Defoamers (Defoaming agents) are widely used and of various kinds; the application of water treatment defoamers accounts for more than 60% of the defoamer market share, so how to choose the right products among many water treatment defoamers? How to master the standard of adding amount of defoamer in water treatment? The selection of bad defoamer is not only a waste of time and money, but also can not solve the bubble problem. It will even affect the benign operation of the water treatment system itself. How to choose defoamer for water treatment 1. water treatment defoamer should be insoluble or difficult to dissolve in foam solution to destroy foam. Water treatment defoamer should be concentrated and concentrated on the bubble film, and the situation of foam suppression should always be maintained in such a state. In order to achieve the best effect, the molecule of its active component must be strong hydrophobic and weak hydrophilic, and the HLB value should be controlled in the range of 1.5-3. Therefore, the defoamer is supersaturated in the foaming solution. Only when it is insoluble or insoluble can it easily reach supersaturation. Insoluble or insoluble, it is easy to gather at the gas-liquid interface, it is easy to concentrate on the bubble membrane, and it can play a role at a lower concentration. 2. The surface tension of defoamer is lower than that of foaming solution. Only when the surface tension of water treatment defoamer is lower than that of foaming solution, the defoamer particles can be immersed and expanded on the bubble membrane. It should be noted that the surface tension of foaming solution is not the surface tension of solution, but the surface tension of foaming solution. 3. the defoaming agent for water treatment requires a certain degree of affinity with the foaming liquid, because in the process of defoaming is actually the competition between the rate of collapse of the foam and the rate of foam formation, so the defoaming agent for water treatment must be able to disperse quickly in the foaming liquid so as to be able to play a role in the larger range of foaming liquid quickly. Therefore, in order to make the defoamer diffuse quickly, the active components of defoamer must have a certain degree of affinity with the foaming solution. The active components of defoamer are too close to the foaming solution, which will dissolve; too sparse and difficult to disperse. Only when intimacy is appropriate, the effect will be good. This is also the technical point of water treatment foaming agent 4. There must be no chemical reaction between defoamer and foaming solution. If defoamer reacts with foaming solution, on the one hand, defoamer will lose defoaming effect, on the other hand, it may produce harmful substances, which will affect the growth of microorganisms and the operation of water treatment system. 5. The volatility of defoamer in water treatment must be small and the time of foam suppression must be long. Standard addition amount of defoamer for water treatment 1. Defoamer for alcohol water treatment: the amount of alcohol defoamer is generally in the range of 0.01-0.10%. 2. Defoamer for oil water treatment: the amount of oil defoamer is 0.05-2%, and the amount of fatty acid ester defoamer is 0.002-0.2%. 3. Amide defoamer for water treatment: the effect of amide defoamer is better, and the addition amount is generally within 0.002-0.005%. 4. Defoamer for phosphoric acid water treatment: phosphoric acid defoamer is most commonly used in fiber and lubricating oil, with the addition of 0.025-0.25%. 5. Amine water treatment defoamer: amine defoamer is mainly used in fiber processing, with the addition amount of 0.02-2%. 6. Defoamer for ether water treatment: the amount of defoamer is 0.025-0.25%. We also need to determine our own foaming system, which is water-based system or oil-based system. The most suitable and economical defoamer product can be obtained by choosing the proper defoamer for water treatment, comparing the amount of defoamer added and referring to the price. The amount of defoamer should also be considered. There are many kinds of defoamers, and different types of defoamers need different amounts of additives Shaanxi United Xingchuang International Co., Ltd.

