Polyelectrolyte Chemicals

Synthetic Polyelectrolytes are extensively used in treatment of water and waste water. Their use increase the efficiency of the treatment processes, reduce cost of chemicals required produce smaller quantity of compact sludge which can be drained / disposed easily. Synthetic Polyelectrolytes help in water clarification remove suspended and colloidal particles which may consists of clay and silt, color bodies, precipitated iron or manganese oxide, and bacteria and algae. However most water require charge neutralization, if negative charge be neutralized the term coagulant applies to cationic chemicals. Flocculation by polymer coagulants is brought via their molecular weight (M.W.) which is very high compared to inorganic chemicals.

Anaerobic bacteria agent

Character of commodityPowder

Main ingredientsThe bacterium agent consists of the bacilli and cocci which can form spores (endospores).

Living bacteria content≥20 billion/g

Range of applicationSuitable for the hypoxia system of municipal waste water treatment plants, all kinds of industry chemical waste water, printing and dyeing waste water ,garbage leachate, food industry waste water and other industry waste water treatment.

 

Main functions】:

n Aerobic bacteria agent has good degradation function on organic matter in water. Because of spore bacteria has extremely strong resistance to the harmful factors of the outside world. It can make the sewage treatment system has higher ability of resist impact load, and has strong handling capacity , the system can run properly when the sewage concentration changing dramatically ,ensure effluent discharge stability.

n Aerobic bacteria agent can remove BOD, COD and TTS effectively. Improve the solid settling capacity in sedimentation basin significantly, increase the number and diversity of protozoa.

n Start and Recovery System Quickly, improve processing capacity and impact resistant ability of the system ,reduce the amount of residual sludge generated effectively ,reduce the use of chemicals such as flocculant ,save electricity.

 

Usage and dosage】:

1.According to water quality index into the biochemical system of industrial wastewater:the first dosage is about 80-150 grams/cubic (according to volume calculation of the biochemical pond).

2.If it has too big impact on biochemical system caused by fluctuations feed water, the improved dosage is 30-50 grams/cubic (according to volume calculation of the biochemical pond).

3.The dosage of municipal wastewater is 50-80 grams/cubic (according to volume calculation of the biochemical pond).

 

Parameters】:

The test shows that the following physical and chemical parameters for bacterial growth is most effective:

n PH: In the range of 5.5 and 9.5, most rapidly growth is between 6.6~7.8, the practice proved the best processing efficiency in PH 7.5.

n Temperature: it will take effect between 8℃~60℃. Bacteria will die if the temperature is higher than 60℃. If it is lower than 8℃, it will not die ,but the growth of bacteria will be restricted a lot. The most suitable temperature is between 26~32℃.

n Dissolved oxygen:The dissolved oxygen at least 2 mg/l in the aeration tank of waste water treatment ; the metabolism and degradation speed of high resilience bacteria to target substance will accelerate 5~7 times with enough oxygen.

n Trace Elements : Proprietary bacterium group will need a lot of elements in its growth , such as potassium, iron, sulfur, magnesium, etc. Normally , it contains enough elements in soil and water.

n Salinity: It is applicable in salt water and fresh water ,the maximum tolerance of salinity is 6%.

n Poison resistance : Can more effectively resist chemical toxic substances, including chloride, cyanide and heavy metals ,etc.

 

Notice: when the contaminated area containing fungicides, should research the effect of them for microorganisms in advance.

aluminum hydroxide IP 99.8%

It is produced by precipitation method with the sodium aluminate solution from sintering process as the seeds. Slow decomposition, complete crystallization, low impurity, high intensity and good penetration.

It has the texture properties of jade, which can be used as superior filler in the solid surface, crafts and other composites. 

High whiteness (has the reputation for Chinese Whiteness), low oil absorption, steady in room temperature and dehydrated to alumina while heating, to make the products have the function of flame retardant. It’s good flame retardant filler because that no toxic and corrosive gases were generated in thermal decomposition. It’s widely used in the solid surface, mould plastics, epoxy potting compound and other composite materials.
