Reverse Osmosis Abstract
ABSTRACT: The aim of this paper is to discover whether human powered reverse osmosis is a viable option for producing potable water for developing countries. The matters at hand are to determine whether human power is enough to operate such a system, how much clean drinking water it will produce, and if it produces a reasonable amount for the work put in. A device was designed to test the practicality of this idea through a numerical analysis. A bicycle inspired design was chosen to harness human power effectively and efficiently. Pedal powered water pumping and purification is not only free from pollution but also provide healthy exercise. Pedal powered water pumping and purification reduces the rising energy costs.
Experimental result shows that discharge of about 0.6 l/m can be obtained, and the Total dissolved salt (TDS) is around 50ppm and pH value is around 7.13 for filtered water.
Keywords: potable water, filtration, reverse osmosis, human powered, developing countries.

“Nearly one billion people do not have access to clean drinking water”. That is about one eighth of all the people living on earth right now. Every year, almost four million people die from water-related diseases and 98% of those occur in the developing countries. Humans can live for weeks without food, but only a few days without water. Many people in developing countries barely have access to any water source at all and for those that do, the water is completely filthy and disease-ridden. Clean water is not only a right of people but also a prime necessity to have healthier lives hence our objective is to design a system which filters water for villages and Remote places by harnessing the human pedal
Elodea Lab
1022 Words | 5 PagesElodea” was put into a tank labelled “chemically treated Elodea”. Three drops of phenolphthalein were added to each beaker and then all of them were placed on a sheet of white paper. 0.02N NaOH was slowly added to the “tap water with Elodea” beaker with a dropper that delivers 0.025 mL per drop. Each drop was counted and the solution was stirred thoroughly before adding the next drop. This was continued till a faint pink color appeared in the solution.

Energy A Beginner's Guide By Vaclav Smil
807 Words | 4 PagesWater as a renewable energy source has been used within human society since the creation of the water wheel. Hydroelectricity continues to be utilized today in countries such as the United States and is an obviously viable option to clean, renewable energy. However, Energy: A Beginner’s Guide by Vaclav Smil, reveals the consequences of hydropower that most people are generally unaware of. I decided upon hydroelectric power to reflect on because I was initially in favor of using it as a substitute to fossil fuels such as coal, oil, and natural gas.
Fresh Water Supply By Zo Birdsong
415 Words | 2 PagesThe world’s freshwater supply is thinning out, and humans aren’t being careful with the precious amount of water that remains. The world may not have as much freshwater as one might think it does. 70% of the world is water (National Geographic). Of that 70%, only 2.5% of that is fresh (National Geographic).Even then, most of that 2.5% is not easily accessible (National Geographic). In the next 10 years, an estimated 1.8 billion people will be living in water scarcity (National Geographic).

Since the first well 667 wells have been built, giving water to over 714, 000 people, and Ryan’s Well Foundation was created. In actuality many people know of the clean water issues in Africa, but Hreljac choose to help.
Osmosis In Patients
141 Words | 1 PagesIn hospitals patients sometimes receive fluids by intravenous injection. Doctors choose a salt solution and never plain water to inject into humans. You know that blood is composed mainly of red blood cells. Use your knowledge of osmosis to explain why doctors make this choice? Osmosis is the diffusion of water across a selectively permeable membrane from an area of higher water concentration to an area of lower water concentration.

The California Drought
2045 Words | 9 PagesThere are currently at least 663 million people in the world who do not have access to safe drinking water (Deen). Water is a vital resource that everyone depends on in order to carry out activities and simply to survive. Without water, life on Earth would not exist because in order for life to grow and thrive, including humans, depend on water. Unfortunately with increasing population, altered and changing weather patterns and the pumping of groundwater are factors that have contributed to the issue of water depletion. These issues have caused conflict over water transportation, usage and the potential of water weaponry.
Rain Water Persuasive Speech
611 Words | 3 Pages- We came up with this idea after we heard about this seed called the miracle seed. It's called the moringa oleifera. One of these seeds can purify between one and four liters of water. You take these seeds and you crush them up into a fine powder, mix it up, let it settle, and then you've removed between 90 and 99 percent of bacteria, heavy metals, and all the stuff that you don't wanna drink. The map of the world that needs clean water and where the seed grows is pretty much one to one.
Water Wheels: The Water Wheels Of Ancient China
898 Words | 4 PagesA water wheel in Ancient China was used to crush grains or to cast iron. It was first invented by Nikola Tesla. A water wheel is a machine for converting the energy of falling water into some forms of power ("Wikipedia"). A water wheel consists of a large piece of wood with a few buckets arranged on the outside rim forming the driving surface ("wikipedia"). The energy changes are water energy of water to kinetic of water wheel to electricity of the generator/motor.

Potato Osmosis Lab Report
1078 Words | 5 PagesBiology Design Practical Joshua Edwards What are effects of the volume of a potato and the amount of weight it loses when placed in salt solution? Introduction This design practical uses a potato’s surface area to volume ratio to see what affects it has on osmosis in different concentrations. Osmosis is the movement of water molecules through a cell membrane into an area of a higher solute concentration. The movement goes the way of the solvent with more solute because the lower solute concentration is drifting through balancing the ratio of solute per solvent (En.wikipedia.org, 2018).
Congo SWEAT Analysis
1802 Words | 8 PagesAccording to a report by The United Nations Environment Programme (UNEP), “only around 26 percent of the DRC 's population of 67.8 million – equivalent to 17.6 million people – have access to safe drinking water, well below the approximately 60 percent average for Sub-Saharan Africa” (2011). Arguably, this is because the Congolese government lacks sufficient funds to lay pipes and improve its water pumping system. Congo is experiencing rapid population growth in its urban centers thereby making it hard to provide water for the extra number of people.
