And the clean water on family water purification instruments way
Abstract: this paper briefly introduces the simple family the way water purification and existing problems, and some family water purification instruments made simple analysis, focuses on the instructions of the advantages and disadvantages of all kinds of water purification instruments, and family the way water purification choice, and puts forward a feasible Suggestions.
Keywords: water treatment system in the water means blending
There is no something is perfect, for home water purification products, now has fewer people to go to discuss, after all, are already is sense, but recently found that some manufacturers still in not clear purpose of the production of household water purification equipment, on the basis of lower production cost the beaten track, so in the simple said once:

1, family water purification products series division

The current family water purification products in accordance with the water supply is divided into two series, and only for drinking belongs to the family small terminal drink (net) machine series, and meet the needs of the users for great volume of water purification instruments (equipment) belong to equipment series; Small terminal water purification series including family terminal, with water treatment filter material water dispenser, and a water purification function of water machine; Equipment series including can meet the requirements of the great volume of water purification equipment, villa group with small water station, and family pipeline water purifiers, etc.;

2, small terminal water purification way and applicability

Water dispenser and divided into membrane purification way and adsorption exchange ways, some on market reload activated carbon, maifanshi, nuwa stone, filter material straight water machine, it is to rely on adsorption, exchange, lumber mineralization way to improve water quality, but the loading of the filter material has a saturated limit, some products of ore mineral iodide separation is not stable, do not eliminate contain harmful material separation may be, filter material is a negative role saturated, in addition to the water containers (barrel) to empty the breath can cause bacteria enter the, can make the filter material become a hotbed of bacteria growth...

The small terminal membrane separation way water device, divided into molecular super LvJingHua and reverse osmosis except two kinds of salt purification, majority with activated carbon processing; For our country's most southern city, drinking water contaminants in more for microbiology indicators is unqualified, hardness is not high, completely can choose ultrafiltration products, both economical and water saving, and can keep the water was not much mineral content and trace elements; For the northern area, are drinking water with high hardness, GaoFu, high arsenic, such as poor water quality exceeds bid nitrate, and the secondary disinfection by-products and residual chlorine and network pollution situation, if ultrafiltration can't be a solution to, can choose reverse osmosis, but the reverse osmosis water utilization rate is low, the waste water is a big problem;

3, activated carbon produced by the role and insufficiency

No matter what way, mostly have activated carbon, in water purification system of activated carbon into front and rear; Because the membrane is organic material to make, in water for a long time, can cause a taste of water becomes poor, or activated carbon can improve texture, and lead active carbon adsorption commonly used to water of organic matter, residual chlorine, improve the film of the entrance of the water quality;

Ultrafiltration membrane hydrolysis effect more apparent than reverse osmosis, so ultrafiltration activated carbon front and rear is different, the lead activated carbon will eliminate residual chlorine to ultrafiltration, but on the terminal of the taste of water cannot guarantee (family is intermittent water, no continuous out of the water), if the rear, can guarantee that after filter taste, but can't eliminate residual chlorine and pollutants to the influence of the ultrafiltration, in addition, rear activated carbon filter carried by the miscellaneous bacteria can cause filter water exceeds bid after colony, and at the same time, stops for a long time, the more easily bacterium;

4, activated carbon filter change cycle of the problem

Many families buy water purification products in, be asked filter change frequency, manufacturers and sellers will give a rough period, but this story very responsible, to know that filter (especially activated carbon) is a saturated adsorption capacity limit; General activated carbon filter says on the 1500 GL, can deal with 1500 GL water, but the values are not absolute, active carbon adsorption capacity and paragraphs water quality, total water consumption, and use frequency is relevant, normal use water purifiers if long time don't ashore, it will have a variety of following the birth pollution, once again, enable, activated carbon filter should change, even when only a very short period of time...

5, meet the demand of the great volume of water purification system

Appear on the market in recent years a great volume of civil a water filter, more for ultrafiltration configuration, also have a few using reverse osmosis, general home users using ultrafiltration can meet in the family the way of service, the use of instruments to water the impact is not big (water to water pressure vessels for), clean water quality to bring water instruments protection, because in addition to the water filter the colloid silicon, heating scaling obtain alleviating, calcium magnesium separation is a few powder hot state;

In order to avoid membrane washing water produce fee, ultrafiltration strong water outlet for water quality is not high water appliances (such as ChongCe water tank), may at any time through the water to ultrafiltration flushing row thick, make the system of water in the environment often update;

Reverse osmosis system is due to atmospheric water way, exports are not allowed to have high back pressure, and produce a water yield less, must configuration terminal water containers, general airbag type pressure bucket, if be not pressure storage, need to be configured secondary pressurized water supply, but must pay attention to the secondary pollution, also reverse osmosis strong water also need to properly treated with use, avoid large amounts of water waste;

Great volume of water purification system can satisfy people for cooking, take a shower of the great volume of requirements, single from cooking, a bath USES for, ultrafiltration processing enough, with no configuration pressure, no energy consumption and noise, can be quiet work, reverse osmosis is otherwise, general private villas configuration 500 L/Hr system water system, high pressure pump and the amount of noise salinity water drain often is the main reason for the user to accept;

6, ultrafiltration practical advantages

The ultrafiltration more suitable for great volume of user use, because ultrafiltration water can keep TianRanShui to the human body function, in the process of no by-products harm, from the diet point, both the water purification, and keep the water to human body health benefits of minerals and trace elements, the role of the media in the human body to better play to the function of water and nutrition;

From the bath and personal hygiene speaking, water quality adverse effects on the body has the following four aspects:

Skin contact (wool stoma breathing), poor water quality easy cause itchy skin
