Ammonia Membrane Stripping (AMS™)
Ammonia removal & recovery
Selective membrane for ammonia removal
Applicable NH4 > 500 mg/l
Removal 70 -85%
Product 35 w% Ammonium Sulphate
Quote Christoph EgliGeneral manager wastewater treatment plant Altenrhein (CH):“By introducing the novel Ammonia Membrane Stripping technology in our wastewater treatment plant we can significantly reduce on greenhouse gas emissions.”

DIRECT SEPARATION OF RAW WASTEWATER
o Very clean effluent
o Concentrate
INNOVATIVE TECHNOLOGY
o Pressureless process
o Little membrane fouling
o High concentration factors
o Excellent permeate quality
o Modulair
Forward Osmose as key technology
Pilot test on WWTP Simpelveld [NL]

Raw wastewater
Clean water
Succesful pilot in 2017
PRELIMINARY RESULTS
o Pilot plant 200 l/u
o Concentration factor > 20
o Little fouling and cleaning
o Clean water for discharge
o Concentrate for biogas and nutrients recovery
Preliminary results
STRATEGY
o Development of a sustainable water factory
o The core of the concept is ‘Concentrate’, ‘Recover’ en ‘Reuse (CoRe)’
PLAN
o Direct concentration of raw wastewater
o Co-creation with several innovation partners
o Phase 1 (2018 – 2020): scale up pilot (2 m3/h)
water (re)use
concentrate treatment
o Phase 2 (2020 – 2022): demonstration plant 20 – 50 m3/h
CoRe Water will make the transition possible
