Nereda promises “water industry step change”

Technical expert at RoyalHaskoningDHV, Andrew Thompson explains: “Nereda® is rapidly becoming the new standard to replace traditional activated sludge processes, with an installed base to exceed five million population equivalent by the end of 2017.


Utilising granular technology, Nereda® has demonstrated significant improvements with regard to process stability, effluent quality (Ammonia<1mg/l, TN<5mg/l, TP<0.3mg/l), and energy savings of 30-50% compared to traditional processes.” This is set to introduce a step change in the water industry, says Thompson.

With over 30 plants in operation and under construction around the world and the first UK Nereda plant due to come into service in 2016 – along with others in the design and construction stage – there is already a high level of interest in the benefits this new technology can provide. A presentation at Aqua Enviro’s European Waste Water Management Conference provides a platform to share the current performance of the technology both in the UK and further afield. The accompanying paper being presented in October will explore in more detail how Nereda® technology can be combined with other technologies such as advanced anaerobic sludge digestion, to create wastewater treatment works that generate more energy than required for treatment. It also examines the opportunity for the addition of resource recovery technology, such as struvite and alginate recovery, to create the possibility of developing profitable wastewater treatment.

The presentation and technical paper: ‘Nereda® – an innovative technology for cost-effective, energy efficient, sustainable and profitable wastewater treatment’, will be delivered at Aqua Enviro’s European Waste Water Management Conference, 11 – 12 October 2016 at Manchester Town Hall.
