Domestic Water Treatment:
The domestic Water Treatments involves treatment for potable or drinking purpose. Taste. Odor. Hardness. Contamination. These are four of the most common reasons why people install water treatment systems in their home.
An activated carbon filter removes many volatile organic chemicals, some pesticides, radon gas, hydrogen sulfide, and mercury. It also reduces odor, color, and taste problems (such as residual chlorine). Water is filtered through carbon granules that trap contaminants. But infrequently maintained filters can result in higher concentrations of contaminants and can serve as a breeding ground for bacteria.
Units with volatile gas vents can remove some volatile organic chemicals as well. With distillation, water is evaporated, leaving impurities behind. The steam is then cooled and becomes distilled water. But the distillation process is slow and consumes a lot of energy, making it expensive. It also consumes large amounts of water if the coolant used in the distillation process is water. Distilled water can corrode materials such as iron and copper in plumbing systems.
Ultraviolet radiation removes bacteria and other microbiological contaminants. Water passes a special light bulb where ultraviolet radiation kills contaminants. However, this system may not work effectively in cloudy water or when the water flow is too fast. Also, unless the unit is equipped with a special meter, it is hard to know whether the system is doing the job.
