Desalination

The author asserts that desalination of seawater is a promising way of reducing freshwater shortages, but it is expensive, complex, and can have environmental consequences. The author claims that groundwater is sensitive to external forces such as tides, hurricanes, and climate change…

Malthusian Prophecy As a child growing up in the Michigan winters, I grew fond of the snow. As I grew older, the winters seemed to become less intense in regards to frequency and amounts of snowfall. Perhaps this was confirmation bias at work. However, I recently asked my father if he had ever told himself or others, “We don’t have winters like we used to.” He humbly replied yes, that he had thought about it. That is an example of global warming. It wasn’t just my confirmation bias at work; it…

The Earth is beautiful and precious, but its beauty can mask unaware people of the deep wounds below its surface. Like humans, this planet has its own unique flaws. In this case, the Earth suffers from scars that are continually getting deeper. As the world’s water basins, rivers, creeks and other freshwater sources are depleting by the gallons, it appears that water scarcity is no trivial wound. With its inhabitants’ lives at stake on this beautifully sad world, they need its tears to survive.…

4. Recent development of forward osmosis: As mentioned above, FO technology is faced by several challenges that limit its application in large scale processes. The development of FO process can be governed by two major factors; the development of high-performing draw solutions and highly efficient FO membrane. 4.1. Draw solutes development: The draw solution has several factors that can affect FO performance. These factors mainly comprise of draw and feed solution osmotic pressures [61], draw…

Travelling to the heart of Togo, one will find many villages lacking clean water. One will encounter children who spend half of their day walking for miles to and from a river, only to come back with buckets of unfiltered water, contaminated with disease. One will watch the people of these villages become infested with said disease, as it is the only water they drink. One will also discover villages struggling with thirst for two-fourths of the year while the wet season departs and the dry…

As we know that, on earth, the major part of water is saltwater so desalination systems have become a practical means of increasing freshwater supplies. Desalination is mostly useful in locations that lack necessary groundwater or rainfall but it can also supplement existing resources. There are some drawbacks of desalination. The marine ecosystem can get damaged as the highly concentrated brine that is ejected to the ocean. One way to lessen this…

both a specific pollutant and a specific body of water is no minor task. Along with TMDLs, desalination seems to be a practical idea, but as a matter of fact it is inefficient. To elaborate, desalination requires copious amounts of energy to produce an insignificant amount of distilled water. Furthermore, the process generates pollution due to the use of fossil fuels. In spite of the fact that desalination is expensive, destitute countries in need of clean water are without access to saltwater,…

The world is running out of water, 75% of the planet earth is covered with water out of that 97.5% is the ocean, 2.5% is freshwater but 70% of that is ice, 30% is groundwater and much of that is polluted. Which leaves only 1% safe water and out of that, 70% is used for irrigation, 22% for industry and 0.8% for domestic use that consists of basic tasks like sanitation, drinking etc (Heimbuch,2010). This issue is known as water scarcity it is the lack of sufficient water for daily needs, without…

1. INTRODUCTION By 2050, it is expected that the current global population would have increased by more than 50%. The countries with the greatest population growths ( Figure 2) are also situated in areas with the least availability of fresh water ( Figure 1). These countries are also predominantly poor and cannot implement expensive water retrieval and treatment methods. This results in great economic stress on wealthier countries. This report will provide information on the current water…
