How The Water Science and Technology Cleansing in the Coming Decades?

 

One of the most widespread problems affecting people worldwide is the lack of access to clean water as well sanitation. Water problems are expected to increase significantly in the coming decades, with global water shortages, even in regions currently considered to be water-rich. Dealing with these problems requires a very large number of researches to be developed to find new ways to clean water at a lower cost and less energy, while at the same time reducing the use of chemicals and the impact on the environment. Here we highlight some of the sciences as well as technologies are being developed to improve disinfection and eliminate water pollution, as well as efforts to increase water availability the provision of safe use of wastewater and the removal of active salt from the sea and boiling water.

The many problems around the world related to the lack of, clean water well known: there are 1.2 billion people in need access to safe drinking water, 2.6 million with little or no sanitation, millions of people dying, children, date from diseases transmitted by unsafe water or by humans taken out. Many others are afflicted with diseases and alimentation Intestinal infections and diarrhea caused by water-borne pathogens and enteric bacteria are the leading cause of malnutrition due to the digestion of human food water-borne in both developing and developed nations,

An increasing amount of Pollution enters the water supply from human activities: 

From traditional chemicals such as heavy metals and replicates emerging micropollutants such as endocrine disc racking with nitrosamines. Increasingly, public health and the environment- mental anxiety drives to attempt to destroy water in the past it is considered clean. The most efficient, least expensive, and most effective methods irrigation and drainage from the source to the point of use necessary, without further emphasis on the environment or endangering its human health by the treatment itself.

Water is also a major factor in the energy and production of food, which is industrial output, and the quality of our environment, which affects the economy of both developing and advanced nations. Many freshwater sources are polluted and overused in densely populated areas some are irreversible or plunge into salty waters in coastal regions.

In agriculture, livestock, and energy consumption more than 80% Of all water for human consumption, clean water is expected with population growth, some traditional sources are oppressive. The Switching to biofuels for energy can add additional irrigation requirements and refinement. Ironically, within 30 years snowfall could cause major rivers such as Brahmaputra, Ganges, Yellow (already existing) sometimes no longer running in the sea) and the Mekong rivers, which work China, India, and Southeast Asia, to some extent, have been in danger more than 1.5 billion people during the dry months. "nations in North America and Europe, and those in the Andes In South America, a major agricultural crisis could be seen, electricity and electricity generation, and municipal water supply on ice reduction and/or loss of glaciers " for decades, water scarcity could be a catalyst for action from mass migration to war, without new methods

A clean water supply is available.

Fortunately, a lot of work in medical research offers hope in reducing the impact of inefficient water around the earth. Standard methods of disinfection, contamination, and salt removal can address many problems with quality and feed. However, these therapies often focus on chemicals, energy, and efficiency focusing on large Systems, and therefore, requires significant investment, engineering technology, and infrastructure, all of which hinder their use of many the earth. Even in the most developed countries the cost and time were needed to improve the current state of water and wastewater medical facilities make it difficult to deal with all the problems.

In addition, intensive chemical treatments (such as those involved ammonia, chlorine compounds, hydrochloric acid, sodium hydro vide, ozone, permanganate, alum and ferric salt, coagulation and filtering materials, anticipants, rust control chemicals, and ions exchange structures and regenerators) as well as treatment residues (mud, blisters, toxic wastes) can add to the problems of pollution and salinity of freshwater sources. In addition, it is chemical-intensive therapy in many regions of the world that cannot be used due to a lack of proper infrastructure.

However, even in central Europe, there has been a movement reducing chemical treatment through 'natural' systems designed to delay water production to reduce the remaining chemicals in distribution systems'. Fortunately, there is more than science and technology can reduce the impact on the environment and increased efficiency because current therapies are still stagnant far from the limitations of the laws of nature in their ability to separate chemicals, disable or remove horrible germs and chemicals, move water molecules, and move ions against a concentration gradient. Our expectation is that by focusing on the science of an aqueous interface between voters in the water and building materials used therapeutically, fresh, stable, inexpensive, safe, and durable.
