How Do Water Treatment Systems Work?
Toxic chemicals, bacteria, and heavy metals often pollute our natural sources exposing people to illnesses and in the long term put them at risk for such serious health conditions as cancer and liver damage. Today, just about every water source is contaminated so governments have to disinfect the water before they reach the people's faucets. However, chemicals used to clean water for human use can be harmful to human health. As well, governments determine certain level of specific contaminants that are allowed to be in the water which means drinking water is not pure and healthy. Whether or not any of these impurities are harmful depends on the nature and the amount of the impurities, the levels permitted for each, and the end use of the water. A good water filtration system is the only way to ensure the quality and safety of your drinking water.
Water treatment systems normally use one or a combination of the following methods: Disinfection methods (Ultraviolet Light, Chlorination, and more), Filtration such as activated carbon filters, Reverse Osmosis, Distillation, and Deionization (water softeners). Deionization involves the removal of dissolved substances in ionic form. The hard water is pushed through a tank containing an exchange resin. Sodium on the exchange resin replaces the hardness minerals. The system removes calcium, magnesium, iron, manganese and other heavy metals which is why it is also called demineralization.
Ultraviolet radiation (UV) involves the uses of low-pressure mercury arc lamps that produce ultraviolet light containing germicidal elements. The radiation kills or deactivates the pathogens. Bacteria are killed with relatively low amounts of radiation, but cysts and worms are not affected and viruses are more resistant. The water color and turbidity and can interfere with the transmitting of ultraviolet energy and may reduce efficiency.
Filtration systems include activated carbon filters, mechanical filters, neutralizing filters, and oxidizing filters. These systems are effective and an easy way to eliminate a variety of contaminants. Mechanical filters (microfiltration) remove suspended substances from water using a filter that captures the material such as organic material. Filters are normally screening material such as fiber, fabric, ceramic or another type of screening material. As well, mechanical filters can be cartridge units that are mounted on a tap, or even water tank units which treat an entire home water supply.
Activated carbon filters absorb impurities as they pass through a carbon cartridge. They are normally used to get rid of unpleasant odours, tastes, residual chlorine, and organic compounds. Carbon filters can also remove hazardous contaminants such as radon gas, dissolved organic chemicals, and trihalomethanes.
Reverse osmosis pressurizes and sends impure water through a semi-permeable membrane. The process removes about 90% of mineral and biological contaminants such as metals, salts, minerals, microorganisms, and other organic chemicals. Reverse osmosis, Deionization, and Distillation cause the direct removal of impurities from water.
Before buying a water treatment system, it is important to test your water to find out the type of treatment that you need. As well, there are water systems that contain technology from various water treatment methods thereby removing a whole host of contaminants. These types of water systems are popular as they produce very clean and great tasting drinking water.
