CADoS technology has gained international attention. Hence discussions has been initiated in the UK and the USA to promote the technology, set up strategic alliances and study particular business cases, with the purpose to generate project leads. Brightwork will be present at the upcoming WEFTEC exhibition (New Orleans, early October 2014) in order to proceed marketing. WEFTEC is the largest annual water quality event in the world.
A project with the world first predicate must also be found in the ‘air’. Therefore, a website is developed about CADoS, which is live since April 11. On this website you can read about the specifics of CADoS, but also about why we start this project. Please read the website and be astonished!
CADoS in a nutshell
The object of the CADoS project is to develop and to build a prototype of the Cellulose Assisted Dewatering of Sludge (CADoS) water treatment concept at the Ulrum sewage-treatment plant. The CADoS principle will be applied to use a new sieving technology innovatively within an existing wastewater treatment process.
Wastewater carried via sewers to the treatment plant contains solid matter that includes a large proportion of cellulose. The cellulose stems from the use of toilet paper. The project will separate the solid matter containing cellulose that is present in the sewage water by means of a fine sieve and will use the separated solid matter for the dewatering of sewage sludge. The CADoS principle is being applied to attempt to reduce significantly the use of chemicals at the treatment plant, to consume less energy and to lower sludge processing costs. CADoS will also increase the energy yield from biogas in the fermentation of sludge.
Water authorities, universities and industry work together in project Cados. The uniqueness of the collaboration is the power of the ‘golden triangle’, and that these parties cover the entire line of water treatment areas. Therefore the effect of theories can be quickly tested in practice. The six parties each have a practical and financial stake in the project, but also each have their own goals and interests.
We regularly publish on this website the latest news around Cados, for example milestones or research findings. In order to stay informed, you can view the page ‘news’. On the webpage ‘publications’ you will find the collection of own and press publications. It is also possible to stay informed via the RSS feed Cados. In order to achieve this you can add the address http://www.cados.nl/en/feed/ to your RSS reader or click ‘rss’ at the bottom of the website.
The website is still very textually inserted. We will soon post pictures supporting the texts.
Questions or more information?
Do you have questions about Cados? You can find under ‘contact’ contact per partner. If you would like more information about the website, please contact Noorderzijlvest Water Authority: Lydia Balkema 0031 50 309 9581
In April and June are symposia where the capture and use of cellulose is central. Cados is from that premise also relevant. You will find per symposium a note below.
From wastewater to new materials
Date: 29 april 2014
Wastewater contains valuable raw materials. What are they? How do you reveal it? Can products be developed with successful market opportunities? These questions play in water authorities and companies in their efforts to recover materials will encourage more sustainable water management and development of new markets.
Several parties – including Noorderzijlvest Water Authority – organize a seminar with workshops for SMEs, where the opportunities to be innovative will be explained.
Toiletpaper from wastewater
Date: 19 june 2014
The recovery of cellulose from waste water is one of the spearheads of the Water Authorities. To achieve this, the Cellulose working group is founded as part of the ‘Raw Materials Factory’. This working group aims to promote the transition from wastewater treatment plant for raw materials in the field of cellulose and eventually closing the chain of cellulose.
In addition to knowledge about the production and valorisation of cellulose from waste water, this symposium has an explicit objective to involve everyone involved in the chain to the subject. Content meets policy, producer meets processor and customer; the wastewater world meets the biobased economy.
