, and energy-production monitoring.
Performance Monitoring
Electrical generation, thermal recovery, biogas production, methane content, CHP efficiency, and operating trends can be continuously recorded and evaluated.
Modular & Scalable
VERDAFLO™ systems can be engineered for small industrial installations through to large centralized wastewater and organic-waste treatment facilities.
Flexible Energy Utilization
Depending on project requirements, conditioned biogas can be utilized through CHP generation, boilers, thermal processes, or other suitable biogas-consuming equipment.
