Main Menu: Pathogens Are Disease-Producing Micro-Organisms



Microbial Pathogens.Pathogens in drinking water are serious health risks. Pathogens are ‘diseaseproducing’ micro organisms, that include bacteria, viruses, and parasites. They get into drinking water when the water source is contaminated by sewage and animal waste, or when wells are improperly sealed and constructed. They can cause gastroenteritis, salmonella infection, dysentery, shigellosis, hepatitis, and giardiasis. The presence of coli form bacteria, that is generally a harmless bacterium, may indicate other contamination to the drinking water system.

Organics.People worry the most about potentially toxic chemicals and metals in water. Only a few of the toxic organic chemicals that occur drinking water are regulated by drinking water standards. This group of contaminants includes. -Trihalomthanes, that are formed when chlorine in treated drinking water combines with naturally occurring organic matter. -Pesticides, including herbicides, insecticides, and fungicides. -Volatile organic chemicals, that include solvents, degreasers, adhesives, gasoline additives, and fuels additives. Some of an ordinary VOCs are. Benzene, trichloroethylene, styrene, toluene, and vinyl chloride. Possible chronic health effects include cancer, central nervous system disorders, liver and kidney damage, reproductive disorders, and birth defects.

Inorganic.These contaminants include toxic metals like arsenic, barium, chromium, lead, mercury, and silver. These metals can get into your drinking water from natural sources, industrial processes, and the materials used in your plumbing system. Toxic metals are regulated in public water supplies being that they can cause acute poisoning, cancer, and identical health effects. Nitrate is another inorganic contaminant. The nitrate in mineral deposits, fertilizers, sewage, and animal wastes can contaminate water. Nitrate is associated with dark blue baby syndrome in infants.

Bring it to the boiling point. Radon in air is associated with lung cancer. Seriously. Place water in a container over heat. Hold it at this temperature for ‘1520’ minutes. Radon is a radioactive contaminant that results from the decay of uranium in soils and rocks. Make sure you leave. Perhaps you have used this technique after a flood or when a water main has burst as an emergency aid. Boiling water is an effective method of treatment as no important waterborne diseases are caused by heat resisting organisms. That’s Such an organism must react exactly as do the contaminating organisms both in the natural water supply and in treated water. It is usually more of a health concern when it enters a home as a soil gas than when it occurs in water supplies. Write An organism serving as a reliable measure of contamination must indicate the potential presence of specific contaminating organisms in either a natural water or one subjected to treatment. This will disinfect the water.

The use of ultraviolet light is an attempt to imitate nature.

water deionization processExposing water to ultraviolet light destroys pathogens. Notice that otherwise some bacteria going to be protected from the germkilling ultraviolet rays. Ultraviolet light treatment has no residual effect. Further, it must be closely checked to assure that sufficient ultraviolet energy is reaching the point of application all the time. Basically, sunlight destroys some bacteria in the natural purification of water, as you recall. However, most of us know that there is little possibility of its creating taste or odor problems, since ultraviolet light adds nothing to the water. Water must be free of turbidity and color, to assure thorough treatment.

The most common method of treating water for contamination is to use the various chemical agents available. Bromine is easy to feed into water and ain’t hazardous to store. Among we are looking at chlorine, bromine, iodine, potassium permanganate, copper and silver ions, alkalis, acids and ozone. Now please pay attention. Let us review them briefly here.

Then again, it apparently does not cause eye irritations among swimmers, nor are its odors troublesome. Needless to say, So it’s rated as a decent germicidal agent. Bromine is an oxidizing agent that was used quite successfully in the disinfecting of swimming pool waters.



Amidst the most widely used disinfecting agents to insure safe drinking water is chlorine.

Chlorine in cylinders is used extensively by municipalities in water disinfection. Not enough is yet known about the physiological effects of iodine treated water on the human system, while such test results are encouraging. Besides, its use must be considered only on an emergency basis. Anyway, the residual required varies inversely with contact time, as usual. Now regarding the aforementioned fact… Tests show that 20 minutes exposure to 0 iodine ppm is adequate to render potable water. While higher residuals require shorter contact time, lower residuals require longer contact time. Consequently, in this form, chlorine gas is far should be used for treatment of drinking water. Much work at present now is done to test the effect of iodine in destroying viruses, that are now considered among the pathogens most resistant to treatment.

Silver in various forms is used to inhibit the growth of microorganisms.

Further, organic matter does not interfere with its effectiveness as is the case with free chlorine. They are rendered inactive, when some bacteria species come into contact with this silver. Its high cost, interferences by chlorides and sulfides, need for long periods of exposure, and incomplete bactericidal action have hindered its widespread acceptance. It is most frequently found combined with activated carbon in filters. With that said, silver does not produce offensive tastes or odors when used in water treatment. Remember, it has found lesser effect on viruses, cysts, and identical bacteria species, many of us are aware that there is disagreement among the experts as to the effectiveness of this process as silver ions in water kill coli very well and probably also salmonella. And therefore vibro bacteria.

Copper ions are used quite frequently to destroy algae in surface waters. They will need to avoid dehydration in general costs, I’d say in case someone is prone to kidney and urinary ailments. Moreover the cause of many aliments, especially kidney infections and similar disorders that can lead to more serious matters, dehydration isn’t only a symptom. For example, these ions are relatively ineffective in killing bacteria. Usually, they increase urine output and dehydrate the body faster, as do alcoholic beverages. On top of that, during hot weather and exercise, So it’s even more important to replenish fluids that may been lost through water and even the occasional sports drink. Of course, copper sulfate, as an example, is also used to kill algae in reservoirs. Nevertheless, they will look for to avoid caffeinated beverages, just like coffee and colas. People will need to drink at least 48 water ounces per day, and will look for to promptly treat any illnesses that cause dehydration, like diarrhea, vomiting, or fever. Perhaps the easiest and most effective ways is to avoid dehydration.

While resulting in a thickening and hardening of artery walls, a disorder called arteriosclerosis, Having an awful lot of water will keep your blood ways clean! Ok, and now one of the most important parts. Let’s so known as hypertension. In fact, consumption of water so you are fully hydrated can increase your metabolic rate! Furthermore, just like high cholesterol, high blood pressure can threaten healthy arteries and lead to life threatening conditions like heart disease and stroke. Together with a healthy diet, is an important contribution to the lowering of cholesterol, if again, water needs to be drank with intention to replenish what was lost, since exercise. While making in a natural way to there’re not any real symptoms until, that is why high blood pressure is known as the silent killer. Just like air in a tire, blood fills arteries to a certain capacity, and anything over that capacity can have damaging effects.

you can count out beverages similar to coffee or alcohol, while some fruit juices and light green tea may account for some fluid intake. They have a mild diuretic effect, that promotes urination and therefore water loss, that ultimately defeats the purpose.
