Spray-drying polymeric aluminum chloride has better water treatment effect
Compared with ordinary polymeric aluminum chloride, spray-dried polymeric aluminum chloride has better adsorption performance, larger flocculating block, settling effect and better water quality after treatment. Generally spray-dried polymeric aluminum chloride adopts more advanced production technology, spray-dried polymeric aluminum chloride is also divided into drinking water-grade polymeric aluminum chloride and industrial-grade polymeric aluminum chloride and food-grade polymeric aluminum chloride. Drinking water grade polychlorinated aluminum is mainly used for people's daily drinking water, industrial grade polychlorinated aluminum is mainly used for industrial wastewater treatment, and food grade polychlorinated aluminum is used for food additives and medical aspects.

Factors affecting the flocculation effect of polymeric aluminum chloride
Polymerized aluminum chloride is a kind of water purification material we commonly use, we should pay attention to these influencing factors when using, so that polymerized aluminum chloride play a better role!1, water temperature,2, pH value3, coagulant dosage

Polymerized aluminum chloride in the various industries have what use?
First of all, in the water treatment industry, most of the polymerized aluminum chloride is used in water treatment, including various types of sewage, industrial wastewater and drinking water purification and other aspects, polymerized aluminum chloride in the water treatment industry is also a very large amount. In the mining industry, polymerized aluminum chloride can be used for various types of ore screening, on the one hand, to improve the separation of water and ore, on the other hand, it can also produce sludge dewatering. In the oil mining industry, the use of polymerized aluminum chloride and polyacrylamide as oil mining oil repellent, water plugging agent and other uses. In the paper industry, polymerized aluminum chloride can be used as a sizing agent, retention aid, capture agent and so on.

Amount of polyacrylamide per ton of sewage
Product selection, the type of polyacrylamide determines the amount of use, using low molecular weight and high molecular weight polyacrylamide, the dosage is still a little different, although not the higher the molecular weight effect is better, but in the dosage of high molecular weight polyacrylamide dosage will be much less, so the comprehensive down or high molecular weight cost-effective some; sewage quality and concentration, different nature of sewage, or different concentrations of sewage will affect the use of polyacrylamide. For example, the same is mineral processing sewage, the sewage sediment content is different will also affect the amount of polyacrylamide, the same sludge content, different water quality polyacrylamide use effect is also different; sewage treatment site and process equipment, these factors will also affect the amount of polyacrylamide, high dissolution concentration will cause coagulation difficulty, pharmaceutical High dissolution concentration will make coagulation more difficult and the amount of chemicals used is not easy to control. High dissolution concentration will make coagulation more difficult and the amount of chemicals used is not easy to control. Short dissolution time will lead to waste of chemicals and increase the amount used.

Application of Polyacrylamide in Sludge Dewatering Machine
Henan Xinhuan Water Treatment Materials Co., Ltd., is a manufacturer specializing in the production of polyacrylamide for sludge dewatering. Our models include anionic polyacrylamide, cationic polyacrylamide and non-ionic polyacrylamide. We do sludge dewatering agent selection is mainly based on the charge carried in the sewage water quality to determine the selection process is generally laboratory test, to the manufacturer on the machine test to determine the sludge dewatering polyacrylamide model and dosage, welcome the majority of users to negotiate cooperation.

Polyacrylamide for food processing wastewater treatment
In the process of food factory wastewater treatment, we first filter the large sediment in the wastewater with a grille, then the wastewater flows into the wastewater sedimentation tank,and the PH of the wastewater is adjusted to be neutral, so that its pll value reaches the range of 6-9. In the neutral range of water quality, the role of polyacrylamide can be maximized.There are many processes of wastewater treatment in food factories,large and small. We need to use polyaluminium chloride and polyacrylamide in the sewage precipitation stage to achieve the best sewage treatment effect.Aftera series of treatment processes,the final sewage is treated into clean water, and the impurities deposited at the bottom of the clean water tank need to be pressed by the filter press.Achieve the purpose of solid-liquid separation. In the process of sludge pressure filtration, if the direct pressure filtration is used, the effect may not be good, resulting in the phenomenon of mud escaping or high water content ofmud cake.In the sludge dewatering stage,we need to use polyacrylamide to modify the sludge.

Industrial grade polymeric aluminum chloride classification and use effect difference
Industrial grade polymeric aluminum chloride can only be used to treat industrial wastewater, because most of the industrial grade polymeric aluminum chloride is produced through the roller drying process, its content is low, more impurities, the effect of industrial wastewater treatment as long as it can meet the national sewage discharge standards.

Polymerized aluminum chloride is used in this way, so that it can play the greatest efficacy
Polyaluminum chloride characteristics: 1, flocs form quickly, has good activity, and has good filtration. 3, do not need to add alkaline additives, such as deliquescence, the effect remains unchanged. 3, to adapt to the width of the value of PH, adaptability and versatility. 4, the treated water has less salt. It can remove heavy metals and radioactive substances from water pollution.6, Highly efficient ingredients, easy to store, transportation.

Polymeric aluminum chloride used for dyeing wastewater decolorization effect is obvious
Polymerized aluminum chloride (PAC) is a widely used inorganic flocculant, but it exists in a large amount, if the polyacrylamide and polymerized aluminum chloride synergistic effect, will greatly reduce the amount of PAC dosage. And can achieve good treatment effect, low cost and other characteristics. Printing and dyeing or dyestuff wastewater after biochemical treatment of chromaticity is often difficult to meet the standard, the use of polymerized aluminum chloride for deep decolorization treatment effect is better.
