H20 as Fuel
By Ramiro Hernan Olivera Fedi, Alan Milton Patricio& Camila Micaela Rodriguez
The delegation from Argentina developed an innovative method to
reduce pollution from vehicles. The team has invented a new solutionthat will enable a car engine to run on water. They use an electric
current to break the water molecules down into hydrogen and oxygengases, which are then injected into an internal combustion engine.
This improves performance, lowers the emissions of pollutants andreduces the consumption of fossil fuels.

Polymer Power: The Extraction of Divalent Heavy
Metal Ions from Aqueous Solutions Using Sodium
Polyacrylate to Treat Contaminated Waterways
By I-Ji Jung
Heavy metal contamination of waterways is a serious problem
that can lead to both environmental and human health problems.
The Australian project investigated the inadequate treatment ofwastewater and how this affects the heavy metal contamination ofwaterways. The conventional method utilised in heavy metal treatment is often very expensive and requires an extensive amount ofenergy. The Australian delegate discovered that sodium polyacrylate,a super- absorbent polymer, could be used as a more effective andeconomical alternative treatment method to revitalise waterways
around the world.

Bioassay as a Mode of Wastewater Control
By Aleksandra Kirilchik
The Belarusian project demonstrates how the usage of bioassay is thebest method of wastewater control. By using a culture of freshwater
crustaceans – Daphnia Magna (Strauss) – that are sensible to low
concentrations of toxic substances, the Belarusian team found several
points of toxic pollution in the main river of Minsk – the Svisloch
River. The technique of using bioassay was also successfully applied
at a local wastewater treatment station, which is situated at the shoreof the biggest lake in Belarus – Naroch Lake.

Multi-Walled Carbon Nanotubes Bioremediation
By Arnaud Desrosiers
In 2011, 10 million tons of carbon nanotubes (CNT ) were produced
while there was not any process made to degrade them effectively.
CNT are nanoparticles that are easily spread in water and transport
pollutants. This project tested the capacity of hemin and several
bacteria to degrade multi-walled carbon nanotubes (MWCNT ) by
exposing the MWCNT to seven bacterial cultures and one hemin
solution. While the bacteria were unable to degrade the MWCNT,
the hemin solution showed strong potential with an average degradation rate of 14.6 per cent over 7 days. These results open possibilities
for a degradation process of MWCNT on large scale applications,
including wastewater or industrial waste treatment.

Chilean Salmon: Sustainable Car Food
– Reducing Seawater Pollution Through the Use of
Aquaculture Industry Waste
By Alonso Alvarez & Daniel Barrientos
Chile is the world’s second-largest exporter of marine resources, but
the fishing industry is beset by complex social and environmental
challenges. Following preliminary studies that helped rule out
other fish, the Chilean team investigated how salmon waste, thatwas otherwise unsellable, could be used for biofuel production andbring added value to the industry. Their project showed that, in
addition to cutting down on seafloor pollution and ensiling costs,
salmon oil could produce enough biodiesel to fuel 78 vehicles over
100 km a day.

How to Increase Dissolved Oxygen in a Stream– Determining Oxygen Concentration of Finnoonoja
with the Winkler Titration
By Pihla Ruohonen
In order to maintain a healthy aquatic community, the concentrationof dissolved oxygen in the water should be above 6 ppm. One way
to increase oxygen is by adding rocks and gravel to a river bottom,
which was done in a stream in Espoo. The Winkler method wasused to analyse samples collected from both treated and untreatedparts of the stream to see if reconditioning has a positive effect on
the dissolved oxygen. It did not seem to have a significant effect,
but another possible solution was found.

Surface Oxygenation of Water Bodies by Solar-Wind
Oxygen Mill – Case Study of Polemidia Water Dam
By Mario Christou, Georgios Menelaou & Andreas Ttofi
Water pollution, eutrophication and related causes of anoxic conditions are among the most serious problems related to water bodies.
Aeration is required to eliminate these anoxic conditions. The teamfrom Cyprus endeavored to build and test a new kind of aeratingmachine. The invention utilises green energy, solar and wind power,
and introduces oxygen into the surface of the water in order toincrease the water body’s oxygen level.

Acting Simply or Utilizing Green Seaweeds
By Pauline Cazeneuve, Nolvenn Gomez & Pierre Ollivier
Ulvea is a type of seaweed that generates toxic gases when it dries.
Ulvea can accumulate in holes in the sand on beaches, and emit
poisonous gas within three days. The French delegation has aspired
to find a use for the ulvea as an organic fertiliser for local farmers.
By collecting the ulvea from the ocean while it is still fresh and thenquickly dehydrating it, the release of toxic gases can be avoided. This
innovative yet simple process makes productive use of the seaweedthat is safer for people and better for the environment.

Greywater Recycling System for Toilet Flushingin PRESECBy Derrick-Brown Akolbire & Kwabena Owusu Boateng
In this study, the potential of using grey water generated from thebathroom and laundry to flush toilets in a dormitory of a local seniorhigh school was assessed. Grey water collected from wastewateroutlets is treated in a four step process in order to eliminate contaminants and making it suitable for non-contact use. The system
was capable of removing bacteria, odor and almost 90 per cent of
the turbidity in grey water, making it a suitable alternative to obtainwater for non-contact use, such as flushing toilets.

