What is water turbidity? what is Iron tolerant in potable water?

Turbidity is the measure of relative clarity of a liquid. It is an optical characteristic of water and is an expression of the amount of light that is scattered by material in the water when a light is shined through the water sample.

Iron tolerance in potable water <1 PPM, to be precise0.3 PPM.

Turbidity is the amount of suspended matter in water/waste-water and is obtained by measuring its light scattering ability. It is also a measure ability of sunlight to pass through the water and the ability of water to disperse different materials disposed into it. A typical clear lake has a turbidity of about units while muddy water exceeds units. Turbidity is used to indicate water quality and filtration effectiveness (such as whether disease-causing organisms are present). Higher turbidity levels are often associated with higher levels of disease-causing microorganisms such as viruses, parasites and some bacteria. These organisms can cause symptoms such as nausea, cramps, diarrhea, and associated headaches. The allowable content of iron in potable water must only be0.3mg/L base on the world health organization standard. High levels of iron intake in human body can cause toxicity.

Turbidity can be interpreted as a measure of the relative clarity of water.

The drinking water standard for iron is0.3 milligrams per liter (mg/l)

Turbidity is a principal physical characteristic of water and is an expression of the optical property that causes light to be scattered and absorbed by particles and molecules rather than transmitted in straight lines through a water sample. It is caused by suspended matteror impurities that interfere with the clarity of the water. These impurities may include clay, silt, finely divided inorganic and organic matter, soluble colored organic compounds, and plankton and other microscopic organisms. Typical sources of turbidity in drinking water include the following:

• Waste discharges;
• Runoff from watersheds, especially those that are disturbed or eroding;
• Algae or aquatic weeds and products of their breakdown in water reservoirs, rivers, or lakes;
• Humic acids and other organic compounds resulting from decay of plants, leaves, etc. in water sources; and
• High iron concentrations which give waters a rust-red coloration (mainly in ground water and ground water under the direct influence of surface water).
• Air bubbles and particles from the treatment process (e.g., hydroxides, lime softening)

Simply stated, turbidity is the measure of relative clarity of a liquid. Clarity is important when producing drinking water for human consumption and in many manufacturing uses. Once considered as a mostly aesthetic characteristic of drinking water, significant evidence exists that controlling turbidity is a competent safeguard against pathogens in drinking water.

Water turbidity is300 and iron tolerant in portable water is2.5.

1. Turbidity is the cloudiness or haziness of a fluid caused by large numbers of individual particles that are generally invisible to the naked eye, similar to smoke in air. The measurement of turbidity is a key test of water quality. As per my knowledge iron tolerant in potable water is 200 μg/l.
