Ancient Persian clock in Qanats of Gonabad Zibad According to Callisthenesthe Persians were using water clocks in BC to ensure a just and exact distribution of water from qanats to their shareholders for agricultural irrigation. The use of water clocks in Iranespecially in Zibaddates back to BC. The water clocks used in Iran were one of the most practical ancient tools for timing the yearly calendar.
Monday-Friday What are nitrates? Nitrates NO3 are an essential source of nitrogen N for plants. When nitrogen fertilizers are used to enrich soils, nitrates may be carried by rain, irrigation and other surface waters through the soil into ground water. Human and animal wastes can also contribute to nitrate contamination of ground water.
In Benton and Franklin Counties, agricultural practices have been linked to elevated levels of nitrates in drinking water. Although any well can become contaminated by nitrates, shallow, poorly constructed, or improperly located wells are more susceptible to contamination.
Nitrate levels in drinking water can also be an indicator of overall water quality.
Elevated nitrate levels may suggest the possible presence of other contaminants such as disease-causing organisms, pesticides, or other Simple water level indicator and organic compounds that could cause health problems.
Who is at risk from high nitrates in drinking water?
In addition, inspect surrounding areas within a foot radius of the well for sources of pollution such as garbage, animal pens, barns and especially agricultural areas where nitrogen fertilizers can contaminate ground water (this includes your home garden). Nov 10, · Basically the unit is made up of various sensors acting as a ashio-midori.com me explain in a simple way. What happens is when you turn on you water pump, the water starts to get pumped from your underground reservoir or from your underground water supply from the pipes to your water tank. Float and Board Type Level Indicator Our range of products include tank float level indicators, fluid level indicator, fuel tank level indicators, float type level indicator, tank liquid level indicator and water level indicator.
Nitrate levels at or above this level have been known to cause a potentially fatal blood disorder in infants under six months of age called methemoglobinemia or "blue-baby" syndrome; in which there is a reduction in the oxygen-carrying capacity of blood. The symptoms of blue-baby syndrome can be subtle and often confused with other illnesses.
In more serious cases, infants will start to show obvious symptoms of cyanosis: It is difficult to determine the true incidence of blue-baby syndrome in Washington State because it is not a reportable disease.
Others at risk from excess nitrates in drinking water are: Pregnant women Individuals with reduced gastric acidity, and Individuals with a hereditary lack of methemoglobin reductase. In addition, some health studies have suggested that exposure to high levels of nitrates could lead to some forms of cancer, but results are inconclusive Testing recommendations: The only way to know if your drinking water is contaminated with nitrates is to have it tested.
If you own a single family domestic well, it is recommended that you test your water every three years for nitrates; more often if you live in an area with a history of high nitrate levels or if someone in your home is at risk from nitrate contamination. What to do if you have high nitrates in your drinking water: If your drinking water sample tested above the MCL for nitrates and you or someone else in your home is at risk of developing health problems due to high nitrates, it is recommended that you do not drink the water.
Find a safe, alternative water supply until you decide on a more permanent solution.
There is no simple way to remove all nitrates from your water.Fluidyne Instruments Pvt Ltd - Engaged in exporting and manufacturing of magnetic level indicators, liquid level indicators, magnetic level indicator, level gauges, liquid level indicator, magnetic liquid level indicators, valves, magnetic liquid level indicator, level indicators, level indicator, reflex gauges, transparent gauges, glass gauges, magnetic level indicator, remote level.
pH indicators. Certain dyes change colour depending on whether they are in an acid solution or an alkaline solution. pH indicator is a chemical compound added in small amounts to a solution so the pH (acidity or basicity) of the solution can be seen.
The pH indicator is a chemical detector for hydronium ions (H 3 O +) or hydrogen ions (H +). Normally, the indicator . So here is a simple and handy DIY that will guide you to make a circuit which will detect the water level and will raise an alarm upon getting the water tank full or a preset level.
This simple transistor based water level indicator circuit is very useful to indicate the water levels in a tank.
The oldest water clock of which there is physical evidence dates to c.
BCE, during the reign of Amenhotep III where it was used in the Temple of Amen-Re at Karnak. The oldest documentation of the water clock is the tomb inscription of the 16th century BCE Egyptian court official Amenemhet, which identifies him as its inventor.
