Working with our water company customers, we would be really interested in developing a paper, numerous papers or running a whole session on Royal HaskoningDHV’s Nereda technology and its impact on the UK water industry and beyond. Below you will find a summary of the subject areas we could cover.
Introduction
Nereda is a wastewater treatment technology that purifies water using the unique features of aerobic granular biomass. Nereda is sustainable and cost-effective: it requires a quarter of the area of conventional activated sludge installations and the process can reduce up to 50% on energy-costs. The award-winning technology was invented by the Delft University of Technology in the Netherlands and developed in a unique public-private partnership between the University, the Dutch Foundation for Applied Water Research (STOWA), the Dutch Water Authorities and Royal HaskoningDHV.
Abstract one: Nereda technology worldwide
This paper would provide an overview of the development of Nereda technology and its application worldwide to date. Since the original installation of Nereda technology at Vika Food Ingredients in The Netherlands in 2005, our technology has come a long way. We now have over 40 reference projects across five continents, and this number continues to grow. One of our latest projects is Ringsend in Dublin, which when complete will have the capacity to treat wastewater for 2,670,000 people equivalents.
Abstract two: Why Nereda?
Water companies face many challenges and Nereda technology has been designed to address many of these. This paper looks at the benefits of the technology from its compact design and small footprint, and producing high quality effluent, through to it leading the field in P recovery and alginate production.
Abstract three: How low can we go?
Nereda technology has recently been used successfully in pilot trials at two UK sites – Macclesfield and Newmarket. This would potentially be a joint paper with Anglian Water and United Utilities to present the P removal pilot trial data.
Abstract four: Why United Utilities selected Nereda technology
This would be a joint paper with United Utilities highlighting United Utilities’ research into Nereda technology and the results that lead to the decision to build Nereda plants at four sites so far. This includes Blackburn, which when complete will be the largest purpose-built Nereda plant in Europe to date.
Abstract five: At what cost?
Scottish Water has recently carried out feasibility studies for a new 15,000 PE works in Winchburgh. This paper looks at the results from the feasibility study and the totex costs for Nereda.
Abstract six: Performance results
The Nereda plant at Thames Water’s Highworth wastewater treatment works is the first full-scale Nereda plant in the UK. This paper explores the initial performance results from this plant.
Abstract seven: PPS2 at Ringsend
The development of the Ringsend plant in Dublin, Ireland demonstrates the adaptability of Nereda technology and how it can be used as an innovative solution, particularly where footprint is limited. When complete, Ringsend will have the capacity to treat wastewater for 2,670,000 people equivalents.
Abstract eight: Biowin modelling
Modelling is a vital tool for designers. Biowin modelling offers a new model that we can simulate Nereda with. This paper looks at the capabilities and limitations of the computer modelling package.