Today [ShaanXi United Xingchuang International Co., Ltd." talk about the common lies of defoamer industry: First: Can desulfurizing defoamer desulfurize? [ShaanXi United Xingchuang International Co., Ltd." thought of reading an article on a website called authoritative, which said that desulfurizer and defoamer can desulfurize and defoamer, which is absolutely a big lie and a serious misleading. Desulfuration defoamer is only named because this product is used in desulfuration industry, not that this defoamer can desulfurate. In addition, defoamers are not required for all desulfurization processes. If you are a dry desulfurizer, you do not need to use defoamers at all. I think many defoamer manufacturers are reluctant to tell you, because this will reduce their orders. Second: Do you really have a universal defoamer? Of course, the answer is no, even in the same industry, but because of different technologies, the foaming materials will be different, and the suitable defoamers will be different naturally. How can there be a general defoamer king? Take sewage treatment as an example. Sewage treatment can not solve the problem with only one defoamer. Different foaming substances and different samples are selected. If your sewage is ordinary sewage, organosilicon products can be considered, but if it is microbial sewage treatment, other products should be selected, so how can there be a general theory? Third: How many months, or even years, can defoamers be added in a small amount at a time? This is the most typical lie. Some manufacturers make such slogans in order to publicize their products, but you have to know that you must be cheated, because it is impossible for defoamers to simulate every production process during the R & D test. The R & D process is carried out in the laboratory, using a general environment to conduct performance test, and the test methods are shaking bottles and bulging Gas, circulation bubbling, can not come to the conclusion that you can use this technology field for several months. Of course, there are many other misunderstandings,We will not list them one by one, but first summarize a few points to share with you. In a word, when we choose defoamers, we should focus on the production process, specific foaming substances, and we should know that only the right medicine can completely solve the problem, otherwise we will always solve the surface phenomenon, not the root.

The polyaluminium chloride sold on the market is quite miscellaneous, because each manufacturer's production process and raw materials are different, and the color produced is also different. Generally, there are six colors of polyaluminium chloride, including white, light yellow, golden yellow, brown, brown, and coffee. Here are six different colors for different purposes. Differences of six PACS 1. White polyaluminium chloride The newly developed new water purification material is widely used in food, drinking water, urban water supply, precision manufacturing water purification, paper industry, medicine, sugar refining, cosmetics additives, daily chemical industry, etc., with very high purity and the highest price. 2. Light yellow polyaluminium chloride The medium and high series products, next to white polyaluminium chloride, are mainly used for drinking water treatment, in which the content of heavy metals is strictly limited, especially the drinking water grade polyaluminium chloride products produced by us, the water treated with it is clear and free of precipitation, the content of Al2O3 is about 30 (± 0.5), the powder is fine, the particles are uniform, the flocculation effect is good, the purification is efficient and stable, and the dosage is small Low cost, is a long-term cooperation of major water plants dedicated water treatment flocculant. 3. Golden yellow polyaluminium chloride It is the most widely used polyaluminium chloride in the market at present. It is an efficient flocculant for sewage treatment, with good flocculation effect. Therefore, it is the best choice for industrial water supply, industrial wastewater, industrial water circulation and urban sewage treatment. 4. Brown, brown and coffee polyaluminium chloride It is a kind of water treatment product produced according to the special requirements of individual customers for water treatment, in which the iron content is higher than other polyaluminium chloride product series, so the color is darker than golden yellow. For low temperature, low turbidity and high algae sewage, it is mainly used for drinking water, urban water supply, industrial water purification and other aspects of treatment. Operating storage considerations: 1. In operation, the water purification process of polyaluminium chloride is generally divided into three stages. The three stages are coagulation stage, flocculation stage and sedimentation stage. In the coagulation stage, when the liquid medicine is injected into the coagulation vessel and the raw water is quickly coagulated, micro alum will form in a very short time. At this time, the water body becomes more turbid, which requires that the water flow can produce intense turbulence. Then the PAC enters the flocculation stage, which is the process of alum growth and coarsening. Appropriate turbulence degree and enough residence time (10-15min) are required. At the later stage, a large number of alum clusters can be observed to sink slowly, forming a clear surface layer. When the flocculant is in the settling stage, it is the settling process of the flocculant in the settling tank. The water flow is required to be slow. In order to improve the efficiency, the inclined tube or plate settler is generally used. A large number of coarse alum flowers are blocked by the inclined tube (plate) wall and deposited at the bottom of the tank. The upper water is clear water, and the remaining alum flowers with small particle size and small density slowly decline while continuing to collide with each other, At the later stage, the residual turbidity remained unchanged. 2. PAC must be stored in a dry, moisture-proof and heat-resistant place (< 80 ℃ do not damage the package, the product can be stored for a long time). 3. Polyaluminium chloride products must be dissolved before use, and corrosion-resistant materials shall be used for dissolution equipment and dosing facilities. 4. The effective storage period of liquid products and solid products of polyaluminium chloride is half a year and two years respectively. The solid products can still be used after being damped.

