This document outlines guidelines for preventing waterborne diseases through safe drinking water. It discusses how contaminated water can spread pathogens and cause over 2 million deaths annually, mostly in children in developing countries. Various waterborne diseases are classified based on their transmission route. The document then details conventional water treatment methods, including screening, aeration, coagulation, sedimentation, filtration, disinfection and pH adjustment to remove contaminants and make water potable.

Airborne disease can spread when people with certain infections cough, sneeze, or talk, spewing nasal and throat secretions into the air. Some viruses or bacteria take flight and hang in the air or land on other people or surfaces.
When you breathe in airborne pathogenic organisms, they take up residence inside you. You can also pick up germs when you touch a surface that harbors them, and then touch your own eyes, nose, or mouth.
Because these diseases travel in the air, they’re hard to control. Keep reading to learn more about the common types of airborne diseases and what you can do to protect yourself from catching them.
Water purification methods are very necessary at industrial level. Its also necessary to purify water for drinking purpose and its use in agricultural areas.
Water-borne diseases and water-caused health problems are mostly due to inadequate and incompetent management of water resources. Sometimes the water gets contaminated at source due to various reasons and mainly due to inflow of sewage into the source.
We can work together to keep the environment clean so the plants, animals and people who depend on it remain healthy :) Working together, we can make pollution less of a problem and make our world a better place :D :)

All living things require clean, uncontaminated water as the most crucial compound for life on Earth
Ideally, drinking water should be clear, colorless, and well aerated, with no unpalatable taste or odor, and it should contain no suspended matter, harmful chemical substances, or pathogenic microorganisms.
Wastewater discharge from industries, agricultural pollution, municipal wastewater, and poor environmental sanitation are the main sources of water contamination
Water :the universal need. As we all know water is most essential component to mankind yet its quality is in hazardous state and quantity is declining. This slide contains crucial information about water purification systems like what happens to water before we get it I'm our home?!

Defecation
Normal defecation begins with movement in the left colon, moving stool toward the anus. When stool reaches the rectum, the distention causes relaxation of the internal sphincter and an awareness of the need to defecate. At the time of defecation, the external sphincter relaxes, and abdominal muscles contract, increasing intrarectal pressure and forcing the stool out
The Valsalva maneuver exerts pressure to expel faeces through a voluntary contraction of the abdominal muscles while maintaining forced expiration against a closed airway. Patients with cardiovascular disease, glaucoma, increased intracranial pressure, or a new surgical wound are at greater risk for cardiac dysrhythmias and elevated blood pressure with the Valsalva maneuver and need to avoid straining to pass the stool.
Normal defecation is painless, resulting in passage of soft, formed stool
CONSTIPATION
Constipation is a symptom, not a disease. Improper diet, reduced fluid intake, lack of exercise, and certain medications can cause constipation. For example, patients receiving opiates for pain after surgery often require a stool softener or laxative to prevent constipation. The signs of constipation include infrequent bowel movements (less than every 3 days), difficulty passing stools, excessive straining, inability to defecate at will, and hard feaces
IMPACTION
Fecal impaction results from unrelieved constipation. It is a collection of hardened feces wedged in the rectum that a person cannot expel. In cases of severe impaction the mass extends up into the sigmoid colon.
DIARRHEA
Diarrhea is an increase in the number of stools and the passage of liquid, unformed feces. It is associated with disorders affecting digestion, absorption, and secretion in the GI tract. Intestinal contents pass through the small and large intestine too quickly to allow for the usual absorption of fluid and nutrients. Irritation within the colon results in increased mucus secretion. As a result, feces become watery, and the patient is unable to control the urge to defecate. Normally an anal bag is safe and effective in long-term treatment of patients with fecal incontinence at home, in hospice, or in the hospital. Fecal incontinence is expensive and a potentially dangerous condition in terms of contamination and risk of skin ulceration
HEMORRHOIDS
Hemorrhoids are dilated, engorged veins in the lining of the rectum. They are either external or internal.
FLATULENCE
As gas accumulates in the lumen of the intestines, the bowel wall stretches and distends (flatulence). It is a common cause of abdominal fullness, pain, and cramping. Normally intestinal gas escapes through the mouth (belching) or the anus (passing of flatus)
FECAL INCONTINENCE
Fecal incontinence is the inability to control passage of feces and gas from the anus. Incontinence harms a patient’s body image

