In the wastewater pretreatment should be how to choose (anionic, cationicpolyacrylamide)
The synthesis process of physical properties of PAM: PAM polyacrylamide byacrylonitrile and water in skeletal copper catalyst under the action of directreaction of polyacrylamide by ion exchange polymerization drying, and other processes to obtain the product, technology introduction as follows: Catalyst:catalytic hydration of CH2=CHCN+H2O wet degree CH2=CHCONH2nCH2=CHCONH2- polymerization initiator -CH2CHCONH2
Polyacrylamide industrial use: polyacrylamide (PAM) with high molecular weight,good water solubility, molecular weight and can be adjusted, the introduction of various ionic groups in order to obtain a specific performance. Low molecular weight is dispersed material effective thickener or stabilizer, high molecular weight flocculant is important, it can produce hydrophilic and water insoluble gel,which for many groups of surface dissolved material has good adhesion. Due to the above properties of PAM are widely used in flocculation and thickening, drag reduction, quasi glue, adhesive, scale and other fields.
Anionic polyacrylamide according to different uses and users of the product performance requirements, can choose to use different molecular weight.
In the industrial wastewater treatment, especially for the suspended particles,coarse, high concentration, particle with positive charge, water pH value is neutral work alkaline sewage such as iron and steel plant wastewater,electroplating factory waste water, metallurgy wastewater, coal washing wastewater and sewage treatment effect is very good. In drinking water treatment. A lot of water plant of our country water from river river less and mineral content high, compare the turbidity, although after precipitationtreatment, but is still not up to the requirements, needs adding flocculant, canmake the water clear, a lot of water plant using inorganic flocculants, but adding capacity, causing sludge volume increases the effect is not good, use anionic polyacrylamide flocculant, dosage is one of the 50 inorganic flocculation effect but is inorganic flocculant several to several dozen times, especially my company production of polyacrylamide, residual monomer has reached the food grade(less than 0.05%), close to the advanced level, non-toxic, for the treatment of drinking water is more suitable for organic. Pollution serious river and anionicpolyacrylamide with better effect to use. Recovery of polyacrylamide used as loss of starch and starch and alcohol lees factory the. Now a lot of starch factorywastewater discharged in starch is very high, after discharging, affect the environment, waste of resources, the addition of PAM, so that starch sedimentation, sediment by filter press into cake class can be used as feed,distiller's grains large quantities of alcohol factory is used in this process, a Heilongjiang alcohol plant is polyacrylamide flocculants, of distiller's grainsrecycling and achieved great economic benefit. Polyacrylamide is used as ablocking agent for profile control and water plugging in oilfield, three oil displacing agent. Polyacrylamide is used as papermaking additives, PAM use in paper making is very wide, can be used as a long fiber papermaking dispersant, dry and wet strengthening agent, retention, filter aid and papermaking wastewateretc.
The new type of water treatment agent, polyacrylamide, sewage treatment andwater supply in many occasions, anionic polyacrylamide and cationicpolypropylene matched than using a polyacrylamide alone produced a very significant and synergistic effect, the ability of PAM to reduce the surface tension of Si can be far greater than the same conditions of cationic or anionic exist alone, in order to achieve to reduce the surface tension of the requirements,require the simultaneous use of anionic and cationic polyacrylamide, then both if use undeserved, can produce a white precipitate, lose its effect. While the PAMhas the characteristics of both sexes ions, it can finish with anionic, cationicsynergy, surface without any sediment generation, especially the nature of thewater quality situation is more complex or water change frequently, the use of PAM as a flocculant is more convenient, the effect is more good.
Polyacrylamide belongs to a brand of Gongyi City Media Industry Co Ltd,(including a filter, filter source source polyacrylamide polyferric sulfate, filter source poly aluminum ferric chloride etc...) filter is a professional set in R & D,production, sales as one of the water purifying agent company, mainly has: polyaluminum chloride and polyacrylamide, poly aluminum ferric chloride,polymeric ferric sulfate and other water purification materials, we provide the high quality service and products, polyacrylamide, fair and reasonable prices, allows customers to maximize the benefits,
Used in the pretreatment of sewage sludge taken from the Qian Tang River in thesedimentation tank with water, the water plant using polyaluminium chloride PACas flocculant. Sludge through natural concentrated to a solid containing rate of 2.From 7% to 2.8%, by the determination of sludge, organic matter content of 12,1%, such as SJ content is 52.1%, Al. The content of 20, 2%. PAM cationic,anionic and non-ionic three types. Non ionic PAM dissolved speed is slow,generally not used for sludge pretreatment, so the test only selects two kinds ofrepresentative of cationic polyacrylamide and anionic polyacrylamide. Cationic PAM adopt YSC60, molecular weight 12000000, 0.012% acrylamide monomer content. Anionic PAM adopt YSA12, molecular weight 12500000, 0.013% acrylamide monomer content. Two PAM preparation concentration was 0.05%,the refrigerator after using 24hr.
