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
	High purity			Refined
Appearance	white or grey white powder
Ca(OH)2(%) ≥	95%	92%	90%	88%	80%	70-75%
Mesh	400	200	200	200	200	150
Hydrochloric acid insoluble, %	0-0.7			0-1.0

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 white alkali?: White alkali is dough (soda, soda ash), scientific name sodium carbonate, chemical formula Na2CO3.

Q: Why does not the base noodles rub?: May add too much water. Noodle black is caused by alkali, you can use the source of gluten instead of edible alkali.

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 the difference between baking base and common base?: What the main content of ah, is not a thing. Baking alkali refers to caustic soda, caustic, caustic soda, and molecular sodium hydroxide, while the commonly used edible base refers to sodium carbonate.

Q: What to do with the wall: Wall latex paint suggest you re-done. Especially to make the primer

Q: A bit tall please help me one!: China Battery Industry Association executive vice president and secretary general Wang Jingzhong pointed out: "green alkaline alkaline manganese battery products," the introduction of China's alkaline manganese batteries marked the main environmental indicators have reached the world advanced level. This time the introduction of alkaline manganese battery brand, the battery mercury content of 0.0001% below, and not contaminated soil mercury content close. Waste batteries have little impact on the environment. According to the State Environmental Protection Administration on October 9, 2003 announced the "waste battery pollution control technology policy" provides that the waste mercury-free alkaline manganese batteries can be mixed with domestic waste collection and landfill.

Q: Do you eat too much alkali to harm your body?: Excessive intake of alkali hazards: The disadvantage of edible alkali is the food in the vitamin B1, B2 and vitamin C has a strong destructive effect, and will affect the body of certain minerals absorption and utilization, so do not overuse.

Q: The commonality of the base: alkaline solution can react with non-metallic oxides, generate salt and water

Q: What is the harm to the human body?: The disadvantage of soda ash is the vitamin B1, B2 and vitamin C in food have a strong destructive effect, and will affect the body of certain minerals absorption and utilization, and therefore can not be abused.

Q: What is alkali?: What is the alkali is the ionic compound, the ionization of the anion is hydroxide (OH-), in fact, the oxygen ion acid root (which can compare sulfur and sulfur), and the anion contains only hydroxide. (Such as LiOH, NaOH, NH3 · H2O) soluble in water, alkaline earth metal ions formed in the periodic table from top to bottom gradually soluble [Be (OH) 2, the alkali metal ions or alkali ions, Mg (OH) 2 is insoluble, Ca (OH) 2, Sr (OH) 2 is slightly soluble, and Ba (OH) 2, Ra (OH) 2 is easily soluble, and other bases are in addition to TlOH and Tl (OH) Is difficult to dissolve alkali and acid metathesis reaction is also known as neutralization reaction, that is, H + + OH- == H2O
