Modular, sustainable WWTPHow to supply clean effluent for horticulture and industry
Determine the possibilities of matching water
demand and supply in two case-study areas in
Limburg
Saves costs and energy when a WWTP needs
large-scale renovation or replacement, or when a
new plant is to be built

Aim: counteract salinization of water wells
Concept: (1) intercept (pump) intruding brackish water;
(2A) dispose brackish water (deep well injection) or (2B)
use it as additional freshwater source after BWRO
Projects:
- Full scale pilots (2x) at Vitens, Noardburgum

Calorics
Goal
Study the technical and financial feasibility of
measures to retain a climate-proof distribution
network.
Measures may be needed to prevent unwanted
warming and aftergrowth in the distribution network
due by climate changes.
Recycling of thermal energy with the use of ATES
(Aquifer Thermal Energy Storage).

Bring the resource to the recoveryNew sewage concepts
Aim: concentrate sewage, smaller sewage system
• Disconnect household water from drainage
• More water efficient toilets
• Organic kitchen waste into the sewer
Toward smaller diameters
• Inclination angle is the determining factor, not the diameter
I.a. researching clogging:

Granular iron (hydr)oxide from iron sludgeAdding value to an existing by-product
• Strength of iron sludge: binding ofP, As and S
• Weakness: low permeability, highcontent of water
Opportunities :
There is a market for bindingphosphate in surface water, arsenicremoval for drinking water productionand preventing odour from biogasinstallations
Challenge:
Is it possible to produce granular iron(hydr)oxide with good mechanicalcharacteristics, constant quality andaffinity for P, As and S?
