In those places water quality was also analyzed. We made Physic-chemical and biological analysis (temperature, pH, oxygen, alkalinity and nitrates) where we used macroinvertebrates as indicators of water quality. In general the river has banks with vegetation along almost its entire course, except for in urban areas where it has been partially modified. In these areas we observed water quality changes. We propose recommendations for restoration and conservation of riverbanks.
The effect of nitrate levels on the growth
of Anabaena circinalis • William Tsai An excessive amount of nitrate in wastewater discharged can pose various environmental, economic, and health implications. The aim was to investigate whether nitrates were abundant in effluent discharge from wastewater treatment plants across South-East Queensland, Australia, and subsequent impacts on Anabaena circinalis growth (species that has toxigenic Harmful Algal blooms). Although nitrate levels exceeded guidelines for prevention of eutrophication, however, these levels did not have a significant impact on the growth of Algae. Re-evaluation of regulated nitrate levels may thus be needed. Aqua processor – Integrated water reuse system • Labib Tazwar Rahman, Navid Haider, Sheikh Rifayet Daiyan Srijon The delegation from Bangladesh propose a low-cost, efficient, and user-friendly incorporated recycling system for rainwater and household grey-water (used in sinks, shower and washing purposes) which address the issue of excessive ground water depletion in Dhaka. Through quantitative, qualitative, and economic assessment the research conducted by the delegation yielded that treatment of the two water sources can simultaneously be run in a very small area at t e basement of each urban building to successfully cut down annual groundwater dependence by half.

We have developed, tested, and offered a simple way to use soap economically. These methods are easy to use, envi- ronmentally friendly, cost-effective, and take into account savings in both soap and water. Also, we have developed a biotechnological method of microbial purification using our own detected bacteria and developed biological product based on it. Sharing household and biotechnological methods can significantly reduce the environmental pollution by alkyl sulfates of domestic origin.
Identification of Carbamazepine
Degraders • Nicole Zhao
Carbamazepine (CBZ) is a recalcitrant pollutant that enters natural water systems via human excretion and wastewater treatment plant effluents causing environmental and health concerns. Through a series of isolation and selection pressure experiments using a continuous enrichment system, a microbe found in the Great Lakes basin, Microbacterium oxydans, was found to be capable of degrading CBZ. The use of naturally occurring microorganisms for bioremediation can be a cost-effective and an environmentally-sustainable solution to address CBZ pollution.

Results after cultivation under water stress conditions show that the associated symbiosis enabled lettuce production using less water.
Flash flood prevention system
• Neophytos Fikardou & Evdokia Charalambous
Flash floods are a growing problem for areas with short intense rainfall patterns. Large volumes of surface water carry with them debris that block traditional drains. This project introduces the idea of combining side drain inlets, the process of sedimentation, garbage disposal units, and water triggered sensors to eliminate the problem of blocked storm drains and therefore reduce the risk of flooding. The project includes  a collection of ideas involving a side inlet, a collection box, a water detector and a garbage disposal. The aim is to quickly remove water from the streets in order to prevent floods and more correctly flash floods.
Bubble alarm versus surfactants • Quentin
Meyer, Elodie Leroy & Arthur Boulay
When a water drop falls on the water, we can hear a particular sound. We realized that it is an air bubble vibration that gives this sound. We showed that the vibration frequency depends on the surfactant concentration of the liquid where the bubble is. As the surfactant can do environmental damage, we used our results to develop an innovative method for measuring the surfactant concentration of wastewater. This method is more environmentally friendly than the existing ones, and its playful side contributes to raise awareness to a wide public. Investigating wellwater quality by liquid scintillation counting and potentiometric determination ● Riki Oura I wanted to find out how much radon is present in well water in Kirkkonummi area (40km west from Helsinki), check the quality (fluoride and pH) and find out whether people know the condition of their drinking water. National limits were exceeded in 30 per cent of radon and 20 per cent of fluoride samples. 20 per cent had lower pH than the national limit. Voluntary control of well water does not work well enough in practice since well owners are not aware of the potential health risks. Well water quality checks should be made compulsory or the municipalities should provide the well water quality tests for free.

