Unused useful matter sewage treatment plant

Sewagewater contains many nutrients that are not or not optimally used.

Waste water consists a lot of cellulose (mostly in form of toilet paper), a valuable raw material with many application. Cellulose is not recovered from waste water as a raw material at this moment.

CADoS is process to recover cellulose from waste water to use it in the de-watering of fermentation sludge. This method of waste water treatment reduces the use of chemicals and energy. Besides this, sludge is discharged with a higher dry matter percentage and therefor less sludge transportation is needed.

• The sieved matter from the de-watered sludge can be converted into bio-gas. But, recycling for the production of bio-plastics is also possible.
• Sludge processing becomes much simpler by using CADoS and certain process parts are unnecessary. Because of this, future sewage plant require less space.
