AnoxyMedia™
High-Rate Anaerobic Treatment Technology
HIGH-RATE ANAEROBIC
High-Performance COD Removal, Biogas Recovery & Compact Anaerobic Treatment
AnoxyMedia™ is our advanced high-rate anaerobic methane-fermentation technology, engineered for the efficient treatment of high-strength industrial wastewater with a combination of high COD removal performance, compact reactor footprint, low energy demand, and renewable biogas generation.
The technology utilizes highly active anaerobic microorganisms to convert biodegradable organic pollutants into methane-rich biogas, significantly reducing the organic load of industrial wastewater while recovering part of its chemical energy as a renewable resource.
AnoxyMedia™ is not based on a single reactor configuration. Instead, the process is engineered according to the characteristics of each wastewater stream, particularly COD concentration, suspended-solids content, wastewater temperature, biodegradability, and hydraulic loading. Depending on these conditions, AnoxyMedia™ can be configured as a high-rate EGSB, UASB, or Downflow Attached Growth (DAG) anaerobic treatment system.
For relatively low-TSS industrial wastewater requiring very high volumetric treatment capacity, AnoxyMedia™ EGSB provides intensive contact between wastewater and granular anaerobic biomass within a compact reactor, supported by high-capacity solids separation.
For wastewater containing higher suspended-solids concentrations or where granular-sludge processes are less suitable, AnoxyMedia™ DAG utilizes an anaerobic attached-growth carrier system that retains active biomass on specially designed media and provides stable treatment under demanding industrial conditions.
This flexible technology platform enables us to select the most appropriate anaerobic treatment concept rather than forcing every industrial wastewater stream into a single reactor configuration.
WHY ANOXYMEDIA™
Key Features & Benefits
High-rate anaerobic conversion, flexible biomass retention and renewable biogas – matched to each industrial wastewater stream.
High-Rate Anaerobic Treatment
Maintains a high concentration of active anaerobic biomass, allowing significant organic loading and COD removal within a comparatively small reactor volume.
High COD Removal Performance
Effectively converts biodegradable COD into biogas, substantially reducing the organic load requiring downstream treatment.
Methane-Rich Biogas Production
Converts organic pollution into renewable biogas containing methane, allowing energy recovery where project scale and operating conditions make utilization economically attractive.
Compact Reactor Footprint
High biomass retention and high volumetric organic loading rates enable significantly greater treatment intensity than conventional low-rate anaerobic systems.
Multiple Reactor Configurations
Available as EGSB, UASB, and DAG attached-growth configurations, allowing the biological process to be optimized for the actual wastewater characteristics.
AnoxyMedia™ EGSB
Expanded Granular Sludge Bed technology provides intensive wastewater-to-biomass contact and high-rate treatment for suitable soluble and low-to-moderate suspended-solids industrial effluents.
High-Capacity Solids Separation
EGSB configurations incorporate effective biomass-separation arrangements to retain valuable anaerobic granular sludge within the biological reactor.
AnoxyMedia™ UASB
Upflow Anaerobic Sludge Blanket configurations provide robust anaerobic treatment for suitable industrial wastewater where hydraulic and organic loading conditions favor conventional granular-sludge operation.
AnoxyMedia™ DAG – Downflow Attached Growth
Uses anaerobic carrier media to retain microorganisms as an attached biofilm, providing an alternative solution where wastewater characteristics make granular-sludge reactors less suitable.
High Biomass Retention
Both granular and attached-growth configurations maintain a substantial active microbial population within the reactor, allowing long effective biomass retention times.
Adaptable to Wastewater TSS
Reactor selection is optimized according to suspended-solids concentration, with granular-sludge and attached-growth systems selected according to the characteristics of the individual industrial effluent.
Temperature-Optimized Design
Reactor configuration and loading criteria can be adapted according to wastewater temperature and the biological activity available under actual operating conditions.
Robust Industrial Performance
The process is designed to tolerate variations in organic loading, wastewater composition, hydraulic conditions, and industrial production cycles.
