What is the function of alum in water
Alum can ionize al3+ metal ions in water, while al3+ is easily hydrolyzed to form aluminum hydroxide colloid. Aluminum hydroxide colloid has strong adsorption capacity, which can adsorb suspended impurities in water and form precipitation to clarify water. Aluminum contained in alum is harmful to human body. Drinking alum purified water for a long timeHow much alum does a standard swimming pool need
About 1000 cubic meters of alum
Why is the water blue in the swimming pool? What substances are added and what is the function
In addition to copper sulfate, sodium hypochlorite and alum are commonly added to the swimming pool. Copper sulfate is mainly used to kill algae in the swimming pool. Sodium hypochlorite is mainly used for disinfection. Alum mainly plays the role of precipitation. There are two ways to keep the water clean. The first is to use the drug pump to automatically add drugsWhich of the following fungicides is added to the swimming pool to make the water blue A. alum B. table salt C. copper sulfate D
B. When salt dissolves in water, it forms a colorless solution, so the bactericide added to the swimming pool is not alum; Therefore, B is incorrect; C. Copper sulfate dissolves in water to form a blue solution, so the bactericide added to the swimming pool may be copper sulfate; So C is correct; D. Hydrated lime is caAlum in swimming pool  strong adsorption capacity of aluminum hydroxide colloidlcium hydroxideWhat are the common chemicals for swimming pool water treatment
Sodium hypochlorite - sodium hypochlorite is a kind of dangerous strong oxidant, which is usually light yellow green or colorless liquid, with strong sterilization effect. Commonly used flocculants mainly include aluminum chloride, alum, aluminum sulfate and other polyaluminum chloride - yellow, grayish yellow or red yellowWhat is the function of putting alum in the pool? How much alum does a cubic meter need
It Alum in swimming pool  strong adsorption capacity of aluminum hydroxide colloidshould be alum. It can sterilize and dust. Use a large bucket of water, add 2 kg of alum to dissolve, and pour into the pool. The next day, the bottom of the pool was vacuumedWhy is the pool water muddy and white
There are many reasons for the turbidity and whiteness of the swimming pool water ~ the design quantity of the circulating filtration system is insufficient: this may be caused by the difference between the use purpose at the beginning of the design and the actual operation goal. Water quality balance: the water quality of the swimming pool tends to scale in the water quality balance, that is to sayHow to use alum in swimming pool
To keep the water quality of the swimming pool clean, generally: kill algae with copper sulfate, sterilize with bleaching powder, precipitate wiAlum in swimming pool  strong adsorption capacity of aluminum hydroxide colloidth alum, and then dust. Use of alum: now put alum into large buckets to dissolve, put oneortwo kilograms in one bucket, and then sprinkle alum water evenly into the swimming pool before the end of work at night, and wait for dust collection the next morningWhat if we put too much alum in the swimming pool
Dilute with water. Alum is a white solid. Alum is actually an aluminum coagulant, and its pH value is acidic. The principle of alum in water is the same as that of aluminum chloride, which is used to precipitate and clarify the water quality. Its dosage is about 20-25kg 1000m3 waterHow long can alum play the role of water purification in the swimming pool
Alum, Kal (SO4) 2 and 12H2O, is a complex salt. It is completely ionized to produce al3+, and al3+ hydrolyzes to produce Al (OH) 3. It is a colloid. The colloidal particles are positively charged, while the sediment and other particles are negatively charged. The two occur aggregation and sedimentation, that is, when the impurities settle, the water becomes clear
