Anionic polyacrylamide AN934 AN945 AN905 dosage and usage

Polyacrylamide is mainly divided into anions, cations and non-ions, they are not the same in the use of the amount, and for each industry usage and dosage is not the same, the following to give you a detailed explanation of anionic polyacrylamide dosage and usage:

Anionic polyacrylamide AN934 AN945 AN905 dosage and usage


Polyacrylamide is mainly divided into anions, cations and non-ions, they are not the same in the use of the amount, and for each industry usage and dosage is not the same, the following to give you a detailed explanation of anionic polyacrylamide dosage and usage:


The amount of anionic polyacrylamide used for coal washing can be set between thirty kilograms and one hundred and ten kilograms; The amount of waste water used in the chemical industry is generally between 50 and 120 kilograms.


The wastewater of bleaching and dyeing industry and papermaking industry are difficult to treat, so the amount of use should be increased. It is reasonable to set the amount of use at 100 to 300 kilograms, and the water used in electroplating wastewater industry and ordinary industrial water should not exceed 50 kilograms.


Domestic sewage according to the treatment method of different desliming flocculant is not the same.


If the process body adopts biochemical method, that is, residual sludge dewatering (may contain some initial sludge), only cationic PAM is needed as sludge dehydrating agent.


If the process body adopts physical and chemical methods, such as strengthening, loading magnetic separation and other processes, generally, PAC is added first, then anionic flocculant is added, and cationic flocculant is added for dehydration. Specific dosage should be determined according to the quality of sewage.


PAM as sludge dehydrating agent is generally used with water ratio between 0.1%- 0.2%. After it is dissolved into a glue-like liquid, it is added to the sludge for mixing treatment.


The ratio of sludge to sludge is generally 5%-10%, some lower, according to the concentration of sludge to determine, through the beaker experiment to determine the dosage and use model. Different sludge, different agents, different equipment, different management level, sludge treatment effect is different.


Cationic polyacrylamide is used as dehydrating agent for sewage sludge operation in sewage treatment plant.


In the process of communication with the customer, the customer often asked about the dosage of sludge dehydrating agent in the process of sewage treatment sludge dewatering.


To know the relative accuracy of the dosage of sludge dehydrating agent, first understand these parameters, the moisture content of sludge, mud cake moisture content, mud quantity, dosage, dispensing concentration, etc.
