Water is beneficial in everyday purpose. From drinking to daily needs , from navigation to hydroelectric powerplants. many existing sources of water are being stressed by withdrawals from aquifers and diversions from rivers and reservoirs to meet the needs of homes, cities, farms, and industries. Consideration must also be given to leaving water in the streams and rivers to meet environmental, fish and wildlife, and recreational needs.

WATER POLLUTION

sakshisawant1902 — 2021-02-03 08:31:45 UTC

SAKSHI SAWANT
Water pollution happens when toxic substances enter water bodies such as lakes, rivers, oceans and so on , getting dissolved in them , lying suspended in the water or depositing on the bed. This degrades the quality of water.
Not only does this spell disaster for aquatic ecosystem,the pollutants also seep through and reach the ground water, which might end up in our households as contaminated water we use in our daily activities, including drinking.

Application of Water in Medical Field

madhmatithatte18 — 2021-02-03 13:48:31 UTC

Water plays an important role in the Health care field. From washing surgical tools and equipment to creating a soothing environment for patients to have hydrotherapy, water is essential to the effectiveness of the health industry. However, moist environments and liquid solutions can create a favourable setting for the growth of many bacterial and protozoal microbes. waterborne diseases can be spread through:
1. Direct contact(eg, hydrotherapy)
2. Ingestion of water (eg, Drinking water)
3. Indirect-contact (Medical/dental tool/equipment)
4. Inhalation of aerosols from water sources
5. Aspiration of water
6. Blood contact (eg, hemodialysis)
Due to weakened immune systems of many patients, the water used in health care settings mustn't be contaminated. Hydrotherapy involves the use of water for soothing pains and treating certain medical conditions.
HYDROTHERAPY: Hydrotherapy equipment includes pools, whirlpools, whirlpool spas, hot tubs, and physiotherapy tanks. Patients with medical conditions, such as burns, septic ulcers, lesions, amputations, and arthritis, can benefit from the effects of sitting in warm water. For the health and safety of patients, it is vital to ensure that the water that is used in hydrotherapy is safe and clean. Many of these patients have compromised immune systems due to current infections, and are highly susceptible to new infections from contaminated water in hydrotherapy pools. Potential routes of infection caused by contaminated water include accidental ingestion of the water, breathing sprays and aerosols from the water, and allowing wounds to come in direct contact with the water. Infection control for hydrotherapy tanks, pools, or birthing tanks presents unique challenges because naturally-occurring microbes, that may not be dangerous for a healthy individual, are always present in the water during treatments. The use of hydrotherapy for patients with wounds, burns, or other types of non-intact skin conditions should be considered on a case-by-case basis. Health-care providers should always consider the availability of alternative aseptic techniques for wound management, as well as a risk-benefit analysis of using traditional hydrotherapy. If hydrotherapy is used, facilities should maintain strict cleaning and disinfection practices by the manufacturer’s instructions
HEMODIALYSIS: During an average week of hemodialysis, a patient can be exposed to 300-600 litres of water, providing multiple opportunities for potential patient exposure to waterborne pathogens. Adverse patient outcomes including outbreaks associated with water exposure in dialysis settings have resulted from patient exposure to water via a variety of pathways; including the improper formulation of dialysate with water containing high levels of chemical or biological contaminants, contamination of injectable medications with tap water, and reprocessing of dialyzers with contaminated water. For the health and safety of hemodialysis patients, it is vital to ensure the water used to perform dialysis is safe and clean.
MEDICAL AND DENTAL EQUIPMENT: Certain pieces of medical and dental equipment can be directly connected to main water systems, including the automated endoscope reprocessor (AER) and certain dental units that are connected to water lines. It is highly important that these pieces of equipment use uncontaminated water during medical procedures. Certain microbes from water can contaminate medical equipment, causing nosocomial (hospital-related) infection and outbreaks of infection.
, Drinking enough water can help prevent certain medical conditions trusted source. These include:

constipation
kidney stones
exercise-induced asthma
Urinary tract infection
Hypertension

Water also helps you absorb important vitamins, minerals, and nutrients from your food, which will increase your chances of staying healthy.

How is waste water purified?

2021-02-03 15:46:45 UTC

Most wastewater undergoes secondary treatment as well as primary treatment. The most common method is to sprinkle or trickle the water over a bed of sand or gravel. As the water filters downward, it is put into contact with oxygen and microorganisms, which work together to break down the organic matter in the water.

Use of water in nuclear power plants

shadajjoshi — 2021-02-03 15:48:25 UTC

In order for nuclear power plants to work an enormous amount of heat is required & hence water is used as both cooling and the steam generator ... Producing hot steam mostly to rotate the generators and then eventually converting into POWER ! Water then is used to cool the steam and turn it back into water ... Hence Nuclear power plants cannot function without water & has a significant role to play in that industry , no need to argue how efficient that energy is & one of the pros is there's no contamination , so that's a good part of it !

halwaisanskar420 — 2021-02-03 16:00:56 UTC

Water... it is that liquid, which can bring life in living organism and simultaneously it has a capability of drowning the whole city or village.

Many industries, factories and major complexes which are mostly reliable on WATER. But we are here not to discuss it's usage on large scales, instead the post treatment of water after it's role, which is "The most important thing" to return nature into it's natural form.

Water contains many contaminations such as minute particles, oil globules, solid wastes, etc. which need to be processed before releasing it into natural bodies.

There are many ways which we are going to discuss...

Solid waste removals: This could be done in simple manner by easy sedimentation techniques. After such treatment if we are left with minute particles in it, that can be separated by many ultra-filtration methods.

