DEMOWARE

"Innovation Demonstration for a Competitive and Innovative European Water Reuse Sector"

Funder(s):
  European Commission (Seventh Framework Programme for research, technological development and demonstration under grant agreement no 619040.)
Timescale: 
  Jan 2014- Dec 2016
     
  The DEMOWARE project has as a primary ambition to deliver a European roadmap for a viable water reuse industry through providing business cases for the development of water recycling projects, which will pave the way for future opportunities. The project brings 27 institutions from ten different countries together, including public authorities, regulators, water utilities and companies, the research community and the public, to generate and share knowledge on innovative water reuse schemes technologies, not only to increase water use efficiency, but to position Europe ahead of the world market for water reuse. The project is guided by SME & industry priorities and has two central ambitions; to enhance the availability and reliability of innovative water reuse solutions, and to create a unified professional identity for the European Water Reuse sector. The project focuses on the specific opportunities and benefits of water reuse in each of the three main water sectors: agriculture, industry and urban as well as on the interfaces between each of these sectors. The project seeks to overcome constraints including technological, economic and social barriers.

 

Using nine existing and one greenfield innovation demonstration sites distributed all over Europe and Israel, the project aims to improve both operator and public confidence in reuse schemes by:

  • deepening the evidence base around innovative treatment processes performance and reuse schemes,
  • testing new tools for process monitoring and performance control,
  • providing strategies for the risk management and quantifying the environmental benefit of water reuse.
  • advancing the quality and usefulness of business models and pricing strategies,
  • generating regulatory regime specific guidance on appropriate governance, public involvement and stakeholder collaboration processes and,
  • the establishment of a European water reuse association to shape market opportunities for European solution providers.

Ultimately, the DEMOWARE outcomes will increase Europe’s ability to profit from the resource security and economic benefits of water reuse schemes without compromising human health and environmental integrity.For more information, please visit the project website at: http://demoware.eu/en


ANSWER/H2020-MSCA-ITN-2015/675530

"Antibiotics and mobile resistance elements in wastewater reuse applications: risks and innovative solutions".

Funder(s):
  European Commision (H2020)
Grant Holder:
  Nireas-International Water Research Center, University of Cyprus
Timescale: 
  Oct 2015 - Sept 2019
 

 

 

The main objective of ANSWER/H2020-MSCA-ITN-2015/675530 is to develop well-trained and creative Early-Stage Researchers (15 ESRs) through innovative PhD projects to reveal the highly complex factors driving antibiotics and antibiotic-resistant bacteria and antibiotic resistance genes (A&ARB&ARGs) propagation in the framework of urban wastewater reuse.

ANSWER is developing knowledge and further understanding of the reuse practice, with the aim to reduce environmental and possible public health risks and identify opportunities for establishing safe reuse systems. ANSWER aims at answering critical questions related to wastewater reuse, and in particular to provide consolidated insight on the potential effects of the reuse practice with regard to antibiotic resistance. The pioneer leadership of Europe in the field of contaminants of emerging concern in the environment, will be sustained through ANSWER, whose benefits will be of scientific, technological, economical and of course societal character and significance. The European society has many to gain from ANSWER, including contributions towards clean environment and health protection.

ANSWER intends to result in a long-lasting network for future cooperation between the involved institutions, creating a training platform that will continue in the future, having a strong impact both on the scientific community and on the careers of the ESRs.

The network consists of 10 beneficiaries and 8 partners, from 9 countries (Austria, Cyprus, Germany, Israel, Italy, Portugal, Slovakia, Spain, and the Netherlands). ANSWER is coordinated by Dr. D. Fatta-Kassinos (Nireas-International Water Research Center, University of Cyprus) and is organized into 5 Technical Working Packages (WPs) with the following objectives:

ECWRTI

"Total Water recyling in water industry"

Funder(s):
  European commision (Horizon 2020 programme - EU.3.5.4, Project reference: 642494)
Timescale: 
  June 2015 - Dec 2018
     

A new technology for the treatment of wastewater from the textile industry, EcoloRO, will be tested at full scale in Belgium from June 2015. The technology uses electrocoagulation combined with membrane filtration. The electrocoagulation stage is able to remove 93 to 96% of the pigments/dyes from wastewater produced by textile mills while the membrane filtration stages (Ultrafiltration/Reverse osmosis) further purify the water for reuse, hence providing an opportunity for textile companies to reduce their fresh water consumption by up to 90%.

A selection of recent insights from published research

 

Theme: Regulations
Common or independent? The debate over regulations and standards for water reuse in Europe
Fawell, J., Le Corre, K., Jeffrey, P.

 

Abstract: Although unplanned water reuse has been practised across Europe for decades, multiple stresses on water supply and demand over recent years have led to the development of many planned reuse schemes. Despite this development, the legislative and regulatory regimes required to underpin a growing water reuse sector have arguably failed to emerge. The reasons for this and the cases for and against pan-European water reuse regulations are explored and debated. The conclusions highlight several challenges for politicians and policy makers if appropriate regulatory systems and water quality standards are to be provided which support the embryonic European water reuse sector.

Removal of phages and viral pathogens in a full-scale MBR: Implications for wastewater reuse and potable water
Purnell, S., Ebdon, J., Buck, A. Tupper, M., Taylor, H.

 

In this article, the authors investigate “how seasonal variability in the removal efficacy of enteric viral pathogens from an MBR-based water recycling system might affect risks to human health if the treated product were to be used for the augmentation of potable water supplies”. The authors conclude that based on the outcomes of their experimental work “membrane bioreactor technology appears to have considerable potential to protect human health in wastewater reuse systems, potentially including the augmentation of potable water supplies” although “further investigation are needed to ascertain the infectivity of viral particles to determine whether the presence of viral pathogens in chlorinated product presents a real risk to human health.”

Abstract: The aim of this study was to demonstrate how seasonal variability in the removal efficacy of enteric viral pathogens from an MBR-based water recycling system might affect risks to human health if the treated product were to be used for the augmentation of potable water supplies. Samples were taken over a twelve month period (March 2014–February 2015), from nine locations throughout a water recycling plant situated in East London and tested for faecal indicator bacteria (thermotolerant coliforms, intestinal enterococci n = 108), phages (somatic coliphage, F-specific RNA phage and Bacteroides phage (GB-124) n = 108), pathogenic viruses (adenovirus, hepatitis A, norovirus GI/GII n = 48) and a range of physico-chemical parameters (suspended solids, DO, BOD, COD). Thermotolerant coliforms and intestinal enterococci were removed effectively by the water recycling plant throughout the study period. Significant mean log reductions of 3.9–5.6 were also observed for all three phage groups monitored. Concentrations of bacteria and phages did not vary significantly according to season (P < 0.05; Kruskal-Wallis), though recorded levels of norovirus (GI) were significantly higher during autumn/winter months (P = 0.027; Kruskal-Wallis). Log reduction values for norovirus and adenovirus following MBR treatment were 2.3 and 4.4, respectively. However, both adenovirus and norovirus were detected at low levels (2000 and 3240 gene copies/L, respectively) post chlorination in single samples. Whilst phage concentrations did correlate with viral pathogens, the results of this study suggest that phages may not be suitable surrogates, as viral pathogen concentrations varied to a greater degree seasonally than did the phage indicators and were detected on a number of occasions on which phages were not detected (false negative sample results).
