4ARiverbanks and water quality in theriver Chimehuin • Walter Eduardo Aigo, Patricio
Martín Arce & Joaquín Antú Porma
Riverbank samplings were carried out throughvegetation transects on five sites of the river
Chimehuin from its source to near the mouth.
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 ofwater quality. In general the river has banks withvegetation along almost its entire course, except forin urban areas where it has been partially modified.
In these areas we observed water quality changes.
We propose recommendations for restoration andconservation of riverbanks.

The effect of nitrate levels on the growthof Anabaena circinalis • William TsaiAn 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, theselevels did not have a significant impact on thegrowth of Algae. Re-evaluation of regulated
nitrate levels may thus be needed.

Household and biotechnological methods toreduce the pollution of waters by alkyl sulfates •Tatsiana Pasko & Anna Kotikova

L

Domestic waste (for ex. domestic septic tanks) is an
important source of alkyl sulfate to the environment.
We have developed, tested, and offered a simple way to use
soap economically. These methods are easy to use, environmentally friendly, cost-effective, and take into accountsavings in both soap and water. Also, we have developed abiotechnological method of microbial purification using
our own detected bacteria and developed biological productbased on it. Sharing household and biotechnologicalmethods can significantly reduce the environmental
pollution by alkyl sulfates of domestic origin.

Carbamazepine (CBZ) is a recalcitrant pollutant
that enters natural water systems via humanexcretion 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 forbioremediation can be a cost-effective and an
environmentally-sustainable solution to address
CBZ pollution.

Flash flood prevention system• Neophytos Fikardou & Evdokia Charalambous
Flash floods are a growing problem for areas withshort intense rainfall patterns. Large volumes of
surface water carry with them debris that block
traditional drains. This project introduces the ideaof combining side drain inlets, the process of
sedimentation, garbage disposal units, andwater triggered sensors to eliminate the problemof blocked storm drains and therefore reduce therisk of flooding. The project includes a collectionof ideas involving a side inlet, a collection box, awater detector and a garbage disposal. The aim is toquickly remove water from the streets in order toprevent floods and more correctly flash floods.

Investigating wellwater quality by liquid
scintillation counting and potentiometricdetermination • 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 themunicipalities should provide the well water quality
tests for free.

Bubble alarm versus surfactants • Quentin
Meyer, Elodie Leroy & Arthur Boulay
When a water drop falls on the water, we can hear aparticular sound. We realized that it is an air bubble
vibration that gives this sound. We showed that thevibration 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 ofwastewater. This method is more environmentallyfriendly than the existing ones, and its playful side
contributes to raise awareness to a wide public.

The Secrets of Drinking Water – How to Combat
Polyethylene Terephthalate • Tamás Gergely
Iványi, Márton Czikkely & Tamás Márkus
Our research started from the realisation thatthe yearly growth in discarded polyethylene
terephthalate bottles combined with misbeliefs
about tap water will lead to an ecologicalcatastrophe. 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 theconsumers and ascertained its excellent quality.
We proposed four easily implementable ways
to diminish the dumping of used PET
into the environment.

Microplastics – A growing problem •Julia Henrike FreundIn 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 fora retention of microplastics. I developed a model
system and integrated it into the flow process chartof a sewage plant.

Our project is an environmental study about abeautiful but forgotten area in our region: the Sclusésbasin. 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 andcatalogued the benthonic organisms, the water-plants,
and the vegetation along the banks. The data we collected
showed some critical aspects, so we decided to makeour results known to the local population and to ask theadministrators for some improving actions.

Removal and detection of fluoride by
developing a filtration system of activatedcarbon impregnated • Guillermo Gael Wells
Abascal & Ana Laura Martínez Pacheco
There are many water treatment methods to eliminate
fluoride but these methods are expensive for Mexicoand other developing countries. This project creates asimple treatment to remove fluoride concentrations inunderground water and suggests an implementationof 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.

Blue battery • Eline Jagtenberg, Lotte vander Velde & Mei Nelissen
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 generating electricity. Solar/wind energy will be reversed
into chemical energy, using electro dialysis. Whenneeded, chemical energy is transformed into electrical 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 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 werealso 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 qualitychanged in relation to the weather and season, and notthat much due to the fields. The main reasons werethat the topography was very flat and the initiatives
from the farmers.

Present work highlights the biomass and biogas from flowersof Calotropis procera . The biomass of flowers that was evaluatedfor 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) andpolar (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 biogasthat was produced from solid residues of calotropis
procera were used as energy source in thermic power
plant due to its high levelof organic constituents.

Phosphate recovery from livestock wastewaterusing 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 eutrophication 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 forremoval 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), andzinc ions was studied. The results show that the
maximum adsorption capacities of wastepaper for
all the three metal ions were higher than that ofactivated carbon. When used as filtration media forvarious types of filter (simple column, ceramic andcontinuous upflow), wastepaper was able to removeat least 85 per cent, 95 per cent, and 40 per centof metal ions respectively. Wastepaper has thepotential to be used as an adsorbent to purify
water polluted with metal ions.

Our project is about a water conservation method
which can minimize or control water wastage in our
school, community, and country. 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 thewater flow. A person can call cell phone A to open,
call cell phone B to close, or setting an alarm forboth cell phones in order to open and closeat the specific time.

Fish out of thin air • Renatus Groothoff& Sebastian Groothoff
Tomorrow’s oceans could be void of fish if thefishing 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 usedby fish farms is derived from wild fish.
We hypothesised that using photosynthesis andbacterial nitrogen fixation in an aquaponic system
we could harvest the four main elements of all
biological molecules directly from the air orwater turning these into fish protein.

Rapid advances in technology in the 21st century
have resulted in the recent and significant rise ofelectronic 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 ofnanotechnology, a fully regenerable, sustainable,
efficient, and first-of-its-kind filter has been createdthat can remove over 99 per cent of heavy
metal contaminants from drinking andindustrial wastewater.
