Activated carbon filter structure: in the pressure vessel filled with activated carbon filter media, the particle size of 0.8-2.0mm, the use of physical adsorption of activated carbon to remove organic matter, colloids, and some heavy metal ions, especially in the water, and to remove organic matter, colloids, and heavy metal ions. The physical adsorption effect of activated carbon is used to remove organic matter, colloids and some heavy metal ions in water, especially the colorful substances in water. At the same time, activated carbon can effectively adsorb residual chlorine in water to reduce the content of residual chlorine in tap water and improve the taste of water.
The water softener is the use of cation exchange resin to remove the hardness of water in a class of water processor.
When the calcium and magnesium ions in the water is relatively high, the water hardness is relatively high. High hardness of water in the heating process is easy to scale, the formation of scale wrapped around the outside of the heating pipe, resulting in heat conduction is not smooth, making the heating efficiency is low, serious will also cause the heating pipe burst, thus triggering safety accidents; high hardness of water in the washing with the detergent will neutralize the detergent, resulting in detergent inefficiencies; high hardness of water washed clothes will be hardened, the color and luster of the gradually darken and yellow.
And the water softener treated water heating will not be scaling, conducive to the safe and effective use of the heater; washing clothes, towels, colorful, soft; after bathing skin smooth and moisturizing. Therefore, water softener is a necessary choice for high quality of life.
The softener consists of three main parts: resin tank (main tank and pay tank), hydraulic control valve and salt tank. Unlike all other automatic softeners, the water softener does not require electricity to operate, and can operate automatically only by the pressure of raw water. The basic principle is: the two turbines inside the hydraulic control valve drive two sets of gears under the impetus of water flow, which cleverly drive the opening and closing of valves of different channels according to the change of accumulated flow, and automatically complete the cycle process of running, regeneration, clearing, discharging, and replenishment of the salt tank of the water softener, as well as switching between the two tanks automatically, with one standby for the other, to ensure the uninterrupted supply of soft water.
