What are the impurities in raw water?

These impurities include dust, fine sand, clay, dirt, and biological contaminants. Pure water is tasteless, colorless and odorless, but water from rainfall, streams and wells is known to harbor harsh chemicals and elements, including acid and metallic rust elements.

What are examples of impurities?

Destructive impurities Examples include ash and debris in metals and leaf pieces in blank white papers. The removal of impurities is usually done chemically. For example, in the manufacturing of iron, calcium carbonate is added to the blast furnace to remove silicon dioxide from the iron ore.

What are the 4 types of contamination?

This article has broken down the four main types of food contamination: chemical, microbial, physical, and allergenic. It has also highlighted a number of different scenarios that could cause the contamination of a food product and numerous ways of preventing it from occurring.

Where is raw water stored?

Are there any impurities in the water supply?

The water supply of home (municipality/bore) often has a lot of physical and chemical impurities, which can be observed by examination of water storage tank, having a lot of dirt in it. Sometime that dirt or particles can also be seen in water taps.

Why are there so many problems with raw water?

The biggest problem in raw water, with suspended solids in particular, is variation in the suspensions—suspended solids increase and decrease as the seasons change, wreaking havoc on water treatment plants that might be constantly changing their chemistry to maintain water clarity for their process.

What happens if you drink water with suspended impurities?

If consumed, suspended impurities in water if consumed can result in a range of medical ailments and illnesses. These include, but are not limited to: Cholera. Guinea worm disease. Typhoid. Legionella. Dysentery. Malaria – most commonly associated with mosquitoes and germs in contaminated water.

Why is iron a problem in raw water?

Iron in your raw water feed Typically not a problem in surface waters (as the oxygen in the air will oxidize it and form it into particles), iron becomes a problem in raw water, where it is generally dissolved. When the iron-contaminated water is drawn to the surface and used, it will oxidize and turn the water red.
