Water Borne Disease and how to cure them

1. Water Borne Disease and How to cure them

2. Description Water-related disease The risk of disease is extremely high when clean water and adequate sanitation don't seem to be accessible. Contaminated water contains bacteria and viruses that cause diseases and Suspended solids, little particles of dirt or earth that make water cloudy or brown are likely to hold such pollutants aretherefore undesirable. certain metals and minerals i.e. pb (Lead) and Arsenic (As) are toxic and others are dangerous in high concentrations. the leaching of fertiliser and pesticides, as and bacteria can cause diarrhoeal diseases like cholera, typhoid fever, E – coli infection, hepatitis a, polio and Legionellosis (Legionnaire’s disease). this is an acute issue particularly in diseases are perfectly treatable, these countries they may be lethal, owing to the lack of sufficient medical aid. A vicious circle forms when waste is disposed of and contaminates water. one of the most common contaminants is bacteria from faecal matter that enters the water when it cannot be disposed of properly. may contain poisonous chemicals. Chemicals often return from example nitrate. an Viruses developing countries. These but in in developing countries Water-borne diseases Water-borne diseases are the most widely known; caused by organisms that may survive in water (such as E.coli and salmonella and viruses that cause hepatitis A and pathogens are simply ingested when contaminated water is drunk. because of the short life cycles small number can multiply very rapidly, spreading the sickness. Polio). These of bacteria and viruses, a Water-washed diseases Water-washed diseases like some diahorreal diseases and skin-and eye infections like scabies and trachoma, cansimply take hold when adequate clean water isn't accessible for personal hygiene. when water scarce, washing usually takes a back seat to the need to drink. is

3. Water-based diseases Water-based diseases are such that parasites that spend a part of their life cycle in water can be ingested whenwashing, swimming or drinking the water. Examples are intestinal worms and schistosomiasis (Bilharzia). Water-associated vector-borne diseases Water-associated several insects that carry diseases. as an example mosquitoes that usually breed in still water. the most well-known and dangerous are malaria and yellow fever. vector-borne diseases: Water provides a habitat for Water purification Filtration Most, if not all, water purification systems contain a filter stage. These filter out massive things from sewage water, like cotton wool and condoms that should not have been thrown down the bathroom in the 1st place. Filters can also remove smaller particles like silt and suspended solids; dissolved ions and a few filters catch bacteria and viruses. generally used technique in developing countries. one of these filtration ways is that the sand filter. as the name implies, sand filters filter water through sand and gravel, therefore mimicking nature as groundwater percolates through the ground. There are two types of sand filters: a rapid sand filter and a slow sand filter. rapid sand filters filter water through sand, however speed up the method by using chemicals similarly. rapid sand filters may use flocculation (see p. 15) with aluminium and iron. Slow sand filters however, use no to function, however they're typically massive and need massive areas if used municipally. Slow sand filters consist of a layer of fine grain sand supported on a layer of gravel, the topmost layer consisting of a biofilm (a layer of biological activity referred to as a schmutzdecke), bacteria fungi and a spread of aquatic larvae that have been caught micororganisms help to metabolise organic material in the water, cleaning it. Sand filters need a while to mature, usually 10-20 days before the filtered water Filtration is the most chemicals or electricity there. As this builds up,

Slow sand filters need a more or less continuous flow of water to avoid drying out the biolayer and to ensure a continuous flow of nutrients to support the microorganisms within the biolayer. as the filter is used, the schmutzdecke will grow larger and consequently will reduce the flow rate of the filter. when rate of flow becomes to be cleaned by emptying the filter and scraping off the highest layer of sand.9 because slow sand filters are slow, the water needs a long time to get through the limited, although they're relatively simple to showing a slow sand filter. safe to drink. The water that flows through the too low, the filter has sand and capability is Below is manage. a diagram To buy Kent RO water purifier and prevent water-borne diseases please visit https://www.kentrosystems.eu/
