Polyaluminium chloride and polyacrylamide clever mix Sewage treatment applications, polyaluminum chloride and polyacrylamide how to use to make the best use of the effect? Poly aluminum chloride
wide range of applications to adapt to a wide range of water. Easy to quickly form a large alum, precipitation performance, polyacrylamide molecules with suspended particles dispersed in solution in the bridge adsorption, has a strong flocculation effect, the two together with the use of results with less, the correct mix of chlorine Aluminum polyacrylamide use the following methods: Polyaluminum chloride Main features: Polyaluminum chloride compared with other coagulants, has the following advantages: wide range of applications, to adapt to a wide range of water. Easy to quickly form a large alum, precipitation performance. Appropriate range of PH value wide (5-9), and the water after treatment PH value and alkalinity decreased small. Low water temperature, can still maintain a stable precipitation effect. Alkalinity than other aluminum salts, iron salts, the role of small equipment erosion. Physical indicators: The product is an inorganic polymer coagulant. Mainly through compression double layer, the adsorption of electric neutralization, adsorption bridging, sediment net capture and other mechanisms, the edema of fine suspended particles and colloidal ions destabilization, aggregation, flocculation, coagulation, precipitation, to purification effect. Usage: 1, the solid polyaluminum chloride by 1: 3 water to dissolve into a liquid, add 10-30 times diluted with water to the desired concentration before use. 2, the amount of raw water according to the different turbidity, the determination of the best dosage, the general water turbidity at 100-500mg / L, the dosage of 10-20kg per thousand tons. Main purposes: city water supply and drainage purification: river water, reservoir water, groundwater, industrial water purification, urban sewage treatment, industrial waste water and waste recycling of useful substances to promote coal washing wastewater settling of coal, starch manufacturing starch recovery , Various industrial waste water treatment: printing and dyeing wastewater, leather waste water, fluorine-containing waste water, heavy metal waste water, oily waste water, papermaking waste water, coal washing waste water, mining waste water, brewing wastewater, Fabric enhancement, catalyst carrier, pharmaceutical refining, cement quick-setting, cosmetic raw materials. Packaging and storage 1, lined with plastic bags, the outer layer of plastic film woven bags, bag weight 25kg. 2, stored in a cool, dry place, anti-sun and rain. Polyacrylamide Product Features: The product of the molecular and suspended particles dispersed in solution bridge adsorption, has a very strong flocculation. Density = 1.3 The main purposes: The product has a water-soluble polymer compounds and active acyl groups in the main chain, which in the oil extraction, water treatment, textile printing and dyeing, paper making, mineral processing, coal washing, medicine, sugar, Agriculture and other industries have a wide range of applications, "Hundreds of additives," "universal product," said. 1 Water Treatment: PAM in the water treatment industry applications include raw water treatment, sewage treatment and industrial water treatment in three areas. In the raw water treatment, PAM and activated carbon used in conjunction, can be used for the living water suspended particles in the cohesion and clarification; in sewage treatment. PAM can be used for sludge dewatering; in industrial water treatment, it is mainly used as a prescription medicine. In the raw water treatment, organic flocculants PAM instead of inorganic flocculants, even without the transformation of sedimentation tanks, water purification capacity can be increased by 20% or more. Therefore, at present, many large and medium-sized cities use PAM as a supplement when water supply is poor or their water quality is poor. In sewage treatment, the use of PAM can increase the reuse rate of water reuse. 2 Oil Production: It is widely used in drilling, well completion, cementing, fracturing, enhanced oil recovery and other oilfield operations in the field of oil drilling, mainly for drilling mud materials and increasing oil recovery rate. Loss of filtration, rheological regulation, gelation, diversion, profile adjustment and other functions. At present, China's oilfield mining has entered the middle and late stages, in order to improve the recovery rate of crude oil, the main promotion of polymer flooding and ASP flooding technology. By injecting polyacrylamide aqueous solution to improve the flow ratio of oil and water, so that the crude oil content in the recovery increased. At present, foreign polyacrylamide is not much used in oil fields. Due to the special geological conditions in our country, polymer oil displacement technology has been widely used in Daqing Oilfield and Shengli Oilfield. 3 paper areas: PAM widely used in the field of paper-making agents, filter aids, such as the average agent. Its role is to be able to improve the quality of paper, improve the dehydration performance of the slurry, improve the retention of fines and fillers, reduce the consumption of raw materials and environmental pollution. The effect used in the paper depends on its average molecular weight, the nature of the ions, the ionic strength and the activity 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 of fibers and fillers; anionic copolymer is mainly used as paper wet and dry enhancer and retention agent; cationic copolymer mainly For papermaking wastewater treatment and drainage aid role, in addition to improve the retention of the filler also has a good effect. In addition, PAM is also used in papermaking wastewater treatment and fiber recycling.
