Pranam
1 Migration is the way of human life. Bangalore in T N and vice versa is
for profession and settlement. Software attracts men to Bangalore.
Construction attracts to TN. Electronics pull people to AP. Estates do
attract to Kerala. Mines to Bihar. Business to Mumbai. BATA to Calcutta.
Old age retirement homes to Coimbatore.
BSNL shift is done in 10 minutes online; only refund takes some time;
but asking an insinuating question after 3 years appears to my tax mind as
an alibi. Why wet kerchief.
Ironing is in vogue in the history; kings did all through the fire
boxes; and there is a place (Johannesburg?) in South Africa, where Indians
live in large numbers, especially Guj; and there sun shine is good so
cloths are dried outside; but there is a problem of micro-bugs, harming the
health of the residents, entering through the dried clothes; so they always
iron all dried clothes before they wear.
Dinosaur brought me to think that that period is deciphered and any
grandchildren of Indian origin in USA, will narrate a lot on that; and all
flora, fauna and animals and life were taller than we see today; and age
factors were also totally different; Valmiki describes Rama as AJANU BHAHU
SUSIR: SULALATA SUVIKRAMA: AS 8FEET TALL WITH THE LONG HANDS; so Rama
period could have been the dinosaur period may be; if so our scriptures
chaturyuga theory would also fit in. Bottled business started in USA as
early as 1894 by coa cola; Indian bottling was very late; and water in the
bottle was only later than the AAVIN and milk products in India in Bottles
once.
TDS total dissolved solids
2 TDS or Total Dissolved Solid mainly refers to any kind of organic
or inorganic matter that is found in water. In drinking water TDS,
inorganic matter consists of dissolved calcium, magnesium, potassium,
sodium, bicarbonates, chlorides, and sulfates.. The water TDS level which
is considered more suitable and acceptable for consumption is below 300
PPM.
The TDS level for drinking water as per WHO is as follows:
- Less than 300 - Excellent
- 300-600 - Good
- 600-900 - Fair
- 900-1200 - Poor
- More than 1200 - Unacceptable
However, TDS levels more than 300ppm impact the taste of drinking water and
as it keeps increasing, water becomes even less palatable.
You can measure TDS at home using a TDS meter. It is a hand-held
device that indicates Total Dissolved Solids present in the water.
Dissolved solids like minerals and salts can increase the conductivity of a
solution and the meter measures this conductivity and estimates the TDS
from that reading.
Reverse Osmosis or RO water purification is the most effective way
of reducing TDS in water. The dissolved solids like calcium, magnesium,
sodium, and potassium cations and carbonate, hydrogen carbonate, chloride,
sulphate, etc get trapped in the fine RO membrane, enabling only purified
and sweet tasting drinking water to pass through it.
Testing the water is a great way to check the quality of water
that you receive and use for different purposes. Here are some reasons you
need to measure TDS in water.
- *Taste-* High levels of TDS in water affects the taste of your
drinking water. Your water may taste bitter, salty or sulfuric depending on
the type of dissolved solids present in water.
- *Health Purposes-* Water with high TDS is completely safe to drink.
However, some substances such as lead, or copper can lead to health hazards.
- *Maintenance of Filters-* Water filtration systems are affected by a
high level of TDS. Testing the water purifier systems regularly will ensure
that the filters work properly
- *Cooking-* Though high TDS doesn’t affect health, it can alter the
taste of your food.
- *Cleaning-* High TDS in water leaves ugly spots on your utensils. This
type of water also fades the color of your clothes, lead to a buildup in
your sinks, tubs, and faucets.
TDS present in water is not a measure of any single
contaminant and so is generally not regulated as a health issue by many
government agencies. A high TDS level, however, can affect the taste and
odour of water. The Environmental Protection Agency in the US has set
the *maximum
recommended level* of 500 milligrams per litre (mg/L).
he table mentioned below provides a permissible range of *TDS
in drinking water* and reasons for why the TDS level mentioned in water is
not acceptable for drinking:
TDS Level (Milligram/Litre)
Remarks
Less than 50
Unacceptable as it lacks essential minerals
50-150
Acceptable for drinking. The TDS level is ideal for areas where the water
polluted by sewage or industrial waste
150-250
Good. The water is ideal for people with cardiovascular disease
250-350
Good. The water is ideal for people with cardiovascular disease
350-500
Fairly acceptable
500-900
Less acceptable
900-1200
Least acceptable. Avoid drinking water which has a TDS level of 900
1200-2000
Water is not acceptable for drinking.
Above 2000
Unacceptable
According to the Bureau of Indian Standards (BIS), the upper limit of TDS
level in water is 500 ppm. The TDS level
<https://www.who.int/water_sanitation_health/dwq/chemicals/tds.pdf> recommended
by WHO, however, is 300 ppm.
