Polyacrylamide (PAM) points: anionic, cationic, nonionic, amphoteric polymers, to improve the treatment process sedimentation, clarification, filtration, centrifugation process efficiency. Cationic polyacrylamide (PAM) product form of white powder, granules. Features cationic polymer flocculant is a water-soluble linear polymers, the molecular weight between 600-1200 Wan. Cationic PAM in acidic or alkaline medium showed a cationic, this can effectively suspended particles of sewage effluent with a negative charge by a flocculation. The main purposes: 1, sewage water treatment using aluminum, iron and other inorganic coagulants, flocculants within sewage treatment systems, such as the need to handle more than the clarifier processing power or because of other factors caused by water floc late settlement drift out, just add 0.1-0.2ppm of PAM coagulation, sedimentation can be significantly improved. Moreover, the water COD and color indicators will be significantly improved after treatment. The idea is to require the use of inorganic coagulants and flocculants to be better with the product suitability. 2, sludge thickening can be reduced using biochemical pool 0.3-2ppm concentrated pool of sludge and sludge water ratio and improve the utilization of biochemical pool and sludge thickening pool. You can sludge concentration increased from 3 -10g / L to 30 -100g / L, greatly reducing the volume of sludge dewatering process is the next step to improve the efficiency of sludge dewatering equipment and personnel. 3, various sludge dewatering concentrated sludge shall be dewatered using PAM dry. Sludge dewatering process and fortunately the PAM dosage and drying of dehydrated sludge cake kind of view differ, it shall be for a variety of different types of PAM product testing and selection anionic polyacrylamide (PAM) anionic polyacrylamide flocculant, mainly used for inorganic solid-based treatment to neutral suspension. In the municipal and industrial wastewater treatment, waste water is used to improve the removal of suspended solids, COD and phosphate. In the primary settling tank wastewater into 0.25mg / L hydrolyzed polyacrylamide, suspended solids and COD removal efficiency can be increased to 66% and 23%, respectively; in the secondary wastewater settling tank was added 0.3mg / L anionic flocculation agents, suspended solids and BOD removal can be increased to 87% and 91%, while phosphorus removal from 35% to 91% in drinking water and domestic wastewater treatment, for clarification of surface water, washing waste clarification and filtrate adjustment process. In mining for coal washing water clarification and flotation tailings, coal filtration, tailings (residue) dehydration, flotation tailings clarification, the hot solution concentrate thickening and filtration, potash and flotation process fluid clarification flotation tailings clarification suddenly barite fluorite, but also raw brine for salt processing, clarification and processing phosphate ore reclaimed water sludge dewatering and the like. In the steel and metal manufacturing industry, for the open-hearth furnace gas wash water purification painted clarify powder metallurgy plants and pickling plant wastewater purification and plating waste liquid electrolyte clarification. Product Overview The product is in front of acrylamide alkali homopolymerization cohydrolysis process, the granulation, drying, crushing, product appearance of white powdery solid fine particles or anionic polyacrylamide 1, mainly used as flocculants: for suspension High particulate, coarse, concentration, particle with a positive charge, water PH value is neutral or alkaline water, since the anionic polyacrylamide molecular chain containing a certain amount of polar functional adsorption of suspended solid particles that stand between particles Bridge formation of large flocs. It accelerated subsidence suspension particles have a very clear clarification back fast solution to promote filtering and other effects. The products are used in chemical industrial waste water, waste water treatment, municipal sewage treatment. Water industry, the high turbidity water purification, Shen Qing, coal, mineral processing, metallurgy, steel, zinc, aluminum industry, electronic industry and other treatment. 2, for textile sizing agents, serous stable performance, down less pulp, fabric breakage rate is low, clean cloth. 3, for the petroleum industry, oil, drilling mud, waste mud treatment, to prevent water channeling, reduced friction, enhanced oil recovery, EOR has been widely used. 4, for the paper industry, one is to increase filler and pigment retention rate. In order to reduce the loss of raw materials and environmental pollution; second is to improve the strength of paper (including dry strength and wet strength), In addition, the use of PAM can also increase the tear resistance of paper and porous, so as to improve the visual and print performance, but also with Food and Tea in wrapping paper. Nonionic polyacrylamides PAM is nonionic homopolymerization of acrylamide formed. High purity, good solubility, high molecular weight, effective PH range 1-8. Main purposes: 1, mainly used in sewage treatment, sewage acidic when using this product appropriate. With inorganic coagulant poly aluminum, aluminum sulfate used in conjunction. 2, used in metallurgical processing, such as Mn ore selection, Cu flotation, with about 2ppM. Agglutination bauxite ingredient may also be using this amount of 15 p pM. 3, textile and chemical fiber oar, as with PAM-NSG-1, with a number of other chemicals for the textile paddle, can increase permeability and anti-static products, or directly for the pastes. 4, and with bentonite can be used as soil water sand fixing agent. Planting trees on hillsides, sand dust and sand fixation, very effective. 5, with the goods and wood fiber can be used as profile control plugging agent field. Zwitterionic polyacrylamide zwitterionic appearance of white powder, effective PH range 1-14, depending on the application is divided into two processes: one is by copolymerization of acrylamide, acrylic acid, cationic monomers together; the other is a non- polyacrylamide modified by ion. The molecular structure of their products, both cationic, anionic there, salt, good temperature resistance. The main purposes: 1, oil control plugging agent, and a crosslinking agent, stabilizer, coagulant combined effects produce high-strength adhesive has important coagulant polymer gel and resin gel plugging agent. It clogged pore and fracture by attaching physical blockage effect, adjust the ratio, can control the gel time to adapt to different geological conditions clear. 2, all kinds of oil, organic, inorganic, water, sewage treatment complex. In PH fluctuating sewage system, a single ionic polyacrylamide effect is far less than the synergistic effect of zwitterionic, if the cationic polyacrylamide used in conjunction with anionic polyacrylamide is reacted to produce precipitation. So zwitterionic product is ideal. 3 for sludge dewatering. 4 for paper chemicals