Smart Heater: A Device for Controlling Conventionaland Solar Domestic Water Heaters and Increasing
Their Efficiency
By David Rafael Agassi & Bashan Yehezkel
Though alternative energy sources are promoted, they are not
perfected. In solar and non-solar water heaters today, there is no
system for measuring water temperatures in the heater and using
this information. As a result, considerable amounts of water andenergy are wasted. The Israeli delegation has invented a system thatprovides this missing information and that prevents the waste ofwater and energy.

Fluoride in Drinking Water? Past History!
By Arianna Broggi & Lara Nonis
The presence of fluoride in drinking water is a serious problem inless developed areas of the world, where the technological methods
used for years in affluent areas are not applicable. The Italian teaminvestigated new low-cost methods for the removal of fluoride, usingmaterials that were available but not used in less developed areas.
After a lengthy trial, they found that eggshells and Spirogyra (a formof freshwater algae) can effectively remove fluorides.

Soil Rehabilitation by Using Micro Bubbles
By Ai Hemmi, Ami Hizawa & Kazuma Komachi
In March of 2011, a 9.0-magnitude earthquake hit Japan. A large
tsunami followed and left 21,476 acres of salt affected farmland
behind. The Japanese team sought to find an effective way todesalinate land by using water which contains more than 1 million
micro bubbles in 1 cc. The experiments suggest that micro-bubble
water leaches out salt more efficiently than ordinary water. Using
water with micro bubbles to desalinate also uses less water, which
is beneficial to water conservation.

Desalination for a Better Life – Converting Seawater
into Fresh Water
By Jolet Mimpen & Annelisa Cornel
The Dutch delegation sought to create a solution that could be used
to desalinate water in developing countries that is easy to implement,does not require electricity and can be executed using locally available resources. They designed a glass house with two tanks, one forseawater and one for freshwater. Through the evaporation of the sea
water, freshwater will eventually fall into the second smaller tank,which has a small opening to slow evaporation once the freshwater
is stored within it. The salt removed from the seawater can be thentaken out and used, or can be sold in local markets.

Developing a Device for Water Reservoir Monitoring
By Kirill Ilin & Denis Merkulov
There is no current routine in place to monitor small water bodies
in Moscow, despite the fact that they have exceptionally highvalue to society. The Russian delegates designed and field tested anautonomous automatic laboratory (AAL) on two small reservoirs in
Moscow, where they conducted an environmental assessment andfollow up plan to maintain the health of the water bodies. They also
designed two devices to monitor water in the reservoirs – a small
radio-controlled speed boat and a PC tablet, NOVA 5000. Using theseinventions, they were able to collect primary water quality data
easily, quickly and accurately, which they believe can be used to enableeffective research planning on small water bodies on a wider scale.

Isolation of Microorganism from the Environment
Able to Degrade Selected Pharmaceuticals
By Kristina Hanusová & Michal Radó
Human pharmaceutical compounds are emerging environmental
contaminants that have become a growing concern in recent years.
Metabolised or original pharmaceuticals are often not eliminatedin wastewater treatment plants, and consequently they enter surface
waters. Taking the above into account, the main objective of thisproject was to isolate the microorganisms from the natural waters,
which are affected by municipal wastewater – preferably directlyfrom the recipient.

Crustaceans of the Black Sea as Biomarkers of Heavy
Metal Pollution
By Andriy Andrusyshyn
Anthropogenic pressure has become a serious threat to both sea
biodiversity and human health all over the world. This threat isaggravated by the ability of certain compounds, such as heavy metals, to accumulate at all levels of the ecological pyramid. It is wellknown that crustaceans play an important role in the destructionof organic matter and the functioning of the sea biocoenosis. The
Ukrainian project suggests that crustaceans can be used as biomarkers of seawater pollution and explains how this would help us better
monitor and maintain ecosystem health in the sea.

The Foundations of Aquatic Biodiversity
By Sam Cook
Photosynthetic microorganisms constitute the basis of aquatic biodiversity; they are invisible to the naked eye, but very importantto their habitat. Diatoms, a key component of this biodiversity, are
an indicator of water quality and ecosystem health. This project
developed a new classification system for Diatoms and for the firsttime explored their value in wetland aquatic ecosystems, which isfundamental to environmental and river basin management.

Modeling and Environmental Analysis of HydraulicFracturing in Upstate New YorkBy Kunal Sangani
The development of hydraulic fracturing, or “hydrofracking,” hasmade natural gas stored in shale rock accessible. However, environmentalists fear the process may contaminate shallow water aquifers.
The US project has investigated these concerns by developing amathematical model for the process and testing the toxicity of hydrofracking wastewater. The US delegate found that lower fracturing
pressures can be used to mitigate the effects of hydrofracking onwater supplies while producing equivalent amounts of natural gas.