We have proven the negative characteristics of PET in our experiments. We monitored the journey of water and its treatment in Budapest from the Danube to the consumers and ascertained its excellent quality. We proposed four easily implementable ways to diminish the dumping of used PET into the environment. Georg
Microplastics – A growing problem •
Julia Henrike Freund
In my project I investigated the adsorptive properties of microplastics. Through my experiments I have shown that non-polar substances are indeed firmly adsorbed to plastic in aqueous solution while they are detached in the presence of animal oils. On the practical side I tried to transfer my findings to the filtration of waste water in sewage plants. The aim was to decide whether these interactions can be used to improve the efficiency of filters for a retention of microplastics. I developed a model system and integrated it into the flow process chart of a sewage plant. (GERMANY NATIONAL ORGANISER STIFTUNG JUGEND FORSCHT E. V. SPONSORS • ERNST A. C. LANGE STIFTUNG, BREMEN

We developed a solution based on an oil digesting bacteria and nutrients for treating land oil affected areas and large leaks from tankers. We also designed and built a model of detection and classification system of tankers leaks and of sealing of holes by floating balls in case of small leaks. Preliminary laboratory tests and examination of the method’s cost show a great promise for development of efficient methods of treatment of oil spills and limitation of the damages caused by pollution. Water, chemistry and…. Sclusés! • Tommaso Liut, Arianna Gurisatti & Alessandro Pecile Our project is an environmental study about a beautiful but forgotten area in our region: the Sclusés basin. It is a little lake formed by the confluence of two streams and situated in a very quiet area. We determined the physical and chemical parameters of its water taking monthly measurements for a year; we also identified and catalogued the benthonic organisms, the water-plants, and the vegetation along the banks. The data we collected showed some critical aspects, so we decided to make our results known to the local population and to ask the administrators for some improving actions. To protect our golden spring – A lesson from a Japanese goddess • Mayu Nakagawa, Amauchi Daiju & Yuki Matsui Are you aware of soil's contribution to our environment? We researched how the Goddess of the Earth supports our water circulation. The name of one of our Japanese goddesses is "HAKE".  Acid rain has deteriorated not only lakes, rivers, and groundwater but also forests. The soil of “HAKE” was found to protect the water environment from acid rain by our scientific research. SHE gives us an exceptional Spring in our city (whose Japanese name, "Koganei" means "golden spring"). We insist that we should be aware of the buffering actions of soils and work with HER to protect our environment. 17A1A NATIONAL ORGANISER FEDERAZIONE DELLE ASSOCIAZIONI SCIENTIFICHE E TECNICHE (FAST) SPONSORS • REGIONE LOMBARDIA, FONDAZIONE CARIPLO,AICA, FOIST, LEM WATER SOLUTIONS, ONDAZIONE CRUP ATIONAL ORGANISER JAPAN RIVER ASSOCIATION SPONSORS • LION CORPORATION, CTI ENGINEERING CO.

This project creates a simple treatment to remove fluoride concentrations in underground water and suggests an implementation of an inexpensive and efficient method to quantify fluoride. The study was divided in two stages. Stage one considered experimentation with AC impregnated+ salts. Stage two considered the proposal of an equation to determinate fluoride concentrations. AC + sea salt removed 96.7 per cent; the equations can determinate a wide range of fluoride concentrations.

The aim of the work is to determine and compare the efficiency of various types of wastewater treatment. The conclusion of the research is that the most efficient type of household wastewater treatment for private houses is the treatment with the industrially manufactured biological treatment system with biologically active sludge, which can reduce the concentration of ammonium nitrogen up to 91,9 per cent, which allows to drain the treated wastewater further in the environment.

We have proven that it's possible to generate electrical power combining reverse electro dialysis (RED) with a bipolar membrane and the use of acid, base, and salt. The bipolar membrane transforms H+ (acid) and OH- (base), into water while generat- ing electricity. Solar/wind energy will be reversed into chemical energy, using electro dialysis. When needed, chemical energy is transformed into electri- cal energy, using RED. After this, the concentrated acid and base will be diluted and used again for ED. These liquids don't need to be renewed and they make it possible to store sustainable energy. Midtsjoevann – A sustainable lake? ● Tomine Victoria Hillier & Torbjoerg Venstad Midtsjoevann is a lake, a public swimming area, and a nature reserve close to the city Ski. Therefore, we wanted to examine how surrounding farmers' fields have effected the water quality of Midtsjoevann. We took water samples and analysed them. We were also in contact with a local authority that told us about different initiatives undertaken to ensure the water quality. The results showed us that the water quality changed in relation to the weather and season, and not that much due to the fields. The main reasons were that the topography was very flat and the initiatives from the farmers.
Alternative and sustainable energy source (biomass and biogas) • Abdulmalik Ibrahim Danyar, Shehu Kabir Mustapha & Abubakar Makki Salihu Present work highlights the biomass and biogas from flowers of Calotropis procera . The biomass of flowers that was evaluated for different seasons show a maximum fresh biomass of 799.10 gm in the summer season. The dried biomass of Calotropis procera flowers was subjected to non-polar (petroleum ether 60-80) and polar (methanol) solvent extraction to check its extractibilities. The total extractive yield was found maximum in monsoons, 4.5 per cent (petroleum ether extract) and 27.9 per cent (methanol extract). The flower biomass of Calotropis procera can, therefore, be exploited as a potential source of bioenergy. In this project, the biomass of Calotropis procera and biogas that was produced from solid residues of calotropis procera were used as energy source in thermic power plant due to its high level of organic constituents.

