2. IVL Swedish Environmental Research Institute is an independent, non-profit research institute,
owned by a foundation jointly established by the Swedish Government and Swedish industry.
IVL Swedish Environmental Research Institute was established in 1966 and has since then been
involved in the development of solutions to environmental problems, at national and
international level.
We work with applied research and contract assignments for an ecologically, economically, and
socially sustainable growth within business and society at large. The institute employs around 200
experts, which makes IVL a leading institute for applied environmental research and consultancy
services.
3. Collaborations
We are members of a number of national and international networks.
We also have close collaboration with universities. Through these connections, we have access to
unique knowledge and highly qualified partners.

7. Eutrophication has many effects
algae blooming
phosphorous-depending cyanobacteria
dead bottoms and hydrogen sulphide
(1)
Nitrogen is
emitted to waters
(2)
Spring blooming
of plankton
(3)
Algae die
(4)
Algae are de-
composed which
consumes oxygen
(5)
Bottoms get
anoxic
(6)
Phosphorous
is released
(7)
Summer blooming of
cyanobacteria
9. Need for action?
Doesn’t the Baltic take care of itself?
How affects and is the Baltic affected by climate change?
Can technical solutions help in a long term?
Why do we think we need actions also in the Baltic and not only at sources?
There sure is a good monitoring of sources and these sources can be abated?
The Baltic in imbalance? Weakening of natural processes? Restore the Baltic Sea self-
cleaning biogeochemical processes?
10. WEBAP: Aim
Improved oxygen situation in deep water layers
Species that are dependent on conditions in deep water, would get a better
environment and opportunities for reproduction.
Solved inorganic phosphorus released due to the reducing conditions in the bottom
sediments will be bound in complexes and thus reduce the inorganic nutrient
concentrations in the water.
Yet:
2-6 million tons of oxygen needed each year!
Enormous amounts of energy to pump oxygen down to 80-120m depth!
11. WEBAP: How?
The use of natural resources:
Source of energy: waves
Source of oxygen: oxygen-rich surface water
Advantages:
Oxygenation & mixing
Simple and robust design with no moving parts
No need for electricity
12. WEBAP: Planning and design
18 tests with different wave conditions
mooring forces
Pump capacity for each wave spectra
Stability
Optimal ramp (30˚isoptimal)
other details
13. WEBAP: Pilot I
Facts
14 m with, variable ramp
faces waves at all conditions
outlet at 75m depth
Measurements
Pump-capacity, wave parameter, currents,
CTD-profiles, sediment, forces, stability, behaviour, etc.
Operation period
November 2010 to April 2013 (with interrupted operation
between December 2010 to July 2011)
14. WEBAP: Pilot II
Facts
2,5 m in diameter, variable pump-capacity between 1-4m3/s
maximal effect use 5 kW
outlet at 100m depth
Measurements
Pump capacity, CTD-profiles, sediments,
metals, nutrients, currents etc.
Operation period
April 2011 to September 2012
15. WEBAP: Monitoring
Online monitoring
Field expeditions
Water and sediment samples
Historical data
17. Results (so far)?
Measurements and mapping of the lack of oxygen in the
area indicate that the lack of oxygen in the pilot areas is
more widely spread than previously estimated
Measurements confirm the estimated
pumping capacity at different wave heights
Large scale implementation modeling
establishing that the technique does not
affect the salinity stratification
Modeling for the Gotland Deep based on
field data show oxygenation of the whole
area down to the seafloor after only five years
18. Results (so far)?
Tests with sediment and organisms from the pilot
sites show no adverse effects of oxygenation
Potential to bind up to 100 000 tones of phosphorus,
which can be compared with the annual land supply
of around 30 000 tones /yr and the environmental
objective to reduce this load by 15 000 tones /yr
Several setups for different conditions (waves, etc.)
Modeling of pumping in Kanholmsfjärden based on
field data shows effect of oxygenation not only in
Kanholmsfjärden but also in adjacent bays due to the
high water exchange
19. Results (so far)?
Lifecycle Assessment (LCA) and Lifecycle Cost (LCC)
analyses indicates that the WEBAP is the most sustainable
and cost-efficient alternative
20. Dissemination an awareness increase
Newspaper, conferences, TV, notice
boards, homepage, Facebook, reports, exhibition, flyer, seminars, radio, etc.
