subject: Consideration While Choosing Water Treatment Devices [print this page] Drinking purified water is very essential for a safe and secured health and there are many water treatment devices available in the market to improve drinking water quality. But the decision as to which device is suitable for your house depends on the type of contaminants it removes. Before determining the water treatment method, it is necessary to get the water tested for coliform bacteria, pH, total dissolved solids, nitrates, hardness or iron and manganese before.
Some common water treatment devices and their functions:
Water softeners make use of a cation exchange process, which is regenerated with sodium chloride or potassium chloride, helping to reduce the hardness in water.
Activated carbon or charcoal filtration devices are the most useful devices to remove organic compounds which are often responsible for bad taste, odor, and dirty physical appearance. Also this activated carbon filters help to remove chlorine. These can be fitted to a faucet, or a pitcher such as a Brita.
Iron filters are another useful device. Iron or manganese in water does not cause any health hazard but they cause bad taste, staining and accumulation problems. Iron also causes reddish-brown staining of laundry, dishes, utensils, porcelain and also glassware. Certain deposits gather in pipelines, water heaters, water softeners and pressure tanks, which cause reduction in the available quantity of water and pressure of the water supply.
Reverse osmosis reduces the possibility of naturally occurring substances which give unappealing water and substances that have caused contamination in the water supply, for example nitrate, and sulfate, sodium and dissolved solids. Units of reverse osmosis along with carbon filters may help to reduce the man made chemicals like pesticides, dioxins and VOCs (volatile organic compounds).
The methods involved in improving the water quality include removing the source of contamination, repairing or drilling of a new well, connecting to a rural water supply, using bottled water which is an expensive option, or installing a water treatment device. You need to keep in mind the following considerations while purchasing a device:
Before investing, get the water carefully tested at a certified lab to correctly find out the concern.
Do take a copy of the results if a dealer offers tests.
Make sure that the system has been rated by the National Sanitation Foundation (NSF)
Ask the dealer about the replacement requirements and costs.
The water producing capability should be confirmed also how rapidly it will recharge.
Water softener should recharge on demand, or as indicated by the water quality.
Proper implementation of these suggestions and selection of appropriate water treatment devices can give you and your family a happy and secured life and investing in these devices is always a better option than investing in medicines to cure diseases caused by contaminated water.
