Nereda® Aerobic Granular Biomass

Nereda® Aerobic Granular Biomass

  • Sustainable Technology
  • Significantly Smaller Footprint than Conventional Plants
  • Reduced Energy Input (25 - 35%)

 

Description

Aerobic Granular Sludge (AGS)

This unique technology is supported by Aquatec Maxcon, Australia’s leading water technology provider and the leading European technology developer and consultant, Royal HaskoningDHV. 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 concentrates naturally in compact granules, with excellent settling properties. As a result of the large variety of biological processes that simultaneously take 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.

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.

The continued success of Nereda® technology has meant that currently larger plants are being designed and built including a 2,400,000EP plant in Dublin and a 500,000EP plant in Utrecht. There are more than 16 plants operational worldwide, including Kingaroy WWTP in Australia. Kingaroy WWTP is a 12,500EP Nereda® Plant that was commissioned in May 2016 and to date has achieved exemplary effluent results.

Advantages of Nereda®

Cost Effective

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 operations and maintenance 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 while producing a remarkably high effluent quality. The technology requires less waste generating chemicals, construction materials and mechanical equipment for an overall reduced carbon footprint.

Technical

With the distinctive characteristics of granular biomass, Nereda® technology uses an optimised SBR cycle:

  • Filling of influent and simultaneous displacement of purified water.
  • Aeration results in extensive simultaneous biological removal of organic, nitrogen and phosphorous compounds.
  • Biomass is separated from the purified water during a very short settling phase and Nereda® is ready for a new cycle.
  • Aerobic, anoxic and anaerobic biological processes take place simultaneously in the granular biomass and optimal biological treatment is accomplished in only one effective aeration step.
