The influence of sodium ion high in softener

The influence of sodium ion high in softener The use of the softener not only solves the scaling problem of the hardness ions (calcium and magnesium ions) in the water pipe and the metal surface of the wading equipment installed on the water pipe, but also ensures the use effect of the equipment, prolongs the service life and reduces the use cost More importantly, the scaling situation is solved, and at the same time, the scale (bacteria inside and reproduction) is avoided to the water quality Serious and imperceptible pollution Using the general traditional softener, users can not avoid the fact that: first, the softener removes most of the calcium and magnesium ions that are beneficial to human body; second, the sodium ions that are harmful to human body are greatly increased in the soft water (according to the principle of ion exchange, the increase of sodium ions in the soft water is equal to the removal of calcium and magnesium Fangfeng); 3、 Due to the increase of sodium ions, the soft water has a great increase in corrosiveness to water pipes and wading equipment Is sodium ion of water softener harmful to human body? About sodium ion of water softener, many people have doubts about it In fact, the increase of sodium ion has little effect on human body, because its content is very small In the operation of the softener, the exchange ratio of calcium, magnesium and sodium should be 1:0.46 equivalent According to the Beijing water hardness of 300 ppm, 140 mg sodium is added to the water, and 240 mg sodium is added for each person to drink 2 liters of water every day However, China advocates that the per capita social sodium content of Zui should not exceed 6000 mg per day, and the proportion is less than 5%, which is not enough to destroy the diet structure How can it cause harm to the human body In terms of controlling the intake of sodium, Chinese people's diet is already a kind of high sodium The amount of sodium we usually take from vegetables is much higher than the content of healthy diet standards in developed countries, so it is more helpful to improve the type of food and drink In addition, many foods or drinks that we don't notice at all also contain a lot of sodium, such as juice and coke, but the human body is short of sodium It's even more terrible The remedy measures are: *, the household water pipeline and the drinking water pipeline must be separated to ensure that the calcium and magnesium ions in the drinking water are not reduced and the sodium ions are not increased; Second, an anti-corrosion feeder is installed at the downstream of the softener to ensure that the domestic water with increased corrosivity will not damage the metal surface of metal pipes and wading equipment, but whether the dosing agent is toxic to human body has not been determined For a water softener, the control system, valve head and resin constitute the core of the quality of a domestic water softener, of which the control system is the core, equivalent to the headquarters of the water softener, followed by the valve head and resin The resin tank for industrial use is a single-layer resin tank, and the requirements for civil use are double-layer (single-layer FRP tank has peculiar smell), the inner layer is ABS (food grade), Zui and steel wire mesh reinforcement Control system (the core of the water softener) * generation: in 1925, the mechanical clocking controller was invented It is Zui original and simple It determines the time by clocking It controls the water softener like the old mechanical clock In a certain time, it cleans the original working procedures The second generation: electronic time type and flow type controllers In the 1960s and 1970s, electronic time type flow type controllers were invented Time type: the reduction cleaning time can be set on the control panel Whether water is used or not, the machine will set the reduction cleaning time Whether water is used or not, the machine will restore cleaning at the set time, or sometimes there is too much water, which will not be cleaned in time Flow type: periodic flow can be set on the control panel When the set flow is used, the machine will be restored for cleaning Disadvantages: the periodic flow cannot be set scientifically, resulting in a great waste of salt and water The third generation: intelligent computer board control system the computer board of the water softener stores various parameters, including the valve head parameters of resin (exchange capacity, exchange speed, mechanical strength), valve head parameters, parameters of the salt suction system, etc., which can be accurately grasped by the manufacturer's long-term practice In the actual use process, users only need to input the hardness of the water in the computer board, the control system of the water softener will automatically calculate the periodic water consumption, and the reduction time, to achieve Zui's best salt and water saving mode In practical application, it can save more than 50% of water and salt The intelligent computer board can automatically alarm when salt tank is short of salt It has language selection of 13 countries, memory function of customer water consumption, display of remaining drinking water, statistics of water consumption and night light in salt tank A good computer board can control that there is no water in the salt tank, and only water will enter when reducing The intelligent system also has dual reductant mode (NaCl and KCl) It can also be set to time mode in specific environment, and even have remote monitoring technology The quality of resin mainly lies in exchange capacity, exchange speed and mechanical strength The theoretical service life of resin is * and can reach 40-50 years Resin Zui is afraid of iron poisoning (i.e iron pollution) and active chlorine poisoning In China, due to the use of bleaching powder, chlorine and iron pipe, Zui good resin can be used for about 20 years, and the difference is only 2-3 years Resin is also divided into food grade and industrial grade It can only be used in civil drinking water after passing NSF test in the United States.
