This document discusses resource recovery from water in the Netherlands through the Dutch Top Sector Policy on Water Technology. It provides background on the importance of water to the Netherlands and KWR's role in generating knowledge to help the water sector. KWR works with partners on building knowledge bases, reference projects, products, and networks. Examples of KWR projects focus on recovering resources like water, energy, nutrients, and metals from wastewater and improving processes like biosynthetic production of protein from wastewater gases. The overall goal is developing sustainable solutions for recovering high-value resources and closing resource cycles.

19. Resource recovery from the water cycle
Definition of resources
WATER
Reuse of treated water
ENERGY
Thermal
Chemical: e.g. Biogas from organics
COMPONENTS / ‘by-products’
Organics (PHA, cellulose, etc)
Nutrients (N, P, K, S, Mg, Ca, etc.)
Metals
Drinking water production residuals
(iron oxide, lime, etc.)
55Kees Roest, 10 August 2017
INTEGRAL
e.g. study of resources flows within an airport, city, hospital, etc.

20. Resource recovery from the water cycle
Some TKI Water Technology projects

recovery
• Granular iron for phosphate, arsenic
and H2S binding

21. Value piramide
It is the aim to produce high value products
Kees Roest, 10 August 201757

22. Detection, removal and recovery of metals
From water, sludge and fly ash
The concept
The focus of water treatment is increasingly shifting to
the recovery of raw materials. There might be
opportunities for the recovery of (scarce) heavy metals
and rare earth metals.
Aim
Detection of (rare) metals from the watercycle.
Find a suitable technology to remove and recover the
metals from the water-sewage-sludge-ash-chain.
Testing effectiveness (small-scale) of the chosen
technology

23. CELLULOSE RECOVERYImpact on downstream processes
WwTP Aarle-Rixtel
Capacity: 320,000 PE (150 g TOC/day)
DWF: 2,922 m3/h
FFT: 16,500 m3/h
Finescreen capacity 4,000 m3/h

24. First results
Finescreens
SVI remains 70 -90 ml/l
No negative impact on removal of P & N or on dewatering of sludge
Approximately 12% decrease in m3 aeration (= energy)
Approximately 7% lower sludge production
Increased WWTP capacity (person equivalents) approximately 8%

25. Biosynthesis: Power to Protein
From wastewater to feed/food
The concept
Bacterial protein production from recovered gases at
sewage treatment plant.
Protein in feed or food.
Aim
Sufficient food, reduced environmental impact
