What is TDS?

TDS in drinking-water originate from natural sources, sewage, urban run-off, industrial wastewater, and chemicals used in the water treatment process, and the nature of the piping or hardware used to convey the water, i.e., the plumbing.

What makes water impure? TDS or Total Dissolved Solids can be defined as the combined content of all inorganic and organic substances contained in a liquid which are present in a molecular, ionized or micro-granular (colloidal sol) suspended form. Our water is mostly saturated with chlorine, nitrates, aluminum, mercury, lead, fluorine, arsenic, cadium and calcium to name a few. TDS includes all these contaminants, but it also includes minerals like magnesium, bhoor and potassium, minerals that you body can use. Unfortunately, most of the salts in water are a health hazard. This means that the human body cannot use these particles at all. The result of consuming raw tap water daily over a period of time is the hardening of arteries, arthritis, cancer, tiredness, Alzheimer’s disease, kidney stones, gallstones ext. Although numerous chemicals are added at the purification plants in an attempt to get rid of bacteria and viruses in water, metallic poisons contaminates that water even further by pipelines which the water travel through. It is a dangerous cycle that affects people’s health and lives daily. But what are the TDS readings in South Africa?
Well, it depends where you go!! Areas like the Western-Cape, Eastern-Cape, Mpumalanga, Limpopo and even Gauteng's water supply is of deterioration quality.
I have tested water with TDS readings of between 100 and 2000!
One thing that one should understand about TDS is that it does not only measure undesirable contaminants. It also measures desirable minerals that your body needs. If you are interested to know EXACTLY what is lurking within you raw tap water then you need to get it tested by the WNNR.

The conclusion:
TDS is just a measure of the TOTAL amount of salts/particles within your water.
Research has shown unfortunately that high TDS readings within South Africa are the cause of undesirable particles.

You discuss TDS as a bad thing in your blog but at the end you mention that it also contains minerals that we need, surely this would mean we should not remove them?
Is there not a system that removes contaminants but leaves the minerals in the water?
The world health organization standards state that the minimum TDS should not be below 20 and the maximum should not be above 500, surely this would mean this system would not be needed in 90% of SA water?
If this system is truely going green does it waste water when producing pure water and is if so at what ratio?
