Choosing a water filter, you need at least in General terms, to know how it works, advantages, disadvantages and features of the device.
waterfilter waterpitcher filterswater purifiedcleaning waterfilter element
Made in the shape of a jug, from which the upper water tank by gravity through the filter and already cleaned, accumulates in the bottom of the container. Thanks to the filter element of activated carbon purifies water from mechanical impurities, pesticides and chlorine. Also removes color and odor of the water. There are filters with bactericidal modules and filter elements for reducing the water hardness.
The advantages of the pitcher filter are its low cost and ease of operation. To use filter pitcher no need water connection and perform any installation works. Enough to pour into the upper container of the water pitcher and wait until it will filter and will drain down.
The main disadvantages – low productivity and limited resource of the cartridge filter of 300 to 500 liters.
The principle of operation is similar to a pitcher filter is in the filtration of water by passing it through a carbon filter. If necessary, the filter is put directly on the faucet and open the water supply. From the nozzle enters the water, cleaned of rust, sand, chlorine, odor and turbidity.
For ease of use some filters-nozzles equipped with a diverter that allows you to let the water through the filter or around it.
The positive side of filter-tips is its low cost and ease of installation of the nozzle on the faucet. Of the minuses – all the same low productivity and limited resource of the filter element.
Flow bulb filter
Variants of this family of water filters very much. They can be installed next to the sink, and underneath, the number of flasks may vary from two to three. Pipe from filter connects directly to the tap and is driven by a separate tap. When installed under the sink on the kitchen counter displays a separate pipe with a faucet for supplying purified water.
The filtration system consists of a prefilter, carbon filter, water softener and obezzhelezivateli. Separate models are produced and disinfection of water using ultraviolet lamp and its treatment with ozone, silver ions, iodine and chlorine compounds. As a result of cleaning water that is fed from a flow bulb filter, completely safe and suitable for drinking: from removed mechanical impurities, chlorine, pesticides, it contains no pathogenic bacteria and salts of heavy metals.
Conus flow filters offer high performance and long service life cleaning cartridge (2,000 to 7,000 litres). Despite the high price of these filters, the cost of treating 1 liter of water from them is lower than pitcher filters and filters-nozzles.
reverse osmosis System
Is the most complicated and expensive device for water purification. The principle of operation is to use a reverse-osmosis membrane with a molecular size of 10-500 nm. In the process of passing water through a semi-permeable membrane is virtually complete (99%) purification from all impurities and dirt. Purified water is collected in a special holding tank, from where it is fed via an additional faucet to the consumer, and the remaining water of detainees impurities are derived in the sewer.
Water purified using reverse osmosis systems, for their quality is comparable with melt water. Often such systems are used for seawater desalination.
High performance, large (up to 10000 l) resource filters and membranes, impeccable quality of cleaning has done the reverse osmosis system is the undisputed leader in water treatment systems. The only thing that keeps them from mass distribution in the home – a very high cost.Let the water in your house will always be crystal clear and healthy!
Be always healthy!