Medical Technology Tackles New Health Care Demand - Research Report - March 2...pchutichetpong
M Capital Group (“MCG”) predicts that with, against, despite, and even without the global pandemic, the medical technology (MedTech) industry shows signs of continuous healthy growth, driven by smaller, faster, and cheaper devices, growing demand for home-based applications, technological innovation, strategic acquisitions, investments, and SPAC listings. MCG predicts that this should reflects itself in annual growth of over 6%, well beyond 2028.
According to Chris Mouchabhani, Managing Partner at M Capital Group, “Despite all economic scenarios that one may consider, beyond overall economic shocks, medical technology should remain one of the most promising and robust sectors over the short to medium term and well beyond 2028.”
There is a movement towards home-based care for the elderly, next generation scanning and MRI devices, wearable technology, artificial intelligence incorporation, and online connectivity. Experts also see a focus on predictive, preventive, personalized, participatory, and precision medicine, with rising levels of integration of home care and technological innovation.
The average cost of treatment has been rising across the board, creating additional financial burdens to governments, healthcare providers and insurance companies. According to MCG, cost-per-inpatient-stay in the United States alone rose on average annually by over 13% between 2014 to 2021, leading MedTech to focus research efforts on optimized medical equipment at lower price points, whilst emphasizing portability and ease of use. Namely, 46% of the 1,008 medical technology companies in the 2021 MedTech Innovator (“MTI”) database are focusing on prevention, wellness, detection, or diagnosis, signaling a clear push for preventive care to also tackle costs.
In addition, there has also been a lasting impact on consumer and medical demand for home care, supported by the pandemic. Lockdowns, closure of care facilities, and healthcare systems subjected to capacity pressure, accelerated demand away from traditional inpatient care. Now, outpatient care solutions are driving industry production, with nearly 70% of recent diagnostics start-up companies producing products in areas such as ambulatory clinics, at-home care, and self-administered diagnostics.
Health Education on prevention of hypertensionRadhika kulvi
Hypertension is a chronic condition of concern due to its role in the causation of coronary heart diseases. Hypertension is a worldwide epidemic and important risk factor for coronary artery disease, stroke and renal diseases. Blood pressure is the force exerted by the blood against the walls of the blood vessels and is sufficient to maintain tissue perfusion during activity and rest. Hypertension is sustained elevation of BP. In adults, HTN exists when systolic blood pressure is equal to or greater than 140mmHg or diastolic BP is equal to or greater than 90mmHg. The

2. Introduction
● Drinking water is a major source of microbial pathogens in
developing countries.
● Waterborne disease cause more than 2 million deaths
and 4 billion cases of diarrhea annually.
● 9 out of 10 deaths are in children and virtually
all of the deaths are in developing
countries.
3. Terms to be known
1. Potable(clean) water:
It is free of all objectionable material, including
pathogens, tastes, odors, colours, toxins, radioactive material,
organisms, oils, gases, etc.
2. Contaminated or polluted water
Water contaminated with sewage, domestic or industrial
waste with chemicals and pathogenic microorganisms
5. Water-borne diseases:
Diseases caused by ingestion of water
contaminated by human or animal faeces
or urine , which contain pathogenic
microorganisms.
Water-washed Diseases:
Diseases caused by poor personal hygiene and skin and eye contact
with contaminated water
6. Water-based Diseases
Water-based diseases are caused by organisms by different species
of worms that spend parts of their life-cycle in different habitats.
● They have spent one development cycle in aquatic molluscs, and
another as fully grown parasites in other.
Vector-borne Diseases:
Vector-borne diseases are caused by bites from
insects that breed in water.
● Insect vectors such as mosquitoes transmit
diseases such as malaria,
Chikungunya .
11. Water-borne disease caused by
Chemicals
● Arsenic
● Fluoride
● Nitrates from fertilizers
● Carcinogenic pesticides (DDT)
● Lead (from pipes)
● Heavy Metals
● Chromium
● Nickel
● Cyanide
12. Treatment Of Drinking Water
● Water treatment describes those industrial-scale processes
used to make water more acceptable for a desired end-use.
● These can include use for drinking water, industry, medical and
many other uses.
Objective -To remove existing contaminants in the water, or reduce
the concentration of such contaminants so the water becomes fit
for its desired end-use.
13. Conventional Method for Water Sequence
of stages :
1. Screening
2. Aeration
3. pH correction
4. Coagulation and flocculation
5. Sedimentation
6. Pre-chlorination and dechlorination
7. Filtration
8. Disinfection
9. pH adjustment
14. 1. Screening
➔ removal of coarse floating objects
➔ weeds
2. Aeration
➔ dissolving oxygen into the water
➔ removes smell and taste
➔ promotes helpful bacteria growth
➔ precipitates nuisance metals like
iron and manganese.
15. 3. pH correction
➔ Pure water has a neutral pH (that is 7 on the PH scale).
➔ Impurities in water and the treatment steps can make it either acid or alkali.
When water has undergone coagulation with Alum (see COAGULATION)
the pH is reduced.
➔ Lime may also be added to set the pH to lower levels, which is the level
where chlorine kills germs most effectively. Once the chlorine has done it’s
work (see CHLORINATION) then the water is set back to neutral which is
safe and ready to go to your house.
16. 4. Coagulation and flocculation
➔ add coagulating agent (aluminum sulfate or iron sulfate)- causes
agglomeration (clumping) and sedimentation of solid particles
➔ these solid particles are called floc or sludge.
17. 5. Sedimentation
➔ Floc settles out and is scraped and vacuumed off the bottom of large
sedimentation tanks.
➔ Clarified water drains out of the top of these tanks in a giant decanting
process.
6. Pre-chlorination and dechlorination
➔ Mostly to kill algae that would otherwise grow and clog the water filters.
➔ Also kill much of the remaining bacteria
18. 7. FILTRATION
“In order to remove or to reduce the contents of impurities still further, the water
is filtered through the beds of fine granular material like sand”
● Rapid-sand filters
➔ force water through a 0.45-1m layer of sand and work faster, needing a
smaller area.
➔ But they need frequent backwashing
● Slow-sand filters
➔ require a much larger area but reduce
bacteriological and viral levels to better due
to the Schutzdecke (biofilm) layer.
➔ The top 1 inch of biofilm must
be periodically scraped off and the filter
occasionally back
19.
20. 8. Disinfection
Water completely free of suspended sediment is treated with a powerful
oxidizing agent usually.
➢ Chlorine- Dosage- 5 mg per litre.
➢ Chloramine (chlorine and ammonia)
➢ Sodium hypochlorite solution (5%)
➢ Ultraviolet radiations
➢ Ozonation
9. pH adjustment
So that treated water leaves the plant in the desired range of 6.5 to
8.5 pH units.
