Industrial wastewater streams often carry high organic loads and fluctuating flow rates, making them challenging to treat using conventional anaerobic systems. Modern solutions integrate multiple reactor configurations, such as UASB, fixed-film and hybrid designs, to achieve efficient solids retention, enhanced digestion rates and stable methane recovery.
Within this suite, Anaerobic Hybrid Reactors (AHR) are deployed selectively where combined sludge blanket and fixed-film treatment is beneficial. These systems support high-rate anaerobic digestion of sewage sludge and industrial effluent, improving energy recovery and reducing operational disruptions in variable conditions.
High-density granulated biomass supports stable microbial populations even during load shocks.
Generates methane-rich gas suitable for use in biogas engine power plants or for upgrading to CBG (Compressed Biogas).
Structured media promotes immobilized biofilm formation, increasing reaction surface area and stability.
Units can be expanded or downsized based on load, space and treatment goals.
Can be integrated with SCADA water and wastewater systems for real-time performance analytics.
The Anaerobic Hybrid Reactor features a dual-zone structure with a suspended sludge bed in the lower chamber and attached biofilm media in the upper zone. This hybrid configuration enhances microbial diversity and process resilience, making AHR ideal for industries managing high-COD wastewater, toxic influents or inconsistent flow.

Looking to reduce treatment costs and generate your own power from waste? Talk to the WOG Technologies Limited team about deploying an Anaerobic Hybrid Reactor customized for your site, load and sustainability goals.
The AHR offers enhanced stability due to its fixed-film zone, allowing higher organic load handling and more resilience to shock loads than standard UASB or EGSB systems.
Yes. The methane-rich gas generated can be used in biogas electricity generation systems such as CHP (Combined Heat and Power) or for CBG production, enabling circular energy models.
WOG’s AHR supports both mesophilic and thermophilic operations, depending on the site’s energy strategy and sludge characteristics.
Due to its granular retention and enhanced digestion, sludge generation is lower. Sludge can be further stabilized and dewatered for reuse or disposal.
Our AHR units can be integrated with SCADA water and wastewater platforms, enabling real-time control, alarm triggers and predictive maintenance analytics.
