TDS in drinking water

TDS in drinking water - How many times do you drink water? Do you follow the recommendation for drinking at least 8 glasses of fresh water daily? Do not you have any questions what inside of water? Why drinking water can make you keep healthy? Well, it is important for you to know what you take daily.

The water contains of minerals. The minerals are commonly called TDS. If you want to get the best advantages from drinking water, you need not know about the standard level of TDS in drinking water.

TDS or Total Dissolved Solids influences the water quality. If the level is low, it will be not good for the healthy. TDS itself includes minerals, salts, metals, cations and anions. The good water is the water with TDS level not more than 500 ppm. If the TDS is more than 500 ppm, it will be harmful to be consumed. It is important to test the water whether it has high TDS or not. The pure water is colorless, tasteless and odorless.

If you find out that the drinking water supply you have tastes salty or bitter and also smells not good, you can’t consume it. It is like an alert that the water has high TDS. To test the TDS in drinking water, you can use the TDS meter device. It is not difficult to find this TDS tester device. You can simply make the shopping online through the internet.

There are many advantages you can get by drinking water. If you want to have the smooth and healthy skin, the water can works as natural moisturizer inside out. Water also can be used to press the appetite. It is good to lose the weight. Are you sure that the drinking water you take daily is kept its quality? That is why you need to know about the level of TDS in drinking water before you consume it.

Caffeine, Beneficial or Toxic?

Caffeine is a type of alkaloid found naturally in coffee beans, tea leaves, leaves of cashew, kola seeds, cocoa beans, and some beverages. Caffeine has a molecular weight of 194.19 with a chemical formula C₈H₁₀N₈O₂ and pH 9.6 (1% caffeine solution in water). Scientifically, the direct effect of caffeine on health is not actually exist, but that there is no immediate effects such as stimulating the respiratory and heart, and give side effects such as anxiety (neuroses), could not sleep (insomnia), and heart rate did not uniform ( tachycardia).

From some literature, it is known that coffee and tea contain caffeine than many other crops, because coffee and tea plants produce coffee beans and tea leaves very quickly, while the destruction is very slow. Here is the caffeine content in some products:

Products.	Caffeine content
A Cup Of Coffee	85 mg
A cup of tea	35 mg
A bottle of Coco-Cola	35 mg
Energy drinks	50 mg
Instant Coffee	2.8 – 5.0%
Mocca Coffee (raw)	1.08%
Mocca Coffee (Roasted)	0.82%
Robusta Coffee Java	1.48%
Arabica Coffee	1.16%
Coffee Liberika (raw)	1.59%
Coffee Liberika (Roasted)	2.19%

According to the Journal of the American Chemical Society, most coffee is made with low caffeine content is made with a chemical solution that can absorb caffeine from the seeds of the chemical. Or can also use the technique of "Swiss Water Process" is using hot water and steam to separate the caffeine from coffee beans. Also currently being investigated utilization of biotechnology for the destruction of the caffeine in coffee plants, one of which is the use of bacteria that is paired with theophylline, are compounds produced to destroy the caffeine in coffee and tea plants. It is expected that these bacteria can destroy the caffeine quickly, but keep the natural taste of coffee.

Everyone has different levels of sensitivity to caffeine. Some sensitivity to the effects of caffeine on pregnant mothers have been disclosed, which can cause birth defects. Research on humans and animals has not been conclusive results; whether it is true with normal daily consumption can cause birth defects. However because of uncertainty in human studies and has been a clear proof that some babies with disabilities occurred in animal studies, it may be advisable for women who are pregnant to reduce the consumption of caffeine per day.

Likewise also with the consumption of energy drinks (like Red Bull, M-150, and similar products). People may be attracted by its name and drink it to generate power. But it must be known to drink energy drinks are different from the energy source.

A food worth mentioning a particular source of nutrients when nutrients which claimed at least 10% of the recommended nutritional intake, per serving size. So a beverage product can be referred to as an energy source when in a single serving size contains at least 250-280 kcal. As an illustration of energy sufficiency adult men aged 20-45 years is 2,800 kcal / day, while the age of 46-59 years was 2500 kcal / day. While the contribution of energy drinks to energy needs, particularly adult males range from 7-15% when consumed 2-3 times a day or about 100-112 kcal of energy content for a single serving size (150 ml / bottle). From these calculations is known that energy drinks are not included in class beverages energy sources.

If the view of the composition, hence the need to be aware of energy drinks is caffeine. Mengutif some research results, the dose of 100-150 mg caffeine is amam limit human consumption, and given effect at this dose is to increase mental activity that makes people always awake, so the recommended dosage of consumption of energy drinks manufacturer is 2-3 times or equivalent with 100-150 mg of caffeine a day. It is actually at risk, especially if consumption of energy drinks are accompanied by drinking coffee.

Consumption of coffee / tea and energy drinks for the people of Indonesia, as has become tradition-rooted and difficult to abandon. For one thing, caffeine is a compound useful for humans, which has provided many advantages, especially to boost the power of concentration and increase pleasure in consuming a beverage. But on the other hand, caffeine is also known to be toxic compounds, which may disturb human health and the offspring. Now living on the wisdom from the man himself for not consume to excess. Would not an excess is always not good

Water Quality Monitoring : Biochemical Oxygen Demand

When organic matter decomposes, microorganisms (such as bacteria and fungi) feed upon it and eventually it becomes oxidized (combined with oxygen). Biochemical oxygen demand is a measure of the quantity of oxygen used by these microorganisms in the aerobic oxidation of organic matter.

When aquatic plants die, aerobic bacteria feed upon them and nutrients, such as nitrates and phosphates, are released into the body of water, stimulating plant growth. Eventually, more plant growth leads to more plant decay. Nutrients can be a prime contributor to high biochemical oxygen demand in rivers.

Impounded rivers also collect organic wastes from upriver that settle in the quieter water. The bacteria that feed on this organic waste consume oxygen. With much plant growth, the percentage of saturation (dissolved oxygen) often falls below 50 percent. Large daily fluctuations in dissolved oxygen levels are characteristic of bodies of water with extensive plant growth. Dissolved oxygen levels rise from morning through the afternoon as a result of photosynthesis, reaching a peak in the late afternoon. Photosynthesis stops at night, but plants and animals continue to respire and consume oxygen. As a result, dissolved oxygen levels fall to a low point just before dawn.

In rivers with high BOD levels, aerobic bacteria consume much of the available dissolved oxygen, robbing other aquatic organisms of the oxygen they need to live. Organisms that are more tolerant of lower dissolved oxygen levels may appear and become numerous, such as carp, midge larvae and sewage worms. Organisms that are intolerant of low oxygen levels, such as caddisfly larvae and mayfly and stonefly nymphs, will not survive. As organic pollution increases, the ecologically stable and complex relationships present in waters containing a high diversity of organisms is replaced by a low diversity of pollution-tolerant organisms with increasing populations.

Why is the biochemical oxygen demand in water so high?

Check out your local watershed - can you find organic matter (such as leaves) entering the lake or river from swamps, bogs or vegetation in the watershed?

What is the difference between point source and nonpoint source pollution?

Are there any pulp or paper mills, meat-packing plants, food processing industries or wastewater treatment plants on your local river?

If you live in a city or suburb - do you have a separate or combined sewer system? Check it out with your local government!

If you live in a rural setting - do you have septic systems near the river or lake? Are these systems properly maintained?

Can you find any cattle feedlots, dairies or barnyards in the watershed? Is the waste from these feedlots properly contained?

What is the cause(s) of your problem? What did you find that led you to this conclusion?