Reduced Aeration Energy
Since the primary biological conversion occurs under anaerobic conditions, the process eliminates the intensive aeration requirement associated with conventional aerobic COD removal.
Low Excess Sludge Production
Anaerobic biological conversion generates substantially less excess biomass than conventional aerobic treatment, reducing downstream sludge-treatment and disposal requirements.
Reduced Downstream Biological Load
Significant upstream COD removal reduces the oxygen, reactor-volume, and sludge-production requirements of any subsequent aerobic biological treatment stage.
Energy Recovery Potential
The methane contained in the generated biogas can be recovered for boiler fuel, heating, combined heat and power generation, or other suitable energy applications.
Modular & Scalable
Reactor systems can be engineered for different industrial capacities and can be expanded according to future wastewater flows and production requirements.
Process-Specific Engineering
Each system is selected and designed based on wastewater biodegradability, COD fractionation, TSS, temperature, hydraulic loading, organic loading, and required treatment objectives.
Fully Automated Operation
PLC/SCADA-based control can continuously monitor feed conditions, reactor operation, flow, temperature, pH, recirculation, biogas production, alarms, and overall biological performance.
ONE PLATFORM, THREE REACTORS
AnoxyMedia™ Reactor Configurations
The selected EGSB, UASB, or DAG configuration is determined by the wastewater characteristics and the required process performance.
AnoxyMedia™ EGSB – Expanded Granular Sludge Bed
The EGSB configuration is designed for high-rate treatment of biodegradable industrial wastewater using dense anaerobic granular biomass.
High upward liquid velocity and controlled recirculation create intensive contact between wastewater and the anaerobic granules, allowing high organic loading rates while maintaining a relatively compact reactor.
Best suited for:
- High-strength biodegradable industrial wastewater
- Predominantly soluble COD
- Low-to-moderate suspended-solids loading
- Applications requiring very high volumetric treatment capacity
- Industries seeking maximum COD reduction with minimum footprint
AnoxyMedia™ UASB – Upflow Anaerobic Sludge Blanket
The UASB configuration utilizes an anaerobic granular-sludge blanket through which wastewater flows upward, allowing organic contaminants to contact and be converted by the retained anaerobic biomass.
It provides a proven, robust treatment approach for suitable high-strength industrial wastewater applications.
Best suited for:
- Biodegradable industrial wastewater
- Moderate hydraulic loading
- Applications suitable for granular anaerobic biomass
- Facilities requiring reliable and relatively simple high-rate anaerobic treatment
AnoxyMedia™ DAG – Downflow Attached Growth
The DAG configuration uses specially designed anaerobic carrier media on which microorganisms establish an attached biological film.
Rather than depending on formation and retention of granular sludge, active anaerobic biomass is maintained on the carrier structure, providing increased process flexibility where wastewater characteristics, suspended solids, or operating conditions make conventional granular-reactor technology less suitable.
Best suited for:
- Wastewater containing elevated suspended solids
- Industrial effluents unsuitable for conventional granular-sludge reactors
- Applications requiring stable attached biomass retention
- Variable industrial wastewater characteristics
- Anaerobic retrofits and process intensification
RETROFIT & UPGRADE
Repowering Existing Aerobic Treatment Plants
A major application of the AnoxyMedia™ platform is the conversion or repowering of existing aerobic wastewater treatment facilities into anaerobic or combined anaerobic-aerobic treatment systems.
AnoxyMedia™ attached-growth configurations can be incorporated into suitable existing infrastructure to introduce high-rate anaerobic COD removal upstream of, or within, an existing treatment concept.
This approach can provide significant benefits including:
- Reduced aeration demand
- Reduced electrical energy consumption
- Lower excess sludge production
- Increased organic treatment capacity
- Reduced loading on existing aerobic reactors
- Potential renewable biogas generation
- Improved utilization of existing civil infrastructure
- Reduced requirement for construction of additional treatment tanks
