Fluorine Removal Equipment

　　Fluorine removal equipment

　　There are so much underwater containing fluorine, and the density of fluorine exceed the national standards, if not treated, they cannot become the drinking water, drinking the water with high-density fluorine, the people will have the fluoroses, which can affect human’s health, at best, which can cause black teeth, mottled enamel, enamel drop, early dedentition, at worst, which can cause osteosclerosis even skeletaldeformity. Therefore, in order to guarantee the physical and psychological health of people and protect the environment, our company has developed the fluorine removal device carefully, which can make the water after treatment conform to the national drinking water standards, that is to say, the fluorine content is less than 1mg/L, the industrial sewage water after treatment also can conform to the emission standards of industrial three-waste.

　　I. Working principle

　　When raw water enters into the internal core part of fluorine removal machine, the water will contact with the key media of fluorine removal machine, with the physical and chemical reaction, the fluorine of the water will be removed. After a period of operation (about three months), when the fluorine removal material loses effectiveness, this machine needs the regeneration, after that, the machine can operate again. And the regenerant is the aluminum potassium sulfate (the alums).

　　The fluorine removal agent is used to purify the water quality, which takes use of strong physical adsorption to realize the seepage, to have the cation exchange, the sodium and calcium ions in the fluorine removal agents can exchange with the potassium and magnesium ions in the solution, in the industry, which can be used to soften the hard water. Because of the diversity of structure, there are many cavities with different sizes in the crystal lattices, which can adsorb or filtrate the molecule with different sizes of other substances.

　　The unit of mineral structure is consisted of oxygen-silicon tetrahedron and oxygen-aluminum tetrahedron, these tetrahedrons will arrange to crystal skeleton with different shapes based on the certain laws, so the mineral skeleton structure is open, sponge, which has many uniform cavities and channels, metal cation and hydrone. These cation and hydrone have weak connections with anion skeleton. Such special structure decides the the performances of adsorption, selective ions exchange and catalysis.

　　II. Operation parameters and application conditions

　　1. Flow rate of run: 2m/h

　　12. Fluorine content of output water: <1mg/l

　　III. Suitable scopes

　　This kind of device is suitable for the fluorine removal needs of well water with the medium and small-scale cities and towns, factories, which can also meet the the fluorine removal requirements of industrial sewage treatment.

　　IV. Device feature

　　1. Fluorine removal agent is new, whose basic material is natural mineral elements, after chemical manufacture, then becomes the activated filter material. Its fluorine removal efficiency is good, and the performances are stable.

　　2. The treatment technology is the filtration, the equipment structure is simple, which has the small area and convenient operation.

　　3. The equipment can remove the fluorine, heavy metal ions, chroma, organic matters and so on.

　　4. The fluorine removal agent is durable, which has the long operation cycle, whose price is more competitive.

　　5. The fluorine removal device adopts A3 steel to manufacture carefully, the internal and external wall has the special corrosion resistance treatment, which is more durable.
