Polyacrylamide (PAM) polymer flocculant has been widely used in the water treatment industry, and is deeply loved by users due to its good sewage treatment effect and low cost. Due to the different models and dosages used in various industries, many customers do not know the use and dosage of polyacrylamide (PAM), as well as the specific usage and dosage that customers do not inform the manufacturer when purchasing, which makes customers confused when using it. If used incorrectly, it can increase hassle and cost. Therefore, before purchasing and using, you should familiarize yourself with the usage and dosage to avoid mistakes and waste. The following is a detailed introduction to Henan Laixing Water Purification, and the dosage and usage of polyacrylamide (PAM) will be informed in detail.
1. Usage and dosage of cationic (CPAM).
1. When used for sludge dewatering, the recommended batching concentration is 0.2%, and the dissolution and stirring time is 50 minutes.
2. Before getting on the machine, it is necessary to do a small test to determine the proportions. It is recommended to take 100ml of sewage sample and inject 0.5ml of aqueous solution with a syringe each time. Continuous stirring observation, check the flocculation effect, flocculation speed, supernatant condition, sedimentation effect, etc., and determine the dosage of dosing.
3. It is used in paper mills, chemical sewage, sewage treatment plants, and coal washing plants, with a solid dry powder content of 10-20g/t sewage.
2. Anion (HPAM) dosage and usage
1. When flocculating and precipitating for sewage treatment, the recommended concentration ratio is 0.1%.
2. The recommended mixing time is 40 minutes, and the speed is controlled at 40-60 rpm.
3. It is recommended to do a small test to determine the proportions before operation. It is recommended to take 100ml of sewage sample and inject 0.5ml of aqueous solution with a syringe each time. Continuous stirring observes the flocculation effect, flocculation speed, supernatant condition, sedimentation effect, etc., and determines the dosage.
4. When steel mills, printing and dyeing plants, electroplating plants, coal washing plants, and paper mills are used as dispersants, the consumption of solid dry powder per ton of sewage is 5-10g.
3. Usage and dosage of non-ionic (NPAM).
1. It is recommended to use a proportional concentration of 0.1%, and the dissolution time is about 50 minutes.
2. The method of use is the same as that of anion (HPAM).
Different types of polyacrylamide (PAM), different uses, of course, their dosage is different, although its wastewater treatment capacity is very strong, but its dosage must be mastered. They are used in basically the same way. In order to effectively treat sewage, attention must be paid to controlling the usage and dosage.
