Polyacrylamide instructions for use

1, the number of cationic polyacrylamide used in coal washing can be set at 30 kg to 110, the number should be increased, the use of the number set to one hundred to three hundred kilograms more reasonable, electroplating wastewater industry and ordinary Industrial water generally do not exceed 50 kilos. Note: (The use of these types of industries are the number of wastewater per thousand tons)!
2, polyacrylamide in the textile industry.
If the main body of the process using biochemical methods, that is, the remaining sludge dehydration (which may contain some of the initial Sediment), only cationic PAM as sludge dehydrating agent can be.
If the main body of the materialized methods, such as a strengthening, loading magnetic separation process, generally first plus kilograms; chemical industry waste water usage is generally between 50 and 120 kilograms; bleaching and dyeing industry waste water and papermaking Industry's most difficult to deal with waste water PAC PAC, and then add anionic flocculant, and finally add cationic flocculant dehydration. Specific dosage according to the sewage water quality.
There are many sewage treatment stations, sludge dewatering can be added directly PAC or other inorganic flocculants, the frame filter press, especially the electronics factory or a small sewage treatment station is widely used.
When PAM is used as a sludge dewatering agent, the ratio of water to water should be between 0.1% and 0.2%. After dissolving into a glue-like liquid, it is added to the sludge for mixing treatment.
With the ratio of sludge generally 5% - 10%, and some lower, this should be based on the concentration of sludge to determine, it is best to determine the best dosage and the use of models by the scene of the beaker experiment. Different sludge, different pharmaceuticals, different equipment, different management levels, sludge treatment effect is different.
3, sewage treatment plant with cationic polyacrylamide as sewage sludge dewatering agent. In communicating with customers, customers often ask questions about the amount of sludge dewatering agent added during the dewatering of sewage sludge. Relatively accurate to know the sludge dewatering agent dosage issues, first of all to understand these parameters, the sludge moisture content, moisture content of mud cake, into the mud volume, into the drug concentration, drug concentration
