High purity hydrated lime for water treatment

Management Certification: SGS; ISO 9001:2008;MSD

High purity hydrated lime for water treatment

1. Features

1). Lower cost for water treatment

2). Widely range of application

3). Aid to coagulate well

2. Application

1). Mainly adjust acid waste water PH value, widely used for electroplate,

Chemical industry, circuit board, pickling, printing & dyeing and paper making

industries waste water treatment.

2). Used to remove phosphate,most of the heavy metal and ammonia nitrogen etc.

3).Used to adjust up water PH value of water supply plant

3. Quality Specification

Executive Standard QB1001-2011

Item	Index

4. How to Use

Wet dosing: Firstly, make it up to 5%-10% solution and continuously mechanical stir. Add to waste water after it completely mixed into suspension & turbid liquid until the PH value come to target value

Dry dosing: add it directly to the reaction pool, control of its dosing through the ph value. This method is suitable for dealing with strong acidic sewage; adjust the ph value to rough though its strong alkalinity.

5. Packing, Storage and Transportation

Packed with 25 kgs woven bag or paper bag.

Stored in dry ,cool and ventilate place, it will keep good for 6 months.

Q: What is alkali sand: Potassium carbonate, white crystalline powder. Density of 2.428g / cm3. The melting point of 891 ° C, the decomposition of boiling point, the relative molecular weight of 138.21. Soluble in water, aqueous solution is alkaline, insoluble in ethanol, acetone and ether. Hygroscopicity, exposure to air can absorb carbon dioxide and moisture, into potassium bicarbonate, should be sealed packaging. Hydrates have a water, dihydrate, sour things. Potassium carbonate aqueous solution is alkaline. Insoluble in ethanol and ether.

Q: What is called alkali recovery: Extraction equipment extraction status is good or bad, largely depends on the extraction of equipment. Different pulp, there are different equipment selection. At present the factory application is the most four series of drum-type vacuum washer. Its technology is mature, easy to operate, from the pulp into the pulp, the basic completion of the separation of pulp and black liquor, the extraction rate is also high. Pulp washing degree and the production of black liquor indicators are basically able to meet the choice of more manufacturers. The disadvantage is the big investment, power consumption.

Q: What is the difference between baking base and common base?: The aqueous solution of the two is worse. Do German or use the baking base, I have tried, not only different colors, taste and taste are also significantly different.

Q: What is the important character of Chinese made alkali?: Hou Diping famous chemist, "Hausdorck Alchemy" founder. He has worked for China's chemical industry and has been known for his life in the world. Sodium carbonate is used extensively. Although people have been from the saline soil and salt lake in the sodium carbonate, but still can not meet the needs of industrial production.

Q: How to go to the base of the teapot: With a rinse rinse just fine

Q: Is the base and baking soda the same substance?: Alkali and baking soda is not the same definition, white horse is a horse, but the horse is not necessarily white horse, baking soda is alkali, alkali including baking soda

Q: Alkali soda water: In 1772, Joseph Plistree published a book, "Combination of Water and Gas," describing the drop of sulfuric acid on chalk, releasing carbon dioxide and encouraging people to collect gas with a bowl full of water. In 1771, the Swedish chemist Luben Bergman independently invented a manufacturing process similar to that of Joseph Plistry's discovery of carbonated water. But less successful, he managed to produce natural bubbling spring water, then think that bubbling spring is good for health. Now, carbonated water is made by pressurized carbon dioxide through water. The pressure of the pressure is stronger than the standard atmospheric pressure, so that it increases the solubility, so that carbon dioxide into the. When the bottle is opened, the pressure is released, the gas forms a bubble out, thus forming a unique bubble. The best known for carbonated water is the advantage of removing stains, such as coffee stains in coffee cups, or silver stains. It is said that the wine stains can be mixed with salt, and then add a lot of carbonic acid to remove. Carbonated water is available at the grocery store and is also very simple. To the supermarket condiment counter bought to eat soda powder. Then prepare a bottle of mineral water. Will be a drink of water cups, put a spoonful of soda powder, how much soda powder can be based on personal taste to set. If put more, too salty, some people can not stand, put less. And then filled with mineral water, pay attention to the water must be cool. Now the living standard is good, every day big fish and meat eat, the body eat into acidic, drink soda can be neutralized in the body acid and alkali balance, good for health. Drink once or twice a week, stick to it, the body will feel particularly cool.

Q: That day, I put the alum in the water, and then I smell the gas, I would like to know the alkali is not harmful to people, right?: In the process of hair will have a microbial acid, dough after the initiation of acid, must be added alkali, in order to produce a delicious pasta;

Q: What is the big base?: Large alkali is the main component of sodium carbonate.

Q: What is the alkaline powder? Baking soda? Sodium carbonate or something else?: Baking soda is very easy to absorb the air of the air, so when not in use when the best way to retract, such as sealed cans or folder chain or milk powder cans. Use, you can use a commercially available pepper to retract, but not Add the lid, pepper cans of the hole is very easy to sprinkle the small soda.There is no pepper cans, you can also have a hole in the cloth, such as not the yarn quality curtains, mosquito nets, etc., tied tied to the general bottle, It is easy to pour out to use.If you just want a simple moisture and deodorant, you can put the small soda in the old cotton socks, and then sealed with a rope, and then any use can be
