Is tap water cloudy salt or alum?

The chemical name of alum is potassium aluminum sulfate.

Alum is hydrolyzed with aluminum ions in water to form an aluminum hydroxide gel, which has a huge specific surface area.

And the surface has a charge, has a very strong adsorption capacity, can adsorb the suspended solids and some heavy metal ions in the water, and precipitate down, so that the water is clear. Therefore, alum, or other aluminum salts are commonly used water purification agents.

Answer, the turbid tap water is not salt, but should be put alum, because alum has the effect of sterilization and turbidity.

If the tap water is turbid, you can put a little alum to let the turbidity settle, so that the water will become clear, and salt does not have this effect.

When I was younger, it was all muddy water, and the water was muddy like this:

1. Put it in a large vat to settle naturally, use the upper layer of light water, and be sure to boil before drinking.

2. If the water is still turbid after 2 days, then put a small piece of alum (potassium aluminum sulfate) into it. Potassium aluminum sulfate will hydrolyze the aluminum hydroxide colloid, which combines with the suspension in the water to form larger particles that are easy to precipitate. When alum is added, the water produces white flocculents.

After adding alum, it should also be allowed to settle down.

3. There are two water tanks in high and low places, put muddy water in the high, buy a white cloth, soak it, sink one end into the muddy water tank at the high place, and put the other end in the lower water tank, the low water tank, and the water tank can be collected in one night. Do it again if necessary.

Salt, no water purification effect, do not put.

Alum is a statement in books, and the folk are called alum

Tap water is cloudy and needs to be put alum.

In the past, when the water was turbid, people generally put in a small amount of alum, so that the impurities in the water would condense and precipitate, and the upper water would become clear and easy to use.

Nowadays, society stresses health and science, and this method is no longer adopted.

When the tap water is turbid, alum can release an electric charge to precipitate colloids and make the water clear.

Putting alum, salt does not have the function of purifying water quality.

Alum is also known as alum, potassium alum, potassium alum, potassium alum, potassium alum, potassium aluminum sulfate dodecahydrate. It is a double salt of potassium sulfate and aluminum sulfate containing crystalline water. Chemical formula KAL(SO4)2·12H2O, formula, colorless cube, monoclinic or hexagonal crystal, with glass luster, density, melting point.

9 molecules of crystal water are lost, and 12 molecules of crystal water are lost at 200 hours, which are soluble in water and insoluble in ethanol. Alum has a sour taste, is cold, and poisonous. Therefore, it has antibacterial effect, astringent effect, etc., and can be used as traditional Chinese medicine.

Alum can also be used to prepare aluminum salts, baking powders, paints, tanning materials, clarifying agents, mordants, papermaking, waterproofing agents, etc. Alum water purification is a method often used by the folk in the past, and its principle is that alum can ionize two metal ions in water:

Kal(SO4)2 = K+ +Al3+ +2SO42- while Al3+ is easily hydrolyzed to form colloidal aluminum hydroxide Al(OH)3:

Al3+ +3H2O = Al(OH)3 (colloid) + 3H+ aluminum hydroxide colloids have a strong adsorption capacity, which can adsorb impurities suspended in water and form a precipitate to make the water clear. Therefore, alum is a better water purification agent.

In the past, alum was used to precipitate turbid water sources, but now turbid water sources include sand filtration, carbon filtration, and hollow filament membrane filtration, which can filter the turbid water source clearly and transparently, and salt is impossible to become a filter material....

Some places do not use, alum belongs to the inorganic flocculant in the quite good variety, mainly cheap, the role is the aluminum salt inside, now the aluminum salt pattern is more, the highest efficiency is currently recognized as 6 aluminum, other organic polymer flocculants are also a lot, like polyacrylamide is more commonly used, but the monomer is toxic, inorganic ferric chloride and the like, there are a variety of flocculants in combination, if you are interested, you can find ** see.

Can you use alum when the tap water is turbid, yes, but you can't take the tap water sterilized by alum for a long timeAt present, most of the tap water disinfection is chlorinated.

Alum can make the turbid tap water clear and clear!

The more primitive method is to rely on precipitation or alum, and now the method of filtration is generally used, and there are many materials for filtration, such as stones, sand, carbon, filter elements, various purifiers, and filter membranes, ......And so on.

Yes, alum is sodium aluminum sulfate, aluminum ions are hydrolyzed in water to form aluminum hydroxide colloid, colloids have adsorption properties, can adsorb particles suspended in water, aluminum salts are generally used as flocculants.

It is recommended that you leave the tap water for 30 minutes, is it still cloudy? If so, there should be a rupture in your water pipes, and the tap water is contaminated! If the water becomes clear after 30 minutes, it means that there is a little in the water.

