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.

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.         

Eutrophication has many effects  algae blooming  phosphorous-depending cyanobacteria  dead bottoms and hydrogen sulphide

(1) Nitrogen is emitted to waters

(7) Summer blooming of cyanobacteria

(2) Spring blooming of plankton

(6) Phosphorous is released

(3) Algae die (4) Algae are decomposed which consumes oxygen (5) Bottoms get anoxic

Extent of oxygen-depleted bottom water In the Baltic Sea

Worldwide

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 selfcleaning biogeochemical processes?

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!

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

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

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

Results (so far)? ď&#x201A;§

Lifecycle Assessment (LCA) and Lifecycle Cost (LCC) analyses indicates that the WEBAP is the most sustainable and cost-efficient alternative

Wastewater treatment intelligence The need for R&D facilities to master the future

Background 

> 2 billion people have water shortage



Diseases due to bad water quality



Millions lack proper waste-water treatment



Deterioration of quantity and quality of natural water systems



Agriculture uses 2/3 of the water that is consumed

  

Increasing water demand for industrial growth New regulations (e.g. EU) Use of chemicals in water treatment  <1% recycling



Request of use of renewable energy sources



Sustainable growth and development
