Product Series
Polyacrylamide for urban sewage is a high-efficiency flocculating agent for different urban sewage treatment by hundreds of millions of polyacrylamide manufacturers. It is soluble in water, white particles or powder, non-toxic, non-corrosive, and has good thermal stability. It has extremely high special effects in dealing with silt precipitation and silt compact dehydration. Therefore, we are divided into two kinds of properties of polyacrylamide:
Cationic polyacrylamide is the most widely used sewage treatment agent in municipal sewage treatment at present. Its main raw materials are acrylamide, DAC or DMC copolymer, which is synthesized at high temperature to form polymer polymer type sewage treatment agent. We usually call it cationic polyacrylamide, also known as cpam.
Non-ionic polyacrylamide, English abbreviation: NPAM, is a water-soluble polymer or polyelectrolyte. This product is mainly used for all kinds of industrial wastewater flocculation settlement, precipitation clarification treatment, such as paper and pulp wastewater treatment, mineral processing and metal smelting process wastewater treatment, iron and steel plant and stone processing plant wastewater treatment.
Steel Plant Special Polyacrylamide
Polyacrylamide PAM for steel mills is a water-soluble polymer. Because of its molecular chain contains a certain number of polar groups, can be suspended by the adsorption of solid particles in water, so that the bridge between the particles or through the charge and the particles to form a large flocculation. Therefore, the anionic polyacrylamide PAM can accelerate the sedimentation of particles in the suspension, there is a very obvious acceleration of solution clarification, promote filtration and other effects.
Paper Mill Special Polyacrylamide
Papermaking special polyacrylamide is widely used as a resident agent, filter aid, uniformity agent, water treatment agent, etc. in the field of papermaking. Its function is to improve the quality of paper, improve the dewatering performance of pulp, improve the retention rate of fine fibers and fillers, reduce the consumption of raw materials and environmental pollution. The effectiveness of use in papermaking depends on the average molecular weight, ionic nature, ionic strength, and reactivity of the other copolymers. Non-ionic PAM is mainly used to improve the filterability of pulp, increase the strength of dry paper, and improve the retention rate of fiber and filler; anionic copolymer is mainly used as dry and wet reinforcing agent and retention agent of paper; cationic copolymer is mainly used for papermaking wastewater treatment and filtration aid, and it also has a good effect on improving the retention rate of filler. In addition, polyacrylamide PAM is also used in papermaking wastewater treatment and fiber recycling.
Special Polyacrylamide for Printing and Dyeing Factory
Printing and dyeing factory special polyacrylamide is a composite high molecular polymer. It can effectively clarify the coal washing water, make the fine particles in the water quickly agglomerate and settle, and improve the recovery of peat, so as to save water and prevent pollution. The problem of sludge disposal produced by printing and dyeing wastewater makes manufacturers have a headache. Printing and dyeing sludge is generally high in inert substances. For example, the sludge produced by Denim and clothing washing and bleaching wastewater has a high sand content, while the content of organic matter and pathogenic bacteria is low, and the calorific value is low. Generally, the content of heavy metals is high (compared with the sludge produced by urban domestic sewage). As the printing and dyeing industry itself due to the use of raw materials, product varieties, product processing methods and other different sludge components are not the same, the use of sulfur dyes enterprises, the content of sulfide is bound to be higher. Therefore, the selection and dosage of printing and dyeing sludge treatment should be treated differently according to the different sources of sludge, starting from the aspects of sewage treatment scale, sludge yield, pharmaceutical source, pharmaceutical dosage, operating cost, moisture content of mud cake, etc., according to local conditions, comprehensive consideration.
Non-ionic polyacrylamide (NPAM)
Non-ionic polyacrylamide (NPAM) is a water-soluble high molecular weight low ionic linear polymer. Non-ionic polyacrylamide (NPAM) has a very obvious effect on accelerating the clarification of the solution and promoting filtration. Non-ionic polyacrylamide (NPAM) is widely used in coal mine washing, textile industry auxiliaries, weak acid sewage treatment, metallurgical beneficiation, chemical grouting agent, soil humectant, etc.
Zwitterionic Polyacrylamide (ACPAM)
Zwitterionic polyacrylamide molecules contain cationic and anionic base, it has the general characteristics of the use of cationic flocculants, showed more excellent performance. This kind of flocculant can be used in a wide range of pH value, has a higher water filtration capacity, the bottom of the filter cake moisture content, can also be used for strong acid leaching ore or from the metal containing acid catalyst to recover valuable metals. Zwitterion is by no means a mixture of anionic and cationic types. If the cationic polyacrylamide and anionic polyacrylamide used in conjunction with the reaction will produce precipitation. So zwitterionic products are the most ideal.
Electroplating wastewater treatment
Plating waste water sources: plating parts cleaning water, waste plating solution, equipment cooling water and other waste water. The characteristics of sewage, this kind of wastewater is generally strong acid water quality, the water quality is complex, the composition is not easy to control, which contains chromium, cadmium, nickel, copper, zinc, gold, silver and other heavy metal ions and cyanide, some of which are carcinogenic, teratogenic, mutagenic and highly toxic substances.
