Anionic polyacrylamide is a kind of water-soluble linear polymer, which is formed by adding the alkali into acrylamide, then through hydrolysis and synthesis, soluble in water, hardly soluble in general organic solvents, such as benzene, ether, acetone, lipids and acetone etc. Has the property of flocculation, thickening, shearing, resistance reducing and dispersing etc. For the wastewater which the suspended particles with positive charge, pH is neutral or alkaline, due to the molecular chain of anionic polyacrylamide containing a certain amount of polar groups, which can absorb suspended solid particles in water, make bridge between particles to form large flocculate, so has the effect of accelerating the settlement of particles in the suspension, speeding up the clarification of solution and promoting filtering etc. Widely used in the treatment of chemical industrial wastewater and waste liquid, municipal sewage treatment, tap water treatment, high turbidity water purification and clarification, coal washing, ore dressing, metallurgy, iron and steel industry, zinc and aluminum processing and electronic industry and so on.
1. Good water solubility, can also be completely dissolved in cold water, can dissolve in water in any proportion and insoluble in organic solvents.
2. Shows the characteristics of high polymer electrolyte in neutral and alkaline medium, suitable for wastewater treatment with positive charge and rich organic matter.
3. Sensitive to the salts electrolyte, cross-linked into insoluble gel with the high valence metal ions.
4. Applicable to a wide pH range.
5. During the process of adding drug, less dosage, the greatly flocculation effect can be achieved with a small amount of product compared with others.
6. Using the anionic polyacrylamide and inorganic flocculant at the same time (polymeric ferric sulfate, poly aluminum chloride and iron salts etc.), the effect is more obvious.

1. Industrial wastewater treatment
Especially for the effluent which suspended particles coarser, high concentration, particles with positive charge, the water pH is neutral or alkalinity, such as the wastewater of iron and steel plant, electroplating factory, metallurgical and coal washing, the effect is very good.
2. Drinking water treatment
Many headwaters of the waterworks in China from the river water, which the silt and mineral content is high, more turbid, although after sedimentation and filtration, but still can't meet the requirements, need adding flocculant, to make the water clear, many waterworks using inorganic flocculants, but the adding amount is big, causing sludge volume increases and the effect is not good. Using the anionic polyacrylamide as flocculant, dosage is 1/50 of the inorganic flocculants, but the effect is several times to several dozen times better than the inorganic flocculants. Especially the polyacrylamide from our company, residual monomer has reached the food grade( less than 0.05%), close to the foreign advanced level, non-toxic, more suitable for the treatment of drinking water, for the organics polluted river water, in combination with the cationic polyacrylamide, the effect is better.
3. Used in the starch factory and alcohol plant, for the recovery of the loss of starch and distillers' grains.
In the discharge of wastewater of many starch factory contains a high starch content, impact the environment , waste of resources after emission, adding the APAM, make starch precipitation, sediment was pressed into cake by the filter press , which can be used as feed. In the alcohol plant, a large number of vinasse is processed by this way, recovery of vinasse, and achieved great economic benefit.
4. As oil-displacing agent for the oil field tertiary oil recovery.
Can adjust the rheology of injection water, increase the driving liquid viscosity, improve the sweep efficiency of water area , reduce the water phase permeability of the formation, make the water and oil can forward flow at a constant speed. Its role in the oil exploitation is mainly used in oil field tertiary oil recovery, each injection one ton of polymer polyacrylamide can exploit crude oil more 100 to 500 tons than before.
5. Materials for drilling mud
In the oilfield exploration and development, exploration of geology, water conservancy and coal, as additives for drilling mud material, can prolong the service life of drill bit, improving drilling rate and drilling footage, reduce the congestion in the replace drill, prevent collapse effect is obvious. It can also be used as oilfield fracturing fluid and plugging agent in profile control water plugging.
6. Papermaking additives
In the papermaking industry, it can be used as a clarifying agent and filter aid for caustic soda and paper wet strength reinforcing agent.
7. Used as sugar juice clarifying agent in sugar industry.
8. Used as additive and agglomerant in the aquatic feed.
1. When used, prepared 0.1% concentration of aqueous solution, it is appropriate to use neutral excluding salts sundry water.
2. When dissolved, add the anionic polyacrylamide evenly into the stirring water, control well the stirring speed, proper heating (< 60 ºC) can accelerate the dissolution.
3. Through the experiment to choose the best pH and amount of use of the product series. Adjust the treating solution pH, make the series of products give full play to the role.
4.When adding the anionic polyacrylamide solution, should accelerate mixed it with the disposed liquid, reduce the stirring speed when the flocculant appeared, to facilitate the flocculant growth and accelerate it settlement.
5.In general, the solution is used immediately after the preparation, try to avoid using it next day.
1.Solution temperature. Polyacrylamide dissolved requires a certain temperature to accelerate the speed of dissolution. But the temperature is too high, will make the molecular chain of polymer rupture, reduce the use effect, the suitable solution temperature is 50-60 ºC.
2.Stirring condition. Polyacrylamide dissolved should avoid excessive shear force stirring, the excessive stirring will make the molecular chain rupture, thereby reducing the use effect. Appropriate use the low speed stirring blades for stirring, such as anchor type, frame type, multi-layer plasma type etc. The stirring speed is about 60 revolutions per minute. Delivery also should avoid using high-speed centrifugal pump, more suitable adopts the piston pump and diaphragm pump.
3. Evenly disperse feeding. The key link of polyacrylamide dissolved is evenly disperse feeding. After starting the mixer, it is better to use mechanical vibration sieve feeding (number of the sieve mesh is 10 meshes), should try to avoid forming the insoluble particles such as "big lumps" and "fish eyes", make the polyacrylamide fully dissolved, play the good use effect.
4. Avoid contacting with the iron. In the system of dissolution, stirring, delivery and adding, it is better to use the materials of plastic, enamel, aluminum and stainless steel etc..
5. Keep the operation place dry, avoid polyacrylamide scattered on the ground, in case of slippery conditions, should be cleared in time, prevent slippery fall.
