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

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 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?: The main content is not the same

Q: Last called me to buy salt, but can buy a bag of alkaline powder to go home. Want to know what can use alkali powder?: Hair thicken

Q: What is the name of the alkali?: Its scientific name is [sodium carbonate].

Q: What is the role of alkali in the surface: Nutritional analysis: 1. In the process of hair will have a microbial acid, dough after the initiation of acid, must be added to the alkali (carbonate) to acid off in order to produce a delicious pasta; And dark green vegetables due to the excessive spraying of pesticides and organic acids or sulfide, which can keep the original color of vegetables and pesticides to remove the pollution of vegetables; 3. Alkali has a strong role in degreasing, can Remove the oil on the dry goods on the raw material of excess oil; 4. Alcohol can release corn is not easy to release nicotinic acid, so that long-term consumption of corn will not be due to the lack of nicotine in corn and suffering from niacin; The disadvantage is that the food in the vitamin b1, b2 and vitamin c 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 the big base?: Large alkali is the main component of sodium carbonate.

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

Q: What are the characteristics of the composition of the base?: The anions obtained when ionizing are all OH- are bases; alkali: OH- and metal ions (or NH4).

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
