About water
Water is one of the most aggressive solvents known. Called the "universal solvent" water will, to a greater or lesser extent, dissolve virtually everything to which it is exposed. Water dissolves the quantity of material available until the solution reaches saturation, the point at which no higher level of material can be dissolved.
Impurities found in water include atmospheric gases, minerals, organic materials (some naturally-occurring, others man-made) plus any materials used to transport or store water. The hydrologic cycle (Figure 1) illustrates the process of contamination and natural purification.
Contamination in Water:
There are three main groups of contamination in water:
1. Metals such as lead, mercury, aluminium, arsenic and cadmium can, even at very low levels, cause diseases such as cancer, brain disorders, severe stomach disorders or even death.
The CW42® removes or controls the levels of all these metals.
2. Some contaminants such as herbicides, pesticides, trihalomethanes and others compounds caused by the reaction between chlorine and organic matter in water are considered to be extremely harmful and some are even carcinogenic. Many of these compounds are only now being recognised as harmful.
The CW42® completely removes these compounds.
3. Bacteria, such as E. coli and Salmonella, and parasites, such as Cryptosporidium and Giardia, can cause severe illness or even death. Some of these, particularly the parasites, cannot be controlled using chlorine disinfection.
The CW42® provides complete protection from such bacterial and protozoan pathogens.
Water
Water covers 70% of earth's surface but only 0,1% is available as drinking water. Clean and safe water is a fundamental need in society. Two thirds of the world's population do not have water fit for human consumption. More than 5 million children under the age of 5 die from waterborne disease every year. The human body made up of more than 60% water and we need more than 3,4 litres of fresh water every day.
Drinking water – the essentials:
Water must be:
- Available
- Free of disease
- Free of poison
Water should be:
- Free of unpleasant odour
- Free of colour or cloudiness
- Free of additivess
- Fresh tasting
Water should not be:
- “Ultra” pure, i.e. without taste and healthy minerals.
The major contaminants in water are:
- Bacteria and cysts
- Heavy metals
- Industrial chemicals
- Agricultural chemicals
The health effects from contaminated tap water are:
- Diarrohea or even fatal gastro-intestial disease
- Alzheimer's disease/development of the brain
- Cancer
- Impaired reproductive ability
- Why more and more people drink bottled water?
- Tastes better than tap water
- Movement towards healthier living and diet
- Concern about artificial additivess in soft drinks and impurities in tap water
