TECHNOLOGY
AMBR LETM - AEROBIC MEMBRANE BIOREACTOR
Next generation low energy MBR technology
AEROBIC MEMBRANE BIOREACTORS
Aquabio’s aerobic membrane bioreactors are the most compact and cost-effective MBR systems available. The process combines aerobic biological treatment using jet/slot aeration technology with tubular crossflow ultrafiltration (UF) membranes for biomass separation to deliver superior quality treated water which can be applied directly to RO/UV technology to allow water re-use. The aeration and membrane systems are mounted outside of the tank to provide hygienic operation with a focus on the safety and ease of maintenance.

Nutrient removal, nitrification and denitrification
Combined with Aquabio’s RO/UV water re-use technology for potable/demineralised applications
AMBRTM AEROBIC MEMBRANE BIOREACTOR
Aquabio’s AMBR LETM system is optimised to provide low energy use, compared with conventional crossflow or submerged membrane separation systems. By employing intermittent back flushing of membranes, fouling is controlled, enabling a reduction in crossflow velocity and a significant saving in energy. Variable speed recirculation pumps provide a variable flux rate that is used to optimise energy use relative to the plant throughput. Plants remain very compact, with low membrane area and optimal membrane replacement costs. The cross flow ultrafiltration (UF) membranes provide a complete barrier to suspended solids resulting in a high quality, solids free permeate which can either be sent as a low cost discharge to sewer or water course or ideally applied directly to Aquabio’s RO/UV technology to provide potable water re-use.
