Nereda® Aerobic Granular Biomass

Nereda® Aerobic Granular Biomass

  • Nereda biomass (left) and activated sludge (right) after only 5 minutes of settling

    The Next Generation in Sewage Treatment

  • Significantly Smaller Footprint than Conventional Plants

  • Reduced Energy Input (25 - 35%)

This unique technology is supported by Aquatec Maxcon, Australia's leading water technology provider and the leading European technology developer and consultant, DHV.

Nereda® is an innovative, advanced biological wastewater treatment technology that purifies water using the unique features of aerobic granular biomass. Unlike conventional processes, the purifying bacteria concentrate naturally in compact granules, with excellent settling properties. As a result of the large variety of biological processes that simultaneously takes place in the granular biomass, Nereda® is capable of meeting stringent effluent quality requirements. Extensive biological phosphorus and nitrogen reduction is an intrinsic attribute of this technology, resulting in chemical free operation.

Breakthrough technology based on aerobic granular biomass

These unique process features translate into compact, energy saving and easy to operate Nereda® installations for both municipal and industrial waste water treatment. Nereda® presents attractive new solutions for greenfield and brownfield sites and retrofitting or extending conventional activated sludge plants. The technology is also highly recommended for performance and capacity upgrades of existing SBR facilities. 

Advantages of Nereda®

Cost Effective

Nereda treating municipal waste water

Nereda® enables extensive biological treatment in a compact and simple design.

Reduced plant costs are achieved through:

  • High energy efficiency of the process
  • Less mechanical equipment than conventional processes
  • Concentrated biomass, reducing tank volume
  • Reduced direct plant costs
  • Reduced O&M costs

Easy to Operate

Plant operation is easy and process performance is robust. The Nereda® system is fully automated ensuring reliable performance and ease of operation. 

Sustainable

Extensive life cycle analyses reveal Nereda® as a truly sustainable technology. Compared to conventional processes, Nereda® has significantly lower energy consumption but also produces a remarkably high effluent quality. The technology requires less waste generating chemicals, construction material and mechanical equipment for an overall reduced carbon footprint.
