Drinking water, waste water, rainwater, groundwater, seawater, mineral water and distilled water are the most commonly known classifications. In addition to these, there are other differences, such as mineral water, osmosis water, pure water and ultrapure water.<\/p>\n\n\n\n<p>Let's start by mentioning \"living water\", which is currently booming in advertising. Some manufacturers advertise their systems with claims such as \"energized\", \"bio-energy\" or \"energy module\", which use \"programmed natural high-energy spring water information\" to restore the water's original freshness and vitality. However, they fail to provide any evidence of this that would stand up to purely scientific scrutiny and refer to the \"company secret\" (which could certainly be protected under patent law if it met the patent requirements ...).<\/p>\n\n\n\n<p>Incidentally, \"living water\" is a biblical quotation, for example in John 4:14 \"<strong>But whoever drinks of the water that I shall give him shall never thirst, but the water that I shall give him shall become in him a well of water springing up into everlasting life.<\/strong>\" or in John 7, 38 \"<strong>He who believes in me, as the Scripture has said, out of his body will flow rivers of living water<\/strong>n.\"<\/p>\n\n\n\n<p>Now to the differences between the various types of water available to us ...<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Regenwasser\"><\/span>Rainwater<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>Rainwater is already polluted when it rains down from the clouds by containing, in addition to dust particles, terrestrially generated, thermally (only decompose at temperatures above 400 \u00b0C) and chemically highly stable per- and polyfluorinated alkyl compounds (PFAS), many of which are not broken down but can be accumulated in human and animal tissue. <\/p>\n\n\n\n<p>In areas with PFAS-contaminated drinking water, statistically significant increases in diseases such as diabetes mellitus, cerebrovascular diseases, Alzheimer&#039;s disease, heart attack, as well as higher mortality rates are recorded.<\/p>\n\n\n\n<p>Since these compounds can only be incompletely broken down in sewage treatment plants, activated carbon is used for the long-chain PFAS.<\/p>\n\n\n\n<p>100 ng\/l PFAS contamination is stated to be ideal, while 300 ng\/l is considered \u201ctolerable for life\u201d.

The Baltic Sea has almost no salt at 0.2 \u2013 2 % compared to the Dead Sea at 28 %. It has an average conductivity of 56 mS\/cm.<\/p>\n\n\n\n<p>Seawater desalination plants reduce the salt content to a drinkable minimum with the addition of calcium hydrogen carbonate. Since desalination is a very energy-intensive process, the waste heat from nuclear power plants (including on ships, aircraft carriers or nuclear submarines), but also from systems powered by coal, gas or oil, is often used.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Destilliertes_Wasser\"><\/span>Distilled water<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>Distilled water is produced by evaporation and subsequent condensation, using a very high amount of energy. This largely removes salts, organic substances and microorganisms. The conductivity is only 0.5 - 5.5 \u00b5S\/cm (micro-Siemens per centimeter).<\/p>\n\n\n\n<p>Multi-distilled water is offered in double or triple distillates and stored in quartz or platinum containers because traces of silica are released from glass vessels during cooking and would thus contaminate the distillate.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Osmose-Wasser\"><\/span>Osmosis water<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>Water from the reverse osmosis system is filtered several times, down to 0.02 \u00b5m and achieves a conductivity of 1 \u2013 50 \u00b5S\/cm. <br>It is generally assumed that a reverse osmosis system achieves around 10 % of the conductance that is available on the input side.<br>Although reverse osmosis does not achieve the level of purity of distilled water, it is useful for producing drinking water in terms of hygiene.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Reinstwasser\"><\/span>Ultrapure water<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>Ultrapure water is produced via a strongly alkaline mixed bed system and used industrially, for example in the semiconductor industry.

This value provides information about the dissolved solids in the form of ions, such as metals, salts, minerals.<\/p>\n\n\n\n<p>The \u201cmeasuring devices\u201d that are often found in the \u201cscene\u201d in the range of around 20 \u2013 50 euros can at best be viewed as \u201cestimates\u201d. They only provide a rough estimate and show a trend.<\/p>\n\n\n\n<p>If you seriously want to have a reproducible and trustworthy measurement, you cannot avoid purchasing a device that is also available in a \u201ccalibrated\u201d version or an uncalibrated one.<br>Ultimately, a calibration certificate \u201conly\u201d states that the device delivers a value that is exactly identical to a reference device in a central range at a standardized temperature.<br>This reference is missing in an uncalibrated device. So it can show a value just below or above this reference value.<br>Temperature compensation is important, as the measurement must always be electronically adjusted based on 25 \u00b0C in order to correspond to the actual value and to comply with standardization.<\/p>\n\n\n\n<p>This means that two minimum criteria must be met: the function of conductivity and temperature measurement.