Summary Hello: Generally one liter of water is added with 750mg of alum! One ton of water is 1,000 liters, that is, kilograms of alum! That's how much you dose!

The tap water pool is turbid, and how many grams of edible alum can be put in 1 ton of tap water to play a role in water purification.

Hello: Generally one liter of water is added with 750mg of alum! One ton of water is 1,000 liters, that is, kilograms of alum! That's how much you dose!

That is, a ton of water needs a pound of alum, specifically like this, I hope it can help you!

Thanks for the advice. You're welcome, drinking too much alum water is harmful to the body, it is not recommended to do this often, just let it settle on its own!

If the tap water is cloudy, alum is generally used. But in fact, now industrial water purification or water purification of water plants and effluent purification of sewage plants generally use polyaluminum chloride instead of alum. If you use alum to purify water, be careful not to drink it directly to avoid causing physical discomfort.

What is alum.

Potassium aluminum sulfate dodecahydrate, also known as alum, is an inorganic substance with the chemical formula kal(SO4)2·12H2O, which is a double salt of potassium sulfate and aluminum sulfate containing crystalline water.

Alum, soluble in water, can be used as traditional Chinese medicine, and can also be used to prepare aluminum salts, baking powder, paints, tanning materials, clarifiers, mordants, papermaking, waterproofing agents, etc., and is often used for water purification in life.

Because long-term consumption of aluminum-containing food additives is very harmful to the human body, especially on children's growth and development and intelligence, the state has banned the use of alum in food additives.

Tap water is cloudy and alum. Alum usually refers to potassium aluminum sulfate dodecahydrate, which is an inorganic broad spring substance, containing a double salt of potassium sulfate of crystalline water and aluminum sulfate. Soluble in water, insoluble in ethanol.

Alum has a sour and astringent taste. Alum has antibacterial effect, astringent effect, etc. Alum can be used to prepare aluminum salts, baking powder, paints, tanning materials, clarifiers, mordants, papermaking, waterproofing agents, etc., and is often used for water purification in life.

The tap water just came out of the turbid alum.

As soon as alum touches water, it undergoes a chemical change, and in this chemical change, potassium sulfate is only a supporting role, and the protagonist is aluminum sulfate, which produces a white flocculent precipitate - aluminum hydroxide after the chemical change between aluminum sulfate and water. This aluminum hydroxide is also a colloidal particle. Also carries an electric charge.

The difference is that the aluminum hydroxide pellets are positively charged.

As soon as it touches the negatively charged sediment particles, they neutralize each other. The limb grains, which have lost their electric charge, soon coalesce, and the particles grow larger and larger, and finally sink to the bottom. In this way, the water becomes clear and clean.

Alum uses. It is mainly used as a coagulant for warm turbid water and plays a role in purifying water quality. It is used as a sizing agent in the paper industry, and is used in combination with rosin emulsion for paper sizing to improve the water resistance strength of paper.

It is used as a preservative, astringent, and hemostatic agent in the pharmaceutical industry. It is prepared into a certain concentration of aqueous solution, which can be used to prevent rice dermatitis; It is also a pickled preparation of Chinese medicinal materials Banxia and Nanxing. It is used as a colorant for yellow medical glass in the light industry.

It is used as an aluminium tanning agent in the tanning industry.

It is used as a sizing agent in the paper industry, and is used for paper sizing in combination with rosin emulsion to improve the water resistance strength of paper. It is used as mordant, retardant and anti-dyeing agent in the printing and dyeing industry. It is also used as a raw material for the production of other aluminum salts, and in the manufacture of matches, paints, etc.

It is used as a chemical reagent in analytical chemistry for the determination of iron, manganese, antimony, and aluminum, and as a hardener for bacterial staining.

Alum is a compound salt of potassium sulfate and aluminum sulfate containing crystalline water, soluble in water, has antibacterial effect, can be used to prepare aluminum salt, baking powder, paint, tanning, clarifier, mordant, papermaking, waterproofing agent, etc., and can also be used to purify tap water. However, it is not good for people's health to take tap water sterilized with alum for a long time.

The solution to the turbidity and yellowing of tap water.

1. Open the faucet and release water for a period of time, and drain the old water, sediment and rust in the pipeline, and the water quality can return to normal in a short time.

2. The property of the community should monitor the water quality of the internal pipe network of the community by opening the fire hydrant regularly, and when yellow water is found, it will be discharged in time, so that the new water of the municipal water supply network can enter the community, and the water quality can be restored to normal after the normal circulation of tap water.

3. Regularly clean and disinfect the roof water tank or secondary water supply equipment, and strengthen the management of secondary water supply facilities.

4. Strengthen the management of pipeline construction and pipe burst repair, after the pipeline construction is completed and the emergency repair is completed, the pipe network should be flushed, and the water supply can only be supplied after the water quality test is qualified.
