What are the four ways to purify water?

There are three categories of water purification products: filtration, softening, and purification.

Water purification products are mainly divided into three categories: filtration, softening and purification.

Use sand filter, activated carbon.

Water purifiers with technologies such as ultrafiltration can purify water sources to a certain extent. It can remove sediment and rust, but cannot completely remove scale, bacteria and viruses, and belongs to primary filtration. Water purifiers using KDF filter media can partially remove bacteria and viruses, and partially remove heavy metals, but cannot remove scale.

The water softener basically uses ionic resin exchange technology and uses sodium-type cations.

Replace calcium and magnesium ions (water alkali) in the water and completely remove scale. The water purifier adopts reverse osmosis membrane.

Filtration technology, the core is microporous filtration, only water molecules.

and minerals and trace elements smaller than water molecules.

It can pass through the membrane and remain for drinking; Bacteria, viruses, scale, and pollutants cannot pass through the membrane and are discharged as concentrated water; So as to meet the standard of high-quality drinking water.

The method of water purification consists of adding a suspension-suspension of an adsorbent made by electro-erosion and dispersion of ferrous metals in water with a magnet content of not less than 3% (by weight), stirring and sequential solid-phase separation. The amount of suspension added to the water, according to the dry matter, needs 3-120 grams for each gram of purified impurities. A method for purifying water, which comprises adding an iron-based adsorbent to water, stirring and subsequent solid-phase separation, which is characterized by using a suspension made of ferrous metals electro-etched and dispersed in water as an adsorbent, in which the magnetite content in the solid phase is not less than 3% (by weight).

The gradient microporous ceramics with a filtration accuracy of microns and the ingenious design of the water filter channel solve the contradiction between the filtration accuracy and the insufficient water flow power, so that the bacterial removal rate of this product is close to 100%, the turbidity removal ability is almost perfect, and the macromolecular organic matter in the water can be effectively removed;

2.The softening function of the water purifier can reduce the hardness components in the water by more than 70%, and the removal of heavy metals is particularly effective, especially suitable for users in hard water areas (the water quality in most areas north of the Yangtze River in China is hard);

The use of high-quality silver-loaded activated carbon can effectively remove small molecule organic matter, residual chlorine, tap water disinfection by-products (such as halogenated hydrocarbons, etc.), color, taste, heavy metals and other toxic and harmful substances in the water, improve the taste of water, at the same time, the continuous slow release of silver ions has long-term sterilization and antibacterial functions, effectively preventing bacteria from multiplying in the filter element;

4.The organic combination of siphon and downflow filtration methods, as well as the ingenious exhaust structure, can exhaust the air in the filter element, greatly improve the utilization rate of activated carbon, and fully purify every drop of water;

5.It can purify ordinary municipal tap water into high-quality drinking water.

<> methods of water purification include distillation, semi-permeable membrane method, precipitation method, and adsorption method.

1. Distillation method: It is a common method for separating and purifying liquid mixtures, and can also determine the boiling point of liquid compounds.

2. Semi-permeable membrane method: use a semi-permeable membrane with a large pore size to make the solvent and electrolyte in the solution pass through the semi-permeable membrane, while colloids, particles and substances with large molecular weight are intercepted.

3. Precipitation method: In water treatment, it is a process that uses the sedimentation performance of suspended particles in water to produce sinking under the action of gravity to achieve solid-liquid separation.

4. Adsorption method: use porous solid adsorbent to adsorb one or several components in the water sample on the surface, and then use suitable solvent, heating or blowing to decompose and absorb the first group to achieve the purpose of separation and enrichment.

Water purification methods are:

1. Static precipitation method: the colloidal matter generated after alum is dissolved in water adsorbs impurities and precipitates impurities.

2. Adsorption and precipitation method: filter the liquid with a solid with adsorption effect to filter out the insoluble substances in the liquid.

3. Filtration: Separate the insoluble solid matter from the water.

4. Distillation: According to the different boiling points of each substance, the liquid substances dissolved in each other are separated.

About Water Purification:

Water is the source of life, both ordinary and precious, there is very little water on the earth, but rational use can meet human needs. Insufficient and unevenly distributed freshwater resources, as well as increased human activities, threaten to make "water a profound social crisis in the near future", so water purification has become an essential project.

Water purification refers to the process of purifying and treating water that contains many soluble and insoluble impurities in nature and is often in a turbid state through various ways. The commonly used methods of water purification are: adsorption, precipitation, filtration, distillation, etc., respectively, the role is to stand

Settles insoluble large particulate matter.

Adsorption is the addition of alum, the formed colloidal matter adsorbs and settles impurities; Activated carbon, which uses its adsorption to remove suspended impurities and odors. Water purification effect of activated carbon: it has a porous structure and has a strong adsorption capacity for gases, vapors or colloidal solids.

It can adsorb pigments and make liquids colorless, and can also deodorize odors.

Water purification substances mainly include inorganic aluminum sulfate, ferrous sulfate, aluminum chloride, polyaluminum chloride, polyferric sulfate, etc., organic anionic, nonionic, cationic polyacrylamide and sodium polyacrylate, and acrylamide aqueous solution. In addition, there are bleaching powder, activated carbon, alum, various ion exchange resins, etc.

The process of removing rust, sediment, residual chlorine, organic matter, harmful heavy metal ions, bacteria, viruses, etc. from water in a physical or chemical way according to different final water needs. Obviously, if the whole process of water purification is physically filtered, it will not produce or add any new substances to the water, let alone change the properties of the water, so it is the safest way and is widely used in Western countries. Water is purified and substances that are harmful to human health are removed, which we call "clean water".

The Concept of Binary Linear Equations The form of a binary linear equation.

Definition: An equation that contains two unknowns, and the number of terms containing unknowns is 1, is called a binary linear equation.

The second ......A bit of a problem, if the landlord is really asking "binary equations" instead of "binary equations", then its general form should be ax+by=c (a, b is constant) that is, indefinite equations.

In the case of a system of binary linear equations, the general form should be a1x+b1y=c1a2x+b2y=c2 (a1, a2, b1, b2, c1, c2 are constants).

Water purification method adsorption, static precipitation, filtration, distillation four kinds, water purification refers to the purification process of removing pollutants from raw water, its purpose is to achieve the effect of water purification with a specific procedure, and use water for different purposes, water in nature because it contains many substances and bacteria, so it is a mixture that is not suitable for direct drinking, according to the different water quality, it is necessary to purify the water.

1. Adsorption method: Filtering the liquid with solid with adsorption can filter out the insoluble substances in the liquid, and can also adsorb some dissolved impurities and remove odors. Such as:

Some water purifiers use activated carbon to adsorb and filter impurities in water. Although the purified water has been clarified, the resulting water is still not pure world stove water.

2. Static precipitation method: the adsorption of impurities by the colloidal matter generated after alum dissolved in water is used to precipitate impurities to achieve the purpose of water purification.

3. Filtration: a method of separating the solid substances that are insoluble in the liquid from the liquid resistance.

4. Distillation: According to the principle of different boiling points of each substance, the liquid substances dissolved in each other are separated. The degree of purification is relatively high. The process of making distilled water is a physical change.
