PURIFYING WATER OPTIONS
- Carbon Filtration systems – typically use carbon to attract contaminants to adhere to the porous surface of the carbon substance. Some of the sources of carbon are coconut, charcoal and ceramics This process helps removes odour, taste and particles in the water. There are many different filtration systems available and it seems the surest bet is the multi-stage filtration systems that use a range of different mediums to ensure that most contaminants are dealt with while maintaining mineral content.Contaminants removed by filtration are lead, PCBs, chlorine byproducts (chloramines and trihalomethanes), certain parasites, radon, pesticides and herbicides, the gasoline additive MTBE, the dry-cleaning solvent trichloroethylene, some volatile organic compounds, some levels of bacteria (such as Cryptosporidium and Giardia) and a small number of pharmaceuticals.
- Reverse osmosis – is a process where water is passed through a thin membrane under high pressure. This process requires a lot of energy and a large amount of water is wasted during the process. This system does remove a wide range of contaminants but molecules that are smaller then water molecules can not be filtered as they are small enough to pass through the membrane, these include volatile synthetic chemicals. Some Reverse Osmosis systems can purify the water 100% but unfortunately this also robs the water of minerals as well. Minerals in water are required for its electrolyte influence in order for the water to be carried across the cell membranes in the body.Contaminants removed by Reverse Osmosis are perchlorate, sulfates, fluoride, industrial chemicals, heavy metals (including lead), chlorine byproducts, chlorides (which make water taste salty) and pharmaceuticals.
- The Distillation process – involves boiling the water and then collecting the condensing water which has been purified to great extent. But again, this robs the water of necessary minerals. Distillation is also energy – intensive.Contaminants removed by distillation are heavy metals (including lead), particles, total dissolved solids, microbes, fluoride, lead and mercury.
- The therapeutic actions of Ionizing water filters aim to promote health and minimise diseases caused by the alkaline/ acid pH balance and dehydration. Ionized water contains Hydroxyl ions (these are water molecules with an extra electron) which are found in vitamins such as Vitamins A, C and E. These potent antioxidants are free radical scavengers (reduce inflammation) thereby increasing hydration and oxygenation.Many water filters also look at the correlation between health and our bodies’ overall state of relative acidity and alkalinity. Every cell in our bodies is affected by the pH level, too much acid creates an oxidation effect and causes cell destruction (cancer, arthritis, kidney diseases), whereas an alkaline environment is sustaining for the health of all bodily systems. The key for maintaining a healthy pH is to keep it above 7.1 on the pH meter.The ionizing water filters are recommended by and for individuals who have chronic debilitating health conditions who require to increase their cellular health and vitality by ensuring proper hydration, pH balance, elimination of heavy metals and antioxidant status.
An international standard called The NSF (national sanitation foundation) International provides a range of certifications for filtration products.
- NSF 42 covers aesthetic effects such as chlorine, taste, odour and particles.
- NSF 53 covers health effects such as cysts (giardia, cryptosporidium), a range of organic chemicals (such as THM and pesticides) and heavy metals.
