Regarding the selection of inorganic flocculants, most of them should be selected according to the water quality, which is actually very simple, as long as you remember a few points. 1. Industrial sewage, waste water, municipal sewage are generally selected industrial grade polyaluminum chloride, the content is divided into 26-28%, usually waste water treatment is used 26% content, municipal sewage is recommended to use 28% content, the amount of sludge generated will be relatively small. 2....
Although 70% of the earth is water, not much can be used or drunk directly. Our cities have water shortages to varying degrees. Seawater desalination is one of the best ways to solve this problem. Desalination is the conversion of seawater with high salinity into water that can be used for industrial use or drinking. The current desalination methods are distillation and reverse osmosis. The distillation process is generally used in large desalination plants and in places where there is...
What is the structure of core diapers, do not have to go into detail, I believe that every diaper industry practitioners are clear about this new structure to seize the fluff pulp diaper market at a rapid pace in recent years. However, no matter what kind of overwhelming advantage core diapers are currently appearing in front of fluff pulp diapers, it still has not made user complaints about diapers disappear from core structure diapers. We will still hear such complaints about core diapers,...
Is polyacrylamide toxic? Many people who are new to this product have this question. To tell you that polyacrylamide itself is non-toxic, but the acrylamide used in the production process is toxic, to answer this question, first from its production process and production process to analyze. The production of polyacrylamide is mainly made by aqueous solution polymerization -- colloidal sampling -- acrylamide aqueous solution, which is directly polymerized under the action of initiator. The dry...
Polyacrylamide has a good viscosity, has a thickening effect, in Food Additives production can not use the product thickening that? To answer this question, start with the toxicity of polyacrylamide. Polyacrylamide itself is basically not toxic, after it enters the human body, most of it is discharged in the short term, rarely absorbed by the human body, but the raw material of the production of the product acrylamide is toxic, it is difficult to completely transform in the production, the...
◆ Before the formal use of a type of polyacrylamide product, Water Treatment Chemicals, a small test should be carried out to determine the best dosage and conditions of use, when used as a flocculant, the general dosage is 0.1 ~ 0.5ppm. ◆ Polyacrylamide products must be dissolved into a solution before use, so that the polymer chain is fully extended for reserve use. Usually non-ionic and cationic products are diluted to about 0.1%, and the dissolution operation is carried out in a mixing tank...
As a non-renewable energy source, petroleum reserves in the ground are very limited. Under the current water flooding conditions, the oil recovery rate is only 35% to 45%, that is, most of the crude oil remains in the ground after the end of water flooding. How to extract the remaining crude Oilfield Chemicals in the ground to the maximum extent has become an important task for the petroleum industry. "Developing the west and stabilizing the east" is the development strategy of China's...
70% of the earth is water and 30% is land. Water is everywhere in People's Daily life. Industry and agriculture require a large amount of water resources. However, with the development of industry and the progress of human beings, our water resources are also seriously polluted. Although the proportion of water is 70%, how much water is drinkable, Water Treatment Chemicals, and even the drinkable water needs to be treated. Polyacrylamide in Water Treatment Chemicals has many advantages,...
The advantages of organic flocculants such as polyacrylamide are relatively economical and simple to use, but the disadvantages are large dosage, low flocculation effect, and high cost and strong corrosion. So how can it be used economically and effectively? This problem has been plaguing the majority of customers, Noel biology from the customer's point of view, in-depth study of this problem. Flocculant is undoubtedly the most critical factor in the entire process of sewage treatment, and it...

Polyacrylamide is also used in the production of dish soap, what role does it play in the production of dish soap? Polyacrylamide...
One of the factors hindering the development of textile printing and dyeing industry is environmental protection issues, and wastewater treatment is the main problem of environmental protection issues, statistics in 2008, textile wastewater emissions accounted for 10.6% of the national wastewater emissions, emissions 2.3 billion tons, ranking third in industrial emissions, COD emissions of 3.14 billion tons, ranking fourth in industrial emissions. Accounting for 7.76% of the national industrial...
Gelatin is widely used, but wastewater from gelatin production still needs to be treated. According to the gelatin production method, we know that gelatin is mainly produced by alkali method, which produces a large amount of Water Treatment Chemicals in the production process, and the wastewater is high in alkali, high in calcium, high in chlorine, high in COD characteristics, complex water quality and large amount of water. Because gelatin wastewater has such characteristics, the treatment of...
With the improvement of people's living conditions, there are higher requirements for material life, and there is more demand for leather. It also drives the rapid development of leather processing industry in our country. While the development of the leather industry promotes employment and improves people, it also causes a lot of pollution to the environment, especially water pollution. For the sustainable and healthy development of enterprises, Water Treatment Chemicals is a top priority....
The upstream raw materials of polyacrylamide are generally petroleum products (such as DAC, acrylonitrile, propylene chloride, etc.), Water Treatment Chemicals，and the price of oil itself is relatively large, so it is affected by the price of basic chemical products such as petroleum. The following figure shows the structure of the polyacrylamide industry chain Polyacrylamide upstream and downstream industry chain diagram Polyacrylamide upstream and downstream industry chain diagram (Structure...
Polyacrylamide is an organic polymer, which is widely used in oil exploitation, Water Treatment Chemicals, mineral processing, Oilfield Chemicals，paper making and other fields. Polyacrylamide is formed by polymerization of acrylamide monomer. Therefore, the importance of acrylamide production in the polyacrylamide production process is self-evident.

Polyacrylamide，Polymerized Ferrous Sulfate aqueous solution polymerization is the main method used in industrial production Water Treatment Chemicals. The monomer solution in the formulation must be purified by ion exchange. The reaction medium water should be deionized water, and the initiator mainly uses the oxidation-reduction initiator system composed of persulfate and sulfite to reduce the reaction initiation temperature. In addition, a chain transfer agent is needed, and isopropyl alcohol...
Molecular weight of PAM The molecular weight of polyacrylamide mainly refers to the length of the molecular chain, the higher the molecular weight, the longer the polymer chain, the greater the viscosity of the polyacrylamide solution, and the greater the resistance in the solution. It should be noted that it is not the larger the molecular weight and the thicker the product, the better the effect, the actual situation is the need to determine its effect according to the wastewater experiment....
Coal, as the so-called industrial food, plays an indispensable role in the development of the national economy. Affected by the development of new energy technologies and economic development and policies, in recent years, the growth of coal consumption as an energy source has slowed down, but the production and consumption are still at a historical high, and the production and sales are still very large. Whether in the process of production or use, coal carbon will produce a mixture of water...
