The Koningshoeven BioMakery is a biological
wastewater treatment system based on modular
and functional reactor- based ecological
engineering.
Based upon the principle of water-based urban circularity,
where energy, food, and waste systems are built around
a regenerative and sustainablewater cycle.
Powered by Metabolic Network Reactor (MNR)
technology, which uses 2-3,000 different species of
organisms ranging from bacteria to higher level
organismssuchas plants.

1. Objectives of the NextGen solutions
Combine Metabolic Network Reactor (MNR) and membranes
for nutrient and water recovery for fit-for-use industrial use
such as irrigation, bottlewashing or make up water for beer
production
Use “Bio-makery” for water reuse in decentralized areas
Carbon, nitrogen and phosphorus recovery, with nutrients
removed from the water converted into fertilizer used to
produce plant or microbial protein

Note: The MNR on the brewery line demonstrated the ability to reduce most important water quality parameters
below discharge limits under stable influent conditions. However, due to a highly variable influent and operational
difficulties stemming from Covid19, the system is not yet stable and does not meet the discharge limits consistently.
MNR has ability to reduce most important water quality
parameters, but is sensitive to fluctuations in brewery

5. Lessons learned
Closer interaction with brewery needed.
Due to decentralized character highly reliant on too few operators
Combination with remotely controlled physicochemical treatment
provides redundancy
Interesting solution that offers opportunity for high-value added product
recovery, but requires large surface area
Fluctuations may affect quality of biomass
Operation by highly skilled operators crucial (PD and MSc students)

2. Lessons learned – new solutions
Local solution to COVID challenges
Collaboration started with Jotem waterbehandeling B.V.
Construction of WTUB inspired systems on-going
• Scenario 1: Brewery effluent
• Scenario 2: Municipal effluent
• Both scenarios: reuse quality of permeate (QMRA and
QCRA) and concentrate quality for purple bacteria
Task 1.2.6 Production of fit-for-purpose water in La Trappe
(Pilot)
Installation of remotely controlled pilot (capillary NF 400/800 Da) for fit-for-purpose
water 100-150 l/h after MNR from December 1st, 2020