Removal of oily and greasy substances: Industries which removes greasy and oil globules by water ways isn't done directly. The water has to go through process before releasing it to nature.
Industries have various separators which separtes water from emulsified solutions.

Why is it necessary to do such treatments?
We humans always have behaved carelessly towards nature. When water used to release without process, it resulted into blockage of water bodies, death roads for marine lives and severe threat to marine plants.
So government had to do something to save marine life. Many people worked a lot and put many efforts and came up with great ideas. Then government started making it compulsory to industries.

Impact of it: This post process really helped a lot to nature and specially marine life. Now such threats have reduced to great extents.

Nature have done a lot towards our well being. Now it is our responsibility to do something for her.

Sorry if it's too long😅

Water Scarcity.

mdsufiyanbepari — 2021-02-03 16:20:47 UTC

Do you know?                        Billion of People Lack Water.

When water run dry, people can't get enough water to drink, wash, or feed crops, and economic decline may occur. In addition, inadequate sanitation- a problem for 2.4 billion people- can lead to deadly diarrheal diseases, including cholera and typhoid fever, and other water-borne illnesses.

Water covers 70% of our planet, and it is easy to think that it will always be plentiful. However, freshwater-the stuff we drink, bathe in, irrigate our farm fields with- is incredibly rare. Only 3% of world's water is fresh water, and two-thirds of that is tucked away in frozen glaciers or otherwise unavailable for our use. As a result, some 1.1 billion people worldwide lack access to water, and total of 2.7 billion find water scare for at least one month of the year.

At the current consumption rate, this situation will only get worse. By 2025, two-thirds of the world's population may face water shortages. And ecosystems around the world will suffer even more.

Rainwater harvesting

rohitprasad1447 — 2021-02-03 16:30:57 UTC

Rainwater harvesting is the collection and storage of rain rather than allowing it to run off.Rainwater is collected from roof like surface and redirected to a tank or a reservoir. It uses include watering garden, livestock, irrigation, domestic use with proper treatment.Rainwater harvesting is one of the simplest and oldest method of self supply of water for households.

Water(H2O)= Life

2021-02-03 16:32:47 UTC

Water molecule is made up of 3 atoms. 2 atoms of hydrogen and one atom of oxygen. They have imbalanced structure and this makes them stick and attract different substances.

Some general points for the uses of water in various fields are as follow:

Domestic uses of water
Water use for agriculture
Industrial uses of water

1. 15 % of water is consumed for domestic purpose. Water is used for drinking, bathing, cooking food and washing dishes, clothes, fruits.

2. Agriculture is the largest consumer of water. About 70% of water is used for irrigation. Water is necessary for gardening, farming and fisheries. Plants require water to grow. During the process of photosynthesis, they consume water.

3. It is either used in creating or to cool the equipment used for creating the product. Industrial water is used for washing, cooling, processing, transporting, diluting or fabricating of a product.

WATER USE IN AGRICULTURAL FIELD

ashishvgudhekar22 — 2021-02-03 16:54:03 UTC

Water has always been a vital part of agriculture. Just like humans, crops need water to survive and grow. There are three areas of water use in agriculture: growing of crops ,supplying drinking water to livestock, cleaning farm building and animals the amount of each category varies according to the type of farm
Nearly 60 percent of the worlds fresh water that is used by humans in use of irrigation. Of this water applied to crop fields, only half returns to surface water or ground water sources.

We all know that if you trace the power lines far enough, you’ll eventually find a coal, gas, or nuclear plant, or perhaps a solar panel or wind turbine.But not everyone understands the relationship between electricity and water, which is used in various ways throughout the power sector. Understanding that relationship can help decision makers make smarter, more-informed decisions that produce better outcomes for consumers and the environment.Water is involved at many points in the process of producing electricity:Electricity Generation Fuel Extraction and Production Fuel Refining and Processing Fuel Transportation:Emissions Control Power plants using other cooling systems, known as recirculating or closed-loop systems, withdraw only a fraction of the amount that once-through systems do, but consume most or all of it. Power plant water consumption becomes a large problem in water constrained regions where competition among users is high.

APPLICATION OF WATER IN INDUSTRIES

2021-02-04 02:39:16 UTC

Without water many companies and the products they provide would fail to exist. Water use is a fundamental commodity for nearly every step of the manufacturing and production processes around the world.Whether it's deionised water for electronics and pharmaceutical sectors, or softened water for boiler feed applications, water is necessary and comes embedded in the footprint of virtually item created on the planet. And to put it into perspective: industry accounts for around 40% of total water abstractions. Yet, at the same time, many global companies have manufacturing facilities operating in water scarce parts of the world, with over two thirds of companies now reporting exposure to water risks.

INDUSTRIAL USES OF WATER:
1)Ultrapure water use in semiconductor manufacturing

Water is an essential component for the manufacturing of semiconductors and chips which are used everyday in computers, cell phones and automobiles. Ultrapure water is used throughout the process, including to remove impurities from silicon wafers. For example, a single 8” wafer, which is the foundation for approximately 100 chips, may require up to 2,000 gallons of UPW.

2)Cooling water

Cooling systems are used to remove heat from processes or equipment. Heat removed from one medium is transferred to another medium, or process fluid, which most often is water. According to the SUEZ Water Technologies Handbook, the driving force for the transfer of heat is the difference in temperature between the two media, which in most cooling systems, is in the range of 10-200 degrees F.

3)Water use in pulp & paper mills

Despite digitalisation prompting a move away from printed products, the pulp and paper sector remains one of the largest users of industrial process water in the US and the second largest in Europe. Water is intricately associated with 85% of all the three stages of paper production namely, pulp making, pulp processing, and paper/paper board manufacturing, and their associated activities of cooking, bleaching, and washing.
