State-of-the-artin municipalwastewater
treatment
§Motivated and guided by environmental legislation and permits
§Most plants owned by community partnerships or cities
§The given goal: to separate and dispose of nutrients, solids, microbes and harmful
substances to meet the permit conditions, with minimum cost
§Community operators have little incentive and minimal funding to develop waste
water treatment from any other point of view
Nutrients and carbon leakage
Large centralized plants,
considerable footprint
Basic ideology and technology
developed in the ’70s
Big investment costs
CO

Efficient treatment and effluents well within standards, however!
Sensitive to fluctuations

A novel approach: non-biological resource
recovery unit based on waste hierarchy principals
1.Advanced physical filtration/separation unit.Chemical/physical advanced filtration using high speed
cross-flow and novel anti-fouling membranes
2.Selective nutrient/resource removal. Evaporative, chemical and electro chemistry based technologies;
N, P, C as pure products
3.Water polishing. Disinfection and filtration to drinking water/irrigation quality
4.Sludge carbonization/chemical routes to products. Thermal and other conversions to fuel, chemicals,
activated carbon, carbon black, and/or soil amendment

Resource Container initiative
§Phase 1 Proof-of-concept for the integrated concept (planned for 2016-2017):
§Concept modelling
§Concept integration and bench-scale laboratory tests and analytics
§Techno-economic pre-feasibility
§Cleantech Finland and Baltic Sea Action Group collaboration
§Phase 2 Piloting / upscale:planned for 2017-2018
Initiative benefits:
-high rate of nutrients and carbon recovery demonstrated
-related cost and potential revenue streams understood
-collaboration initiated with relevant partners and stakeholders
-business opportunities created for cleantech companies
-final target: resource efficiency and lowered emissions to the Baltic sea

Resource recovery has strong drivers
“Second generation phosphorus recovery technologies capable of removing
phosphorus directly from wastewater down to the discharge requirements will be
highly profitable if they can be developed. Ammonium recovery will also be highly
profitable.”
“The world price of ammonium (fixed nitrogen) is increasing rapidly, as is the
world price of phosphorus, so income from selling recovered nitrogen and
phosphorus will increase. The cost of energy to power biological removal of
nitrogen and phosphorus from wastewater, which is the “conventional solution,”
is also rising and the carbon footprint of that energy is a second penalty.”
“Overall, there is an ideal combination of drivers for adopting
recovery technologies that are both reliable and efficient.”

VTT is looking for collaboration partners
We believe the winner concept will be developed as a collaborative effort
using technologies and business thinking from different areas.
VTT is looking for complementing technologies, business owners and
other stakeholders to work with us.
