AnMBR LETM - ANAEROBIC MEMBRANE BIOREACTOR
Maximising COD Removal and Biogas Production
ANAEROBIC MEMBRANE BIOREACTORS
As pressure intensifies to reduce medium and long term operational costs, anaerobic processes are becoming increasingly attractive and economical in many applications. For situations where higher rate and granular sludge based AD processes are not appropriate (e.g. those with very high COD concentrations, high TSS, FOG and salinity) or a customer is looking to maximise organic conversion and gas cogeneration, anaerobic MBRs can provide a cost effective solution.

Combined with Aquabio’s AMBR/RO/UV water re-use technology for potable/demineralised applications
AnMBR LETM ANAEROBIC MEMBRANE BIOREACTOR
The AnMBR LETM system combines a low rate completely mixed anaerobic reactor with Aquabio’s proprietary low energy UF membrane separation system. This combination results in a number of advantages in circumstances which favour anaerobic treatment with a focus on very high COD removal rates and biogas recovery. The membrane separation stage provides complete solids retention thus uncoupling the hydraulic and solids retention times allowing for optimised long sludge ages which maximises COD reduction and provides higher biogas yields. The process is more tolerant to TSS and FOG than granular anaerobic systems and thus provides simplified pre-treatment requirements.
