I studied adsorption and kinetic of Cd2+, Cu2+, Fe2+ and Fe3+ ions by Sphagnum Moss.
I did research if there is any relationship between these ions and which ions moss are adsorpted the most.
I came up to conclusions, it is possible to determine the air and water pollution by Sphagnum moss.
I studied pollution with these metal ions in 5 different places in Vilani and discovered where the most particular metal ions are.
According to my results it can be done preventive measurements for prevention of pollution in the future. The research can be repeated every 5 years. Results and changes will be compared and evluated. The moss purifies the water and cleans the air by absorbing the metal ions.

This study is focused on developing a water capsule to tackle drought, decreasing the water wasted from agriculture. By burying small capsules that steadily eject water near the roots, the immense amount of water that evaporates after being sprayed on crops can be saved. This study first discusses the method of fabricating sphere-shaped alginate capsules, involving ice balls. Alginate is a polymer that can form membranes by cross-linking with divalent cations. Then it determines the ideal composition and concentration of the alginate membrane using Young’s modulus comparisons to measure the stiffness. Experiments were conducted to measure the discharged water over time for each type of capsule.

A method for family households is employed to obtain drinking water from river water by treating it with seeds of
Moringaoleifera lam. The seeds will eliminate the river water turbidity. Subsequent heat or chemical disinfection
is needed. The number of seeds used is adjusted to the water turbidity by a self-designed dispenser. In the tests
carried out, after its application, the results obtained were found within the limits indicated for drinking water.

It is forecast that 66% of our population will experience water scarcity within a decade, leaving us more dependent on surface water for drinking. This requires more filtration infrastructure, and more monitoring of surface water. Current methods rely on expensive and technically challenging manual identification of biological samples. Macroinvertebrates spend their larval lives within a small area of water, showing cumulative effects of habitat alteration and pollutants that chemical testing and field sensors do not. Chironimidae are a global common denominator. DNA Barcoding of Chironomidae results in more accurate and precise waterway health data, adding significant value for monitoring scarce water resources. The learnings from these data are being applied building microbiology capability at a nonprofit scientific water study institute.

A Gamma Water Tank had been created to produce safe domestic water. Tests had been run to prove the safety of the Gamma Water Tank.
The raw water was first being treated with alum in screening tank. Then the water flow through the screening tank into the sedimentation tank. In the sedimentation tank the velocity of flow which carries the water horizontally will settle the particle at the bottom of the tank. The water then being aerated to remove dissolved gases. The water is then being filtered before being added with chlorine. All of the water samples go through some tests which are pH test, Biochemical Oxygen Demand (BOD) and Chemical Oxygen Demand (COD).

It is reasonably certain that microplastics are the most dangerous pollutants of plastic for aquatic organisms and humans. Thus far, there is not yet a large-scale system in place to eliminate microplastics from major bodies of water. In this report we describe different developmental phases of one such design and suggest possible applications. It is named ‘The Banana’, and takes its name from its distinctive shape.

Throughout developing and developed countries, the proliferation of mining and smelting operations continues to occur. This industry is crucial to the economic development and states of nations across the globe. This impact includes contamination of surrounding bodies of fresh drinking water with heavy metals. To scientifically address this concern, an eco-friendly biopolymer was embedded with mechanically isolated tannins from oak leaves. The biopolymer was then used to extract sample heavy metals from contaminated water. The results were measured using the change in mass, change in clarity, change in concentration of metal in water, and the effects on radish seedling germination. It was found that using a tannin-embedded biopolymer is an economically and eco-friendly way to remove heavy metals from water.

Chocho (Lupinus mutabilis) is a traditional Andean bean that in the last years has gained importance due to its widely appreciated nutritional value. Chochos need to be processed before their consumption because of the presence of alkaloids (chemicals that protect the plant against insect attacks). Chochos are grown by farmers in the Ecuadorian Andes, they are then dried and stored for their commercialization. For consumption, chochos need to be rehydrated, sadly the water is usually discharged. The main issue covered is the unnecessary waste of water which originate from the rehydration of chochos. This project aims to test the possibilities of upcycling the debittering water as an irrigation water for crops.

Aquaculture is one of the most promising industries for low-volume private agriculture in Belarus. But breeding fish in ponds leads to changes in water quality, resulting in eutrophication and subsequent pollution.
To speed up the processes of biological rehabilitation the use of the method of biological rehabilitation due to the algolization of the alga Chlorella vulgaris is possible.
In order to assess the effectiveness of using the algolization method we conducted it with our own strain and estimated a number of water parameters, also productivity of mirror carp.
Thus, we obtained data indicating the high efficiency of algolization of fish ponds which was expressed in improving the water and increasing the carp productivity, thereby achieving an economic effect of algolization.
