How does ANUBIX™ – T work?
In a typical plant, wastewater is first screened and then collected in a buffer tank equipped with an agitator. This tank is designed to allow sufficient qualitative and quantitative equalization and to acidify the wastewater partially. This allows for more stable operation and better sludge quality in the next stage: the ANUBIX™ – T anaerobic reactor. Provisions will be made for pre-settling of solids, heating, cooling, CO2 degasification, and inline neutralization if required as part of the overall process.
After passing through the second layer of anaerobic sludge (the so-called “sludge blanket”) the wastewater passes through the internal three-phase separator device at the top of the reactor.
The modular separator units are built-in stainless steel and GRP (Glass Reinforced Plastic) and are equipped with an additional cross-flow type parallel plate separator that ensures retention of even the smallest flocs of methanogenic sludge.
The clarified effluent leaves the reactor through a central collecting pipe. Biogas is collected at the top and conveyed for either further upgrading via scrubbing and drying, after which it can be fed to a utilization system such as an engine genset or boiler. Excess biogas is sent to an emergency flare.
At the project design phase, additional provisions can be foreseen for pre-settling of solids, heating, cooling, CO2 degasification, and inline neutralization, if required. The ANUBIX™ – T reactor is capable of handling very high loading rates of up to 25 kg COD/m³.d, depending on the type of wastewater.
