Hereinafter, a scale inhibiting activated carbon filter element 100 and a water treatment system 200 according to an embodiment of the present invention will be described with reference to the accompanying drawings. It is understood that the scale inhibiting activated carbon filter element 100 according to the embodiment of the present invention is not limited to be applied to the water treatment system 200 having the structure shown in fig. 2, and may be applied to other structures, as will be readily understood by those skilled in the art.

Specifically, in the related art, in the activated carbon filter element and the reverse osmosis system formed by the activated carbon filter element, the activated carbon filter element has no scale inhibition function, cannot inhibit calcium and magnesium ions in tap water from scaling and precipitating, and cannot protect the reverse osmosis membrane and the electromagnetic valve from scaling, so that the reverse osmosis filter element is easy to be polluted and blocked, and the wastewater electromagnetic valve is scaled and blocked, so that the whole water system cannot run. In some water systems with scale inhibition function, a scale inhibition device needs to be arranged independently, so that the number of parts is increased, and the cost is increased.

In addition, the scale inhibition activated carbon filter element 100 according to the embodiment of the invention is also specially designed in terms of the requirements of proportioning and materials. The activated carbon particles 21 and the granular scale inhibiting material 22 with specific sizes and specific proportions are adopted, so that the filtering area can be increased, the filtering material 20 is not easy to wash away with water, the size of the activated carbon particles 21 is smaller than that of the scale inhibiting filtering material 22, the activated carbon particles 21 can be filled in gaps of the scale inhibiting filtering material 22, the filtering effect is easier to ensure, and meanwhile, the scale inhibiting filtering material 22 is easy to contact with water to exert scale inhibiting capacity.

In some embodiments of the present invention, the mesh number of the activated carbon particles may be 20-30 meshes, for example, 22 meshes, 25 meshes, 278 meshes, etc., the particle size of the scale inhibiting filter material may be 3.5mm, and the ratio of the activated carbon particles to the scale inhibiting filter material is: 55 parts of activated carbon particles and 45 parts of scale inhibiting filter material.

As shown in fig. 2, a water treatment system 200 according to an embodiment of the invention may include a scale inhibiting activated carbon filter element 100 according to an embodiment of the invention. With continued reference to FIG. 2, the water treatment system may optionally further comprise: the scale inhibition activated carbon filter comprises a front filter element 210, a water inlet valve 220, a booster pump 230 and a reverse osmosis filter element 240, wherein the front filter element 210 is arranged in front of the scale inhibition activated carbon filter element 100, the water inlet valve 220 is arranged behind the scale inhibition activated carbon filter element 100, that is, the scale inhibition activated carbon filter element 100 is arranged between the front filter element 210 and the water inlet valve 220.

In the above structure, the scale-inhibiting activated carbon filter element 100 is disposed behind the front filter element 210 and in front of the water inlet valve 220 in the water flow direction, so that impurities in water can be reduced from entering the scale-inhibiting activated carbon filter element 100, and meanwhile, the scale formation problem in the water inlet valve 220, the booster pump 230 and the reverse osmosis filter element 240 can be reduced, which is particularly beneficial to prolonging the service life of the reverse osmosis filter element 240. Research shows that the service life of the reverse osmosis filter element 240 can be prolonged by more than 100% by adopting the scale-inhibiting activated carbon filter element 100.

This water treatment system 200 can constitute backward flow reverse osmosis system, can realize the reverse osmosis filtration of concentrated water, can reduce final waste water volume, promotes water treatment system 200 to the rate of recovery of water. In practical use, the concentrated water can be filtered once or many times by controlling the open and close states of the wastewater return valve 253 and the flushing solenoid valve 244. For example, in a place with a high water quality, the concentrated water may be discharged after being circulated once, and in some places with a high water quality, the concentrated water may be discharged after being filtered twice or three times. In this system, the life of the reverse osmosis cartridge 240 may be increased.
As shown in fig. 2, the water treatment system 200 may optionally further include a control valve 254, and the control valve 254 may be disposed in the concentrate water branch 243 between the branch inlet 251 and the concentrate water outlet 242. Therefore, the on-off of the return branch 25 and the concentrated water branch 24 can be controlled by one valve body, namely the control valve 254, and when a certain branch needs to be conducted independently, the control can be carried out by the water inlet valve 220 or the flushing electromagnetic valve 244, so that the control is more flexible.

Alternatively, the control valve 254, the water inlet valve 220, and the waste water return valve 253 may be solenoid valves, respectively. The electromagnetic valve can realize automatic control, so that the controllability of the whole water treatment system 200 is improved, and the automation degree is higher.
As shown in fig. 2, the front filter element 210 may be a PP cotton filter element, which has good filtering effect and is easily available. The water treatment system 200 may further include a post-activated carbon filter cartridge 260, the post-activated carbon filter cartridge 260 being disposed behind the reverse osmosis filter cartridge 240, and the post-activated carbon filter cartridge 260 being in communication with the permeate outlet 241.