 Phosphate recovery from livestock wastewater using Iron Oxide Nanotubes (INTs) • Min Seok Kim & Kibum Park Hoengseong County of South Korea, where Korean Minjok Leadership Academy is located, is the hub of Korean livestock industries. While Hoengseong is famous for milk production, it is suffering from eutrophication – severe algae bloom – due to influx of livestock wastewater into the water environment. This project aims to prevent cutrophication by developing Iron oxide nanotubes to not only remove phosphate (the main factor of eutrophication) but also to retrieve it for further industrial use. Wastepaper as a low-cost adsorbent for removal of heavy metal ions • Jaron Yu Kit Yong, Daniel Yan Loong Ong & Glen Vintario Heavy metal pollution is a serious environmental concern worldwide. In this study, the ability of wastepaper in adsorbing copper (II), lead (II), and zinc ions was studied. The results show that the maximum adsorption capacities of wastepaper for all the three metal ions were higher than that of activated carbon. When used as filtration media for various types of filter (simple column, ceramic and continuous upflow), wastepaper was able to remove at least 85 per cent, 95 per cent, and 40 per cent of metal ions respectively. Wastepaper has the potential to be used as an adsorbent to purify water polluted with metal ions. ISSIAN for the status.

 Quality of water objects of the State Nenets nature reserve  •  Maria Markova Petroleum products enter the mainstream of Pechora River and Korovinskoe lip (Barents Sea) from the emer- gency well located at Nenets Nature Reserve. The project investigates water quality by bioindication methods and develops recommendations for avoiding oil products transfering to water objects. Wide-spreading of Potametum pectinati community along with Woodiwiss-Yakovlev procedure indices gives evidence of water ecosystems eutrophication. Our recommendations provide an opportunity to take action for dam restoration and to decrease oil product emission into water objects of Nenets Nature Reserve.

To solve the problem, we have designed a simple and accurate model/devise which uses a level sensor and a cell phone to discharge the required amount of water accurately. A cell phone can be used from a distance to open and close the water flow. A person can call cell phone A to open, call cell phone B to close, or setting an alarm for both cell phones in order to open and close at the specific time. SWEDEN The mass balance of Storglaciären • Michael Nyirenda In this report a comprehensive mass balance experiment was conducted on Storglaciären in order to create a model of how global warming could be affecting the Earth's glaciers. The accumulation, ablation, and net value for the year 2014 were calculated by measuring the snow's density and depth. As expected, the net value for Storglaciären this year proved to be negative. Earlier hydraulic measurements conducted on a nearby stream connected to Storglaciären, the Tarfalajäkka, were used in this report to further support the acquired results.

To prevent radioactive substances getting inside the human body through food and drinks you need to have a constant control of potential sources of radiation-polluted water. We have developed and tested a new scientific instrument: it is an overwater robot, a self-propelled platform with radiation-sensible detector and GPS module onboard. The device is capable of creating maps of radiation pollution and performing gamma-ray spectrometry. 

مايهSpecific adsorption capacity of natural/ synthetic materials in separaration of waste oil from water • Mehmet Ikiz & Yunus Emre Bozkurt Today, waste oils are one of the main causes of water pollution and it is an important issue to refine-recycle them. In our project, we aimed to determine the efficacy of the ingredients used for this purpose. We chose particularly waste synthetic adsorbents that can be used in recycling of waste oils. Then, we performed experiments in order to determine the availability of these adsorbents in adsorbtion of domestic waste oils from water.

15 Fish out of thin air • Renatus Groothoff & Sebastian Groothoff Tomorrow's oceans could be void of fish if the fishing industry continues unsustainable harvesting.  While industrial fishing is damaging the ocean ecosystem, aquaculture is also causing ecological harm as 50 per cent of the feed used by fish farms is derived from wild fish. We hypothesised that using photosynthesis and bacterial nitrogen fixation in an aquaponic system we could harvest the four main elements of all biological molecules directly from the air or water turning these into fish protein. Novel renewable filter for heavy metal removal • Perry Alagappan Rapid advances in technology in the 21st century have resulted in the recent and significant rise of electronic waste, which contains highly toxic heavy metals such as mercury, cadmium, and lead. These heavy metals frequently leak into water sources, thus posing a dire threat to us. The problem with existing heavy metal filters is that none of them are readily renewable. Leveraging the power of nanotechnology, a fully regenerable, sustainable, efficient, and first-of-its-kind filter has been created that can remove over 99 per cent of heavy metal contaminants from drinking and industrial wastewater.