Polyacrylamide is a kind of water-soluble polymer, which has many valuable properties such as flocculation, thickening, shear resistance, resistance reduction and dispersion. These properties have different emphases with different derivative ions. Therefore, it is widely used in oil production, mineral processing, coal washing, metallurgy, chemical industry, paper making, textile, sugar making, medicine, environmental protection, building materials, agricultural production and other departments. So how to make the use effect of polyacrylamide reach the predetermined goal? Cationic polyacrylamide is a water-soluble linear polymer copolymerized by cationic monomer and acrylamide. It is mainly used to flocculate negatively charged colloid, which has the functions of turbidity removal, decolorization, adsorption, adhesion, etc. Anionic PAM uses its molecular chain containing polar groups to adsorb suspended solid particles, so as to bridge between particles or agglomerate particles to form large flocculants through charge neutralization. When using polyacrylamide, we should pay attention to the following points in order to greatly improve its treatment effect: 1. Water temperature: when the water temperature is low, the hydrolysis of inorganic salt coagulant is endothermic reaction, which is not conducive to the hydrolysis of coagulant such as aluminum sulfate, and when the water temperature is low, the viscosity of water is large, the Brownian motion intensity of particles is weakened, which is not conducive to the destabilization of colloid and the growth of flocculent. When aluminum salt is used as coagulant, the water temperature has a greater impact on the coagulation effect; when iron salt is used as coagulant, the water temperature has little impact on the coagulation effect 2. PH value: the pH value in water has a direct impact on the hydrolysis of coagulant, the solubility of insoluble salt formed and the coagulation effect. Different coagulants have different requirements for the pH value when they have coagulation effect 3. Dosage of coagulant: adding coagulant to the water is the premise of removing colloidal impurities in the water. As for the range of adding coagulant, it depends on different water quality, and the beaker test should be made 4. Ions or impurities in water: the amount and type of counter ions in water, turbidity, TOC, Doc or chroma in water also have a direct impact on the determination of coagulant amount and coagulation effect 5. Hydraulic conditions: the place where coagulant and coagulant aid are added, the mixing effect after drug addition, the hydraulic conditions formed in the dosing point and clarification equipment, etc. have an impact on the coagulation effect Shaanxi United Xingchuang International Co., Ltd.

PAM is a kind of polyelectrolyte synthesized on the basis of acrylamide and its copolymers, which is a high molecular weight water-soluble polymer. Generally, it can be divided into cation PAM, anion PAM and non-ionic PAM according to the charge properties. Its performance has four categories. I.flocculation When PAM is used for flocculation, it is related to the surface properties of the flocculated substances, especially the potential, viscosity, turbidity and pH value of the suspension. The potential on the surface of the particles is the reason why the particles are blocked by adding PAM with opposite surface charge, which can reduce the potential and agglomerate. II. Adsorption bridging PAM molecular chain is fixed on the surface of different particles, and polymer bridge is formed between the particles, which makes the particles aggregate and settle. III. surface adsorption Adsorption of polar group particles on PAM. IV. enhancement PAM molecular chain and dispersed phase are linked together to form a network through various mechanical, physical and chemical actions. High polymer polyacrylamide is one of the most widely used water-soluble polymers because of its high viscosity. Shaanxi United Xingchuang International Co., Ltd.

How to Solve the Caking Phenomenon of Flocculant PAM in Water In order to reduce the agglomeration of flocculant in water, we need a method of dosing. In the preservation of anti-caking should pay attention to, must be placed in a cool, dry, ventilated environment. If it is in the process of dissolving, add half of the water in the pool first, then stir evenly and slowly add dry polyacrylamide powder at the same time. Polyacrylamide flocculant is an organic polymer flocculant. Its molecular weight is relatively large. Generally, it is in the order of millions or tens of millions. When it dissolves, it will swell first and then dissolve slowly. If the amount of polyacrylamide is large and it can not be added evenly and slowly, polypropylene will dissolve slowly. The acrylamide first contacts the water part, then begins to swell, then the surface area becomes larger, and then encapsulates the untouched part (you can peel off the fished flocs, the middle is dry, not contaminated with water), so some insoluble polyacrylamide groups are formed. At present, most sewage treatment plants generally use manual dosing (if the automatic feeder is used instead, it not only saves manpower, but also avoids this situation as much as possible). It is suggested that the water should be stirred up first, and then slowly and evenly added above the water column washed out from the intake, so that the medicine can be flushed into the water along the current, so as to reduce the probability of agglomeration, in addition, the contact between the medicine and the inner wall of the dissolving tank should be avoided as far as possible. We can fully dissolve the flocculant powder in the process of using the above-mentioned points. The combination of flocculant and wastewater treatment equipment makes wastewater treatment more effective and effectively solves the problem of wastewater treatment. Therefore, when adding medicine, pay more attention to the cooperation between adding medicine and equipment to achieve the greatest effect. Shaanxi United Xingchuang International Co., Ltd.

