How The Water Purifier Works
Dec 17, 2018

First, the water softening

1. Ion exchange softening method: ion exchange is performed by using cations such as H+ and Na+ in the active gene of the ion exchanger and Ca2+ and Mg2+ in the water to remove Ca2+ and Mg2+ for softening.

2. Working process: adsorption, saturation and reduction.

3, softened water refers to the water hardness mainly refers to calcium and magnesium ions in water, to remove or reduce a certain degree of water, mainly used in boiler water.

4, the role of activated carbon in water treatment: the use of carbon-based substances as raw materials, high temperature carbonization and activation of the thinning adsorbent.

5. Widely used in domestic water and food industry, chemical industry, electric power and other industries. Purification, dechlorination, degreasing and removal of organic matter from industrial water.

Second, the basic principle of electrodialysis

1. Dialysis refers to the phenomenon that the solute in the solution passes through the semipermeable membrane. The driving force of natural dialysis is the difference in the concentration of the solute on both sides of the semipermeable membrane. Under the action of the direct current electric field, the phenomenon that ions pass through the selective ion exchange membrane is called Electrodialysis.

2. The ion exchange membrane is a membrane made of a polymer material and selectively permeable to ions, and is mainly composed of a cation exchange and an anion exchange membrane.

3. The basic working unit of the electrodialysis process is a membrane pair: a membrane pair constitutes a desalting chamber and a concentration chamber. It consists of a positive membrane, a freshwater separator, an anion membrane and a concentrated water separator. A practical electrodialysis consists of hundreds of membrane pairs.

4, the main application areas are brackish water desalination, seawater desalination, pure water preparation and beverage, pharmaceutical, mineral water, dairy products and other industries.

Third, the principle of ultrafiltration

1. When water flows through the surface of the membrane under a certain pressure, only water, inorganic salts and small molecular substances are allowed to pass through the membrane to prevent the passage of macromolecular substances such as suspended solids, colloids, proteins and microorganisms in the water to achieve the purification of the solution. , the purpose of separation and concentration.

2. Ultrafiltration is a membrane separation technique that purifies, separates or concentrates a solution.

3. Application: Remove particles, colloids, bacteria, heat sources and various organic substances in water.

4. It is usually understood that the screening process is related to the size of the membrane pores, and the pressure difference between the membranes is used as the driving force, and the ultrafiltration membrane is used as the filtration medium.

Fourth, the principle of reverse osmosis

1. The main application fields are: desalination of seawater and brackish water, preparation of pure water and ultrapure water, treatment of industrial water, purification of drinking water, etc.

2. Add a higher pressure than the natural osmotic pressure on the side of the dope, reverse the natural infiltration direction, and press the solvent in the concentrated solution to the dilute solution on the other side of the semipermeable membrane, which is contrary to the normal infiltration process in nature.