How can Poly Aluminium Chloride (PAC) play an effective role Poly Aluminium Chloride (PAC) is a new water purification material, inorganic polymer coagulant, with adsorption, coagulation, precipitation and other properties. Although Poly Aluminium Chloride (PAC) has some shortcomings, it has many advantages, such as less dosage, less sludge, high turbidity removal, little impact on the effluent pH and so on. It is an ideal flocculant in sewage treatment. So how can Poly Aluminium Chloride (PAC) play an efficient role? The following Shaanxi United Xingchuang International CO., LTD. (polyaluminium chloride supplier) for your detailed introduction. Polyaluminium chloride(PAC) is used as water treatment material. In order to achieve better use effect and economic benefits, users can determine the appropriate dosage according to different turbidity of raw water, different seasons and different pool types. The liquid and solid products can be directly added water to form 3-5% water solution (calculated by the content of AL2O3), and the general dosage is 10-20PPm. For polyaluminium chloride (PAC) used in paper sizing, the dosage is one of three parts of aluminium sulfate, which is calculated as 2-3% according to absolute dry paper, and is used in decolorization and clarification of sugar industry. Firstly, the product was prepared into 3-5% aqueous solution (calculated according to the content of AL2O3), and then added to the decolorized sugarcane juice with the dosage of 5-10PPm. Poly Aluminium Chloride (PAC) can effectively remove all kinds of toxic and harmful pollutants in water, its dosage is much lower than that of traditional inorganic coagulant, which reduces the production cost. The operation process is much simpler than the traditional treatment method. It has good low temperature coagulation treatment efficiency and sedimentation efficiency, and can significantly improve solid-liquid separation efficiency and sedimentation. The performance of filtration and sludge dewatering can shorten the residence time of sedimentation tank and increase water production. Shaanxi United Xingchuang International Co., Ltd.

Is it safe to use polyacrylamide for domestic water? Polyacrylamide has a large number of amide groups in its main chain and has high chemical activity. It can be modified to produce many derivatives of polyacrylamide. The products have been widely used in paper making, mineral processing, oil recovery, metallurgy, building materials, sewage treatment, etc. industry. Is it safe to use polyacrylamide for domestic water? Can I use polyacrylamide directly to treat this water? Below Shaanxi United Xingchuang International CO., LTD. (polyacrylamide supplier) for your detailed explanation. The water we use is not the bottled water or bottled water that we usually drink, but the tap water that is commonly used in life. The domestic water is closely related to people's health and quality of life, and its importance is no less than food. Polyacrylamide itself is almost non-toxic, so when it enters the human body, most of it will be excreted with the metabolism of the human body. Although polyacrylamide is non-toxic, the toxicity of polyacrylamide comes from the raw material monomer acrylamide which produces polyacrylamide and the toxic metals entrained in the production process. Acrylamide is a neurotoxic agent that has some damage to the nervous system of animals. National health departments have stipulated that the residual acrylamide content in polyacrylamide industrial products is generally 0.5%-0.05%. In domestic water, the residual acrylamide content in polyacrylamide is below 0.05%. In domestic water, the content of polyacrylamide should not exceed 1 mg/L, and the content of acrylamide should not exceed 0.01 mg/L. It can be seen that the use of polyacrylamide is safe for the treatment of domestic water, but it is necessary to control the amount of use. When used properly, it can be used for the treatment of domestic sewage. Shaanxi United Xingchuang International Co., Ltd.
